不同干燥方式对坦洋工夫红茶风味品质形成的影响

Effects of Different Drying Methods on the Flavor Quality Formation of Tanyang Congou Black Tea

  • 摘要: 为探究不同干燥方式对坦洋工夫红茶品质的影响,本研究采用真空冷冻干燥(FD)、热风干燥(HD)、热风-真空冷冻联合干燥(HFD)、真空冷冻-热风联合干燥(FHD)及微波干燥五种干燥(MD)工艺进行加工,并通过感官审评、理化成分测定和香气物质检测结合化学计量学方法分析对五个干燥茶样进行比较。结果表明,坦洋工夫红茶整体上以甜花香为主,滋味以甜醇为主,其中真空冷冻-热风联合干燥茶样滋味醇正甜爽,甜花香显,感官总分(90.90分)最高。不同干燥茶样的品质成分有较大差异,真空冷冻干燥处理有利于提高茶样的茶红素含量(3.08%);真空冷冻-热风联合干燥处理茶样的游离氨基酸(6.69%)和茶多酚(12.28%)含量显著高于其他组(P<0.05);热风-真空冷冻联合干燥处理茶样的水浸出物(38.23%)含量最高;热风干燥处理茶样的可溶性糖(44.34 mg/g)为其甜醇的滋味特征形成做出贡献;微波干燥处理最大程度保留了茶样的黄酮物质(24.61 mg/g)。5个茶样共检测出99种香气物质,主要包括醛类、酯类和醇类。FD茶样具有独特的青草香和花香特征,主要贡献物质是正己醛(OAV=33.51)、芳樟醇(OAV=75.45)和香叶醇(OAV=239.77);HD处理茶样的甜香和蜜香特征与异戊醛(OAV=254.73)和苯乙醛(OAV=41.44)的富集相关;香叶醇(OAV=210.22)是FHD处理的特征性香气物质;香叶醇(OAV=130.04)和异戊醛(OAV=122.23)是HFD的主要赋香成分;壬醛(OAV=71.89)是MD处理的关键香气成分。本研究系统阐明了不同干燥工艺对坦洋工夫红茶品质的影响,为优化红茶加工工艺提供了理论依据。

     

    Abstract: To investigate the effects of different drying methods on the quality of Tanyang Gongfu black tea, five drying processes were employed in this study: Vacuum-freeze drying (FD), hot-air drying (HD), hot-air-vacuum-freeze combined drying (HFD), vacuum-freeze-hot-air combined drying (FHD), and microwave drying (MD). The five dried tea samples were compared by combining sensory evaluation, physicochemical component determination, aroma compound detection, and chemometric analysis. The results indicated that the Tanyang Gongfu black tea was characterized mainly by sweet floral aroma and sweet mellow taste. Among them, the FHD sample was characterized by a pure, sweet, refreshing taste and a pronounced sweet floral aroma, achieving the highest sensory score (90.90 points). Significant differences were observed in the quality components of the tea samples subjected to different drying methods. FD treatment was found to be conducive to increasing the thearubigins content (3.08%). The free amino acid (6.69%) and tea polyphenol (12.28%) contents in the FHD sample were significantly higher than those in the other groups (P<0.05). The highest water extract content (38.23%) was found in the HFD sample. Soluble sugars (44.34 mg/g) in the HD sample were found to contribute to its sweet mellow taste characteristic. Flavonoids were maximally retained (24.61 mg/g) in the MD sample. A total of 99 aroma compounds were detected in the five tea samples, mainly including aldehydes, esters, and alcohols. The FD sample possessed unique grassy and floral characteristics, mainly contributed by hexanal (OAV=33.51), linalool (OAV=75.45), and geraniol (OAV=239.77). The sweet and honey-like aroma characteristics of the HD sample were associated with the enrichment of isovaleraldehyde (OAV=254.73) and phenylacetaldehyde (OAV=41.44). Geraniol (OAV=210.22) was identified as the characteristic aroma compound for the FHD treatment. Geraniol (OAV=130.04) and isovaleraldehyde (OAV=122.23) were determined to be the main aroma-contributing components for HFD. Nonanal (OAV=71.89) was identified as the key aroma component for MD treatment. This study systematically elucidated the influence of different drying processes on the quality of Tanyang Gongfu black tea, providing a theoretical basis for optimizing black tea processing technology.
