Low-DE Starch Sugar From Starch

 　　Glucose syrup, also known as corn syrup, is a liquid starch sweetener used for foods and beverages. Maltodextrin and other spray-dried glucose syrups are used in the instant food industry as flavor carrier and as thickening agent.

　　The feedstock for syrup production is starch milk, which is made from common starch plants such as corn, wheat, rice and cassava.

　　Starting out from starch milk, we design and supply plants for the production of liquid and dried types of low-DE glucose syrups.

　　Low DE glucose and maltose syrups are obtained from starch milk by enzymatic hydrolysis and subsequent concentration.

      PRODUCT ISOLATION AND CONCENTRATION

　　The filtration process to separate suspended solids such as fibers and proteins depends on the product range of the plant.

　　Since syrups with DE values lower than 40 are highly viscous liquids, classical vacuum drum filters or sintered metal cross flow membranes may be chosen. For syrups with a DE value above 40 also polymer or ceramic cross flow membrane filtration are applied.

　　Deashing of the filtered solution is done in a pair of strong acidic and weak basic ion exchangers. Color bodies and foreign tastes are reduced to a minimum by activated carbon treatment. This is done either by passing through vessels filled with granular activated carbon or by suspending and subsequent filtering of the activated carbon powder.

　　To concentrate the solution, a finely tuned system of multiple effect plate type or falling film evaporators is deployed. It is heated by steam and powered by mechanical or thermal vapor re-compression, thus ensuring utmost energy efficiency in combination with minimal thermal stress for the product.

　　The final dry substance content is adjusted to the market demand, or to the subsequent processing steps.
