Biological preservation method for bamboo shoots

Abstract

The present invention relates to the field of bamboo shoot processing, in particular to a biological fresh-keeping method for bamboo shoots, comprising the following steps: selecting raw materials, cleaning: selecting bamboo shoots with no rot, no disease, and good shape, and cleaning; canning: transferring bamboo shoots into bamboo shoot cans; Sterilization by boiling: add biological fresh-keeping solution to the bamboo shoot tank, fill it with boiling water, put the bamboo shoot tank into a pressure tank with a steam pressure of 2kg / cm2 for 2 hours, and open the pressure tank to the bamboo shoot tank during the cooking and sterilization process. Inject boiling water 3-4 times, each injection interval is 2-3 minutes; the biological preservation solution is a mixed solution of carbendazim and sodium propionate, the mass percentage concentration of carbendazim is 0.45%-0.65%, sodium propionate The mass percentage concentration is 0.1%-0.2%; Vinegar spraying: open the bamboo shoot jar and pull out the bamboo shoots and hang them up, spray the vinegar on the surface of the bamboo shoots with an atomizing nozzle, and let it air for 25 minutes. The compound adjustment and use of carbendazim and sodium propionate in the present invention can significantly prolong the preservation period of post-harvest fresh bamboo shoots.
