Preservation method for bamboo shoots

Abstract

The invention discloses a preservation method for bamboo shoots. The method includes the steps that 1, ultrasonic cleaning is carried out; 2, the bamboo shoots are soaked in a preservation solution, wherein the preservation solution is prepared from, by weight, 10-20 parts of aloe extract liquor, 10-15 parts of honeysuckle flower extract liquor, 3-5 parts of vitamin E, 5-10 parts of chitosan and 10-20 parts of water; 3, ultraviolet radiation is carried out; 4, heat shock treatment is carried out; 5, cooling and non-sealed packaging are carried out; 6, the bamboo shoots are put into an air-conditioned cold store with the temperature of 8-10 DEG C and stored for 1-3 h, and then the temperature of the air-conditioned cold store is regulated to be 2-5 DEG C to continue cold storage. By means of the preservation method for the bamboo shoots, browning, ageing and mildewing of the bamboo shoots can be effectively prevented, the weight loss ratio and rot index of the bamboo shoots can be reduced, the preservation time of the bamboo shoots can be prolonged, the loss of nutritional ingredients can be reduced, the flavor and quality of the bamboo shoots can be guaranteed, and safety and high efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of bamboo shoot preservation, in particular to a bamboo shoot preservation method. Background technique [0002] Bamboo shoots have been regarded as "treasures in dishes" in China since ancient times.

Problems solved by technology

However, bamboo shoots, as vigorously growing buds of bamboo, undergo normal growth and development and accompanying lignification like the buds of other plants under normal growth conditions. After bamboo shoots are isolated, the fiber aging speed is accelerated, and the lignification process is rapid. After 24 hours of storage at room temperature, 60% of the parts will be lignified, and it will almost lose its edible value after 48 hours

In addition, there are microorganisms in the soil. After picking, bamboo shoots inevitably contain some bacteria and fungi, which are prone to fermentation, discoloration and rot during storage.
