摘  要:
以冷却牛肉为试验对象,以2%的海藻酸钠、壳聚糖或羧甲基纤维素钠三种多糖为膜材对其进行涂膜保鲜。通过对比和分析保鲜过程中菌落总数、TVB-N值、pH和红度等指标的变化,研究这三种多糖型可食用膜对新鲜牛肉的保鲜效果。结果表明,用海藻酸钠膜处理的牛肉贮藏16 d时,肉的pH为6.2,TVB-N值和菌落总数显著低于壳聚糖或羧甲基纤维素钠组,而且鲜肉质量仍然符合国标规定的鲜肉质量要求。总体上,海藻酸钠膜处理使牛肉的保质期延长,与壳聚糖和羧甲基纤维素钠相比是比较理想的牛肉涂膜保鲜的材料。

摘  要:
2% sodium alginate,chitosan solution or sodium carboxymethyl cellulose was used as film-forming materials to coat chilled beef.Total bacterium counts,TVB-N value,pH value and a* value were determined and used as the beef fresh keeping indicators.The results showed that at the end of the storage on the 16 d,beef coated with sodium alginate had better effects than chitosan solution or sodium carboxymethyl cellulose,and its pH was 6.2;TVB-N and the total bacterium counts were significant lower than chitosan solution or sodium carboxymethyl treatment,and still accorded with the requirements of national standards about fresh meat quality requirment.Totally,the sodium alginate film was the more suitable polysaccharide film on chilled beef coating preservation.
