Storage and fresh-keeping method for vegetable-used broad bean fresh pods

Abstract

The invention discloses a storage and fresh-keeping method for vegetable-used broad bean fresh pods. The storage and fresh-keeping method comprises the steps of raw material preparation, product grading, film-coating and pre-cooling, low-temperature storage and the like. The storage and fresh-keeping method is convenient to operate and good in fresh-keeping effect.

Description

technical field

[0001] The invention relates to a method for storing and keeping fresh vegetable broad bean pods. Background technique

[0002] Fresh broad bean pods mean that when the pods are full, the broad bean seeds are light green, and the hilum is yellow, the fresh broad bean pods can be harvested. It is rich in nutrition and delicious, and is deeply loved by the masses. After harvesting, fresh broad bean pods are prone to black spots, aging, softening, and rotting due to their strong respiration, vigorous metabolism, and susceptibility to infection by various germs, and they are not resistant to storage. Have not yet seen the storage and fresh-keeping method of broad bean fresh pod domestic and foreign patent reports at present. The development of efficient and safe storage and preservation technology will solve the problems of fresh broad bean pods in the process of transportation, sales, storage and short shelf life, so as to meet the growing demand for fresh sal...

Embodiment Construction

[0026] (1) Preparation of coating agent:

[0027] Preparation of coating agent: Add 0.9g of glacial acetic acid to 100mL of aqueous solution, then add 1.2g of chitosan and stir until it is evenly dispersed. After fully dissolving, adjust its pH value to 6.0 with sodium hydroxide solution , and then add an appropriate amount of 0.1g nano-silicon dioxide, 1g calcium chloride, and 0.2g nisin (Nisin) in order to stir evenly, and after fully dissolving, a coating agent solution is obtained.

[0028] (2) Raw material preparation: the fresh broad bean pods of the variety Tongcanxian No. 6, the pods are full, the broad bean seeds are light green, and the hilum is yellow, the fresh broad bean pods can be harvested. Select fresh broad bean pods without mechanical damage, diseases and insect pests;

[0029] (3) classifying the fresh broad bean pods obtained in step (2) to obtain fresh broad bean pods with the same number of grains, plump grains and uniform color;

[0030] (4) Coating a...
