Abstract

The invention relates to a method for preserving fruits, in particular to a method for preserving Chinese dates which solves the problem of short preserving time existed in the existing Chinese date preserving technology and includes the following steps: 1. Preparing preserving liquid, preparing the preserving liquid by adding white sugar in a sodium chloride liquid of 0.5 to 1 percent according to a proportion of adding 20 to 80g by per ml and sterilizing, 2. Using the prepared preserving liquid to treat fresh Chinese dates, crack Chinese dates and fade Chinese dates, 3. Freezing the treated Chinese dates under a temperature of 5 to 20 DEG C below zero for 3 to 6 hours. The preserving period for various Chinese dates after being treated by the invention can be prolonged greatly and the Chinese dates in the first year can at least be ensured to preserve good fresh grade and taste before the Chinese dates are mature in the next year.

Description

technical field [0001] The invention relates to a method for preserving fruit, in particular to a method for preserving jujube. Background technique [0002] At present, the fresh-keeping techniques of fresh jujubes mainly include the following types: freezing and fresh-keeping, that is, putting fresh jujubes in cold storage and storing them at (-5 to -20) degrees. The storage period of this method is relatively long , the storage process does not rot, but the problem of jujube after long-term frozen storage is the loss of edible quality of the fruit, the dehydration rate is as high as 14%, and the final taste is very poor, hard and tasteless. This method requires a lot of energy for refrigeration, so The storage cost is high, and it is basically not suitable for large-scale storage. Controlled atmosphere storage, put fresh undamaged dates into a controlled atmosphere warehouse, and store them in an environment around 0 degrees. Under this condition, the storage period is 6...
