Abstract

The invention relates to the technical field of freshness retaining of fruits, in particular to a strawberry freshness-retaining method. The freshness-retaining method comprises the following steps: (1) harvesting strawberries when the strawberries are ripe by 70%, uniformly spraying a freshness-retaining agent once every time four days before apples are ripe by 80%, and spraying the freshness-retaining agent to juicy peaches until water drops drop from the juice peaches for 3 days continuously; and (2) harvesting the strawberries when the strawberries are ripe by 80%, wherein the freshness-retaining agent is not sprayed to the strawberries in the harvesting day, and after being picked, the strawberries are directly stored in a preservation box after the preservation box is vacuumized andfilled with nitrogen. The strawberry freshness-retaining method is good in freshness-retaining effect and long in freshness-retaining time, and the taste of the strawberries cannot be affected after freshness-retaining.

Description

technical field [0001] The invention relates to the technical field of fruit preservation, in particular to a method for preserving strawberries. Background technique [0002] As we all know, strawberries have high nutritional value and tender and juicy pulp. However, due to the lack of a hard protective outer skin, strawberries are easily damaged and rotten during transportation. It is difficult to preserve freshness and extend shelf life. Fresh-keeping methods commonly used in the market include cold storage, radiation preservation and PE plastic film preservation, but these preservation methods usually have problems such as high cost, high energy consumption, difficult operation, and unfavorable environmental protection. Therefore, for strawberry To solve the fresh-keeping problem, it is necessary to develop a simple, low-cost, green and environmentally friendly fresh-keeping technology. [0003] In order to achieve this goal, for example, in patent document 1 (applicati...
