| Summary: | Using tangerine peel and honey as the main raw materials, the tangerine peel mead was prepared by fermentation with Saccharomyces cerevisiae LA-FR. Using sensory evaluation as the main evaluation index, the fermentation process of tangerine peel mead was optimized through single factor tests and response surface methodology. And the physicochemical indicators and volatile flavor components of tangerine peel mead were detected and analyzed by conventional detection methods and gas chromatography-tandem mass spectrometry (GC-MS/MS). The results showed that the optimum fermentation process conditions for tangerine peel mead were as follows: tangerine peel addition 1.7%, initial soluble solid content 23%, yeast inoculum 0.11%, initial pH 4.0, and fermentation temperature 28 ℃. The tangerine peel mead brewed under these optimized conditions was amber in color, clear and transparent, with the fragrance of tangerine peel and honey, rich taste, and mellow flavor, and the sensory score was 92.24 points. The alcohol content was 10.60%vol, the total acid content (calculated as tartaric acid) was 4.35 g/L, and the soluble solids content was 9.50%. The total bacterial counts were 51 CFU/ml, no coliform bacteria were detected, and all indicators met the requirements of QB/T 5475-2020 "Mead". A total of 17 major volatile flavor components were detected in tangerine peel mead, including 6 alcohols, 8 esters, and 3 alkenes. Among them, the ethanol (28.36%), D-limonene (18.8%), 2-methylbutanol (16.22%) and phenylethanol (12.07%) had relatively high relative contents. |
