摘 要:利用电子鼻和电子舌研究冷冻、冰鲜和冷鲜小香鸡贮藏期间风味的变化规律。对电子鼻实验数据进行雷达分析、主成分分析(principal components analysis,PCA)和荷载分析(loading),对电子舌实验数据进行PCA分析。结果表明:冷冻、冰鲜和冷鲜小香鸡不同贮藏期挥发性气味和滋味呈现显著差异,贮藏温度越高,小香鸡风味骤变时间越早。冷冻、冰鲜和冷鲜小香鸡挥发性气味发生骤变的时间拐点分别是贮藏24、8、4 d,滋味发生显著变化的时间拐点分别是贮藏12、6、3 d。对冷冻、冰鲜和冷鲜小香鸡电子鼻和电子舌检测数据与感官评分拟合后进行偏最小二乘法(partial least square,PLS)分析,相关系数>0.96,表明电子鼻和电子舌能代替感官评定。

Abstract: The changes of flavor characteristics during the frozen, ice and cold storage of Small Fragrant chicken broth were investigated by electronic nose and electronic tongue. The electronic nose data were analyzed by radar analysis, principal component analysis (PCA) and loading analysis (LA), and the electronic tongue data by PCA. The results showed that there was a significant difference in the volatile odor and taste of Small Fragrant chicken broth at different storage periods. The flavor deteriorated earlier at higher storage temperature. The volatile odor changed significantly at 24, 8, and 4 days of frozen, ice and cold storage separately, and the taste changed significantly at 12, 6 and 3 days separately. The sensory scores were fitted against the instrumental data and analyzed by partial least square (PLS) regression to obtain correlation coefficients greater than 0.96. These results show that electronic tongue and nose can be an alternative to sensory evaluation.

榕江小香鸡是贵州地方优良土鸡之一[1],于2006年被列为国家品种资源平台建设项目,并于2014年9月获得“国家地理标志保护产品”认证[2]。在农村粗放饲养条件下,小香鸡长势缓慢,生长周期长,饲养成本高,营养成分在生长过程中得到不断积累,肉质细嫩,味道鲜美,香气独特,风味特征物质含量远超过其他鸡种,是纯天然的“味精”。目前,小香鸡相关的研究主要集中于品种概述[3-4]、基因组学[5-6]和养殖[7-9]等方面,而关于其贮藏的研究较少。
在禽肉贮藏保鲜中,低温保鲜是应用最广泛的保鲜技术[10]。冷冻保鲜是将食品置于-18 ℃以下对其进行贮藏保鲜,适合长途批量运输,但冷冻过程中产生的冰晶会破坏肉的组织,对禽肉风味有一定影响。冰……
