As the saying goes, "Disease enters through the mouth." The quality of food is directly related to human health. Eating expired or spoiled food by mistake can make people sick and even endanger their lives. Therefore, when purchasing food, you must be able to identify fake and substandard food to prevent being deceived and to ensure safety. In layman's terms, the so-called "fake" means that the food is fake and the food contains inedible raw materials; the so-called "bad" means that the food is inferior and does not meet the usual legal or industry standards. So how to identify fake and inferior food?

1. Mainly check trademarks, packaging, etc.

1. Recognize the registered trademark logo clearly. Famous and high-quality foods have registered trademarks on their outer packaging. Some fake and inferior foods have fake trademarks, and some have no trademarks. The fake ones are fake after all. There are always differences when comparing fake trademarks with real trademarks. If there is no trademark, it is easier to identify fake and inferior food.

2. Pay attention to the markings on the outer packaging. Famous and high-quality products are printed with the food name, production batch number, factory name, factory address, product certificate, and high-quality product mark on the outer packaging. For limited-time use foods, the factory date, expiration time, etc. are also marked. The above-mentioned marks on counterfeit food are incomplete or used indiscriminately. Some have no factory name or use fake names, and some only have "Made in China" printed on them. Famous brand foods should also be checked for unique markings. Most famous and high-quality foods have unique markings.

3. Pay attention to packaging. Most famous and high-quality products have clear decorative patterns, lifelike images, bright and harmonious colors, fine workmanship, and good quality packaging materials. Fake and inferior products have dull and outdated colors, fuzzy patterns, and shoddy packaging.

4. Pay attention to the manufacturers. There are many manufacturers of famous and high-quality products whose food names are named after places, but there is only one manufacturer of authentic traditional famous and high-quality products. Therefore, it is necessary to identify the factory name to prevent counterfeiting.

5. Select the sales unit. Some high-end famous foods are only sold in specific stores; foods with a large gap between supply and demand, such as brand-name goods, only have a few arranged "special products" and cannot be put on the market in large quantities. Therefore, when purchasing such foods in the market, be careful of counterfeit products.

6. Check the sealing area of ??food packaging carefully. Generally speaking, the sealing area of ??famous and high-quality food packaging is relatively flat, while the sealing area of ??fake and shoddy food packaging is uneven, wrinkled and sticky.

2. Check the food itself

Since packaging, trademarks, etc. are often imitated and misappropriated by unscrupulous traders, checking the quality of the food itself is an important step in identifying fake and inferior food. "Look", observe "color", smell "taste", touch "body" and other methods.

Compare the same kind of food to check whether there are any changes or abnormalities in the whole. For example, when buying a drink, you can ask the salesperson for a few more bottles. After shaking each bottle, compare the bottles to see if the body fluids are clear and turbid, the color is bright and dark, and whether there are turbidities, debris, etc. All liquid foods can be inspected and identified in this way. When buying boxed food, open a few more boxes to compare. There are usually open samples on display on the counter. Compare the color, smell, and softness and hardness of each box to see if they are the same. For food in plastic bags, try your best. Compare the bags to the bags. After comparison, if it is found that there are some abnormalities in the whole, it means that the quality of the food is inconsistent or has begun to deteriorate, so it is best not to buy it.

In addition, please note that you must not buy treatment products. Why should the price of such good food be reduced? Anyone who handles it has either expired or has deteriorated due to poor storage. Therefore, this food is the most dangerous.

There are many types of food, and the forms of counterfeit and substandard food are even more bizarre. The methods and ways to identify counterfeit and substandard food also vary widely. I believe that students will use these identification methods, the scientific knowledge they have learned, and the experience they have accumulated in life to more effectively identify fake and substandard food.
