Sales Training The most commonly used In the acid process, starch- The acid-enzyme process In multiple enzyme removed by sreening followed followed sreening by removed the separate to centrifuging by Starch starch. the from gluten in concentrated and cleaned is ready hydrocyclones of series a conversion. for methods of conversion are acid process, acid-enzyme and multiple enzyme process process. water slurry is acidified and to dextrosereacted and under pressure. After the desired conversion, the process is pressure stopped by releasing and neutralization. Theresulting liquor is clarified to remove suspended solids, decolorized and concentrated to finished density. only is slurry the but similar, is almost with converted, partially The production. dextrose no liquor is then treated with an enzyme and conversion continued until a 42 DE high maltose syrup is formed. The process is then stopped, the liquor clarified, decolorized and concentrated as for the acid process. gelatinized is starch processes, and depolymerized by enzymes rather than acid. www.ametekpi.com

is is a purified High Fructose Corn Syrup Syrup Corn Fructose High Dextrose Monohydrate Maltodextrin Starch is separated from Dextrose Anhydrous Dextrose minimum of 42% fructose on a dry basis. (HFCS) is purified and concentrated D-fructose obtained from edible starch available crystal or in either anhydrous liquid form. remelted other parts of corn by the Cleaned, process. milling wet shelled corn (removed from the cob during harvesting) is ground is It water. in soaked hydro-cycloning by treated and to release the germ which is used for oil extraction. After further grinding, the hull is solid products comparable in comparable solid products composition to theirchemical liquid counterparts. is purified and crystallized D-glucose containing one molecule of water of crystallization with each molecule of D-glucose. purified and crystallized D-glucose without water of crystallization. concentrated aqueous solution of nutritive saccharides obtained from edible starch in which a portion of the has been isomerized dextrose to fructose. It contains a PROCESS INSTRUMENTS PROCESS (dried (glucose syrup)

Corn Syrup Dried Corn Syrup There are many products resulting from these processes, processes, these from resulting define to useful be may it and them: is the purified concentrated aqueous solution of nutritive saccharides obtained from edible starch and having a dextrode equivalent (DE) of 20 or more. glucose syrup, corn which syrupfrom syrup corn is solids) the water has been partially in granular resulting removed, semi- or powdery free-flowing crystalline or amorphose Corn Syrup Process The discovery that starch could be transformed is into a sweet substance 200 years old. approaching the starch In the mid 1800’s, developed industry in Europe mainly on potato starch, of a derived as by-product but in the USA it food crop, corn developed from (maize, corn-on-the-cob). sweet-corn, corn from extracted Starch is hydrolyzed to dextrose. Treatment by enzymes continues the conversion to other sugars such as glucose, maltose and fructose. Corn sweeteners now account for of the 55 percent than more US sweetener market.
