Embodiment 1

[0017] The invention provides a fresh-keeping method of bamboo shoots, comprising the steps of:

[0018] (1) Choose fresh, no mechanical damage, no pests and diseases, the length of the bamboo shoots is roughly the same as the diameter of the base, about 100 catties of bamboo shoots with bamboo shoots, carefully wipe off the soil on the bamboo shoots with gauze, and use a knife Cut off the inedible parts.

[0019] (2) Take out 50 catties of fresh bamboo shoots and immerse the roots in the solution of 0.54% carbendazim and 0.12% sodium propionate for 5 minutes. At normal temperature, the bamboo shoots treated with the solution are placed in the air to dry. Put the dried bamboo shoots into a clean plastic basket, cover the bottom of the basket with sand, place the bamboo shoots vertically, and then bury them with sand, and finally cover the box where the bamboo shoots are in with a polyethylene plastic bag, and place them at 3°C cold storage environment.

[0020] (3) Put 25 ca...

Embodiment 2

[0026] The invention provides a fresh-keeping method of bamboo shoots, comprising the steps of:

[0027] (1) Select fresh, no mechanical damage, no pests and diseases, the length of the bamboo shoots is roughly the same as the diameter of the base, about 400 catties of moso bamboo shoots with bamboo shoots, carefully wipe off the soil on the bamboo shoots with gauze, and use a knife Cut off the inedible parts.

[0028] (2) Select 250 catties of moso bamboo shoots and immerse the roots in a solution of 0.45% carbendazim and 0.15% sodium propionate for 10 minutes. At normal temperature, the bamboo shoots treated with the solution were placed in the air to dry. Put the dried bamboo shoots into a clean plastic basket, cover the bottom of the basket with sand, place the bamboo shoots vertically, and then bury them with sand, and finally cover the box where the bamboo shoots are in with a polyethylene plastic bag, and store them at 2°C cold storage environment.

Abstract

The invention provides a preservation method for a bamboo shoot. The preservation method comprises the following steps: cleaning and trimming a fresh bamboo shoot, wherein the cleaning and trimming refer to gently wiping off soil on the sheath of the bamboo shoot with fingers and cutting off inedible parts using a knife; immersing the root of the bamboo shoot into a preservative solution for 5-10 minutes, wherein the preservation solution is a mixed solution of carbendazol and sodium propionate, and placing the treated bamboo shoot in air for airing; employing a container of which the bottom is fully paved with sandy soil, vertically placing the dry bamboo shoot in the container, burying the bamboo shoot with the sandy soil, keeping the humidity to be 8-10%, and finally, covering the container with a polyethylene plastic bag, and then placing the container in refrigeration house for storage. According to the preservation method, the compound preservative is combined with preservation in sandy soil to effectively inhibit the lignifying and browning degree of the bamboo shoot, and therefore, the consumption of the nutritional quality is reduced; the maintenance of the quality of the bamboo shoot is facilitated; and the storage period of the bamboo shoot is prolonged.

Description

technical field [0001] The invention belongs to the field of food science, and relates to a fresh-keeping technology for vegetables, in particular to a fresh-keeping method for bamboo shoots.
