| 摘 要： | 以提高冷冻牡蛎质量为目的，采用自行设计的冷冻装置，分别以魔芋葡甘聚糖被膜液、壳聚糖被膜液及葡甘聚糖和壳聚糖被膜液各为50％的复合液被膜牡蛎进行冷冻试验。采用正交实验，分析了不同方式处理对冷冻牡蛎质量的影响。结果表明，采用被膜液进行被膜可明显降低冷冻牡蛎VBN值和不合格率，提高冷冻牡蛎质量。在被膜液浓度相同状况下，魔芋葡甘聚糖被膜液被膜的效果最好。此外，还对牡蛎葡甘聚糖涂膜液被膜的状态参数进行了优化。

| Abstract: | To improve the quality of frozen oysters, glucomannan , chitosan and a mixture of 50% glucomannan and 50% chitosan were used to coat oysters prior to f reezing and frozen storage for this study. An orthogonal experiment was carried out to investigate the effects. The quality of the frozen coated oysters was ana lyzed. The result showed that the VBN value and freezing loss of frozen coated o ysters decreased with coatings obviously. Glucomannan coating produced the best result. Th e processing parameters of frozen oysters with glucomannan coating were further optimized. |
