Sensory characteristics sensory characteristics: color, white, light yellow, fine fluffy powder, popcorn smell, soluble in water. 1 nutritional characteristics, high digestibility: extruded product temperature, high pressure, high shear forces of the starch granules swell and gelatinize the starch molecular chain is opened, increasing the surface area of ??the particles of chyme, greatly improving the digestibility, while part of the protein peptide chain cleavage of peptides and amino acids, the absorption rate of protein is also greatly improved. 2, strong lure diet and health: the corn and has a special flavor, can significantly improve the palatability, puffed corn starch digestion fast (RSD78%) of content than corn starch digestion index (SID) hit 98 percent, the large intestine low degree of fermentation of diarrhea have a higher rate of protection. 3, toilet elevation: hot extrusion production makes salmonella, E. coli and other harmful bacteria kill all cases significantly improve the health indicators of feed. Suitable for use objects: milk, pigs and other young animals, fish, shrimp and other animals weak digestion.
