When buying products in stores or from farmers, you always want to be confident in the honesty of the seller and the naturalness of the purchased goods. Milk is a drink that brings great benefits to the human body in a pure, not diluted form, and its quality directly depends on the health of its living producer.
What percentage of the water is in the milk?
Milk is a liquid, therefore its main component is water. Its content is as much as 87.5%. The remaining nutrients are in it in such proportions: 
| Substance | % |
| Fat | 3,8 |
| Milk sugar | 4,7 |
| Protein | 3,3 |
| Calcium, magnesium, phosphorus, vitamins | 0,7 |
Important! Buying milk is best from the same seller. Each farmer feeds his animals in different ways, which directly affects the quality of the product. Its taste may differ significantly from different cows.
Why does a cow have liquid milk like water
There are several factors that directly affect the fat content of the drink:
- Health. One of the first indicators of a cow’s health is fatness and the quality of its milk. So, if it is too watery, it may indicate tuberculosis. The final diagnosis can only be made by a doctor, after examining all the symptoms and making certain tests.
- Weather. In the hot season, the milk becomes thinner. In order to make it fatter, the cow needs a cool enough place for grazing with plenty of shade, where she can hide from the scorching sun.
Did you know? For cows communication with the person is of great importance. It is proved that farmers who are gentle and kind to their pets, get a better product than the indifferent, and the more cruel owners.
- Nutrition. Lack of fat content can cause a lack of oats in the diet of the animal. This cereal due to its nutritional value most affects fat. You can also feed more with hay, straw and fresh grass.
- Heredity. Also, the fat content depends on the breed of the animal. The more milk a cow gives, the thinner it becomes over time.
How to determine milk diluted with water
Unscrupulous trademarks and ordinary sellers have got the hand to dilute the drink with water, but there are several ways that will easily expose such scammers.
Alcohol
The easiest way to determine not only the fact of the content of excess water in the product, but its exact amount is the use of alcohol. For this experiment, you will need alcohol 76% or higher.
- Take 1 teaspoon of milk and 2 teaspoons of alcohol.
- Mixing and shaking.
- Pour in a saucer, take a timer and note the time that passes before the flakes appear in the mixture. Pure milk rolls up quickly, so within 5 seconds you can already watch the folding. If the process is delayed for minutes - it is definitely diluted.
Important! Vodka for this method is not suitable, because it has too much water.
The amount of excess water can be determined by the time it took to coagulate:
- minute - 20% of water is present;
- 20 minutes - 40%;
- 40 minutes - 50%.
Warm water
To determine the integrity of sellers, it is necessary to pour a thin stream of milk into a glass of warm water. The fat product will be denser than water and will remain at the top with a thin edge. The diluted white liquid is mixed with the rest of the water, and you get a glass with an off-white mixture.

Iodine
Also, some manufacturers and sellers add starch to the drink for the appearance of its greater fat content (density). However, this deception is easy to expose using ordinary iodine. 
To do this, you need to drop a couple of drops of iodine into a small amount of whole product (not removed) and look at the color: blue will indicate the presence of starch, and yellow-orange will indicate the absence of a useless thickener.
Did you know? The tradition to drink milk before bedtime is due to the fact that it has an excellent sedative effect and guarantees no insomnia at night.So, a healthy animal with proper conditions of maintenance will provide tasty and healthy milk. But modern sellers have found dozens of ways to visually improve it, forgetting about the buyers in favor of their own advantage. Fortunately, there are equally simple methods for identifying such fraud, which any buyer who doubts the quality of a drink can use.
