Method for preparing sugarcane juice beverages and sugarcane syrups by using pressed sugarcane juice of sugar refinery

Abstract

The invention discloses a method for preparing sugarcane juice beverages and sugarcane syrups by using pressed sugarcane juice of a sugar refinery. The method specifically comprises the following technology steps of filtering the pressed sugarcane juice of the sugarcane sugar refinery by a screen or a net, leading ozone, and sterilizing under the cooperation action of ultrasonic waves; adding a chitosan flocculant to clarify, filtering, obtaining a supernatant, heating, and adding composite enzyme for enzyme hydrolyzing; adding activated carbon to discolor, centrifuging by a centrifuging machine, filtering the obtained clear juice by a security filter, filtering by a membrane filtering device, blending and concentrating the obtained clean filtrate, and filling, so as to obtain a sugarcane juice beverage product and a sugarcane syrup product. The method has the advantages that the high-efficiency, continuous and large-scale production is realized, the method is suitable for industrialization, and the economic benefit is good; the produced sugarcane juice beverage product and sugarcane syrup product have bright color, heavy fragrance and sweet taste, can maintain the nutritional matter, flavor and fresh mouth feel of the sugarcane self, and can be more suitable for the requirements of consumers on market.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing sugarcane juice beverage and sugarcane syrup by pressing sugarcane juice in a sugar factory. Background technique [0002] Sugarcane is rich in sugar, of which sucrose, glucose and fructose, the content is about 12%. Sugarcane also contains other substances needed by the human body, such as 0.2 grams of protein, 0.5 grams of fat, 8 mg of calcium, and 4 grams of phosphorus per 100 grams of sugarcane. mg, iron 1.3 mg. In addition, sugarcane also contains calcium, phosphorus, iron and other minerals, aspartic acid, glutamic acid, serine, alanine and other amino acids that are beneficial to the human body, vitamin B 1 , Vitamin B 2 , Vitamin B 6 And vitamin C, and various organic acids such as citric acid, etc. The iron content of sugarcane ranks as the "champion" among various fruits, and it is known as "blood-enriching fruit".

AI Technical Summary

Problems solved by technology

At present, the common problems of sugarcane juice beverages are: (1) red-skinned sugarcane or green-skinned bamboo cane are generally used, and the output of raw materials is not much; (2) the raw material cane must be washed before pressing, and the production efficiency is low; The high-temperature treatment process does not preserve the unique fragrance and flavor of sugarcane juice

Although Chinese patents CN104646221A, CN103330250A, and CN104824778A all involve sugarcane juice drinks or sugarcane syrups, these patents still have the following deficiencies: (1) Sugarcane needs to be cleaned before pressing, which is difficult to achieve mass production and the obtained sugarcane juice is not pressed by sugarcane sugar factories (2) Use high temperature sterilization to kill enzymes, affecting product flavor; (3) Low filtration accuracy, affecting product quality; (4) Insufficient removal of bad flavor components and colored substances in squeezed juice
