Pre-burnt maize starch manufacturers supply large wholesale pre burnt the amount of starch

Pre-burnt maize starch manufacturers supply large wholesale pre Hu added amount of starch, usage and effect: Pre-processing of burnt starch is a simple, versatile modified starch, as long as the application of cold water into a burnt, eliminating the heating Hu of the trouble. Widely used in food, cosmetics, animal feed, oil drilling, foundry, textile, paper and many other industries. The Principle of burnt starch: starch grains at an appropriate temperature (starch from various sources desired temperature, generally 60 ~ 80 ℃) swell in water, split to form a uniform action called burnt burnt-like solution of the role. Hu is the essence of the role of hydrogen bonds in starch molecules of starch grains ordered and unordered (amorphous and crystalline) state between the disconnected, dispersed in water become colloidal solution. Hu of action can be divided into three stages: (1) irreversible absorption stage, the water enters the starch granules amorphous part, a slight expansion of the volume, then cooling and drying, the particles can be restored, birefringence unchanged (2 ) irreversible absorption stage, as the temperature rises, the water enters the gap microcrystalline starch, a large number of irreversibly absorbing, viscosity ≥300-2500mpa.s (2% aqueous solution) PH? value 7 (2% aqueous solution) 80 mesh fineness Ash ≤0.4 packaging, transport and storage Packaging: paper-plastic bag lined with plastic film bag, net weight 25kg. Transportation: available all kinds of transport vehicles, kept dry, and with the rain, waterproof, anti-moisture facility; not with toxic, hazardous, there are other abnormal odor mixed cargo; prohibited rain, water quality and other dirt contamination.
