| Abstract: | Objective] To optimize the technologcial conditions for wall-breaking of camellia bee pollen by temperature difference and ultrasonic.Method] With camellia bee pollen as the experimental materials,the method of wall-breaking by temperature difference and ultrasonic was used in pollen,and the single factor and orthogonal experiment methods were used to study the best experimental conditions for temperature difference wall-breaking and ultrasonic wall-breaking.Result] The best experimental conditions for temperature difference wall-breaking were as follows：temperature difference 100 ℃,ratio of material to liquid 1 ∶ 7 g/ml,refrigerant time 24 h,time of water-bath 5 h,temperature of waterbath 45 ℃.Under these conditions,the wall-breaking rate was 68.75％,the total sugar content was 40.02％ and the free alpha-amino nitrogen was 3.58％.And then carried out wall-breaking by ultrasonic.After 10 minutes of ultrasonic processing,the wall-breaking rate reached to 72.41％,the total sugar content was 46.08％ and the free alpha-amino nitrogen was 3.81％.Conclusion] This method has good wall-breaking effect,with low cost,and can be used for small-scale prodtuction. |
