Jujube preservation method and product thereof

Abstract

The invention discloses a jujube preservation method and a product thereof. The method includes steps: deactivating: breaking walls of jujube cells to release cell content to stop cell biological metabolism; maturing: placing a wall-breaking treatment product to enable jujube to be mature; preserving: freezing a mature product. Wall breaking of the jujube cells is realized through deactivation, sothat the cell content having high-quality jujube fragrance and taste is obtained, cell biological metabolism is stopped, and cryogenic burn is avoided. Sugar is converted into tartaric acid through maturing initiatively, so that the product is easier to digest and absorb and good for health; better taste and fragrance are obtained through maturing, and picked jujubes different in mature degree are enabled to be uniform in mature degree, so that convenience is brought to industrial production management. Freezing slows down and even stops chemical reaction of components in the jujube, so thatlong-time preservation can be realized without adding any preservative. The product is convenient and elegant in eating, convenient for transportation and high in efficiency, and a worldwide problem of jujube transportation and preservation is solved.

Description

technical field [0001] The application relates to the field of jujube preservation, in particular to a jujube preservation method and products thereof. Background technique [0002] Jujube, also known as jujube, has a very high vitamin content and has the reputation of "natural vitamin pills".

Problems solved by technology

[0003] However, on the one hand, jujubes have strong seasonality, and it is difficult for consumers to eat fresh jujubes outside the picking season. Usually, they can only eat dried jujubes outside the picking season.

On the other hand, picking, preserving and transporting jujube is an extremely difficult problem

The traditional practice of picking, storing and transporting jujubes has the following problems: (1) For transportation in different places, only immature or less mature jujubes can be picked. Jujube cannot meet the consumption demand of high-quality jujube; (2) The maturity of jujube is extremely difficult to control in the process of transportation, storage and sales; (3) Low-temperature transportation or storage can easily cause frostbite of jujube, which affects the quality of jujube

However, the drying process will inevitably cause loss of nutrients, and dried jujubes do not have the fragrance and taste of fresh jujubes
