Problems solved by technology

Its processing time is long, the unique aroma of Chinese toon is seriously lost, and the loss of nutrients is large, and the inactivation rate of active substances is high; the processing technology is relatively backward, especially for green leafy vegetables, the phenomenon of chlorosis is very common in the processing process, after processing The products are easily affected by light, heat, acid, alkali and other conditions, and appear green, brown, or even black. At the same time, the crispness of vegetables is also seriously lost, which greatly reduces the value of commodities. The added value of products is low, and social benefits are not good. significantly
