The concept of dairy products is used in our language to designate those products made from milk or derived from it, such as cheese, yogurt, butter, milk cream, to name the most consumed. For example, it is milk, the nutritive secretion that comes from the cow's mammary glands, the main element used to make dairy products.
Products derived from milk are normally obtained thanks to the milk fermentation and processing once obtained.
Both milk and products derived from it are considered highly perishable and for this fact it is recommended to comply with the maintenance of the Cold chain once they are produced and until they reach the hands of consumers, who must also comply with this obligation to preserve them.
They should always be kept refrigerated, that is, in the refrigerator and also strictly respect the expiration dates that are inscribed on their containers. Also due to this issue is that the packaging of dairy products have a special design to protect the product in this regard.
One of the essential components of milk is lactose, a type of disaccharide present in a percentage ranging from 4 to 5% and that is composed of glucose and galactose, that is to say, it is the milk sugar. For humans to be able to absorb lactose correctly, it is necessary that they have an enzyme called lactase, which occurs in the small intestine. Now, if the human body has little or no lactase, lactose cannot be assimilated and this can generate in the person what is called lactose intolerance which is transferred to dairy.
Since the middle of the last century, dairy products have experienced hyper-massive consumption and this has obviously led the production industry to develop large-scale technologies in order to meet the enormous demand in a timely manner. However, the consumption of dairy is not something of today but it is really millennial, approximately dating from about eight thousand five hundred years ago. The itinerant tribes of the period NeolithicOnce they managed to domesticate animals such as goats and sheep, they began to use their products, including milk, and other derived products appeared from it.
Although it is a reality that most of the dairy products that we consume today come from cows, it should be noted that milk is also consumed from other mammals in addition to the cow, such as: goat, sheep, buffalo, camel and mare, although of course, in a smaller quantity.
