摘要
为了分析和脱除羊栖菜的腥味,本研究使用金银花、柠檬、抹茶和葡萄籽皮等天然植物作为脱腥剂,采用顶空固相微萃取-气相色谱质谱联用分析技术(Headspace Solid Phase Microextraction and Gas Chromatography-Mass Spectrometry,HS-SPME-GC-MS),结合NIST14质谱数据库比对、保留指数分析、气相色谱嗅闻(Gas Chromatography-Olfactometry,GC-O)等方法对其风味物质进行鉴定、分析和综合比较,确定最佳的脱腥剂和脱腥工艺。结果表明:羊栖菜中共检测出24种挥发性风味物质,其中醛酮醇类化合物是腥味的主要来源;通过对比四种天然植物,其中金银花除腥效果最佳,共检测出19种挥发性风味成分,且不仅显著降低了羊栖菜中醛、酮、醇类等主要腥味化合物,还增加了花香味;金银花除腥工艺的最佳条件:4wt%金银花粉、加热温度55℃,加热时间60 min。该研究为羊栖菜的开发和利用提供理论依据。
To analyze and remove fishy substances in Sargassum fusiforme,this study used natural plants such as Japanese honeysuckle,lemon,matcha,and grape seed peel as deodorizers for headspace solid phase microextraction and gas chromatography-mass spectrometry(HS-SPME-GC-MS)analysis.In addition,comparison of the NIST14 mass spectrometry database,retention index analysis,and gas chromatography-olfactometry(GC-O)were performed to determine the best deodorant and deodorization process.The results revealed 24 volatile flavor substances from S.fusiforme,of which aldehydes,ketones,and alcohols were the primary sources of fishy flavor.Among the four natural plant deodorizers,Japanese honeysuckle had the best deodorization effect,and 19 volatile flavor components were detected.Japanese honeysuckle significantly decreased the primary fishy substances such as aldehydes,ketones,and alcohols in S.fusiforme and also increased floral flavors.The best conditions for deodorization processing were addition of 4%Japanese honeysuckle and heating at 55℃for 60 min.This study provides a theoretical basis for the development and utilization of S.fusiforme.
