Now theme of natural products is very popular, particular attention is paid to milk and its derivatives. We asked our expert, Olga Sokolova, junior Central Laboratory of Microbiology of the GNU VNIMI Agricultural tell how to distinguish this milk from dosed with antibiotics, preservatives and whether you want it to boil and when to give children.
It is true that milk "straight from the cow" is not always possible to include an environmentally friendly product? Buying such milk, I want some safeguards. But, in my personal opinion, they seem to have ...
Indeed, recent ecological products are very popular. In order to distinguish them some store shelves, give light weight banners and sell them for insane prices. From a technological point of view ekomoloko and dairy products did not differ from the ordinary.
As to the question - how to check? No way! Rely on the manufacturer. And again - antibiotics in milk and dairy products are not allowed."Environmentally friendly" products is entirely on the conscience of the manufacturer.
It is said that fresh milk - the most useful. But there is also the view that the entire two hours in it begin to become more active bacteria. How to keep fresh milk in all the useful properties? Put in a cold place? And how do you know that it is properly stored, if, say, the milk you order via the Internet from a private farmer?
In fresh milk from the vydoyki present a natural enzyme lysozyme, which prevents the processes of damage and inhibits the development of microflora. But, after about 2 hours after vydoyki, lysozyme is inactivated, and the milk is rapidly starting to breed bacteria. Therefore, fresh milk is really only useful for the first 2 hours.
If milk is ordered on the internet, or just buy from someone with hands - there are no guarantees. Just after buying the milk should be boiled immediately.
If you absolutely do not drink boiled milk - it must be heated to nearly 100 degrees (well, if you have a thermometer) on and off. Then get pasteurized milk.
If we are talking about the boiling of milk ... It is believed that milk is basically better to drink boiled - is not it?
I think - no. This opinion has gone from our grandparents. Then boiling was considered the only true way to protect the milk. Milk is better to drink or simply warmed or cold. As you wish.
When boiling is denaturation of proteins, membranes rupture of fat (in milk fat in the shells, as if the balls), vitamins, break down, break down some of the amino acids .
Is it true that milk contains a lot of radionuclides?
In the milk does not contain radionuclides, in fact - the milk has radioprotective properties. At the Institute of the dairy industry there is a specialized laboratory, which deals with this issue. Development lab were very helpful after the disaster at Chernobyl.
Is it true that milk is not compatible with other products and should be used separately? For example, if bad enough popular in Russian cooking traditions of a combination of potatoes and milk?
This question is more appropriate to ask a dietitian. And I think that the compatibility and the irreconcilability of products for every human individual. In terms of biotechnology, the incompatibility with the same potatoes do not.
Children and milk. Your recommendations?
It depends on what age children. I believe that children up to 8 months of raw milk (any - cow, goat, sterilized, pasteurized) should not be given. We can only cook with milk porridge. In kindergarten and school age, I think milk is a necessary element of the diet.
When can I start giving your child yogurt, and what is this?
In my opinion, no fillers, yogurt and sugar can give a child with a 6.5-7 months. Subject to the introduction of complementary foods from 6 months. With the introduction of complementary foods earlier - and yogurt can be used.
Do I need to exclude adults with milk from their diet? Is it true that it is only useful for children and an adult it simply does not assimilate?
With age in humans decreases the amount of enzymes that break down milk sugar. Referred to as a disease of lactase deficiency. Lactase - an enzyme that breaks down milk sugar - lactose. So often adults can not drink milk - feel discomfort, nausea, and so on.
But that does not mean that we should give up dairy products altogether.The fact that lactic acid bacteria break down the milk sugar. Therefore, milk products, cottage cheese, and some people might, even with lactase deficiency.
There is a myth that cow's milk allergy manifested more than a goat. Is this true and why?
This, alas, not a myth. This is due to the different protein composition of milk of various animals. It often causes a cow's milk allergy than milk of goats, sheep, buffaloes and horses.
Now, many mothers prefer to make dairy products on their own, at home. This is due to the fact that in the "shop" yogurt add a lot of dyes and preservatives, use powdered milk. Are there any pitfalls in the use of home yogurtnits?
The idea of making yogurt at home is beautiful. It's good practice. But, nevertheless, it is the misuse of yogurtnits associated almost half of poisonings, especially in children.
Only two common mistakes. The first - fermenting yoghurt at home purchased from dairy products. Second - put in leavens milk additives (sugar, vanilla, honey, jam, berries, cocoa, and so on)
