摘　　要：花椒麻感强烈、香气独特,被广泛应用于各地菜肴和食品加工中,但同时存在苦味问题。红花椒种植面积和产量大,为明确不同地区红花椒果皮苦味品质差异,以20种不同地区红花椒果皮为研究对象,采用HPLC和氨基酸自动分析仪对花椒果皮苦味物质进行含量测定。研究结果表明,苦味物质在20个地区红花椒果皮中均有分布,含量存在差异。大部分地区槲皮素和熊果苷是主要的苦味物质,含量分别为0.127~1.200 mg/g、0.451~1.918 mg/g。进一步利用聚类分析可将不同地区红花椒果皮聚为五类,通过偏最小二乘判别分析结合变量重要性投影值筛选出异槲皮苷、槲皮素和异鼠李素是不同类别红花椒果皮的关键差异苦味物质。该研究可为红花椒果皮质量控制提供一定数据基础。Huajiao(Zanthoxylum bungeanum),known for its strong pungency and unique aroma,is widely employed in regional cuisines and food processing.However,its development is hindered by its obvious bitter taste.Red huajiao(Zanthoxylum bungeanum Maxim.)has extensive cultivation and production.To compare the bitterness difference in red huajiao peels from different regions,this study focused on 20 distinct regions of red huajiao peels and used HPLC and amino acid autoanalyzer to analyze bitter compounds contents.Results showed that bitter substances were distributed in the red huajiao peels from 20 regions,and the content was different.Quercetin and arbutin were the main bitter substances in most areas,with the contents of 0.127-1.200 mg/g and 0.451-1.918 mg/g,respectively.Hierarchical cluster analysis(HCA)categorized 20 regions into five distinct classes based on bitter compounds composition and contents.Isoquercitrin,quercetin,and isorhamnetin were important bitter compounds influencing the classification of red huajiao peels into different clusters,and they were screened through combined partial least squares discrimination anlysis(PLS-DA)with variable importance in project(VIP).This study establishes a foundational data set for quality control purposes of red huajiao peels.
