苹果枸杞酒的研制及挥发性成分分析

Development of Apple Lycium barbarum Wine and Analysis of Volatile Components

  • 摘要: 为增加苹果发酵酒的口感与风味,提升苹果酒的营养价值,以红富士苹果与宁夏枸杞为发酵原料,以总多酚、酒精度及感官品评为主要指标,分别考察安琪果酒酵母(SY)、和谐A酵母(LA AROM)、诺盟B酵母(LA BAYANUS)、卓越XR酵母(EXECLLENCE XR)、诺盟C酵母(LA CEREVISIAE)5株酿酒酵母的发酵能力,并通过单因素实验与正交试验优化苹果枸杞酒发酵工艺,利用气相色谱-质谱联用仪(gas chromatography-mass spectrometry,GC-MS)分析检测苹果枸杞酒的挥发性成分。结果表明,诺盟B酵母发酵速度最快,发酵所得酒体澄清透亮,香味协调,适合于发酵苹果枸杞酒,其最佳工艺条件为:苹果汁与枸杞汁比例为4:1,初始可溶性固形物10°Brix,接种量3%,20 ℃发酵6 d,所得果酒酒精度为5.7%vol,可溶性固形物为6°Brix,还原糖含量2.15 g/L,感官评分为89.6分。在苹果枸杞酒中共检出32种香气成分,包括乙酸乙酯(17.38%)、辛酸乙酯(1.74%)、癸酸乙酯(2.27%)、苯乙醇(28.2%)、对羟基苯乙醇(12.61%)、异戊醇(9.49%)等香味物质,这些香气成分能在一定程度上增加苹果枸杞酒的风味。实验优化了枸杞苹果酒发酵工艺,提升了苹果酒品质,为果酒的生产研发提供基础理论支撑。

     

    Abstract: In order to improve flavor and taste and enhance the nutritional value of cider, apple and Lycium barbarum were used as the main raw materials to develop a compound wine. The quality of the wine was analyzed by sensory evaluation, Alcohol and polyphenols. The fermentation ability of Saccharomyces cerevisiae (LA AROM, LA BAYANUS, LA CEREVISIAE, EXECLLENCE XR) were investigated. Optimization of fermentation technology of the wine by single factor experiments and orthogonal experiments. The aroma substances in the wine were analyzed by HS-SPME-GC-MS. The results showed that The fermentation speed of LA BAYANUS was the fastest, and the wine clear and bright, fruity and harmonious. The optimum conditions were determined as follows: The proportion was 4:1, the soluble solids were 10°Brix, initial inoculation of 3%, the sequential fermentation was carried out at 20 ℃, for 6 d. The alcohol content of wine reached 5.7%vol and the soluble solids were 6°Brix, the reducing sugar content was 2.15 g/L and the sensory score was 89.6. A total of 32 aroma substances were detected in the wine by HS-SPME-GC-MS, including ethyl acetate (17.38%), ethyl octanoate (1.74%), ethyl decanoate (2.27%), phenylethyl alcohol (28.2%), p-hydroxyphenylethyl alcohol (12.61%) and isoamyl alcohol (9.49%). This aroma components could increase the flavor of wine. The fermentation technology of wine was optimized and increase the quality. It would provide a theoretical basis for the development of fruit wine.
