Comparative Study on Fermentation Kinetics and Aroma-Active Compounds of Muskmelon Wine Fermented by Three Yeast Strains
摘要
Abstract
This study aims to identify superior yeast strains suitable for muskmelon wine production,by se-lected muskmelon from Tacheng as raw materials and three wine yeasts BV818,SY,and D254 for fermentation trials.The fermentation kinetics and aroma characteristics of muskmelon wine produced by different yeasts were compared,and the variations in total sugar,ethanol concentration,and yeast cell counts during fermentation were dynamically monitored.Volatile aroma compounds were analyzed using headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry(HS-SPME-GC-MS),and the relationships between aroma compounds and sensory attributes were explored through partial least squares regression(PLSR)analy-sis.The results showed that the logarithmic growth phases of strains BV818,SY,and D254 were 0~60 h,0~96 h and 0~84 h respectively.The final ethanol concentrations reached 11.9%,11.4%,and 10.7%indicating that BV818 exhibited the strongest fermentation capacity.The Boltzmann model showed the best goodness of fit(R²>0.99)for yeast growth and total sugar consumption,while the Logistic model showed the highest goodness-of-fit for ethanol production(R²>0.99),accurately describing their fermentation kinetics.A total of 37 aromatic compounds were identified in the pear-melon wine,among which nine compounds,including ethyl butyrate,were determined to be the major active aroma constituents,and the aroma activity value(OAV>1).In 3 kinds of yeast,the BV818 fermented wine contained the highest total amounts of esters,alcohols,and aldehydes/ketones,a moderate level of acids,and exhibited the most balanced aroma profile.PLSR results revealed that isobutyl ac-etate,β-ionone,and nonanal were strongly correlated with fruity notes;ethyl butyrate,phenylethyl alcohol,and 2-octanone were closely associated with melon-like aroma;while decanoic acid,acetic acid,and octanoic acid showed correlations with bitterness.Overall,BV818 was the most suitable strain for muskmelon wine fermenta-tion,endowing the product with an elegant and harmonious combination of fruity and melon-like aromas,and pro-viding a reference for the production and flavor optimization of high-quality muskmelon wine.关键词
