1, puffed food contains more salt, polysaccharide and monosodium glutamate, which is very attractive in taste, but long-term consumption of puffed food will affect people's appetite, especially for children in the growth and development stage, and it is easy to "indulge" in puffed food instead of eating staple food.

2. Puffed food has a lot of calories, and long-term consumption will cause obesity, especially puffiness.

3. After the puffed food is fried, baked and extruded at high temperature, the lead content will be very high, because at high temperature, the lead in the metal pipeline of the processed food will vaporize and adhere to the puffed food.

Lead entering the human body is difficult to be excreted. When the lead content in the blood reaches a certain amount, it will affect the hematopoietic system, cardiovascular system, digestive system and nervous system, and people will have symptoms such as anemia, vomiting, anorexia and slow movement.

4. The puffed food becomes "huge" because it contains additives such as expansion agent. In addition, the packaging bag of puffed food also contains a certain amount of aluminum. The human body's ability to expel aluminum is limited. Generally speaking,

Only 65,438+00% to 65,438+05% aluminum can be discharged, and the remaining aluminum will gather in the human body and combine with enzymes, protein and other components in the human body, which will affect human health. Long-term consumption of puffed food will damage the normal function of the brain, and even lead to dementia, developmental retardation, osteomalacia and so on.

Advantages:

1, good taste: the puffed grain product has crisp taste, improved edible taste, and can make coarse grains easily accepted and have a suitable taste.

2. It is helpful to digestion: the starch in raw materials gelatinizes quickly during the expansion process, and the retention rate and digestibility of nutrients are high, which is beneficial to nutrient absorption. In addition, the dietary fiber contained in grains helps digestion.

Extended data:

Protein-rich plant materials are extruded at high temperature for a short time, and the protein is completely denatured, and the tissue structure becomes porous, which is beneficial to contact with human digestive enzymes, thus improving the utilization rate and digestibility of protein;

This product is not easy to regenerate. In the process of grain food preservation, retrogradation is a common problem. Because of retrogradation, the taste of the product becomes rough and the digestibility is greatly reduced.

The raw material of puffed food itself contains no or little lead, and its lead exceeding the standard is mainly related to its processing technology. When processing this kind of food, it needs to pass through metal pipes, and the heavy metals contained in the equipment or pipes will evaporate at high temperature, which is easy to pollute the food.
