   How is yogurt made?

   Background

   Yogurt is a dairy product, which is made by blending fermented milk with various ingredients that provide flavor and color. Although accidentally invented thousands of years ago, yogurt has only recently gained popularity in the United States.

   It is believed that yogurt originated in Mesopotamia thousands of years ago. Evidence has shown that these people had domesticated goats and sheep around 5000 B.C. The milk from these animals was stored in gourds, and in the warm climate it naturally formed a curd. This curd was an early form of yogurt. Eventually, a process for purposely producing yogurt was developed.

   While yogurt has been around for many years, it is only recently (within the last 30-40 years) that it has become popular. This is due to many factors including the introduction of fruit and other flavorings into yogurt, the convenience of it as a ready-made break-fast food and the image of yogurt as a low fat healthy food.

   Manufacturers have responded to the growth in the yogurt market by introducing many different types of yogurt including low fat and no-fat, creamy, drinking, bio-yogurt, organic, baby, and frozen. Traditional yogurt is thick and creamy. It is sold plain and in a wide assortment of flavors. These are typically fruit flavors such as strawberry or blue-berry however, newer, more unique flavors such as cream pie and chocolate have also been introduced. Cereals and nuts are some-times added to yogurts. Yogurt makers also sell products with a varying level of fat. Low fat yogurt, which contains between 0.5% and 4% fat, is currently the best selling. Diet no-fat yogurt contains no fat at all. It also contains artificial sweeteners that provide sweetness while still reducing calories. Creamy yogurt is extra thick, made with whole milk and added cream. Drinking yogurt is a thinner product, which has a lower solids level than typical yogurt. Bio-yogurt is made with a different type of fermentation culture and is said to aid digestion. Yogurt that is made with milk from specially fed cows is called organic yogurt. This type of yogurt is claimed to be more nutritious than other yogurts. Other types of yogurts include pasteurized stirred yogurt that has extended shelf life, baby yogurt made specifically for children, and frozen yogurt.

   The yogurt itself has a generally aldehydic flavor, which is a result of the fermentation process. Since it is made from milk, yogurt is rich in nutrients. It contains protein and vitamins and is a rich source of calcium. In fact, a small container of yogurt contains as much calcium as a third of a pint of milk. In addition to these nutritional characteristics, yogurt is also thought to have additional health benefits. One of the suggested benefits of yogurt is that it acts as a digestive aid. In the body, it is thought that yogurt can encourage the growth of beneficial bacteria in the gut. These organisms help to digest food more efficiently and protect against other, harmful organisms. Another health benefit of yogurt is for people that are lactose intolerant. These people have difficulty digesting milk products however, they typically can tolerate yogurt.

   Raw Materials

   In general, yogurt is made with a variety of ingredients including milk, sugars, stabilizers, fruits and flavors, and a bacterial culture (Lactobacillus bulgaricus). During fermentation, these organisms interact with the milk and convert it into a curd. They also change the flavor of the milk giving it the characteristic yogurt flavor of which acetaldehyde is one of the important contributors. The primary byproduct of the fermentation process is lactic acid. The acid level is used to determine when the yogurt fermentation is completed which is usually three to four hours. The suppliers of these yogurt cultures offer various combinations of the two bacterial types to produce yogurts with different flavors and textures.

   To modify certain properties of the yogurt, various ingredients may be added. To make yogurt sweeter, sucrose (sugar) may be added at approximately 7%. For reduced calorie yogurts, artificial sweeteners such as aspartame or saccharin are used. Cream may be added to provide a smoother texture. The consistency and shelf stability of the yogurt can be improved by the inclusion of stabilizers such as food starch, gelatin, locust-bean gum, guar gum and pectin. These materials are used because they do not have a significant impact on the final flavor. The use of stabilizers is not required however, and some marketers choose not to use them in order to retain a more natural image for their yogurt.

   To improve taste and provide a variety of flavors, many kinds of fruits are added to yogurt. Popular fruits include strawberries, blueberries, bananas, and peaches, but almost any fruit can be added. Beyond fruits, other flavorings are also added. These can include such things as vanilla, chocolate, coffee, and even mint. Recently, manufacturers have become quite creative in the types of yogurt they produce using natural and artificial flavorings.

   The Manufacturing
   Process

   The general process of making yogurt includes modifying the composition of and pasteurizing the milk; fermenting at warm temperatures; cooling it; and adding fruit, sugar, and other materials.

   Modifying milk composition

   * When the milk arrives at the plant, its composition is modified before it is used to make yogurt. This standardization process typically involves reducing the fat content and increasing the total solids. The fat content is reduced by using a standardizing clarifier and a separator (a device that relies upon centrifugation to separate fat from milk). From the clarifier, the milk is placed in a storage tank and tested for fat and solids content. For yogurt manufacture, the solids content of the milk is increased to 16% with 1-5% being fat and 11-14% being solids-not-fat (SNF). This is accomplished either by evaporating off some of the water, or adding concentrated milk or milk powder. Increasing the solids content improves the nutritional value of the yogurt, makes it easier to produce a firmer yogurt and improves the stability of the yogurt by reducing the tendency for it to separate on storage.

   Pasteurization and homogenization

   * After the solids composition is adjusted, stabilizers are added and the milk is pasteurized. This step has many benefits. First, it will destroy all the microorganisms in the milk that may interfere with the controlled fermentation process. Second, it will denature the whey proteins in the milk which will give the final yogurt product better body and texture. Third, it will not greatly alter the flavor of the milk. Finally, it helps release the compounds in milk that will stimulate the growth of the starter culture. Pasteurization can be a continuous-or batch-process. Both of these processes involve heating the milk to a relatively high temperature and holding it there for a set amount of time. One specific method for batch process pasteurization is to heat a large, stainless steel vat of milk to 185° F (85° C) and hold it there for at least 30 minutes.
   * While the milk is being heat treated, it is also homogenized. Homogenization is a process in which the fat globules in milk are broken up into smaller, more consistently dispersed particles. This produces a much smoother and creamier end product. In commercial yogurt making, homogenization has the benefits of giving a uniform product, which will not separate. Homogenization is accomplished using a homogenizer or viscolizer. In this machine, the milk is forced through small openings at a high pressure and fat globules are broken up due to shearing forces.

   Fermentation

   * When pasteurization and homogenization are complete, the milk is cooled to between 109.4-114.8° F (43-46° C) and the fermentation culture is added in a concentration of about 2%. It is held at this temperature for about three to four hours while the incubation process takes place. During this time, the bacteria metabolizes certain compounds in the milk producing the characteristic yogurt flavor. An important byproduct of this process is lactic acid.
   * Depending on the type of yogurt, the incubation process is done either in a large tank of several hundred gallons or in the final individual containers. Stirred yogurt is fermented in bulk and then poured into the final selling containers. Set yogurt, also known as French style, is allowed to ferment right in the container it is sold in. In both instances, the lactic acid level is used to determine when the yogurt is ready. The acid level is found by taking a sample of the product and titrating it with sodium hydroxide. A value of at least 0.9% acidity and a pH of about 4.4 are the current minimum standards for yogurt manufacture in the United States. When the yogurt reaches the desired acid level, it is cooled, modified as necessary and dispensed into containers (if applicable).

   Adding other ingredients

   * Fruits, flavors, and other additives can be added to the yogurt at various points in manufacturing process. This is typically dependent on the type of yogurt being produced. Flavor in non-fruit yogurts are added to the process milk before being dispensed into cartons. Fruits and flavors can also be added to the containers first, creating a bottom layer. The inoculated milk is then added on top and the carton is sealed and incubated. If the fruit is pasteurized, it can be added as a puree to the bulk yogurt, which is then dispensed into containers. Finally, the fruit can be put into a special package, which is mixed with plain yogurt upon consumption.
   * The finished yogurt containers are placed in cardboard cases, stacked on pallets, and delivered to stores via refrigerated trucks.

   Quality Control

   Milk products such as yogurt are subject to a variety of safety testing. Some of these include tests for microbial quality, degree of pasteurization, and various forms of contaminants. The microbial quality of the incoming milk is determined by using a dye reaction test. This method shows the number of organisms present in the incoming milk. If the microbial count is too high at this point, the milk may not be used for manufacture. Since complete pasteurization inactivates most organisms in milk, the degree of pasteurization is determined by measuring the level of an enzyme in the milk called phosphatase. Governmental regulations require that this test be run to ensure that pasteurization is done properly. Beyond microbial contamination, raw milk is subject to other kinds of contaminants such as antibiotics, pesticides or even radioactivity. These can all be found through safety testing and the milk is treated accordingly.

   In addition to safety tests, the final yogurt product is also evaluated to ensure that it meets the specifications set by the manufacturer for characteristics such as pH, rheology, taste, color, and odor. These factors are tested using various laboratory equipment such as pH meters and viscometers and also human panelists.

   The Future

   The future of yogurt manufacturing will focus on the development of new flavors and longer lasting yogurts. The introduction of new flavors will be driven by consumer desires and new developments by flavor manufacturers. The suppliers of the bacterial cultures are conducting research that hints at the development of uniquely flavored yogurts. By varying the types of organisms in the cultures, yogurt is produced much faster and lasts longer than conventional yogurt.

   Additionally, the nutritional aspects of yogurt will be more thoroughly investigated There is some evidence that has shown consumption of yogurt has a beneficial antibiotic effect. It has also been shown to reduce the incidence of lactose intolerance and other gastro-intestinal illnesses. Other purported benefits of yogurt include the reduction of cholesterol, protection against certain cancers, and even boosting the immune system. The research is still not complete on these benefits however, these factors will likely be important in the continued market growth of yogurt.

   10 REASONS YOGURT IS A TOP HEALTH FOOD

   1. Yogurt is easier to digest than milk. Many people who cannot tolerate milk, either because of a protein allergy or lactose intolerance, can enjoy yogurt. The culturing process makes yogurt more digestible than milk. The live active cultures create lactase, the enzyme lactose-intolerant people lack, and another enzyme contained in some yogurts (beta-galactosidase) also helps improve lactose absorption in lactase-deficient persons. Bacterial enzymes created by the culturing process, partially digest the milk protein casein, making it easier to absorb and less allergenic. In our pediatric practice, we have observed that children who cannot tolerate milk can often eat yogurt without any intestinal upset. While the amount varies among brands of yogurt, in general, yogurt has less lactose than milk. The culturing process has already broken down the milk sugar lactose into glucose and galactose, two sugars that are easily absorbed by lactose-intolerant persons.

   2. Yogurt contributes to colon health. There’s a medical truism that states: “You’re only as healthy as your colon.” When eating yogurt, you care for your colon in two ways. First, yogurt contains lactobacteria, intestines-friendly bacterial cultures that foster a healthy colon, and even lower the risk of colon cancer. Lactobacteria, especially acidophilus, promotes the growth of healthy bacteria in the colon and reduces the conversion of bile into carcinogenic bile acids. The more of these intestines-friendly bacteria that are present in your colon, the lower the chance of colon diseases. Basically, the friendly bacteria in yogurt seems to deactivate harmful substances (such as nitrates and nitrites before they are converted to nitrosamines) before they can become carcinogenic.

   Secondly, yogurt is a rich source of calcium - a mineral that contributes to colon health and decreases the risk of colon cancer. Calcium discourages excess growth of the cells lining the colon, which can place a person at high risk for colon cancer. Calcium also binds cancer-producing bile acids and keeps them from irritating the colon wall. People that have diets high in calcium (e.g. Scandinavian countries) have lower rates of colorectal cancer. One study showed that an average intake of 1,200 milligrams of calcium a day is associated with a 75 percent reduction of colorectal cancer. As a survivor of colon cancer, I have a critical interest in the care of my colon. My life depends on it.

   3. Yogurt improves the bioavailability of other nutrients. Culturing of yogurt increases the absorption of calcium and B-vitamins. The lactic acid in the yogurt aids in the digestion of the milk calcium, making it easier to absorb.

   4. Yogurt can boost immunity. Researchers who studied 68 people who ate two cups of live-culture yogurt daily for three months found that these persons produced higher levels of immunity boosting interferon. The bacterial cultures in yogurt have also been shown to stimulate infection-fighting white cells in the bloodstream. Some studies have shown yogurt cultures to contain a factor that has anti-tumor effects in experimental animals.

   NUTRITIP: Yogurt - Good for Young and Old

   Yogurt is a valuable health food for both infants and elderly persons. For children, it is a balanced source of protein, fats, carbohydrates, and minerals in a texture that kids love. For senior citizens, who usually have more sensitive colons or whose intestines have run out of lactase, yogurt is also a valuable food. Elderly intestines showed declining levels of bifidus bacteria, which allow the growth of toxin-producing and, perhaps, cancer-causing bacteria.

   5. Yogurt aids healing after intestinal infections. Some viral and allergic gastrointestinal disorders injure the lining of the intestines, especially the cells that produce lactase. This results in temporary lactose malabsorption problems. This is why children often cannot tolerate milk for a month or two after an intestinal infection. Yogurt, however, because it contains less lactose and more lactase, is usually well-tolerated by healing intestines and is a popular “healing food” for diarrhea. Many pediatricians recommend yogurt for children suffering from various forms of indigestion. Research shows that children recover faster from diarrhea when eating yogurt. It’s good to eat yogurt while taking antibiotics. The yogurt will minimize the effects of the antibiotic on the friendly bacteria in the intestines.

   NUTRITIP: A Chaser for Antibiotics

   Antibiotics kill not only harmful bacteria; they also kill the healthy ones in the intestines. The live bacterial cultures in yogurt can help replenish the intestines with helpful bacteria before the harmful ones take over. I usually “prescribe” a daily dose of yogurt while a person is taking antibiotics and for two weeks thereafter.

   A 1999 study reported in Pediatrics showed that lactobacillus organisms can reduce antibiotic-associated diarrhea.

   6. Yogurt can decrease yeast infections. Research has shown that eating eight ounces of yogurt that contains live and active cultures daily reduces the amount of yeast colonies in the vagina and decreases the incidence of vaginal yeast infections.

   7. Yogurt is a rich source of calcium. An 8-ounce serving of most yogurts provides 450 mg. of calcium, one-half of a child’s RDA and 30 to 40 percent of the adult RDA for calcium. Because the live-active cultures in yogurt increase the absorption of calcium, an 8-ounce serving of yogurt gets more calcium into the body than the same volume of milk can.

   8. Yogurt is an excellent source of protein. Plain yogurt contains around ten to fourteen grams of protein per eight ounces, which amounts to twenty percent of the daily protein requirement for most persons. In fact, eight ounces of yogurt that contains live and active cultures, contains 20 percent more protein than the same volume of milk (10 grams versus 8 grams). Besides being a rich source of proteins, the culturing of the milk proteins during fermentation makes these proteins easier to digest. For this reason, the proteins in yogurt are often called “predigested.”

   9. Yogurt can lower cholesterol. There are a few studies that have shown that yogurt can reduce the blood cholesterol. This may be because the live cultures in yogurt can assimilate the cholesterol or because yogurt binds bile acids, (which has also been shown to lower cholesterol), or both.

   10. Yogurt is a “grow food.” Two nutritional properties of yogurt may help children with intestinal absorption problems grow: the easier digestibility of the proteins and the fact that the lactic acid in yogurt increases the absorption of minerals. And even most picky-eaters will eat yogurt in dips and smoothies and as a topping.

   Perhaps we can take a health tip about yogurt cultures from cultures who consume a lot of yogurt, such as the Bulgarians who are noted for their longer lifespan and remain in good health well into old age.

   NUTRMYTH: All foods made with yogurt are created equal

   Not so. In fact, the yogurt used to coat nibble foods such as raisins, nuts, and fruit bits is often so highly sugared that you’re really eating more sugar than yogurt.

   HOW TO BUY THE HEALTHIEST YOGURT: 5 TIPS

   As when you purchase any food, read the label, both the “Nutritional Facts” panel and the list of ingredients. Look specifically at the following:

   1. The best nutritional deal is plain yogurt, which has only two ingredients: live cultures and milk (whole milk, low-fat, or skim). The longer the ingredients list, the more calories you get and the less yogurt nutrition. In some highly-sweetened containers of yogurt, you’re getting more calories in the sweetener than you are in the yogurt. Be sure to read the protein and sugar values on the nutrition panel. The higher the protein and the lower the sugar content, the more actual yogurt you’re getting in the container. You can make fun flavored yogurts with your kids that please their tastebuds and give you control over the contents of the yogurt. (See Recipes)

   BEST YOGURT
   Contains only live and active cultures and milk. Stonyfield’s Organic Yogurts.

   OKAY YOGURT
   Contains live and active cultures , milk, and some filler ingredients.

   DON’T-EVEN-BUY YOGURT
   It might as well be pudding if it says “heat treated” on the label, and it may contain added sugar and stabilizers - and more!

   2. The calcium content. The best yogurts provide 35 to 40 percent of the recommended dietary allowance for calcium in an 8-ounce container. Once the calcium gets below 30 percent of the DV, it’s a good bet that the container is filled with a lot of less-nutritious filler.

   3. Stonyfield’s Organic Yogurts - the one we recommend - has the highest level of live and active cultures besides containing inulin.

   Avoid yogurt that says “heat treated after culturing” on the label. This means that the yogurt was pasteurized after the healthful organisms were added, which dilutes the health benefits of the yogurt. Pasteurization deactivates the lactase and kills the live cultures, thereby obliterating two health benefits of yogurt. Heat- treating yogurt trades economic gain for nutritional loss. It prolongs the shelf life, but spoils its nutrition and health-food value. Lactose-intolerant persons who can tolerate yogurt containing live and active cultures may not be able to digest yogurt that has been heat treated. Yogurt-based salad dressings and yogurt-covered raisins, pretzels, and candy typically do not contain live and active cultures.

   The National Yogurt Association has been urging the FDA not to allow products that do not contain live and active cultures to be called “yogurt.”

   4. Yogurt terms to watch for. There’s a dizzying array of yogurts in the supermarket dairy aisle. Here’s a key to the different types.

   * Whole milk yogurt contains approximately 7 grams of milk fat per 8-ounce serving.
   * Lowfat yogurt contains between 1 and 4 grams (0.5% to 2 %) of milk fat per 8-ounce serving.
   * Nonfat yogurt contains less than 1/2 gram (less than 0.5%) of milk fat per 8-ounce serving.
   * In Swiss or custard-style yogurt, fruit and yogurt are mixed together. To insure firmness, a stabilizer, such as gelatin, may be added. This is also called “blended yogurt.” Swiss yogurt is fermented in vats and then transferred to cups. This process breaks the gel, so that artificial binders and stabilizers must be added.
   * Fruit-added or plain yogurt has a runnier consistency. The whey, the clear liquid at the top, should be stirred into the solids.
   * Yogurt also comes in liquid form, called “kefir,” which may contain added sweeteners such as corn syrup.
   * Heat-treated. Some yogurt manufacturers market “heat-treated yogurt” to prolong shelf life or decrease tartness and produce a more pudding-type texture. While perhaps more appealing to some, the heat treatment of the yogurt after the cultures have been added kills much of the health benefits of the yogurt.

   5. The benefits of plain yogurt. Ounce for ounce, plain yogurt is more nutritious than fruit-added preparations. Notice the differences on the labels:

   * Plain yogurt contains around one-half of the calories of the same amount of fruit-added yogurt.
   * Plain yogurt contains almost twice the amount of proteins.
   * Plain yogurt contains fewer fillers.
   * Plain yogurt contains more calcium.
   * Plain yogurt contains no added sugar.

   If plain yogurt doesn’t appeal to you, buy plain yogurt and flavor it with your favorite fruit. This way you control the sweeteners.

   5 WAYS TO USE YOGURT AS A NUTRITIOUS SUBSTITUTE

   Yogurt is one of the most versatile foods, especially for children who love dips and toppings. It can be used as a substitute for many high-fat foods. Here are some suggestions.

   1. Use yogurt in place of mayonnaise. Non- fat, plain yogurt contains less than ten percent of the calories, less than one percent of the fat, and around three percent of the cholesterol of an equal amount of regular mayonnaise. Combining equal amounts of low-calorie mayonnaise and lowfat yogurt works well for many dishes, including potato salad, coleslaw, pasta salad, tuna salad, dips, and appetizers.

   2. A favorite with toddlers. Yogurt makes a tasty and nutritious dip for toddlers, who love to dip their exploring fingers into new foods. It is also a favorite topping for toddler foods and a time-honored bait to entice toddlers to try new foods. (See Nibble Tray)

   3. Try whole plain yogurt as a healthy alternative to sour cream. It is much lower in calories, fat, and cholesterol. If you’re adding it to a sauce in place of sour cream, heat it over very low heat so it doesn’t curdle. After a while, switch to lowfat.

   4. Try yogurt in baking recipes. Plain yogurt can often be substituted for milk, buttermilk, or sour cream in recipes for waffles, pancakes, and muffins.

   5. Substitute yogurt for ice cream. Yogurt shakes and smoothies are a low-fat alternative to ice cream (See School-Ade recipe).

   NUTRIMYTH: Frozen yogurt is always a healthy substitute for regular yogurt.

   Not all frozen yogurts are created equal. Quality frozen yogurt will have at least 10 million live and active cultures (LAC) seal. The LAC seal signifies that the frozen yogurt has at least that amount of live and active cultures. While it has less live and active cultures than regular yogurt, frozen yogurt is still a good source of live and active cultures, calcium, and a delicious hot weather treat.

   6 HEALTH BENEFITS OF LACTOBACTERIA

   Healthy bacteria reside in everybody’s colon, and in return for food and a warm place to live these resident bacteria contribute to your health. One of the most intestinal-friendly resident bacteria is the family of lactobacteria, so-called because they thrive on lactose sugars. The resident germ you will read most about is L.acidophilus, which means “acid- loving,” because these organisms grow best in an acidic intestinal environment. Here are some healthy things these bacteria do for your body:

   1. Improve digestion. Lactobacteria, as the name implies, help digest the lactose in dairy products, preventing lactose overload, and lessening problems with lactose intolerance. Lactobacteria also help with the absorption of valuable nutrients and stimulate peristalsis, the movement of food through the intestines that leads to regular bowel movements.

   2. Manufacture vitamins. Like rich soil grows vitamin-rich foods, lactobacteria produce B-complex vitamins, along with vitamin K.

   3. Manufacture nutrients. Friendly bacteria help manufacture essential fatty acids called short chain fatty acids (SCFA). These are valuable nutrients for intestinal cells and also produce cancer-fighting substances.

   4. Boost immunity. Lactobacteria inhibit the growth of harmful bacteria and fungi, such as candida (yeast). They help keep the intestinal environment acidic and compete with harmful bacteria and the toxins they produce. They even produce hydrogen peroxide, which has a natural antibiotic effect.

   5. Protect against carcinogens. Lactobacteria bind potential carcinogens, preventing them from damaging cells. L.bulgaricus, the main lactobacillus used in yogurt, has anti-tumor properties. Specifically, lactobacteria bind heavy metals and bile acids, which are potential carcinogens. These bacteria inhibit the growth of nitrate-producing bacteria (nitrates can be a carcinogen). They also metabolize flavanoids, producing natural anti-tumor substances.

   6. Protect against cardiovascular disease. Lactobacteria help regulate cholesterol and tryglyceride levels in the blood.

   Be kind to the bugs in your bowels. They do good things for you.

   NUTRITIP: YOGURT FOR BREAKFAST

   A nutriperk in yogurt could theoretically improve school performance by perking up the brain. Yogurt is relatively high in the amino acid tyrosine (a neurostimulant) and low in the amino acid tryptophan (a neurosedative). Add yogurt to other brain foods, such as flax oil (for brain-building fatty acids) and soy foods (for protein and blood-sugar stabilization), and you have three synergistic foods that form the basic ingredients for our School-Ade recipe. I have personally felt the effects of this nutriperk by drinking a smoothie with these three basic ingredients each morning before I go to work. (See Brainy Breakfasts)
