摘　　要：目的研制一种对鹰爪虾具有防腐保鲜作用的复合生物保鲜剂。方法将经复合生物保鲜剂处理过的鹰爪虾在4℃件下冷藏,通过感官评分、菌落总数、pH值、挥发性盐基氮指标的测定,得到最佳保鲜组合。结果最终确定的最优配方为:乳酸链球菌素(nisin)1 g/L,纳他霉素0.2 g/L,普鲁兰多糖5 g/L,柠檬酸5 g/L。结论虾经最优保鲜剂处理后,冷藏6 d时依然保持二级鲜度,处于可接受范围,有效延长了货架期。Objective To develop a new composite biological preservative on Trachypenaeus curvirostris.Methods Trachypenaeus curvirostris were processed by the complex preservative at 4℃,and the results were analyzed by sensory score,colony count,total volatile basic nitrogen(TVB-N)and pH determination.Results The optimum formulation was:nisin 1 g/L,natamycin 0.2 g/L,pullulan 5 g/L,and citric acid 5 g/L.Conclusion The freshness of Trachypenaeus curvirostris treated with the complex preservative is still kept at the second-grade after 6 days,indicating the shelf life can be prolonged effectively by treatment with the complex biological preservative
