Abstract：The pure protein foaming agent featured with the shortcomings high production costs, low multiples of foaming.Horn powder, soybean meal, NaOH, chemical foaming agent, thickener, calcium are chosed by the main raw material;hydrolyzed protein foaming agent formulations and conditions of orthogonal experiments, and developed a complex protein foaming agent, through the compound with the chemical blowing agent technology.The results show that: when the chemical foaming agent to 50g, thickener for the 5g, calcium for the 20g, 35g protein foaming agent is obtained when a foam is greater than a multiple of 28 times, settling time is greater than 45h, secretion of water less than 10mL/h protein foam compound.This kind of foam featured with higher foaming abilities, higher foaming times, a foam ability, foam higher stability, foam delicate, etc.
