摘　　要：采用温差-超声波结合的方法对核桃花粉进行破壁处理,考察了不同处理条件对核桃花粉破壁率的影响,并在单因素实验的基础上,以花粉破壁率作为指标采用正交实验优化破壁工艺,得到温差-超声复合破壁的最佳工艺条件为:料液比1:15 g/m L、温差110℃、冷冻时间18h、超声时间35 min、超声功率720 W,此条件下核桃花粉破壁率为83.79%。In this study, the walnut pollen was carried out wall-breaking treatments by the combined method of temperature-ultrasound, the effects of different processing conditions on the pollen wall broken rate were examined. On the basis of single factor experiment with pollen wall broken rate as the index, the optimum process conditions were determined through orthogonal experiment. The optimal technological condition of the combined method of temperature-ultrasound on wall-breaking was as follows： the ratio of solid to liquid 1：15 g/mL, temperature variation 110℃, freezing time 18 h, ultrasonic treatment time 35 min, ultrasonic power 720 W. The broken rate of walnut pollen wall touched 83.79% under the optimum conditions mentioned above.
