Production process of corn glucose syrup
Kaifeng sida is a professional manufacturer of corn syrup production line equipment. Here, kaifeng sida introduces the production process of corn and glucose syrup.
Processing process of glucose syrup for corn raw grain: calcium hydroxide amylase liquefaction residue of corn SO2 solution → caramel preparation;Crushing → soaking → grinding → mixing → liquefaction → filtration → filtrate;Skins, embryo;Ion exchange ← neutralization and decolorization ← saccharification ← pulp regulating ← hydrochloric acid;Glucose syrup activated carbon raw grain of corn processing grape syrup process quality standard 1. Grape syrup: solids 91.44%, reducing sugar 42.03%, boil sugar temperature 165 ℃, the transparency < 3, 0.17% protein, colour and lustre (0.5 N Feetr thick liquid color me) 0.8, ash 0.09%, pH 5.8, lead (Pb) is not detected, copper (Cu) 1.3 parts per million (PPM), arsenic (As) 0.3 PPM.2. Caramel: solid 82.67%, reducing sugar 31.71%, total acid (acetic acid) 0.30%, sugar boiling temperature 11
Production method for processing glucose syrup from corn grain
1. Corn was crushed to remove the husk and germ, and soaked in sulfur dioxide solution at 47 ~ 50℃ for 16 hours to soften the brittle fiber tissue of corn and separate protein from starch.
2. Grind after soaking, adjust the pH value of the pulp to 6.2 ~ 6.4 with calcium hydroxide, add amylase, and use three-stage liquefaction method to liquidate.The liquid slurry is filtered, and the filtrate is adjusted with hydrochloric acid to the pH value of 1.8 ~ 2, hydrolyzed and saccharified under the pressure of 2.8 kg/cm 2, and then condensed into glucose syrup after the decolorization of activated carbon twice and the treatment of fourth-grade negative and cation exchange resin.
3. The liquefied residue also contains some unused starch, dextrin and oligosaccharide, and the starch juice contains about 20%.Water was added to the slag to 25 baume. Malt was added to make corn caramel.
In recent years, some manufacturers have tried making glucose syrup directly from corn, rice or cassava chips.It works.Using corn to produce starch syrup can improve the utilization rate of corn starch, reduce production costs, increase economic benefits, more importantly, no pollution, truly zero emissions, comprehensive improvement of the utilization rate of corn raw materials.
The corn and glucose syrup production line of kaifeng sida is the original syrup production line, which is specialized in producing sweet potato starch production equipment, starch drying equipment and other agricultural products
