摘要: 采用改性和不改性的魔芋精粉为涂膜材料,对经75%酒精消毒处理或5‰山梨酸钾溶液处理后的鲜猪肉进行涂膜处理,并与不同浓度的壳聚糖涂膜处理相比较,以冷却肉的pH值、过氧化物酶活性、挥发性盐基氮及细菌总数的变化为指标,评价不同处理的保鲜效果。结果表明:冷却肉采用碱法改性的魔芋精粉溶胶涂膜处理保鲜效果与2%的壳聚糖醋酸溶液保鲜效果接近,明显优于其它处理,一级鲜度货架期可达9d。

Abstract: The effect of preservation on chilled meat coated by modified or non-modified konjac glucomannan was studied. Thepork was treated by 75% ethanol or 5‰ potassium sorbate before coating. The pH value,peroxidase activity,TVB-N andbacterial number were evaluation target.The result showed that the preservation effect on chilled meat coated by alkalinemodified konjac glucomannan and 2% chitosan were obviously better than others.The 1st shelf life was 9d.

Key words: Konjac, chilled meat, coating preservation
