Problems solved by technology

[0002] During the processing and storage of vegetables, the commodity value is often reduced due to browning. The traditional sulfite color protection agent has good color protection effect and low price, and is favored by manufacturers. However, high doses of sulfur dioxide residues are harmful to the human body. Produce allergies and other side effects, so GB2760 strictly stipulates its residual amount, and when used according to the regulations of GB2760, sulfite cannot achieve satisfactory results
At the same time, some color-protecting and antistaling agents with high safety such as tocopherol, tea polyphenols, sodium phytate, etc. are expensive and have limited effects, especially for some products with relatively high requirements such as bamboo shoots, mushrooms, lotus root, etc. Many manufacturers have to overuse sulfite or store it in cold storage, which greatly increases the risk of the product or increases the cost of the product
