Biological fresh-keeping method of moso bamboo shoots

Abstract

The invention relates to the field of bamboo shoot processing, in particular to a method for biological preservation of moso bamboo shoots, comprising the following steps: cleaning: washing the soil on the surface of fresh bamboo shoot sheaths with clear water with the tips of moso bamboo shoots facing down, peeling off the bamboo shoot sheaths, and cutting off the inedible part of the base of the bamboo shoots; Soaking in white wine: Spray white wine evenly on the surface of moso bamboo shoots, and soak the cuts of moso bamboo shoots in white wine for 5 minutes; drying: dry the bamboo shoots soaked in white wine with cold wind; canning: transfer bamboo shoots into bamboo shoot jars ; 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 clean water 3-4 times, and the interval between each water injection is 2-3 minutes; the biological fresh-keeping solution is a mixed solution of carbendazim and sodium propionate, the mass percentage concentration of carbendazim is 0.45%-0.65%, propionic acid The mass percentage concentration of sodium is 0.1%-0.2%.
