Because of the epidemic, this year's CCTV 315 Gala was only broadcast today. I wonder if you have watched it. Food safety issues are definitely a hot topic. This year, CCTV still exposed two food safety issues. Let's take a look. The picture is from Weibo screenshot 01Burger King uses expired ingredients, can we still eat it? "Shelf life" usually refers to the period of time during which no significant changes occur in any aspect of the food. According to the definition of my country's standards, the shelf life is the period during which pre-packaged food maintains its quality under the storage conditions specified on the label. But can we still eat food that has passed its expiration date, such as chicken thighs that have been stored for half an hour? "Shelf life" does not mean safety. Expiration of the shelf life does not mean that the product becomes unsafe, but rather that the quality is poorer. In fact, the term "shelf life" has caused us a lot of misunderstanding. Food within the "best before" date is just a promise from the manufacturer to consumers that it will have the best taste and safety. From the perspective of taste and safety, food within the best before date is of course the best, but expired food can also be eaten if the food storage conditions meet the standards, the packaging is intact, and the color, aroma and taste have not changed. For example, if expired bread is not moldy or hardened, and its color, taste and mouthfeel are normal, you can eat it with confidence; if chicken thighs are older than half an hour, there is actually no problem eating them. Today's party also made me feel like I was riding the Moonlight Treasure Box back to 8 years ago. Eight years ago, I wrote my first popular science article and published it on Guokr.com. What I am more puzzled about is why the same thing that happened to McDonald's 8 years ago happened to Burger King again. If the company cannot do it itself, why does it have to make such a decision? Isn't this just digging a hole for itself? 02 Sea cucumber: Not only is it not good for your health, it may also be poisonous! However, this evening party revealed that sea cucumber farming was exposed to the abuse of DDT, antibiotics and maltodextrin. Eating such sea cucumbers is not only not good for health, but also poses safety risks. Many people are unwilling to believe that sea cucumbers have no nutritional value. Sea cucumber, also known as sea cucumber, sea mouse, and sea cucumber, is a precious marine animal and one of the "eight delicacies" of seafood, along with abalone, bird's nest, and shark's fin. How nutritious is this expensive sea cucumber? Sea cucumbers are rich in protein and contain almost no cholesterol. In addition, sea cucumbers are also rich in calcium, which can reach 285 mg/100 g fresh weight, making them a good calcium supplement. However, eating cheaper calcium-containing foods such as milk and tofu can also fully meet calcium needs, so there is no need to spend so much money. In recent years, studies have found that the fat of sea cucumbers contains a type of saponin that has the effect of preventing tumors; there is also a type of sea cucumber polysaccharide in sea cucumbers that has the effect of improving the body's immune system. No one knows how much of these active ingredients must be consumed to show their effects on the body. Another important reason for the popularity of sea cucumbers is that many people mistakenly believe that eating sea cucumbers can enhance male sexual function. However, the nutritional structure shows that there is no special substance in sea cucumbers that can help men improve their sexual function. At most, it can only provide some psychological comfort. |
