The main causes of food spoilage.
Any food will spoil after being left at room temperature for a while. Some are moldy and clumpy, some are rotten and smelly, and some are sour.
There are 3 main causes of food spoilage:
1. Microorganisms play a role. Microorganisms are everywhere in the environment, and food is easily contaminated by microorganisms during production, processing, transportation, storage, and marketing. As long as the temperature is right, microorganisms will grow and multiply and break down nutrients in food to meet their own needs.
At this time, the protein in the food is destroyed, and the food will emit a foul and sour taste, lose its original toughness and elasticity, and the color will also change.
2. The role of enzymes. There are many enzymes in animal food, and under the action of enzymes, the nutrients of the food are broken down into a variety of lower products. The rice and fruit rot that we usually see are because the carbohydrates are broken down by enzymes and fermented.
3. Chemical reactions of food. Fats are easily oxidized, resulting in a series of chemical reactions, and the oxidized fats have a strange smell, such as fat meat will turn from white to yellow.
Spoiled food not only changes its appearance, loses its original color, aroma and taste quality, but also reduces its nutritional value, and also contains corresponding toxins that endanger human health.

The storage conditions of food are crucial to the quality of the food. The shelf life is usually set according to the relevant suitable storage conditions for the food. During the shelf life, the manufacturer of the product is responsible for the quality of the product in accordance with the relevant standards or express guarantee of the quality conditions.
However, the shelf life is not the only criterion to identify whether a food product has gone bad, and food may spoil prematurely due to problems such as storage methods, environment, etc.
Food with defective packaging is susceptible to moisture or bacterial growth, and is relatively unsafe. The shelf life of food products that have been opened will also be shortened. Therefore, the food should be eaten as soon as possible after opening to avoid mold.

With an iodine content of 18,000 micrograms (only 10 figures for grains and vegetables), seaweed is one of the most iodine-rich foods. Whole grains are a staple food that must be eaten every day, but the plant protein contained in cereals lacks lysine. Lysine is an essential lysine, and the absence of it greatly reduces the utilization of protein in staple foods.
The lysine contained in seaweed is about 5 times that of rice, instant noodles, Fuqiang flour, somen noodles, etc., and about 9 times that of flatbread and fritters. If you put some seaweed when you eat noodles for your baby, a bowl of seaweed soup when you eat rice, and a bowl of wontons with seaweed when you eat a lot of pancakes and fritters, it will easily play a complementary role in protein, and the protein in the staple food will also improve the grade.
