辣椒素对草鱼肉防腐效果的初步研究(5700字)
摘  要:本文以辣椒素为防腐剂对草鱼肉的防腐进行了初步研究。单因素试验和正交试验结果表明,以浓度为0.9%的辣椒素溶液浸泡草鱼肉,在密封的状态下于0℃冷藏防腐效果较佳。

The Priliminary Study on the Preservative Effects of Capsaicinoids on Fresh Grass Fish Flesh
Abstract: In this paper, the main research is use capsaicinoids as a preservative for grass carp flesh. Single-factor text and orthogonal test was carried out. The experiment showed that handling the sliced fresh grass carp flesh with 0.9% capsaicinoids could efficiently extend the shelf-life of vacuum packed products when stored at 0℃.
