摘要
以大黄鱼为研究对象,采用单因素试验探究壳聚糖、没食子酸复配对大黄鱼冰温保鲜效果的影响。通过3因素3水平正交试验,以感官评价与菌落总数为评价指标,进行响应面设计优化。所得最佳保鲜工艺为:壳聚糖添加量0.78%,没食子食添加量0.77%,浸泡时间18.27 min。将样品于冰温条件下(0、-3、-5℃)冷藏,通过对大黄鱼肉质构、HE染色观察和菌落总数检测指标观察,结果表明壳聚糖与没食子酸复配能较好的抑制微生物生长,保持肌肉品质。
This study focuses on the Larimichthys crocea and employs a single-factor experiment to explore the effects of chitosan and gallic acid compound on the refrigeration preservation of the L.crocea.Through a three-factor,three-level orthogonal experiment with sensory evaluation and total colony count as evaluation indicators,Design-Expert 8.0.6 software was used for response surface design optimization.The optimal preservation process obtained is as follows:chitosan addition at 0.78%,gallic acid addition at 0.77%,and immersion time of 18.27 min.The samples were refrigerated at ice temperatures(0,-3,-5℃),and the L.crocea of texture,HE staining observations,and total colony count were examined.Moreover,the compound of chitosan and gallic acid can effectively inhibit microbial growth,and improve muscle quality.
