Chitosan is a preservative with potent antibacterial activity, and sodium phytate has antioxidant activity and potent ion chelating ability. The present work aimed to explore the effects of chitosan coating combined with sodium phytate (0.1% sodium phytate + 1% chitosan) on preserving Antarctic krill (Euphausia superba) during partially frozen storage. Treatment of chitosan coating combined with sodium phytate significantly suppressed microbial growth, the increases in pH value, total volatile basic nitrogen and sensory deterioration of Antarctic krill (E. superba) during partially frozen storage. Therefore, chitosan coating combined with sodium phytate may be a practical method to suppress quality deterioration of Antarctic krill and thus extend its shelf life.
壳聚糖是一种具有强抗菌活性的防腐剂，植酸钠具有抗氧化活性和强离子螯合能力。本研究旨在探索壳聚糖涂层结合植酸钠（0.1%植酸钠+1%壳聚糖）对南极磷虾（Euphausia superba）在部分冻结贮藏过程中的保鲜效果。壳聚糖涂层结合植酸钠处理显著抑制了微生物的生长，抑制了部分冻结贮藏过程中南极磷虾（E. superba）pH 值、总挥发性碱性氮和感官恶化的增加。因此，壳聚糖涂层结合植酸钠可能是抑制南极磷虾品质恶化、延长其货架期的一种实用方法。
