| 中文摘要: |
| 南美白对虾易发生虾头黑变、腐败变质，冻藏过程中脱水造成干耗，困扰着水产加工业。从抑制虾头黑变、抑菌、保水3 方面筛选出植酸钠、Nisin 以及魔芋寡糖等天然配料，再与具有抑菌、保水、成膜作用的羧甲基壳聚糖进行复配，开发复合对虾保水保鲜剂。结果表明，将0.3% 羧甲基壳聚糖、0.05%Nisin、0.3% 植酸钠、0.3% 魔芋寡糖配制的保鲜保水剂可将对虾货架期延长3~4 d，降低冻藏180 d 的对虾干耗50%。天然对虾保鲜保水剂具有无硫无磷、安全、高效等优点，对保障水产品安全、提高对虾品质，具有重要意义。 |
| 英文摘要: |
| Penaeus vannamei is susceptible to blach change，microbial contamination，drying lose during storage，puzzling aquatic product industry. Sodium phytate，nisin and konjak oligosaccharide，as natural ingredients were selected from test of inhibition shrimp head dark，anti-bacteria and water-holding. Then complex formula of water and fresh-keeping for shrimp was developed for preparation with carboxymethyl chitosan，which had better water and fresh-keeping capacity. The results showed that the shelf life of shrimp could prolong for 3-4 days，and drying loss could be reduced by 50% after 6 months frozen storage，with regeant of 0.3% carboxymethyl chitosan，0.05% nisin，0.3% sodium phytate and 0.3% konjak oligosaccharide. Natural biological water and fresh-keeping agent without sulfur and phosphorus，was safe，efficient，had a larger space for development and prospects in current to food quality requirements. |
