Food labels hide greasy

[China Packaging News] the health and safety of food has always been the focus of attention. Have you paid attention to whether the hygiene is up to standard, whether all indicators comply with relevant national regulations, and the information on food packaging? The production day can be stretched, tightened, zigzagged, torn, cut, 180 degree peel, 90 degree peel test period and shelf life. It seems to be a series of simple figures, which are also closely related to the food safety of citizens. What do the figures at the bottom of plastic bottles containing food represent

shelf life of food

in view of the above problems, experts suggest that: shelf life refers to the period to maintain food quality under the conditions specified on the label. To be precise, the shelf life of food is the best eating period of food. Within the period indicated on the food label, all indicators of food should comply with the provisions of product labeling. Beyond this period, some sensory characteristics of food may change, and the content of some nutrients may be reduced, failing to meet the requirements of product standards. However, at this time, the health indicators still meet the standard and can be eaten for a certain period of time

food labels hide a variety of information

shelf life refers to the final date when the food can be eaten under the conditions specified on the label. Beyond this period, the product quality may change, so the food can no longer be sold. The shelf life of food is the final consumption period stored under the conditions specified on the food label. Beyond the eating period, the sensory characteristics, physical and chemical indicators and health indicators of food may no longer meet the requirements of product standards, or even become moldy, deteriorated and inedible

basic methods for identifying food labels

check whether the contents of the labels are complete. The contents that must be marked on the food label include: food name, ingredient list, net content and drained matter, solid form. However, the market sales of wood plastic composite new materials in China is less than 20billion yuan. The content, name and address of the manufacturer, production date or packaging date and shelf life, and product standard number

check whether there is QS flag. Rice, flour, oil, soy sauce, vinegar, meat products, dairy products, beverages, condiments (sugar, monosodium glutamate), instant noodles, biscuits, cans, frozen drinks, quick-frozen rice noodles and puffed food must obtain QS food safety certification before production, so when choosing food, you should recognize QS mark

check whether the label content is clear and complete. All contents of food labels should be clear and eye-catching, easy for consumers to identify and read when purchasing food, and should not become blurred or even fall off in the circulation link, nor should they be separated from the packaging container

in addition, check whether the label content is scientific and standardized, and whether it really makes the pointer return to zero and change greatly. The language, words, graphics and symbols on the food label must be accurate and scientific, and comply with the requirements of the general principles for the labeling of prepackaged food. At the same time, all the contents of the label must not describe or introduce the food in a wrong, misleading or deceptive way

how to correctly identify food labels

in addition to marking the normal date, the shelf life and storage period of food can be marked in many ways. Consumers need to correctly understand the meaning of specific marking, for example, it is best to eat or drink before x day, or it is best to eat or drink before x day, which generally indicates the shelf life of the product, and before x day, which generally indicates the shelf life of the product

in addition, some foods can also be unmarked with shelf life and shelf life. For example, when we buy some commodities, such as Baijiu, salt, sugar and so on, we can find that most of the packages are not marked with shelf life or shelf life. According to the provisions of the general standard for food labeling, the shelf life and shelf life of foods with a shelf life or shelf life of more than 18 months have been clearly specified in national standards or industrial standards. If the shelf life is less than 7 days, consumers themselves understand that it is instant consumption, such as yogurt, cream, bread, etc., but the law does not prohibit manufacturers from voluntarily marking the shelf life or shelf life

due to the particularity of food, consumers should pay attention to the shelf life when purchasing food, and pay attention to the difference between shelf life and shelf life to avoid confusion. In addition, except for products that may not be marked by law, other products without a shelf life should be rejected to ensure their own rights and interests

mastering the correct identification method of food labels and labels can not only enable us to understand the quality characteristics, safety characteristics, eating and drinking methods of the purchased food, but also enable us to identify fake and inferior food by checking the labels. If we find and prove that the labels are inconsistent with the actual quality, we can complain in accordance with the law and obtain compensation

Special attention should be paid to some microwave oven lunch boxes. The box body is indeed marked with 5, but the box cover is a plastic product marked with 1. Because it cannot withstand high temperature, it cannot be put into the microwave oven together with the box body.

If the box cover is a plastic product such as tensile test, impact test, compression test, zigzag test, etc., remove the box cover before putting into the microwave oven

some bowled instant noodles boxes and fast food boxes are marked with 6. Although the plastic made of this material is heat-resistant and cold resistant, it cannot be put into the microwave oven to avoid releasing chemicals due to high temperature. Moreover, this kind of plastic cannot be used to contain strong acids (such as orange juice) and strong alkaline substances, because it will decompose polystyrene, which is bad for human body, and is easy to cause cancer.
