New technique for processing mulberry juice

Abstract

The invention relates to an air-conditioning storage method for berry juice and fresh mulberries, in particular to a method for processing mulberry juice by using ultrahigh and isostatic pressing sterilization technology, and specially provides a new technique for processing mulberry juice. The new technique for processing mulberry juice comprises a preparation method of mulberry juice and the air-conditioning storage method for fresh mulberries and is characterized in that the preparation method of mulberry juice comprises the following steps of: a) cleaning and selecting; b) deferrization; c) juicing; d) clarifying and filtering; e) ultrahigh and isostatic pressing sterilization; f) sterile filling; g) testing, labelling and warehousing. An ultrahigh and isostatic pressing sterilization device used in the preparation method of mulberry juice has the pressure of 500MPa, and is used for 20 minutes. The liquid mulberry juice obtained in the step a to the step d is the target of the ultrahigh and isostatic pressing sterilization. The air-conditioning storage method for the fresh mulberries is implemented by continuously processing the fresh mulberries for 10 to 14 days by using CO2 at the concentration of 10 to 15 percent, and then sealing in an air-conditioning warehouse for storage.

Description

technical field [0001] The invention relates to a controlled-atmosphere storage method for berry juice and fresh mulberry fruit, in particular to a method in which ultra-high pressure isostatic pressure sterilization technology is applied to the processing of mulberry juice, in particular to a new process for processing mulberry juice. Background technique [0002] Mulberry, also known as mulberry, mulberry, mulberry, mulberry, etc., is the mature ear of the perennial woody plant mulberry (Morus alba L.). Mulberries are rich in sugar, organic acids, free amino acids, multivitamins and a variety of trace elements. It has been used as fruit and Chinese herbal medicine for a long time, and has been listed as one of the agricultural products "both food and medicine" by the Ministry of Health. [0003] my country is the birthplace of sericulture, and mulberry resources are very rich. my country has collected and preserved nearly 3,000 mulberry germplasm resources, and has bred ...

Problems solved by technology

[0004] In recent years, there are patent applications for mulberry fruit juice beverages and their production methods disclosed on China Patent Network, but there are still many deficiencies in these preparation methods of mulberry juice beverages: the special storage properties of mulberry fruit lead to obvious seasonality in the processing of mulberry juice, which cannot be done. Harvesting in one season and processing in multiple seasons has largely restricted the promotion of mulberry juice and the development of the mulberry juice processing industry; the taste of traditional mulberry products is slightly poor, mainly due to the use of heat sterilization The maintenance of functional ingredients is not involved in the processing process, and it is unknown whether the product still has functions
