The gelation of the starch refers to the process of swelling, splitting, splitting, splitting, splitting, splitting, typically 60 to 80 ¡ã C) at a suitable temperature (different temperature required, generally 60 to 80 ¡ã C) in water. The nature of the gelatin is a hydrogen bonding between the starch particles and the starch molecules between the starch molecules in the starch, which is dispersed in water into a colloidal solution, and the starch after gelatin is conducive to being resolved by the enzyme. The viscosity increases. XPC China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The process of gellation can be divided into three stages:

(1) In reversible water absorption stage, moisture into the amorphous portion of the starch granules, the volume is slightly expanded, at this time, the cooling is dried, the particles can be restored, and the birefringence is constant; XPC China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
As the temperature rises, the moisture enters the starch microcrystalline gap, and the water is not reversible, and the birefringence phenomenon gradually Blurred, also disappeared, also known as crystallization ldquo; dissolved rDQUO; 3) The final disintegration of the starch particles, and the starch molecule enters the solution.

Starch after gelatinism is also called alpha; – starch. The freshly prepared germinated starch was removed, and it was easily dispersed in the amorphous powder of cold water, ie ldquo; soluble alpha;-starch rdquo;

Method for determining the aldenchism: optical microscopy, electron microscopy, optical transmission method, viscosity assay, swelling And solubility assay, enzyme analysis, nuclear magnetic resonance, laser light scattering method, and the like. At present, there are few companies in the aquatic feed industry to grasp the determination of starch denseness, and enzymatically measure (derived) is basically used.
