The present invention also provides for a method of removing a sugar from a solution, comprising: (a) providing a solution comprising (i) an IL or ILA phase and (ii) an organic phase, wherein the solution comprises an IL, a sugar and a boronic acid; (b) contacting the sugar with the boronic acid to form a sugar-boronic acid complex, (c) separating the organic phase and the aqueous phase, wherein the organic phase contains the sugar-boronic acid complex, and optionally (d) separating the sugar from the organic phase.

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.

The invention relates to the technical field of food processing, and discloses a brown sugar boiling technology with higher sugar production efficiency. The brown sugar boiling technology comprises following steps: step one, preparing a plurality of fresh sugarcanes, removing leaves and shells from the sugarcanes, removing bitter tips of sugarcanes, and juicing processed sugarcanes by a juice extractor to obtain sugar juice; step two, filtering extracted sugar juice, filling filtered sugar juice into a precipitation container, and adding a flocculating agent to precipitate the sugar juice; step three, filtering the flocculated and precipitated sugar juice by a membrane machine; and step four, adding ion exchange resin into filter sugar juice to remove the impurities in the sugar juice through adsorption, and filtering the sugar juice again by a filter screen. The provided brown sugar boiling technology has the advantages that brown sugar can be boiled in bathes in a short time, the production period is short, the production efficiency is high, the production technology is simple and easy to perform, sugar waste is avoided, and the brown sugar is convenient to use.

The invention belongs to the technical field of food processing and specifically relates to a brown sugar decocting process. By using a mode of adding a mixed enzyme solution to carry out enzymolysisand ethanol extraction on sugarcane crushed substances, sugar in sugarcane bagasse can be furthest extracted so that the sugar manufacturing efficiency is higher; gelatin and bentonite are added to asucrose liquor before being decocted to carry out flocculation on the sucrose liquor so that the sugarcane bagasse mixed in the sucrose liquor can be removed and the sucrose liquor can be clarified; and therefore, the quality of the decocted sucrose is better, and the gelatin and the bentonite also have foam removing effects; as lime does not need to be added during decocting, the obtained brown sugar is more healthy; and 5-6 hours are needed to decoct one pot of brown sugar by using an ancient decocting method. The brown sugar decocting process provided by the invention has the advantages that one pot of brown sugar can be decocted in 40 min on average, the water content of the decocted brown sugar is 3-5%, and the brown sugar freely falls to hard wood ground or ground without being broken from a position with the height of 1 m after being released from a mold.
