Problems solved by technology

At present, there are no reports about salicylic acid inhibiting the lignification of bamboo shoots. For the first time, we found that salicylic acid treatment at an appropriate concentration can inhibit the lignification process of bamboo shoots, and has the characteristics of high efficiency and non-toxicity.

Embodiment 1

[0009] Dissolving salicylic acid, citric acid and ascorbic acid in water, wherein the mass percent is 0.01% of salicylic acid, 0.1% of citric acid and 0.05% of ascorbic acid. Select the bamboo shoots harvested on the same day, soak them in the above-mentioned composite fresh-keeping solution for 10 minutes, remove them and dry them with cold air, then put them vertically into cartons, and store them at 1°C for 55 days.

Embodiment 2

[0011] Dissolving salicylic acid, citric acid and ascorbic acid in water, wherein the mass percent is 0.02% of salicylic acid, 0.3% of citric acid and 0.1% of ascorbic acid. Select the bamboo shoots harvested on the same day, soak them in the above-mentioned composite fresh-keeping solution for 12 minutes, remove them and dry them with cold air, then put the bamboo shoots vertically into cartons, and store them at 2°C for 60 days.

Embodiment 3

[0013] Dissolving salicylic acid, citric acid and ascorbic acid in water, wherein the mass percent is 0.03% of salicylic acid, 0.5% of citric acid and 0.15% of ascorbic acid. Select the bamboo shoots harvested on the same day, soak them in the above-mentioned compound fresh-keeping solution for 15 minutes, remove them and dry them with cold air, then put them vertically into cartons, and store them at 3°C ​​for 65 days.

Abstract

A composite antistaling agent for suppressing the lignification of bamboo shoot is proportionally prepared from salicylic acid, citric acid and ascorbic acid through dissolving in water. Its application method includes such steps as immersing the fresh bamboo shoots in said antistaling liquid, drying in air, vertically loading them in paper board case, and storage at 1-3 deg.C for 55-65 days.

Description

technical field [0001] The invention relates to a fresh-keeping technology for agricultural products, in particular to a composite preservative for inhibiting the lignification of bamboo shoots and its application method. technical background [0002] Bamboo shoots are a special vegetable in our country. They are delicious, crisp and tender, rich in various amino acids and minerals, and are known as "the first vegetable among vegetables". my country has a bamboo forest area of ​​about 3.99 million hectares, with an annual output of 1.6 million tons of bamboo shoots, ranking first in the world. However, because the bamboo shoot production areas are concentrated in mountainous areas, the harvest period is short, and the incisions caused by harvesting make them poor in storability and disease resistance. It is difficult to process them in time during the peak season of bamboo shoot production, and it is easy to cause deterioration of the bamboo shoots. The main manifestation i...
