摘要

Effects of processing factors (ultrasound intensity, extraction time, NaCl concn. in extraction solution and ratio of abomasal mucosa to extraction solution) on the extraction yield of goat kid rennet were investigated using abomasa of 2- to 3-wk-old goat kids as raw material. On the basis of single factor experiments, the processing parameters for ultrasound extraction were optimized using a 4-factor orthogonal and rotatory combinatorial design. Results showed that the optimum processing parameters for the extraction of goat kid rennet were: ultrasound intensity, 44 W/cm2; extraction time, 25 min; NaCl concn. in extraction solution, 16%; and the ratio of abomasal mucosa to extraction solution, 1:30. In addition, the ultrasonic extraction proved to be more effective than traditional extraction.
