Method for processing high-pulp content and concentrated lime juice

Abstract

The invention belongs to the field of orange juice processing and particularly relates to a method for processing high-pulp content and concentrated lime juice. The method comprises the following steps of: 1) soaking lime fruits into potassium permanganate solution for treatment, spraying chloridized water onto the surfaces of the fruits for sterilization, and spraying the fruits with clean waterto obtain clean fruits; 2) squeezing the fruits by using a centrifugal juicer, and collecting lime juice and peel residues; 3) slicing the lime peel residues; 4) debitterizing the lime juice by usingmacroporous resin HDP800, and debitterizing lime peel in a water soaking mode; 5) adding sugar into the lime peel residues, and curing, freezing and storing the lime peel residues; 6) adding honey into the frozen and stored lime peel residues, concentrating the lime juice, vitamin C, citric acid, goldenpomelo essence and the like until the heating temperature is 100 DEG C to obtain semi-finished products of the concentrated lime juice; and 7) sterilizing the lime juice at the temperature of 85 DEG C for 15 minutes to obtain a high-pulp content and concentrated lime juice product. By the method, the flavor substances in the high-pulp content lime juice are preserved to the greatest extent. The method has important significance to the improvement on added value of quince processing industry.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable processing and comprehensive utilization of citrus, and in particular relates to processing lime juice with high-pulp concentrate by using lime pomace and pulp. The production technology route of high-pulp concentrated lime juice was developed. Background technique [0002] The citrus produced in my country is mainly consumed as fresh fruit, and fresh citrus sales account for 95% of the total citrus output, while processing fruit only accounts for about 5%. The citrus processing industry started late, with low processing capacity. 77% of citrus in the U.S. is used for processed products, while my country is far below the overall level of 33% in the world (Deng Xiuxin, China's citrus and its product import and export status and development trend, World Agriculture, 2001, 10: 23-25; Wu Houjiu, Current status and development prospects of China's citrus processing industry, Fruit Trees in South Chi...

Problems solved by technology

At present, the comprehensive utilization of citrus peels mainly focuses on the separation and extraction of functional components in citrus peels, which have the disadvantages of single extraction components, immature on-line industrial production technology, serious secondary pollution, and low utilization rate of raw materials. The peels during processing are used as raw materials, and high-tech is adopted to fully preserve the functional health ingredients of citrus peels and produce flavored health drinks with high pulp content, which not only realizes zero waste in citrus processing, protects the ecological environment, but also makes full use of The functional components of citrus, the development of functional health drinks provides a reference method
