Abstract

The invention relates to the field of fruit and vegetable preservation, and particularly relates to a storage and preservation method of vegetable fresh soybean pods. The method comprises the following steps: cleaning and sterilizing the vegetable fresh soybean pods harvested in R6-R7 stages; carrying out pre-cooling treatment; infiltrating in 0.4-1.2 mmol / L exogenous spermine; packaging by a polythene film bag with the thickness of 0.02-0.04 mm, and storing in a refrigeration house of which the relative humidity is 85%-95% and the temperature is 1-3 DEG C. The operation method disclosed by the invention is simple; the yellowing and ageing processes of the vegetable fresh soybean pods can be obviously retarded, and the storage period can be up to 70-85 days.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a storage and fresh-keeping method of fresh vegetable soybean pods. Background technique [0002] Vegetable soybeans [Glycine max (L.) Merr.], also known as edamame, refers to physiologically harvested when the grains fill up to 80% to 90% of the pod length from R6 (bulging grain stage) to R7 (primary ripening stage). The type of soybean harvested is not only rich in nutrition, but also has a sweet, delicious and distinctive taste, which is deeply loved by consumers. Fresh vegetable soybean pods are prone to rust, aging, yellowing and rot due to their strong respiration and vigorous metabolism after harvest, and they are not resistant to storage. At present, chemical methods are mainly used for fresh-keeping treatment. Su Xinguo et al. ("Chinese Agricultural Sciences" 2003, 36(3): 318-323) found that 1-methylcyclopropene (1-MCP) treatment can effectively in...
