日常英語 關(guān)于食品安全的10個(gè)知識(shí) 上

1. Chocolate with white or grayish film is fine to eat

結(jié)了白色或灰色膜的巧克力也能吃

?

While white or grayish film formed on the surface of chocolate might not look very appetizing, turns out it's perfectly fine to eat. The process occurs when cocoa butter fats separate from the cocoa.

2. Double-dipping can spread bacteria and viruses

二次蘸醬會(huì)傳播細(xì)菌和病毒

?

Sadly, double-dipping is not the greatest idea, since it can spread bacteria and viruses, even when a person isn't visibly sick or unwell. Therefore, it's always best to put dip on your own plate and enjoy it without spreading germs to other people.

3. The 5-second rule is a myth

“5秒規(guī)律”不是真的

?

To test out people's favorite "rule," Dr. Ronald Carter from Queen Mary, University of London did an experiment. He dropped pizza, apple, and toast onto different surfaces and it revealed that they were all covered in germs. As it turned out, the "5-second rule" isn't true—bacteria can attach to food as soon as it touches the floor.

4. Refrigerated leftovers must be tossed out in 3 to 4 days

冰箱里的剩菜必須在三四天內(nèi)丟棄

?

We all know that some types of bacteria can cause illness. However, as it appears, the types of bacteria that do don't affect the smell, taste, or appearance of food. This is why it's crucial to either freeze or throw out refrigerated leftovers within 3 to 4 days.

5. Titanium dioxide that's found in icing has been linked to inflammatory bowel diseases

糖霜里含的二氧化鈦會(huì)導(dǎo)致炎癥性腸道疾病

?

Titanium dioxide—an additive that's used to make white appear even whiter—can be found in a variety of foods, like coffee creamer, icing, powdered sugar, and ranch dressing. However, for the exact same reason, it is used in making sunscreens, laundry detergents, and paint. FDA considers the additive safe; however, there was research conducted that linked it to inflammatory bowel diseases. In addition to this, as of 2020, France has banned titanium dioxide in food.
