Metal foreign body detection is the key control point of frozen vegetable production
The detection of metal foreign bodies is the key control point of frozen vegetable production.
Therefore, the physical index mainly detects the iron metal and non-iron metal impurities of the finished product, and also includes the detection of hair, insects, sand and plastic in the semi-finished product.
Hair: before the implementation of the average amount of hair per 100 people per day is 8.66 root, after the implementation of the average detection of t is 6.68 root, the difference is statistically significant, insect: before the implementation of the average detection of insects per 10t product is 26.60, after the implementation of the average detection of 23.34, the difference is statistically significant.
Sand stone: the average detection amount of sand stone per 10t product before implementation was 1.75, and the average detection amount after implementation was 0.81, and the difference was statistically significant.
Plastics: The average amount of plastic detection per 10t product before implementation was 1.52, and the average amount of detection after implementation was 0.94, and the difference was statistically significant.
Final product index:
Glass: The average amount of glass detection per 10t product before implementation was 0.04, and the average amount of glass detection after implementation was 0.03, and the difference was statistically significant.
Metal: The average amount of metal detection per 10t product before implementation was 0.23, and the average amount of metal detection after implementation was 0.21, and the difference was statistically significant.

Many people think that frozen food is unhealthy, so they think that frozen vegetables are not as fresh and nutritious as ordinary fresh vegetables. However, the latest research shows that the nutritional value of frozen vegetables is actually higher than that of ordinary fresh vegetables.
In China, related industries supporting the quick-frozen industry, such as flour processing industry, meat and poultry breeding and slaughtering, and cold chain transportation, are far from keeping up with the development of the quick-frozen food industry. Affected by production technology, transportation and other conditions, the quality of frozen food products is still slightly insufficient.
People knew that extreme cold could stop eating meat from "going bad"
English 17th-century writer and philosopher Francis Bacon tried to freeze snow by stuffing it into a chicken, only to be chilled and soon fell ill. Even before Bacon's unfortunate experiment, it was known that extreme cold could stop eating meat from "going bad".
Frozen food is divided into cold food and frozen food
Frozen food is divided into cooled food and frozen food. Frozen food is easy to preserve and is widely used in the production, transportation and storage of perishable food such as meat, poultry, aquatic products, milk, eggs, vegetables and fruits. It is nutritious, convenient, hygienic and economical;
