Dairy Products

Dairy products or milk products are a type of food produced from or containing the milk of mammals. They are primarily produced from mammals such as cattle, water buffaloes, goats, sheep, camels and humans. Dairy products include food items such as yogurt, cheese and butter.

Powdered milk or dried milk is a manufactured dairy product made by evaporating milk to dryness. One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerated, due to its low moisture content.

Butter

Butter made from vegetable oil is called margarine. Margarine has the same physical properties as dairy butter, but its main base is not milk. This product is often prepared from a variety of vegetable oils such as corn, sunflower, soy and flax with some additives. This butter lacks the vitamins in cheese and is poor in minerals such as iron, zinc and copper.
Of course, this butter has the nutritional properties of vegetable oils, but due to thermal processes, its micronutrients are greatly reduced. For this reason, in order to make this product nutritionally similar to dairy butter, they enrich it by adding vitamins such as A and D, and by adding flavorings and colors, they create a special taste of butter in it.

Cheese

Cheese is a dairy product, derived from milk and produced in wide ranges of flavours, textures and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep.

Cream

Cream is a dairy product composed of the higher-fat layer skimmed from the top of milk before homogenization. In un-homogenized milk, the fat, which is less dense, eventually rises to the top. In the industrial production of cream, this process is accelerated by using centrifuges called separators.

Whey

Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacture of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey (also known as sour whey) is a byproduct brought out during the making of acid types of dairy products, such as cottage cheese or strained yogurt.
Whey proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulins, and proteose peptone.
