PROCESSING TECHNOLOGY AND ANALYSIS OF AROMA COMPONENTS OF AGARWOOD LEAF BLACK TEA
摘要
Abstract
Single factor and orthogonal experiments were used to optimize the fermentation parameters of agarwood leaves,evaluate the taste of tea soup and determining the physicochemical indexes and aroma components.The results showed the optimal fermentation parameters were as follows:fermentation time of 6 h,fermentation temperature of 30℃,and relative humidity of 90%.The sensory score of the black tea was 83.88 under these conditions.Agarwood leaf black tea has outstanding umami and bitter taste.The transformation of the inner substances occurs during the processing of black tea.A total of 107 aroma compounds were identified from the tea,which were 8 alcohols,24 aldehydes,7 ketones,11 esters,2 acids,3 ethers,23 hydrocarbons,5 aromatics,20 terpenes and 4 heterocyclic compounds.Among them,(E,E)-2,4-heptadienal(741.14µg/kg),nonanal(338.98 µg/kg),hexanal(253 µg/kg),n-hexadecane(244.14 µg/kg),n-octanal(236.98 µg/kg),geranyl acetone(216.09 µg/kg)and limonene(213.21 µg/kg)had relatively high contents.The key aroma components were n-octanal,2-undecenal,trans-2-decenal,α-ionone and decanal,which mainly presented the floral,fruity,light,fat and sweet aroma.The results provide a reference for the processing and quality improvement of agarwood leaf black tea.关键词
