Is eating too much fish and tofu good for your health?
When it comes to "tofu", people usually think that it is made of soybeans. But in fact, many products called tofu have little to do with soybeans, and their nutritional value is far less than that of real tofu, and may even bring harm to health, which can be described as "hypocrites" in tofu. Fish tofu. Many people will serve a plate of fish tofu when they rinse hot pot. Although its ingredients may contain a small amount of soybeans, the main raw material is fish sauce. Unfortunately, the source and quality of fish sauce are difficult to guarantee. Fish tofu often contains a lot of sugar, oil and salt, and contains modified starch with thickening effect, which only increases calories but has no nutrition. In addition, modified starch also contains a certain amount of phosphoric acid, which will harm bones if eaten too much.
Fish tofu has always been a controversial issue, that is, whether there is fish in fish tofu. The chef who makes fish tofu said that there must be fish in fish tofu, and people who are allergic to seafood stood up and said, "Nonsense! If there is fish, I am not allergic to it. " First of all, let's pay tribute to the warrior who used his life to seek the truth. Secondly, as a bystander, I think that the soldier ate fake fish and tofu. Otherwise there is no solution to this problem. As we all know, the folk fairy's cottage ability should not be underestimated, and according to what the chef said just now, there is indeed fish in fish tofu, so the problem is coming. Fish and tofu cost so much. Which barbecue stalls are only two yuan for a string of four pieces of fish tofu? How much do they earn? Do they generate electricity with love? Obviously not. Through many investigations and analysis, it is certain that there are two versions of fish tofu. One is made of fish as the main material, ground into fish paste and mixed with other auxiliary materials, then squeezed into pieces and fried. The other is that folk gods directly use starch and condiments to reduce costs.
Fortunately, fake fish tofu itself is harmless, but as a substitute for high-priced fish tofu, it has been restored. Then the problem is coming. One is real fish tofu, and the other is real tofu. How do you choose? Personally, it may be a great burden to eat real fish and tofu all the time, and it is understandable to eat cottage food from barbecue stalls occasionally. But when it comes to fish tofu, the choice of fish tofu is not limited to barbecue stalls. It has become a kind of snack food very well, and it has also successfully entered the tables of some restaurants. As one of the "three major cuisines" in China, braised chicken has already introduced the stone of fish and tofu, developed a unique braised fish and tofu dish, and successfully captured a large number of food lovers.
Do you think fish and tofu will stop when they enter hot dishes? No, obviously not. Some chefs cut fish tofu into pieces, mixed with jellyfish and cucumber slices, and made beautiful cold dishes, which are also delicious. In addition, fish tofu, as a new generation of versatile dishes, can be used to fry eggplant, broccoli, mushrooms and even porridge. As a second-developed dish, fish tofu has been successfully loved by a large number of food lovers. Even the "cottage fish tofu" that appears by mistake allows people who are allergic to seafood to pretend to eat fish. In a word, I like fish and tofu, not picky.
Harm of fish tofu
Eat 9 kinds of additives in one bite of fish tofu. The investigation found that, taking Guiguan brand fish tofu skewers as an example, one piece of fish tofu contains 9 kinds of food additives, such as modified starch, soy protein isolate, wheat starch, flavoring agent, walnut smoke liquid, adhesive, xylose, trehalose and glycine.
Wang Xufeng, vice president of the Capital Society of Healthy Nutrition and Cooking, told the reporter of Life Times that in order to improve the taste, flavor and shelf life of processed food, food additives will definitely be used, as long as the types and dosage of additives are legal, there will be no problem. However, if food additives are used too much, people will not taste the original flavor of food. Moreover, long-term intake of food additives will endanger children's health, but the harm to adults is unknown.
The most common food additives in quick-frozen chafing dish foods such as chafing dish bottom and meatballs are thickener, umami, sweetener, colorant (pigment), color fixative (nitrite), perfume, antioxidant, and even humectant and preservative. Thickeners enhance the taste, umami agents enhance the flavor, and colorants include crab sticks and egg dumplings. Wear a coat that is closest to the color of "real food" and use antioxidants and preservatives at the same time to avoid spoilage of products.

2: Operating process%
Thawing raw meat → mincing → crushing → beating → forming → cooking → cooling → quick freezing → packaging and storage.
Third, the technical points
(1) Thawing: peeled marine fish is used for fish meat, and the residual fish bones are removed after natural thawing, and the final meat temperature is controlled at 0℃-4℃;
(2) wringing: the thawed raw meat is ground with an orifice plate with the diameter of 12mm, and then the ground meat is placed in an environment of 0-4 DEG C for later use;
(3) Crushing: firstly, dry mix carrageenan with a small amount of starch (taken out from the total amount of starch), then add a proper amount of water (taken out from the total amount of water) to dissolve it, then heat the solution to a slight boiling point to fully dissolve carrageenan, further hydrate it, keep it in a slight boiling state 10-20 minutes, and then cold cut it to 10℃. In the production process of fish tofu, crushing is one of the key technologies. The control of time and temperature in the grinding process directly affects the product quality.

(4) Beating: put the beaten raw materials into a beater, add other auxiliary materials, and beat until the minced meat is uniform. During the beating process, ice water is used to control the temperature to ensure that the temperature of meat pulp is below 65438 00℃;
