Milk is one of the increasingly important foods in our lives, but when housewives stand in front of the dazzling milk counter, how should they choose for nutrition and freshness?
Pure fresh milk is a source of health for different groups of people. It not only replenishes nutrients and calcium, but also moistens our taste buds with its unique fresh flavor. You may have never paid attention to some of the text on fresh milk packaging, but in fact, these words are of vital importance to our choices! These words are marked on the outer packaging of fresh milk, have you noticed them? Do you know what they mean? I. Milk Dictionary Raw Milk
In many developed countries, unpasteurized raw milk is the most popular among consumers, but it is also the most expensive. Freshly milked milk contains antibacterial active substances such as lysozyme, which can be preserved for 24 to 36 hours at 4°C. This milk does not need to be heated, it is not only rich in nutrition, but also retains some trace physiologically active components in milk, which is very beneficial for children's growth. Unfortunately, it is not yet available in the Beijing market! Pasteurized Milk
Milk with a short shelf life is mostly "homogenized" milk pasteurized by the pasteurization method. This method of sterilization can achieve more ideal preservation of the nutritional components in milk and is one of the most advanced milk sterilization methods in the world today. The so-called "homogenization" refers to a new process in milk processing, which is to crush the fat globules in the milk so that the fat is fully dissolved into the protein, thereby preventing fat adhesion and coagulation, and making it easier for the human body to absorb. The shelf life is generally within 48 hours, and their nutritional value is not much different from fresh milk. The loss of B vitamins is only about 10%, but some physiologically active substances may be inactivated. Is UHT milk nutritious? Sterilized Milk
Many manufacturers produce long-shelf-life "brick pack" milk to meet the needs of office workers. The long-shelf-life brick pack milk has been fully sterilized during the processing process, and the beneficial bacteria for the human body are basically "caught in one net", and the nutritional components of the milk are thus destroyed. The packaging of this milk is very similar to fresh milk, and the shelf life is mostly 30 days or longer, and some sterilized milk has a shelf life of more than 6 months. Sterilized milk generally has a richer flavor, but the nutrients are somewhat lost, with a loss of 20% to 30% of B vitamins. Antibiotic-free Milk
This term has been recognized by most people, but it does not appear on the outer packaging of milk, because it is one of the indicators for milk leaving the factory. Generally, milk from well-known manufacturers should meet this standard. Antibiotic-free milk refers to milk produced from raw materials that do not contain antibiotics. "Anti" refers to the various antibiotics used to treat sick cows, such as penicillin, streptomycin, etc. Cows are prone to mastitis during seasonal changes every year, and mechanical milking also makes cows more prone to mastitis than manual milking. Injecting antibiotics directly into the cow's udder can help the cow recover quickly. After antibiotic treatment, the milk produced within a certain period of time will contain residual antibiotics, and this milk cannot be used as raw material for processing and producing edible milk. II. 5 Misconceptions About Milk 1. The more fragrant the milk, the better
Milk has a milky fragrance only when heated, and it is difficult to smell the fragrance when cold. 2. The thicker the milk, the better
The thickness of milk can directly reflect the quality of the milk. If you think the thicker the milk the better, you can add thickeners, stabilizers or milk powder, but then it is not pure fresh milk. Bulk milk is good Because we don't understand the health status of the cows, experts recommend not drinking bulk milk. 3. Milk is better when heated
If you want to drink hot milk, you can soak it in hot water (no need to use boiling water). Milk should not be heated at high temperature for a long time, nor should it be frozen. 4. Drinking more milk will make you fat
If a person drinks 500 ml of milk per day, it can provide about 140 kcal of heat for the human body, while a normal person needs about 3000 kcal of heat, so drinking milk will not cause weight gain. 5. Milk can be used as drinking water
Water is very important for the human body. To maintain balance in the body, it must be supplemented from the diet. Beverages and milk contain a lot of water, but they are both hypertonic drinks. Drinking too much, especially when sweating and losing too much water, can easily lead to dehydration. Therefore, milk cannot be used as drinking water.
