Problems solved by technology

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.
Sugarcane contains a lot of protein and phospholipids, these proteins and phospholipids wrap sucrose, if it is not decomposed to release sucrose, the extraction rate of sucrose will be reduced, and more proteins and phospholipids are also in the precipitation process. Will carry part of the sucrose to precipitate together, thus reducing the extraction rate of sucrose

Abstract

The invention provides a method capable of improving the extraction rate of sucrose for producing sugar by using sugarcane. The method comprises the following steps: firstly, squeezing the sugarcane by using a presser; secondly, spraying composite enzyme liquid onto filter residues until the surfaces of the filter residues are infiltrated, dipping water, carrying out high-pressure homogenization,squeezing and filtering to obtain secondary filtrate and secondary filter residues; spraying an ethanol solution into the secondary filter residues until water drips; then squeezing again and filtering to obtain tertiary filtrate; thirdly, dropwise adding an acetic acid-chitosan solution into the tertiary filtrate to adjust the pH to 7.0, and filtering to obtain filtrate; fourthly, heating the filtrate and uniformly mixing the filtrate with phosphoric acid while stirring, adding limemilk until the pH is 6.5, separating and settling to obtain supernatant; fifthly, adding the acetic acid-chitosan solution into the supernatant, adjusting the pH, adding nanosized Fe3O4 powder, carrying out magnetic field separation, and carrying out negative pressure evaporative concentration on the supernatant to obtain refined syrup; sixthly, carrying out sugar boiling, honey separating and drying on the refined syrup to obtain finished sugar. The method disclosed by the invention has the characteristicsof high extraction rate, low energy consumption in preparation 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 sugar cane that can increase the extraction rate of sucrose. 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. Sugarcane contains a lot of protein and phospholipids, these prote...
