摘要:

选用蒲公英总黄酮提取物和壳聚糖为涂膜材料,研究蒲公英总黄酮提取物对冷鲜肉的保鲜作用。考察蒲公英总黄酮提取物对冷鲜肉感官、理化、微生物等指标的影响。结果表明:蒲公英总黄酮提取物和壳聚糖分别为0.45 mg/L与2.0 g/100 mL时,浸泡时间5 min,冷鲜肉的挥发性盐基总氮含量、pH值、H2S实验和菌落总数的变化能得到有效控制。优化处理后冷鲜肉的保鲜期与对照组比较可延长8 d。证明由壳聚糖和蒲公英总黄酮提取物构成的复合天然保鲜剂具有抑制微生物生长、延长冷鲜肉货架期的作用。

Abstract:

Edible coatings made from chitosan and flavonoid-rich extracts of the whole herb of dandelion were investigated
for their capacity to preserve the quality of chilled pork. The effect of flavonoids from dandelion on the sensory,
physiochemical and microbiological properties of chilled pork was tested. The results showed that by soaking in a mixed
coating solution of dandelion flavonoid extract and chitosan at concentrations of 0.45 mg/L and 2.0 g/100 mL, respectively,
the changes in volatile basic nitrogen (TVB-N), pH, H2S and total number of bacteria in chilled pork were effectively
controlled during subsequent storage, and the shelf life was extended by 8 days compared with blank control. These
observations prove that the composite natural coating can inhibit microbial growth and prolong the shelf life of chilled pork.

Key words: chilled pork, dandelion, flavonoids, coating preservation
