Abstract

The invention discloses an apple preservation method and belongs to the field of fruit and vegetable preservation. According to the method, apples are preserved and stored through the steps of pre-harvest treatment, post-harvest treatment, soaking treatment and storage in a fresh-keeping storehouse. Through adoption of the method, the apple quality can be effectively kept, and the apple storage period can be prolonged; the method is practical and flexible, and thus can be adopted for short-term, medium-term and long-term storage; apples which are subjected to post-harvest treatment but not subjected to follow-up treatment can be preserved and stored in a short term; apples which are subjected to soaking treatment and storage in a fresh-keeping storehouse can be preserved and stored in a medium and long term; apples which are subjected to soaking treatment, modified atmosphere packaging and storage in a fresh-keeping storehouse can be preserved and stored in a long term.

Description

technical field [0001] The invention belongs to the field of fresh-keeping of fruits and vegetables, and in particular relates to a fresh-keeping method of apples. Background technique [0002] Apple fruit is crisp, juicy and rich in nutrition. It is generally harvested in the high-temperature season of August and September. Apples that have not been pretreated for freshness will quickly become soft and soft during conventional storage, and their quality will deteriorate rapidly. Reduced value. Softening and browning of apples after picking are common problems in storage. Therefore, delaying fruit softening and reducing browning is of great significance. [0003] Existing commonly used apple storage techniques have passed or failed pretreatment with preservatives, followed by fresh-keeping storage such as ventilated storage, cold storage, 0°C constant temperature cold storage, controlled atmosphere, and ice temperature storage methods.
