Description

technical field [0001] The invention relates to a processing method of dried winter jujube, belonging to the technical field of fruit fresh-keeping processing. Background technique [0002] Winter jujube skin is thin and tender, the fruit is sweet and slightly sour, and the color is red and bright. It is also known as "live vitamin pill". Every 100g of winter jujube fruit contains more than 500mg of vitamin C. However, winter jujube is not resistant to storage. In order to lengthen and expand the industrial chain of winter jujube, the main measures are to preserve and process winter jujube to extend the supply period of winter jujube. At present, winter jujubes can be kept fresh for at most 2 to 3 months, so it is difficult to get rid of the dilemma of large output and low price of winter jujubes simply by relying on "fresh food". Therefore, the development of deep processing of winter jujube has become an urgent task for the production of winter jujube. [0003] Winter ju...
