Cane sugar manufacturing method capable of reducing pigment generation

Abstract

The invention provides a cane sugar manufacturing method capable of reducing pigment generation. The cane sugar manufacturing method capable of reducing the pigment generation comprises the followingsteps of 1) introducing ozone into sugarcane juice, and filtering to obtain sugarcane dregs and sugarcane filtered juice; 2) spraying ethanol solution to the surface of the mixture of the sugarcane dregs and sugarcane residues, and squeezing and filtering again to obtain ethanol extract; 3) dropping an acetic acid-chitosan solution into the ethanol extract, adjusting the pH value to 7.0, and filtering to obtain filtrate; 4) introducing nitrogen into the sugarcane filtered juice, heating, adding phosphoric acid while stirring, uniformly mixing, adding lime milk to adjust the pH value to 6.5, and obtaining supernatant liquid after separation and sedimentation; 5) dropping the acetic acid-chitosan solution into mixed solution of the supernatant liquid and the filtrate, adjusting the pH value,adding nano ferroferric oxide powder, carrying out magnetic field separation, introducing nitrogen into clear juice until the clear juice is saturated and carrying out negative pressure evaporation and concentration to obtain fine syrup; and 6) carrying out sugar boiling, honey separation and drying on the fine syrup to obtain finished sugar. According to the cane sugar manufacturing method capable of reducing the pigment generation, the product has the characteristics of low sugar color value, high quality and the like.

Description

technical field [0001] The invention belongs to the field of sucrose sugar production. More specifically, the present invention relates to a method for producing sugar from sugarcane with reduced pigmentation. Background technique [0002] At present, my country's sugarcane sugar production process mostly adopts sulfurous acid clarification process, that is, calcium sulfate precipitates are formed through the reaction of sulfur dioxide and calcium ions in milk of lime. Calcium sulfate precipitates have strong adsorption capacity, so that calcium sulfate will Pigment, colloid, etc. precipitate together. However, during the precipitation process of calcium sulfate, sulfur dioxide will inevitably remain, so that the sucrose will wrap sulfur dioxide inside the sucrose crystal during the later crystallization process, resulting in sulfur dioxide in the sucrose, which endangers food safety. Studies have shown that oxidase in sugarcane can catalyze the oxidation of polyphenols in ...
