[Chinese Packaging Network News] In the market, different foods have different packaging methods, and as consumers want to buy safe and safe food, what should pay attention to it? Different packaged foods need different attention when they are purchased. Today, teach you how to choose different packaged foods.
The principle of buying food
Do not buy food from unknown sources. If the label on the package is not clear, or it is completely foreign language, or if the food is not sold in a fixed place, be careful. The price of such food may be relatively cheap, but it is not guaranteed. Is it safe to eat?
Select vegetable oil. Use as little animal oil as possible because animal oil contains a lot of cholesterol, which is detrimental to the health of the heart and blood vessels. When shopping, special attention should be paid to whether there is production company information and production license QS label on the packaging. If there is such information, it is the edible oil with quality guarantee.
Recognize fresh meat. When buying meat, notice that the flesh is pink, fresh when touched; if it is fish, observe it again, if the eyes are transparent, bright red and fresh without fish smell. Of course, you should try to purchase meat of guaranteed quality at a large supermarket or shopping mall.
The food logo must be complete. For fresh packaged foods purchased in supermarkets, in addition to price, we must also carefully look at whether the information on the packaging is complete and detailed, such as: net food content, name, food additives, name of the manufacturer, address, contact information, shelf life, and origin And production date.
Pay attention to the preservation temperature of frozen foods. When buying frozen foods, it should be chilled and stored below -18°C, and it is hard when it is picked up, not wet and soft. The food that has been a bit thawed may have already begun to decline in quality.
Buy canned food and note good canning. When choosing canned foods, you must choose a good and complete can body, no unevenness and rust; in addition, special attention should be paid to the can body QS production license signs and numbers in order to be able to buy at ease.
Learn how to pick fresh eggs. Fresh eggs have a rough matt shell and they don't transmit light when they are lighted. When shaking eggs, there is no noticeable internal shaking. When selecting the boxed eggs, pay attention to the shelf life, so as to ensure the freshness of the eggs.
Purchase products according to relevant certification marks. All kinds of products have their various certification marks to ensure the safety of their food sources. Such as: QS.
Eat less insects vegetables. Eat more seasonal vegetables: The so-called “multiple insects vegetables†are vegetables that are easy to insect pests, such as cabbage, leeks, and spinach. In addition, seasonal vegetables are not suitable for the seasonal season and do not use too many pesticides when planting. .
So how do you understand the label on the package?
Teach you to read food labels
Composition table printed in small print. In 2010, a report titled “Food Label Confusion†by the US Center for Science in the Public Interest pointed out that many food labeling ingredients are deliberately made “unclear†by small print and dense typesetting. Some merchants even intentionally print food ingredients in different colors that are confused with the background color, or print the ingredient list on the folds of the outer packaging, making it difficult for consumers to identify.
Misled health care. This product “helps improve immunity†and “helps protect joint healthâ€... Nutrition advocacy such as this not only obscure but also mislead consumers. A study published in the US “Nutrition Education and Behavior†magazine found that “nutrition marketing†strategies are more common in high-saturated fat, high-sodium and high-salt foods (especially children's foods).
"High fiber" lies. A US survey found that 66% of consumers pay attention to "high fiber" when buying food. However, the purified fiber such as maltodextrin in processed foods does not have the health benefits of fiber from whole grains, fruits and vegetables. Other false fibers include: "Oat fiber", "Wheat fiber" and "Oat fiber".
Hit the "Whole Food" card. The words "made from whole grain foods" on the food packaging do not guarantee that the main raw material of the food is whole grain food. Consumers should be concerned about whether the word "whole wheat" or "whole grain" appears at the top of the ingredient list.
Get a good name for food. Food companies tend to give their unhealthy foods a healthy-looking name. For example, the name “vitamin water†drinks actually contains very few vitamins. "Think thin" nutrition bars, "smart" popcorn and other names sound good, but in fact it is not healthy.
Small package sales. Small packages (small portions) can make unhealthy ingredients such as fats and sugars look less severe. For example, a 15-ounce soup can contains 960 milligrams of sodium. According to the United States Department of Agriculture, its sodium content is "unhealthy." If you use a small package, split into two, each containing 480 milligrams of sodium, which is listed as a healthy food.
Finally, there are shopping tips for bulk food.
How to choose bulk food
Cereal bulk foods. Bulk grains are prone to germs and nutrient losses are also large. Because the grain contains moisture, a relatively humid environment can cause germs to grow. Among them, the most harmful to the human body is a carcinogen aflatoxin. Among the grains, brown rice cannot be purchased in bulk. Although it is nutritious, it has a short shelf life, usually only six months. In particular, vitamin A and vitamin C, which are left in the air for about three months, are completely oxidized and their health effects are lost.
Bulk edible oil. Most of the bulk edible oils do not have packaging marks. They are no name, site, no production date, shelf life, no quality standards, "three no" products, there are serious health risks, do not buy. In particular, the purchase of large quantities of cooking oil at one time is even more important. This is because, for one, the uncovered oil is usually stored in the kitchen. The temperature is high, humidity is high, and bacteria are easy to grow. Second, the oil in the oil is prone to oxidation and rancidity, which increases the risk of cancer. Therefore, experts recommend that edible oil should be bought in small packages and eaten within 3 months of opening. At the same time, it needs to be reminded. The preservation time of edible oil is also related to the type of oil. For example, olive oil can only be preserved for 6 months, and peanut oil can only be stored for 3 months after opening.
Bulk frozen foods. Do not think that frozen foods can be stored for long periods of time without fear, and its shelf life is actually only one or two months. It is not easy to judge how long it takes to store and store frozen foods in supermarket freezers. Therefore, don't let frozen dumplings, frozen meats, etc. fill the refrigerator freezer when you're working again. Frozen foods are best bought now.
Bulk seasoning products. Whether it is bulk peppercorns, cumin, or bottled chili sauce, the taste will be generally reduced in about half a year, the seasoning ability will be weakened, and bacteria will grow easily, posing great health risks. Condiments must be bought less and more refined, it is best not to buy bulk or large bottles.
