摘要:

葡萄皮上天然存在着非酿酒酵母属酵母(non-Saccharomyces),主要在葡萄酒浸渍和发酵初期发挥作用,近年来非酿酒酵母属酵母在葡萄酒发酵中的应用受到越来越多的关注。相对于酿酒酵母,非酿酒酵母属酵母在酒精发酵中具有较弱的发酵力,可将还原糖转化为乙醇及其他代谢副产物,是生产复杂风味和低酒度葡萄酒的潜在优良酵母。不同非酿酒酵母属酵母菌种在葡萄酒发酵应用中具有不同的代谢特征,选择具有一定特征的优良非酿酒酵母属酵母应用于发酵中,可以提高葡萄酒的特色化品质。本研究在总结商业化非酿酒酵母属酵母的种类、酿造特点和应用方式的基础上,重点综述了不同非酿酒酵母属酵母对葡萄酒颜色、香气、口感和安全健康4个方面的积极作用、代谢机理和研究热点:具有高产酸、多糖、胞外丙酮酸及低吸附性等特性的非酿酒酵母属酵母可通过不同代谢机理促进葡萄酒颜色的稳定;不同非酿酒酵母属酵母通过低产乙醇、乙醛、降低挥发性酚类,高产乙酸乙酯、乙酸酯类化合物、乙酯类化合物、高级醇、与萜烯或硫醇释放相关的酶类等途径促进葡萄酒果味香气的提升,增加香气复杂性;非酿酒酵母属酵母通过高产甘油、多糖和乳酸,降解苹果酸等方式调节葡萄酒的口感特征;非酿酒酵母属酵母作为生物防治剂可以降低葡萄酒酿造中二氧化硫的用量,通过代谢降解作用减少有毒化合物,提升葡萄酒的安全质量。本文进一步解析了非酿酒酵母属酵母的基因组和微卫星位点分析研究现状,探讨了目前非酿酒酵母属酵母葡萄酒发酵应用研究的主要接种策略,提出了未来研究仍需关注的热点方向,为非酿酒酵母属酵母在葡萄酒酒精发酵中的应用研究提供理论参考。

Abstract:

Non-Saccharomyces yeast are naturally present on grape skin, which mainly play their roles in the maceration and initial stage of fermentation during winemaking process. More and more concerns have been recently focused on the application of non-Saccharomyces yeast in wine fermentation. Non-Saccharomyces yeast often have weaker fermentation ability than Saccharomyces cerevisiae and can convert the reducing sugar into ethanol and other fermentation by-products. Therefore, non-Saccharomyces are the potential excellent yeast for producing wine with complex flavor traits and lower ethanol degree. Different non-Saccharomyces yeast species have different metabolic characteristics in wine fermentation applications. The selection of non-Saccharomyces yeasts with certain characteristics for application in fermentation can improve the specialized quality of wine. This review was based on the initial summary on the species, winemaking traits, and application ways of commercial non-Saccharomyces yeast, and emphasized on the positive role of non-Saccharomyces in wine color, aroma, taste, safety and health, their metabolic mechanisms and corresponding research hotspot. The positive role of non-Saccharomyces in wine color included the promotion of high acid production, high polysaccharide production, high extracellular pyruvate production and low sorption properties. Different non-Saccharomyces yeast could promote the fruity aroma enhancement in wine by low production of ethanol, acetaldehyde, and volatile phenols, and high production of ethyl acetate, acetic acid ester, ethyl ester, higher alcohols, and enzymes related with the release of terpene and mercaptan, and therefore improve the aroma complexity of wine. Non-Saccharomyces yeast could regulate wine mouthfeel traits by high production of glycerol, polysaccharide, and lactic acid, and degradation of malic acid. In addition, non-Saccharomyces yeast could improve the safety quality of wine by decreasing the SO2 dosage as biological control agent, and reducing the content of toxic compounds through metabolic degradation during alcoholic fermentation. This review further analyzed the current research status on genome and microsatellite loci analysis. The main inoculation strategies were discussed on application of non-Saccharomyces yeast during wine fermentation, and six aspects were posed for further research concern. This review provided theoretical references for the research on application of the non-Saccharomyces yeasts in wine alcoholic fermentation.
