It contains not less than 65 percent milkfat not less than 165 percent milk solids-not-fat and not less than 23 percent by weight of total milk solids. Capra and this seemed like a great thing to recommend for thickening goat milk yogurt.
This is the technique weve been using to make our yogurt and have been very happy with the thickness.
What are milk solids in yogurt. Yogurt contains not less than 325 percent milkfat and 825 percent solids-not-fat. Evaporated Milk - is made by removing about 60 percent of milks water. It contains not less than 65 percent milkfat not less than 165 percent milk solids-not-fat and not less than 23 percent by weight of total milk solids.
Yogurt a cultured dairy product is milk fermented by lactic acid bacteria mainly Lactobacillus delbrueckii ssp. Bulgaricus and Streptococcus thermophilus. Milk solids are small dairy-derived food particles that contain lactose caseins whey proteins and trace minerals also called ash content of the products from which they were derived.
Milk solids are added to many types of foods to create a uniform texture and sometimes enhance taste. These solids are derived from milk cheeses yogurt and other lactose-containing food items and they are further. We noted in the proposed rule that the yogurt standard currently requires that the basic ingredients of yogurt be either milk or certain milk-derived ingredients and that yogurt must contain a specified minimum amount of milk solids not fat 74 FR 2443 at 2453.
We did not propose to require a minimum amount of dairy ingredients in yogurt because the existing yogurt standard 131200a b and c. The thickness of the yogurt results from the coagulated proteins determined by the fat content of the milk the yogurt starter and amount of milk solids protein. Adding nonfat milk powder milk solids to cold milk before heating will result in a firmer yogurt.
However adding nonfat milk powder to heated milk will cause some proteins to coagulate and form strings. Yogurt is a fermented milk product that contains the characteristic bacterial cultures Lactobacillus bulgaricus and Streptococcus thermophilus. All yogurt must contain at least 825 solids not fat.
Full fat yogurt must contain not less than 325 milk fat lowfat yogurt not more than 2. Must contain a minimum of 825 solids not fat. Full fat yogurt must contain not less than 325 milk fat while low fat yogurt can contain 20 milk fat maximum and nonfat yogurt must be less than 05 milk fat.
21 CFR sections 1312 also allow for additions of Vitamins Optional Dairy Ingredients Nutritive. As the milk is heated the fat in the milk changes its chemical structure making it easier to react with the whey protein in the milk. This improves the texture of the milk by making it creamier and thickens the yogurt further as the whey protein is included in the solids found in the milk.
One of the ways you can get a better firmness in yogurt is to add powdered milk. This increases the volume of milk solids so the resulting yogurt is thicker. A couple of years ago we discovered a great source of organic dry goat milk from Mt.

Greek yogurt is especially helpful for babies starting solids because it clings well to spoons and fingers. Otherwise specific types of yogurt have different tastes and nutritional strengths so have fun experimenting. In general goat yogurt Greek yogurt and sheep milk yogurt varieties tend to have more protein than cow milk yogurt.
Where regular yogurt is almost pourable Greek yogurt is nearly solidyou can practically stick a spoon upright in it. And thats because Greek yogurt is strained while regular yogurt is not. Codex regulations for yogurt indicate that the minimum milk protein content is 27 except for concentrated yogurt where the minimum protein content is 56 after concentration and the maximum fat content is 15 Codex 2008.
The total solids content of milk can be increased by concentration processes such as evaporation under vacuum and membrane processing ie reverse osmosis and ultrafiltration. During this step try holding the milk at 200F for 20 minutes or longer. This allows some of the moisture in the milk to evaporate and concentrates the solids.
This is the technique weve been using to make our yogurt and have been very happy with the thickness. Let the Yogurt Sit The longer the yogurt has to set the thicker it will. The process releases water that when frozen separates from the milk solids.
Thawed yogurt doesnt make the smoothest sauces so if youre at all concerned about texture save your thawed. Yogurt is a semi-solid sourish food prepared through the fermentation of milk by adding lactic acid bacteria normally Lactobacillus bulgarius and Streptococcus thermophilius. Lactic acid produced during the fer-mentation preserves the milk from spoilage and patho-gen growth.
Yogurt was developed and consumed in the Middle East as early as 2000 BC. All ingredients used are safe and suitable. Lowfat yogurt before the addition of bulky flavors contains not less than 05 percent nor more than 2 percent milkfat and not less than 825 percent.
