Problems solved by technology

[0004] Persimmon dates have many fruits and few pests, and people only have traditional hand-made methods for processing persimmon dates. In this way, it is difficult to guarantee the output and output speed of dried persimmon dates, which will easily lead to the stagnation of the production chain. Jujubes are still processed by manual methods of peeling and drying in the sun. During the production process, it is very easy to be polluted, moldy and blackened, which will affect the color and quality of dried persimmons. In case of rainy or cloudy weather, most fresh persimmons and jujubes will rot On the tree
Due to the lack of a perfect processing process, the sanitation during processing cannot be guaranteed

Abstract

The invention relates to a processing method of diospyros zhejiangensises. The processing method comprises the following steps: (1) collecting the diospyros zhejiangensises, and peeling; (2) carrying out drying group treatment or airing group treatment on the diospyros zhejiangensises in the step (1); (3) after the diospyros zhejiangensises are kneaded each time in the step (2), respectively collecting three diospyros zhejiangensises in each processing method, shooting, and determining weight and hardness of the diospyros zhejiangensises and nutritional ingredients of finally processed dried diospyros zhejiangensises, wherein indexes of the nutritional ingredients are soluble sugar, total phenols, ascorbic acid, tannin and DPPH (1,1-diphenyl-2-picrylhydrazyl); and (4) carrying out analytic statistics on data. Compared with a conventional processing method, the processing method has the advantages that the influence of the rainy weather can be prevented, pollution-free and environmental-friendly dried diospyros zhejiangensises are processed so that a processing mode of the diospyros zhejiangensises is of a mechanical production, the income increase of farmers is promoted, the status of products of the diospyros zhejiangensises in the international market is improved, a great theoretical direction and practical significance is achieved in the development of relevant industries, and the further development of the dried fruit market is greatly promoted.

Description

Technical field [0001] The invention involves a processing method of persimmon and jujube, which is a processing method to maximize the nutritional component of persimmon and jujube under pollution without pollution. Background technique [0002] Persimmon jujube ( Diospyros zhejiangnsis ), Ebenaceae (eBenaceae) persimmon ( Diospyros L.) Plants.When its fruit is mature, it looks like a jujube.Persimmon jujube is rich in nutrition and rich in substances such as vitamin C. High medicinal value can help digestion, moisturize the lungs and phlegm, clear heat and detoxify and other medicinal effects.After the drying, the flavor is unique, sweet and thick, and endless aftertaste.Modern society's high quality and unique requirements for material make people have a greater demand for peculiar dried fruit such as persimmon and jujube. [0003] The origin of persimmon and jujube is limited to Lishui and Jinhua's Yongkang in Zhejiang, China. It is still in the initial development and utiliz...
