What’s in all kinds of milk?
DELICIOUS
Milk has high nutritional value and is convenient to eat. It is an ideal natural food.
The milk protein in milk is a high-quality protein, and its essential amino acid ratio meets the needs of the human body; the calcium in milk is the most easily absorbed source of calcium in the diet; milk is also an important source of nutrients such as phosphorus and vitamins necessary for the human body. .
However, there are too many products on the market that look like milk, such as fresh milk, pure milk, high calcium milk , breakfast milk... numerous brands, flavors, styles, different production processes, etc., allowing consumers to choose. Really strenuous. What are the ingredients in these various milks? Let’s find out!
01 The difference between fresh milk and pure milk
Fresh milk and pure milk are liquid milk products made from raw milk using appropriate sterilization or sterilization processes, and the milk content is 100%. As you can see from the ingredient list on the product label, fresh milk and pure milk only have raw milk as an ingredient. This milk is good for good health and should be the dairy product of choice for consumers.
According to different sterilization methods, milk with 100% milk content can be divided into pasteurized milk and sterilized milk. The best way to distinguish between these two products is to look at the food name, storage conditions and shelf life.
Pasteurized milk is the "fresh milk" we see in the refrigerated sales area of supermarkets. The product must comply with the regulations of GB 19645-2010 " National Food Safety Standard Pasteurized Milk ". Because the pasteurization temperature is lower than 100°C, the sterilization process only kills the pathogenic bacteria, and some microorganisms are still retained in the product, so its transportation, storage and sales temperatures must be controlled at 2°C to 6°C, and generally It can only be kept for about 7 days.
Sterilized milk is "pure milk" sold at room temperature. The product must comply with the regulations of GB 25190-2010 " National Food Safety Standard Sterilized Milk ". Sterilized milk is instantly sterilized at high temperatures above 100°C, which eliminates all microorganisms in the milk. Therefore, there are no low-temperature requirements for transportation, storage and sales, and the shelf life is relatively long, generally more than half a year.
From a nutritional point of view, there is basically no difference between fresh milk and pure milk in terms of protein and fat. It is just that the sterilization temperature of fresh milk is lower than that of pure milk. Therefore, under the same milk source, fresh milk has the same taste as There is a slight advantage in trace elements. However, if you need to take milk products out and it is inconvenient to store them at low temperatures, such as if you want to drink them during outings or long-distance travel, it is appropriate to choose pure milk that is more convenient to transport and store.
02 What is the blend of modified milk?
Modulated milk is based on raw milk. According to the characteristics of the target population, the taste and some nutrients have been appropriately adjusted.
For example, this breakfast milk is added with cereals and fruit and vegetable powder .
This high-calcium milk has added milk mineral salts ( milk calcium ) and vitamin D.
Modulated milk products must comply with the provisions of GB 25191-2010 " National Food Safety Standard Modulated Milk ", which requires the milk content to be no less than 80%. Other added ingredients are usually used to enhance nutrition or improve taste to meet the needs of different groups of people. Diverse needs.
03 The essence of milk-containing drinks is drinks
Milk-containing drinks are drinks rather than milk. Milk-containing beverages also have their own exclusive standard GB/T 21732-2008 "Milk-containing beverages", but this is not a mandatory national food safety standard.
Milk-containing beverages have a low milk content, so the first item on the ingredient list is usually "water", followed by dairy ingredients such as raw milk and milk powder. In addition, the product type of food must reflect the true attributes of the product and be marked in a prominent position on the food label. So if you look carefully, you will definitely find special nouns on the label that represent the true attributes of the food.
Milk-containing beverages come in a variety of varieties and have outstanding tastes. There is no problem in drinking them as ordinary beverages.However, due to the low milk content, milk-containing drinks are far inferior to other dairy products in terms of protein and other nutrients, so even if they are consumed in large quantities, they cannot replace nutritious milk.
04 How to distinguish between prepared milk and milk-containing drinks
Faced with the dazzling array of banana milk , banana milk drinks, banana-flavored milk drinks and a series of "milk" products on the market, you can distinguish which ones are prepared milk and milk drinks from the product names. What are milk drinks?
Some people apply the difference between fruit drinks and fruit-flavored drinks, taking it for granted that products with "taste" and "beverage" in their names must be low-end products. However, this trick may not be effective when applied to milk.
This product is called banana milk. The first one on the ingredient list is raw milk, which is a prepared milk.
This product is called Banana Milk Drink. The first item on the ingredient list is water, which is a milk-containing drink.
This product is called banana-flavored milk drink. It has both "flavor" and "drink", but the first one on its ingredient list is milk, which is a modified milk.
It can be seen from this that the distinction between prepared milk and milk-containing beverages cannot be based on the product name, but on the ingredient list and the product type that reflects the true attributes of the food.
05 What are nutrient-dense dairy products?
Knowing so much knowledge about milk products, how can consumers buy real milk that is rich in nutrients?
First of all, you can choose fresh milk and pure milk with raw milk as the only raw material. For other milk products, be sure to read the ingredient list clearly. The milk content of prepared milk should not be less than 80%, and the first ingredient list with "water" is often a milk-containing drink with low nutritional value.
Another way to identify is to look at the protein content in the nutrition facts table. The protein content of sterilized milk and pasteurized milk is required to be above 2.9g/100g, the protein content of prepared milk is required to be above 2.3g/100g, and the protein content of milk drinks only needs to be above 1.0g/100g. The higher the protein content, the better the nutritional value, and consumers can make choices based on this indicator.
Through the above methods, consumers can quickly identify members of the milk family and their "distant relatives" and choose the appropriate product according to their needs.
