富含谷胱甘肽酵母制品在葡萄酒酿造中的应用进展

Advances on the application of glutathione-enriched inactivedry yeast derivatives during winemaking

葡萄酒酿造过程中由于存在较高浓度乙醇、大量酚类物质和溶解氧等因素,易出现发酵缓慢、葡萄酒氧化褐变、香气损失等问题。富含谷胱甘肽酵母制品(glutathione-enriched inactive dry yeast derivatives,g-IDYs)是一种以活性酵母为原料制得的非活性酵母制剂,其能够在葡萄酒中释放大量谷胱甘肽,具有改善发酵迟缓、提高葡萄酒抗氧化能力、增加葡萄酒风味、减少SO_(2)使用量等功能。目前,市场上g-IDYs产品多样,其有效成分差异较大,且在葡萄酒酿造中作用机制不明晰,增加了其有效解决生产问题的应用难度。该文对g-IDYs产品的主要功能成分、在葡萄酒酿造中的应用,以及各物质成分在葡萄酒酿造中作用机制及抗氧化性和测定方法进行了简要综述,为g-IDYs在葡萄酒酿造中的合理使用提供理论参考。

During winemaking process,problems of sluggish fermentation,oxidation,and loss of aroma may occur.As a Inactive yeast preparation produced from active yeast,glutathione-enriched inactive dry yeast derivatives,g-IDYs can release large amounts of Glutathione in wine and achieve positive results such as improvement in fermentation rate,antioxidant capacity,flavor profile,and reduced SO_(2) usage.Currently,there are various of g-IDYs products.However,due to different content of active ingredient and unclear mechanisms of action during vinification,effective application can be difficult.We gave a brief introduction of main active ingredients,application progress,working mechanisms and measurement methods of g-IDYs products,to provide reference to precise application of g-IDYs products.
