Problems solved by technology

[0002] At present, the preservation of red dates usually adopts two methods, one is to dry red dates and prepare dry dates with low moisture content, and the other is to make candied dates, which are formed by adding honey to dates and then processing them. The mouthfeel of the red dates prepared in this way deviates from the original taste of red dates. They are dry and lack moisture, so they lack crispness, while candied dates are too sweet, so they are prone to greasy feeling. Due to the poor taste, their consumption is greatly reduced, and the demand is reduced. Its economic value is also greatly reduced

Abstract

The invention discloses a freshness preserving method for red date. The method comprises the following steps: (1) selecting fresh red date just picked from trees and white spirit, wherein the mass ratio of the red date to the white spirit is 100:1-3; (2) uniformly mixing the red date and the white spirit according to the mass ratio, so that the white spirit is uniformly coated to the surface of the red date; (3) putting the red date coated with the white spirit into a fermentation tank, then tightening a tank opening with a plastic film to seal the tank, wherein the fermentation temperature is kept at 0-10 DEG C, and standing for 30-45 days to obtain the freshness-preserved red dates. The method disclosed by the invention is very simple; the freshness of the red date can be ensured by only using white spirit and little sugar as added auxiliary materials; the red date is very low in cost, healthy and environment-friendly; deep processing is not needed, preservatives and the like are not used so as to ensure that the red date is green and environment-friendly; by adopting the method of the invention to preserve the freshness of the red date, the taste is as fragrant, crispy, sour and sweet as red date just picked from trees, eaters like the red date very much, and the edibleness is greatly improved.
