We all know that milk is rich in protein, fat, vitamins and minerals and other nutrients, of which milk protein contains amino acids necessary for the human body; milk fat is mostly short-chain and medium-chain fatty acids, which are easily absorbed by the human body; potassium, phosphorus, calcium and other minerals are reasonably proportioned and easy for the human body to absorb.
Such rich nutritional value makes milk an essential food for people's daily lives. When we buy in supermarkets, we occasionally see a less familiar term "restorative milk" or "restored milk", what exactly is restored milk? Is it real milk? Is it nutritious?
With these questions in mind, let's get to know the restorative milk together.
First of all, reconstituted milk is a real dairy product. In GB 25191, it is clear that the modulated milk is a liquid product made of no less than 80% raw cattle (sheep) milk or recombined milk as the main raw material, adding other raw materials, food additives or nutritional enhancers, and using appropriate sterilization or sterilization processes. The modulated milk produced entirely from milk powder should be marked "restored milk" or "restored milk" in the immediate vicinity of the product name.
According to the relevant requirements of the country, the restored milk generally adopts UHT (ultra-high temperature instantaneous) sterilization technology, that is, it is heated to at least 132 ° C in a continuous flow state, and all pathogenic bacteria, bacteria and spores are killed within 4 seconds.
In addition to high temperature sterilization, there is also a guarantee, that is, aseptic filling technology. Mainly using brick and pillow packaging, this packaging contains six layers of composite paper, which can isolate bacteria, air, sunlight, maintain the deliciousness of the product, so as to achieve the quality preservation effect.
Therefore, under this double guarantee, the restorative milk can be stored for a long time at room temperature without adding any preservatives, with a high safety factor and convenient storage, so that consumers in different geographical environments can enjoy high-quality dairy products.
So what is the nutritional value of this type of milk? We know that milk is rich in many nutrients, but there are four most important, namely protein, calcium, vitamin B2 and vitamin B12, although some ingredients will be inactive in the UHT process, but it does not reduce the nutrition in milk.
1. The protein in milk can still maintain its original characteristics after being treated by UHT technology, and the nutritional value is not affected;
2. The calcium in milk is relatively stable during the heating process and will not affect the body's absorption and utilization of it;
3. Milk after ultra-high temperature sterilization will indeed cause some heat-sensitive vitamins to be destroyed, but the degree of destruction is very low. In addition to vitamin B2 and vitamin B12, milk is lower in other vitamins needed by humans, and most vitamins are mainly obtained through vegetables and fruits.
It can be seen that restored milk is not only an important member of the milk family, but also has the same nutritional value as raw milk. As long as it is produced according to the specification and clearly marked, it can provide people with high-quality protein and calcium. The added nutritional elements can better meet the drinking of various specific groups of people, and can also make the taste more delicious, and everyone can buy with confidence.
