What food safety problems exist in real life?

Dyed steamed bread, lean meat, beef sauce, poisonous bean sprouts ... Recently, food safety problems have also piled up, making these little people cry and say that they can't afford to be hurt. From anger, fear to helplessness, but I still have to live, so I can only pay attention when buying food. I have summed up more than two months' experience, which is still comprehensive. Under my shopping precautions, my family is healthy and rosy. ...

Let's talk about meat first. It is impossible for a person not to eat meat. He will be weak without protein.

Distinguish "Clenbuterol": The oil is too thin

There is a layer of fat between the cortex of normal pork and lean meat, and the fat is about1-2 cm; The fat layer under the pig skin fed with lean meat is obviously thin, usually less than 1 cm, so don't buy pork with too thin and soft subcutaneous fat, skin close to lean meat and full lean meat.

In addition, the pork fed with "Clenbuterol" has a dark meat color and bright meat quality, but the fiber is loose, and sometimes a small amount of "sweat" seeps out of the meat surface; Pork cut into two or three fingers wide is too soft to stand on the chopping board.

How to prevent beef sauce? To tell you the truth: real beef is not too cheap, and a catty is at least 15 yuan. Marinate it with "beef sauce" for 2 hours, then add carmine, and the pork will turn into beef. "fake beef" made many citizens shout "terrible".

Pay attention to the cross section when buying meat. Generally, pork fiber is thin and loose, while beef fiber is thick and tight. Pork is high in fat and beef is low in fat. In terms of taste, pork is easy to bite off, while beef is tough and not easy to bite off.

The price of good beef will not be too cheap. If you encounter too cheap beef and mutton, the public had better think twice before you act, and don't be greedy and suffer big losses.

Second, talk about cooked meat.

Most people find it convenient to buy cooked meat, but I tell you, try to eat as little as possible, because there are too many additives, and it is best to make it with fresh meat. If it is really troublesome, pay attention to the following points when buying cooked meat:

Some unscrupulous traders dye fried cooked meat products and fry them into beautiful bright red; There are also some meat products that look beautiful pink after frying and cooking, which is probably because sodium hydroxide is added to the meat. It is useless to eat too much pigment, while sodium sub-X itself is toxic and may react with amino acids to form carcinogenic "sub-X".

So I remind you, when buying cooked meat products, you must not choose too bright colors. Too beautiful colors are generally problematic.

Third, talk about dairy products. Drinking more milk is good.

I only drink one glass of pure milk every day. I haven't caught a cold for six years in a row. I am strong, but I want to drink inferior milk, hehe. . The so-called "milk drink" must be drunk less.

Milk can generally be divided into two categories: milk and milk-containing drinks. Real dairy products include pasteurized milk, ultra-high temperature sterilized milk and yogurt. Its composition is milk, but it does not contain water. The content of protein is generally above 2.3%, and the content of protein in pure milk is generally around 2.9%.

The word "beverage" will be marked on the outer packaging of "milk beverage". In addition to milk, the ingredients list generally includes water and sweeteners, and the protein content is generally only about 1%.

The nutritional value of milk beverage is far less than that of milk, and it can only satisfy the public's pursuit of taste. Children and adolescents in the growing period should pay special attention not to drink milk drinks as pure milk. The additives here are very unhealthy.

The highest nutritional value is fresh milk, which is pasteurized milk. This kind of milk has been sterilized at low temperature (60-82 degrees Celsius), so it must be refrigerated at low temperature, and its shelf life is short, and it can be kept at about 4 degrees Celsius for up to 3 days. The processing technology of pasteurized milk is simple, the price is low, the damage to nutritional components is minimal, and the nutritional value is the highest.

Therefore, the longer the shelf life, the less nutrition. Try to avoid it. If you really have no choice, eat more vitamins and vegetables.

In particular, I want to mention a lot of high-calcium milk, extra-concentrated milk and so on. I suggest you stay away from them. Those things are just added with a lot of additives, which can't be absorbed at all. In fact, they are not as good as pure milk.

"Super concentrated milk" and "high calcium milk" all add nutrients such as fat and calcium to milk. To tell the truth, these additives generally have no obvious effect, and they will cause trouble if they are not used well.

Fourth, talk about staple food.

Is the usual rice, steamed bread and so on, we China people mainly have to rely on these to eat, so we can't underestimate. Take steamed bread for example, there are many things in it. . .

Steamed bread and steamed buns are made of wheat flour, which is usually white with yellow. If you find that the surface of steamed bread and steamed buns is white and smooth, you should pay attention to it, and whitening agents may be added. If it feels soft and tastes like bread, you'd better not buy it. Fillers or excessive yeast can be added. Taibai steamed bread can't afford to be hurt.

However, if the corn flour coarse grain steamed bread tastes as delicate as white flour steamed bread, it is also problematic. Because the main ingredients of this food are not flour, but corn flour and buckwheat flour, which can't be foamed and can only be made into the shape of a corn cob. Most of the yellow glutinous rice cakes and buckwheat cakes on the market are made of flour and synthetic pigments such as lemon yellow and sunset yellow. This is the so-called dyed steamed bread to prevent colored steamed bread: smell the smell of steamed bread, and the fragrant "corn steamed bread" is pungent and the corn flavor is too strong. You can also use blisters, that is, break the steamed bread into the water and observe the color of the water. If the color of water becomes the same as that of steamed bread, it is colored steamed bread. The brighter the color of water, the higher the pigment content.

In the past, I often bought steamed bread, and I liked to eat white bread. Later, my stomach was always uncomfortable and my absorption was not good. Later, I learned that too many additives in Taibai's steamed bread hurt my stomach. Guys, be careful.

Recently, the state allowed additives to be put in rice, saying that it was harmless to the body ... These are beyond our control, so I will talk about the specific experience of buying rice. ...

There must be new rice. The rice in general restaurants is not very fresh;

The color of rice becomes darker, the viscosity decreases, and there is no flavor. The rice with gray powder or white grooves on the surface is old rice. The more the rice, the older it gets. There will be musty smell in old rice, and there will be moth-eaten rice grains in the rice. Grab a handful of rice in your hand, let go and observe whether there is white rice bran powder on your hand. This kind of rice bran powder is rarely seen in qualified new rice.

Hardness is determined by the content of protein in rice. The hardness of rice is stronger, the protein content is higher and the transparency is better. Generally speaking, new rice is harder than old rice, low water decimeter is harder than high water decimeter, and late rice is harder than early rice.

Another trick is the sense of smell:

Take a small amount of rice in your hand, rub it with your hand and smell it immediately. Authentic new rice, fragrant. Old rice, which has been stored for more than one year, only has the taste of rice bran, but has no clear fragrance. If you smell rice and find it has an abnormal taste, it is probably not good rice. Fragrant rice is popular in the market now, and it is normal for rice with natural fragrance. If it is fragrant, it is not normal.

Fifth, talk about vegetables. This piece is the one with the most varieties and hidden dangers.

How do you prevent poisonous ginger? "Poisonous ginger" is smoked with sulfur, which is not only clean in appearance, but also light in color, tender, shiny and thin in skin, and will fall off when it is gently rubbed. Normal ginger is dark and dry, and may also have dirt.

So you'd better buy ginger with soil, it's dirty and clean, and there must be a ghost! !

Beware of insidious vendors: vegetables bitten by insects are not safe either.

People often think that vegetables bitten by insects may be less polluted. Now many vegetable sellers follow this idea, deliberately letting bugs chew vegetables out of holes and then spraying highly toxic drugs. This insect bites vegetables with a lot of pesticide residues.

This is a great move. How to deal with it?

Use Jiejieling bought in a regular store, the kind that can wash vegetables. Soak for 3 minutes, then change to salt water bubble, and finally soak in clear water, so that basic pesticides will be removed. . . But it's quite troublesome

Leek, some people say that leek wrapped in jiaozi is delicious, but who knows that leek is a sin and easy to be polluted. At present, some vegetable farmers use toxic pesticides when planting leeks, because when planting leeks in large quantities, the roots will produce a kind of maggot with particularly tenacious vitality, which can only be killed with toxic pesticides.

Maggots have no choice but to use pesticides.

then what Buy fine leek, not thick leek, it's not safe. And you have to soak it several times when you eat it.

Potatoes are very common, and everyone knows that potatoes with long teeth are poisonous and can't be eaten. However, there are indeed unscrupulous traders who buy sprouted potatoes in large quantities at low prices, clean them and fumigate them with sulfur for several hours. After such "processing", the original green color of germinated potatoes disappeared, replaced by the yellow color of fresh potatoes, and then re-entered the market.

Look at the color, you'd better bring some dirt, and don't be too clean potatoes! Besides, feel it with your hands, it's a little soft. Be careful, this is the characteristic of smoking.

In order to make shrimps grow longer and lay fewer eggs, some unscrupulous traders will put birth control pills and the like in farming. In addition, in order to prevent shrimp from getting sick in aquaculture, some antibiotics will be put in, which will often cause drug residues.

In my own experience, shrimp using birth control pills have almost no eggs, and they can't see golden eggs after cooking, and the size of shrimp is similar. And naturally farmed shrimps, even if hatched on the same day, have different sizes when caught.

That is to say, if the shrimp is particularly neat in size, it is not as normal as different sizes.

Finally, in the face of all kinds of existing food problems, we have to eat and drink, and we can only eat and drink less outside, so we have to do it ourselves! How to eat healthier? I hope the experience summarized above can be used for reference. Life really pays attention to details!
