Behind the convenience, there are also some problems in semi-finished dishes. Semi-finished dishes often put a variety of foods with different properties and different storage conditions in the same carton, which may have the problem of odor. For example, when fish, shrimp and vegetables are mixed together, food quality supervision will have a bad taste and the taste will be greatly reduced.
The raw materials of pork, beef and other meat dishes are processed after frozen storage, and the flavor volatilizes and the taste loses a lot. Fresh fish tastes delicious and tender, while semi-finished fish often has a fishy smell. This is because after freezing, the fish will be more fishy and the texture will be worse.
Nutrient loss.
In the process of storage, transportation, processing and repeated cooking, some vitamins are destroyed and lost, and many semi-finished vegetables will produce nitrite if seasoned. Vegetables without seasoning will evaporate some water during storage, and the nutrition and taste will be lost.
Semi-finished dishes may also be high in fat and salt, which is not good for your health.
