Abstract: Hydraulic cavitation was used to strengthen reaction of modified soybean meal protein by coconut fatty acyl chloride.Factors that affecting the yield of the product such as pressure,time,temperature and material to liquid ratio (volume ratio of water soluble soybean meal solution to coconut fatty acyl chloride),were studied with a set of self-designed hydraulic cavitation equipment.Based on single factor experiments,the optimum conditions were obtained using response surface methodology and surface properties of acylated product were determined.The results showed that the optimal technological conditions for reaction of modified soybean meal protein by coconut fatty acyl chloride with hydraulic cavitation are as follows:pressure,0.29 MPa;time,49 min;temperature,52 ℃;material to liquid ratio,1.8.The product yield achieves 98.1%.The surface performance of the product is fine.
