摘　　要：为了解决因海捕鹰爪虾易黑变,对其滥用亚硫酸盐及货架期短等问题,该试验通过正交试验,将壳聚糖与防黑变成分进行复配,研制出一种不含亚硫酸盐的复合型防黑变保鲜剂,并验证了其在鹰爪虾保鲜及防黑变中的作用。结果表明,复合保鲜剂的最佳配比为:壳聚糖0.5g/L、植酸0.5g/L、乙二胺四乙酸(EDTA)0.5g/L、4-己基间苯二酚(4-HR)0.01g/L。鹰爪虾经复合保鲜剂处理后,在(5±1)℃贮藏过程中细菌总数和挥发性盐基氮(TVB-N)增加缓慢,黑变被有效抑制,货架期延长约1倍。通过成本核算,处理1kg鹰爪虾仅需0.22元,具有推广应用的前景。In view of prawn melanosis, sulfite abuse and short shelf-life, a complex preservative （a mixture of chitosan and anti-melanosis material） without sulfite was developed. The effects of Trachypenaeus curvirostris preservation and anti-melanosis were verified. According to the results of orthogonal experiment L9 （3^4）, the optimum composition of chitosan 0.5 g/L, phytic acid 0.5 g/L, EDTA 0.5 g/L and 4-HR 0.01 g/L was determined. Results showed that complex preservative treatment slowed down the increase of aerobic plate count （APC） and total volatile basic nitrogen （TVB-N） of Trachypenaeus curvirostris significantly, and melanosis was inhibited effectively during storage at （5±1）℃. Shelf-life of Trachypenaeus curvirostris treated by the complex preservative doubled almost. The complex preservative has great application prospects, and the cost of processing one kilogram prawns was only 0.22 Yuan.
