Processing technology for preparing coconut milk by whole coconut meat wet crushing method

Abstract

The invention provides a processing technology for preparing coconut milk by a whole coconut meat wet crushing method. The processing technology comprises the following steps that S1, fresh and maturecoconut meat is taken and soaked in a sodium chloride solution for 8-12 minutes, the coconut meat is washed with water, and crushed to obtain crushed coconut meat; S2, the crushed coconut meat, nonienzyme and coconut water are mixed, and low-temperature fermentation is carried out to obtain a coconut fermentation product; S3, the coconut fermentation product is added into a sodium carboxymethylcellulose aqueous solution for mixing, coarse grinding is carried out for 4-8 minutes in a wet-method superfine fine grinding machine under the conditions that the coarse grinding frequency is set tobe 20-40 Hz, the rotating speed is 3000-8000 rpm and a grinding disc is 0.3-0.6 mm, and fine grinding is carried out for 2-3 minutes under the conditions that the fine grinding frequency is set to be30-50 Hz, the rotating speed is 9000-12000 rpm and the grinding disc is 0.08-0.12 mm to obtain ground pulp; and S4, the ground pulp is mixed with an annona squamosa extract, a clinacanthus nutans extract and trehalose, uniform stirring is carried out, and after homogenizing is carried out twice, sterilization and vacuum concentration are carried out to obtain the coconut milk. The coconut milk prepared by the processing technology is good in overall stability and has relatively high oxidation resistance and antibacterial property.

Description

technical field [0001] The invention relates to the technical field of coconut processing, in particular to a processing technology for preparing coconut milk by wet crushing of whole coconut pulp. Background technique [0002] The cultivation of coconuts in Hainan has a history of more than 2,000 years since the Han Dynasty. Coconut trees are about 20 meters high, and they begin to bear fruit after 6 to 7 years of planting. They have a productive period of more than 20 years and a life span of 80 years. Autumn is the peak season for coconut harvest. Coconut pulp is mellow and nutritious, and can be used to make coconut sugar, coconut oil, etc. Coconut milk is an emulsified system with high fat content obtained by crushing, squeezing with or without adding water, and filtering fresh coconut meat with the seed coat removed. Coconut milk is widely used, and it is the main raw material of coconut sugar, coconut milk biscuits, coconut milk creamer, coconut milk ice cream and ...

AI Technical Summary

Problems solved by technology

However, the existing coconut milk is often directly obtained by squeezing the coconut fruit, and the coconut pulp is removed, and the utilization rate of the coconut pulp is limited, and the concentrated coconut milk is often added with preservatives, and the fresh-keeping period is limited, which affects the taste of the coconut milk and limits the coconut milk. widely used
