How to choose and identify food? How to use food labels to make food purchases

1. When purchasing food, it is necessary to choose the one with the QS logo, which is the sign that the enterprise obtains the production license.

2. When choosing food, you should carefully check the food packaging. Observe whether the packaging is damaged or leaking, and whether the font is printed properly, so as to avoid buying contaminated or counterfeit food.

3. It is necessary to see the production date and shelf life indicated on the food packaging to ensure that the food is within the shelf life.

4. The name of the food must use the name specified in the national standard and industry standard; Consumers should also pay attention not to be confused by some new names, novel names or trademarked names used by enterprises, and should still pay attention to the names of the real attributes of the food. Consumers should also be aware of the presence of food additives in food, which must be clearly stated on the label if they are used.

According to the General Standard for Food Labeling (GB7718 87) approved and implemented by the State Bureau of Technical Supervision, you can use food labels to guide you in purchasing food. Distinguish the connotation and quality characteristics of food from the name of the food indicated on the food label. The name of the food that meets the provisions of the "Standard" indicates the true attributes of the food, and when purchasing food, it is necessary to pay attention to the name marked on the label.

Identify the intrinsic quality and special utility of food products from the ingredient list or ingredient list. Food made of more than two kinds of raw materials has an ingredient list, and is arranged in order according to the number of ingredients, if the ingredients are not marked, the general content is less than 25%. Special foods, which have ingredients that distinguish them from similar foods on the label.

For example, children's multivitamin biscuits should have a table of various vitamin content. Identify food products by net or solids content.

Food plus number, then add a lot of things product, parent number, if what is needed? Just remember the number.

First, never buy pre-packaged food that has exceeded its shelf life.

Second, it is necessary to pay attention to whether the "name" of the food is consistent with its "ingredients". For example, the name "orange juice" is written on the packaging, but the ingredient list says water and food flavor, indicating that the manufacturer uses orange flavor to make a fruity water drink to pass off as a nutritious juice.

The third is to have a correct understanding of similar food names. For example, peanut oil is blended with peanut oil, one is pure peanut oil, and the other is made by mixing peanut oil and one or more other vegetable oils; Milk and milk drinks, lotus paste mooncakes and lotus paste mooncakes are foods with similar or similar names but different attributes.

Fourth, we should pay attention to the net content. The so-called net content refers to the content of the edible part except the packaging, and some food packaging is large and beautiful, but the content is very small.

Fifth, pay attention to the calories and nutrients of the food. At present, it has been recommended or required internationally to indicate the nutrients in such foods, such as proteins, fats, carbohydrates, vitamins, calcium, iron, phosphorus, magnesium, zinc and copper, etc., on the packaging of food, and must be tested and confirmed by relevant departments. China has also begun to implement the labeling of food nutrients, and consumers can choose according to their own needs or those who eat them.

1. When buying food, pay attention to whether the food packaging has the manufacturer, production date, whether the shelf life has passed, whether the food raw materials and nutrients are marked, whether there is QS logo, and you cannot buy three no products.

2. Open the food package and check whether the food has its due sensory properties. Do not eat spoilage, rancidity, imitation jujube mildew, insects, filth, unclean, mixed with foreign matter Iwano or other abnormal sensory properties of food, if protein food sticky, fatty food has a howling smell, carbohydrates have the smell of fermentation or drinks have abnormal sediment, etc.

3. Do not buy lunch boxes or food from unlicensed vendors to reduce the risk of food poisoning.

4. Pay attention to hunger and personal hygiene, wash hands before and after meals, wash and disinfect your own tableware, do not use unclean containers to hold food, and do not litter to prevent mosquitoes and flies from breeding.
