Cane Sugar & Raw Sugar Refinery
Since many years, starch has been converted into glucose using acid and chemicals. With the arrival of enzyme technology, industries have taken the solace of enzymes for accomplishment of this biochemical reaction. Enzymatic conversion of starch depends both on sugar enzymes used and the physical properties of the starch used.
Sugar enzymes accelerate the conversion of starch into glucose. The conversion takes place through the processes namely liquefaction and saccharifaction. Sugarcane plant has many polysaccharides. Cellulose and hemicelluloses, present in cell wall, give the structural strength to the standing cane plant. As they are insoluble in water, consequently they do not affect sugar manufacture. Starch which is responsible for metabolic activity of a growing plant mainly occurs in sugarcane as an insoluble granule. These granules can dissolve during the processing of starch therefore they have an effect on the manufacturing process. Other soluble polysaccharides such as indigenous sugarcane polysaccharides, glucan, dextran are also detected in sugarcane plant.
In liquefaction a starch suspension containing 40-45% dry matter is gelatinised by raising the temperature to steam levels and then liquefied by addition of enzymes. Sugar enzymes hydrolyze the starch matter to maltodextrin which contain mainly oligosaccharides and dextrins. Maltodextrin’s are further converted in the next step called Saccharification. Saccharification is carried with the help glucoamylase enzymes which can hydrolyse starch completely to glucose along with maltose and isomaltose as by-products.
Many other sugar enzymes like Xylanase and Dextranase are also used in this process to reduce viscosity of the mash and for hydrolysis of Dextrans respectively. Dextrans proffer many basic problems in cane processing and juice extraction.
Sugar enzymes manufactured by Nature Bio Science are a cost effective way of sugar refining and sucrose production. These inhibit viscosity during the biochemical reaction, which poses prime hindrance while sugar refining. These help in enhancing the quality of the sugar by elimination of hazardous chemicals during the process. These also contribute a safer working condition during the production process.
