摘要:

以蓝靛果果实为原料,经酵母菌富集培养后,分离纯化得到优势酵母菌,并对其进行耐酸、耐酒精、耐亚硫酸及降酸实验,在此基础上利用活化的蓝靛果酵母菌进行蓝靛果酒的发酵。结果表明:蓝靛果酵母菌能够较好地利用柠檬酸与苹果酸,而利用酒石酸的能力较差,并且有一定的耐酒精和耐亚硫酸能力。蓝靛果酵母菌发酵使得果酒的酸度降低了13.2%,对高酸果酒的发酵具有较好的应用前景。

Abstract:

The predominant yeast strain isolated from Lonicera edulis fruits after enrichment culture was tested for its acidresistant, alcohol-resistant, sulfurous acid-resistant and acid degrading properties. This was followed by fermentation of Lonicera edulis fruit wine with this strain after activation. It was found that this yeast strain could utilize citric acid and malic acid well and its ability to utilize tartaric acid was bad. Meanwhile, this yeast strain exhibited the resistance to sulfurous acid and alcohol. Moreover, fermentation with it resulted in a 13.2% decrease of acidity in Lonicera edulis fruit wine. Therefore, this strain will have promising application prospect in the fermentation of high-acidity fruit wine.

Key words: Lonicera edulis, yeast, fermentation characteristics, bio-deacidification, fruit wine
