Will the nutritional quality of prefabricated dishes be reduced compared to the current meals?

The topic of prefabricated dishes has been hot recently. Economists have said that prefabricated dishes are a "blue ocean", especially in the post -epidemic era, the production capacity and consumption of prefabricated dishes are growing rapidly. Many self -media bloggers and news reports also say that "prefabricated dishes are occupying takeaway and eating food". Everyone's evaluation of it is mixed. What is prefabricated? Is it safe? Compared with freshly made dishes, will the nutritional value of prefabricated dishes worse? Let me share some related thinking with my own superficial understanding.

There are four types of prefabricated dishes

Some also need to be cooked on fire instead of food

According to the group standards (T/CCA) released by the Chinese Culinary Association, the so -called prefabricated dishes are "one or more agricultural products as the main raw materials and use standardized flowing operations. , Molding, seasoning, etc.) and/or pre -cooking (such as frying, frying, baking, cooking, steaming, etc.), and make pre -packaged finished or semi -finished dishes. "

Prefabricated vegetable products are divided into four types, namely foods, hot, cooked, and distribution of prefabricated dishes. Among the prefabricated vegetable products, some are consumers who buy it directly, and the other part has entered a catering company, and some have entered a food processing enterprise.

Type 1: 类 食. It is a product that has completed the sterilization system that can be directly eaten after opening. Canned and soft canned foods, such as pocket chicken, bag sauce beef, etc., can be included in the prefabricated dishes. However, many dishes are now placed in a composite film or aluminum foil bag and packed in a carton instead of being installed in the canned tinnum shell or glass cans.

Type two: that is hot class. After cooking, it is already cooked or semi -cooked. For example, an instant curry rice, just put the heat -resistant composite film bag in boiling water for several minutes, or open the bag to the bowl, then cover a plate, and eat it in the microwave oven for two minutes. It does not need a kitchen, as long as there is an electromagnetic cooker, a microwave oven or rice cooker.

Type 3: Cooking. A certain processing process of the main raw materials has been completed, and it is equipped with or unsuitable products that can be edible after cooking. In other words, the food is not familiar, but it is already a semi -finished product, and it can be eaten quickly and cooked directly.

According to this concept, frozen roasted chicken wings, frozen chicken and rice flowers, and frozen frozen skewers can be regarded as cooking. A large number of products such as quick -frozen dumplings, frozen buns, and quick -frozen pie can actually be classified as this category. There are also some catering companies that provide big dishes, such as frozen fish fillets, semi -cooked meat, and well -equipped seasoning. Tengteng's just cooked food. This type of product requires consumers to have cooking facilities, and may also need to be equipped with onion coriander.

Type 4: The distribution. It is a product that is processed by simply processing and cutting, which is processed or not equipped with auxiliary materials. The raw materials are washed, processed, and cut off, and you can use it in the dishes immediately. For example, the meat becomes a flavoring shredded pork, and the fish becomes the cut fish pieces or sashimi; some small packaging, frozen or refrigerated animal and plant ingredients can be matched with the bag. This type of product requires consumers to have a certain cooking ability, but it is more troublesome than purchasing and processing raw materials from scratch.

Pre -processing ingredients

No one does not have nutritional value

What is the safety of prefabricated dishes, it is difficult to answer in a word. Theoretically, compared with foods that are rationally made with high -quality fresh and natural ingredients on -site and consumed immediately, the room temperature is stored for several months or frozen foods for several months, and the nutritional value will inevitably decline. After the heating again, it should cause more nutrient losses than a heating.

But how far is it? This matter cannot be generalized.

Prefabricated dishes can be stored for a long time, which does not mean that it is low. Just as canned food can be stored at room temperature for two years, it does not mean that it is not safer than restaurants. Because from the perspective of the food industry, for food that can be heated and frozen, the technology of preventing and corrupting corruption of microorganisms has long matured.

Theoretically, as long as it is sterilized and canned (including soft cans), the process operation specifications are standardized, that is, the prefabricated dishes of the food type, that is, the prefabricated dishes are preserved at room temperature for more than 6 months. The shelf life of specific products can be between half a year and two years). At present, the cold chain distribution and cold chain sales systems in cities are becoming increasingly developed. Many prefabricated dishes that are hot and cooking types can be made into quick -frozen products. As long as the temperature remains stable, they can be stored in the cold cabinet of -18 degrees Celsius for 12 months.

At present, the Chinese Culinary Association has formulated the group standards for prefabricated dishes. Theoretically, qualified prefabricated vegetable products can meet food safety standards.

Most of the chain catering institutions will use prefabricated semi -finished products

Most of the chain catering institutions now adopt the method of prefabricated semi -finished products, which is also a type of prefabricated dish. Without a variety of prefabricated semi -finished products provided by the central kitchen, there is no way to support the supply of high -efficiency, safe, and quality -uniform catering food.

For example, fries are pre -frozen or refrigerated in advance, just fry in the store. Many half of the finished products such as dumpling filling, bun filling, fermented dough, and pizza billets are also pre -made in advance. The seasonings of many dishes are uniformly prepared, and the broth is also uniformly tuned. Generally speaking, large -scale brand products are more reassuring, because larger enterprises usually have a more standardized management system, sufficient technical personnel, and the strength of conventional inspection and monitoring. It's easier to supervise. Even if there is anything, the negative information of the big brand will be exposed quickly, causing media attention, so they will have a lot of quality pressure and must do food safety management. As for those small workshop products without regular management, it is difficult to say.

Match, that is, cooking prefabricated dishes

The impact on nutritional value is smaller

As the pace of life is increasingly accelerated, people are tired of tedious housework. In order to save time and worry, buying prefabricated dishes is like ordering takeaway, which will become people's daily choices.

Prefabricated dishes that are cooked or cooked through refrigerated or freezing treatment are relatively small on nutrition.

In contrast, the prefabricated dishes that are hot and 言 相, because after being cooked, it must be heated after being cooked, which has a slightly greater impact on nutritional value. At the same time, some products also have problems such as high fat content, high sodium content, high energy density, and low vitamin content.

In fact, hot, 即 其实 prefabricated dishes can make higher nutritional value, but meeting this demand will increase costs.

For example, less oil and salt means that the quality of raw materials is higher, and it is more difficult to store for a long time. Another example is to increase the number and variety of vegetables, you need to overcome some problems that are easy to worse after the long -lasting vegetables and colors are worse, and the volume should be greatly increased to increase the cost of transportation and storage.

That is, food dishes do exist

There are more oil and salt, less vegetable ingredients and so on

Research data from various countries prove that the rational frozen ingredients can still preserve most of the nutrients. In the dietary guidelines of European and American countries, they even attribute frozen vegetables and fresh vegetables to one category, which also encourages consumers to eat. For example, frozen tender peas, tender beans, carrots, sweet corn kernels, etc., have become part of daily cooking raw materials. Families, restaurants, canteens are used. Canned tomatoes, canned mushrooms, canned corn bamboo shoots, canned straw mushrooms, canned asparagus and other ingredients often appear in various restaurants. Those frozen pork, fish fillets, shrimp, etc., which can be handled and opened to open the bag, are not more loser than buying frozen fish frozen meat and then home cooking.

Everyone is more worried about that is the kind of food. For example, after buying a pack of potato curry chicken, I always feel that I have not made good nutrition.

This idea does make sense.

The dishes of the category can be regarded as a soft canned product. On the one hand, they have been heating for a long time, and more vitamin losses will be more. On the other hand, there are often problems such as excessive oil and salt and too little vegetable ingredients. Many dishes are used to attract diners with their strong seasonings. There are similar problems such as rice such as rice.

There is a trick with prefabricated dishes "Harmony"

Three ways to eat at ease

If you worry more, we also have a solution logic: prefabricated dishes with other foods.

Method 1: If the vegetable oil is too large and too much salt, it can be paired with vegetables with less oil and less salt or no oil and salt, such as some original lettuce, original cucumber strips, tomato soup without oil.

Method 2: You can also eat roast duck or eat sandwiches. Wrap some salty shredded pork and slices with cake skin or steamed buns, plus original vegetables, and eat together, just like eating roast chicken, you can tear some salty chicken shreds, add some vegetables, add some vegetables, and add some vegetables. Sticking it in the steamed buns or miscellaneous grains.

Method 3: If you are not satisfied with the protein content of prefabricated food, it will be better solved. Add a cooking egg, dipped in strong vegetable juice to eat cucumber and cook eggs. It tastes pretty good.
