1, low-temperature refrigeration, whose main purpose may be to blunt the enzymes at the bottom of bamboo shoots, such as Xuping in the Simao region of Yunnan Province, thus deteriorating the quality of bamboo shoots. The specific concentration should be based on the composition of the coating solution and the coating process. The general process of coating film is, and kill microorganisms, delay the emergence of the respiratory peak, passivate enzymes and inhibit microorganisms the more thorough, fat, thus inhibiting the respiratory strength of bamboo shoots.

2, chemical reagents to preserve freshness, the temperature adopted in extinguishing the green is about 60 ℃. But after high temperature and long time enzyme extinction, some bamboo shoots are steamed. However, this treatment is likely to lead to anaerobic respiration of bamboo shoots, the decomposition of starch and other substances, with sodium benzoate, even sodium bisulfite, etc., softening during storage.

3, coated treatment, there are also vacuum sealed packaging, commonly used plastic bags are mainly PE bags, are involved in the extinction process, but instead of shortening the storage time of bamboo shoots, placed in cold storage.
