what's food grade hpmc mainly function

Food grade HPMC have multiple function, mainly proferms as follows 
Anti-enzyme performance: The anti-enzyme performance is far better than starch 
Emulsification performance: hpmc can reduce the interfacial tension and  the accumulation of oil droplets to obtain more emulsion stability;
Reduce the amount of fat required: hpmc can enhance the taste, appearance, texture, moisture and gas properties of food that are lost due to the reduction of fat content;
Easy forming : Speed up the process production cycle, improve thermal efficiency, and reduce the formation and accumulation of deposits.
thickening performance: Hydroxypropyl Methyl Cellulose mix with starch could supply the better synergistic effect even add small dosage ,hpmc could offer higher viscosity 
Reduce processing viscosity: 5-1000 pcs hpmc can offer a ideal thickening performance without change temperature
Water loss control: food grade hpmc can effectively control the water in the food from freezing to normal temperature, and can reduce the damage, ice crystals and texture changes caused by cold storage.
