摘要
以草莓为原料,对其打浆后添加果酒酵母进行发酵.在发酵过程中测定菌体浓度、糖度以及酒精生成量.利用Logistic模型、Luedeking-Piret模型和Dose Resp模型,分别建立了酵母发酵的菌体浓度变化模型、糖变化及酒精生成量变化模型.结果表明,模型与实验数据能够较好地拟合,平均误差分别为3.56%、13.01%、11.07%,能够较好地反映草莓果酒发酵过程中酵母菌数、糖消耗及酒精生成量的动态变化.
With strawberry as raw materials,strawberry wine were fermented by adding fruit wine yeast into the strawberry pulp.The changes of the number of yeast,sugar content and ethanol content were determined during the fermentation process of the strawberyy wine.Logistic model,Luedeking-Piret model and Dose Resp model were used to establish the models of yeast fermentation cell concentration,sugar content and ethanol production.The results showed that the model fitted the experimental data well,and the average errors were 3.56%,13.01%and 11.07%,respectively.The model could reflect the dynamic changes of yeast count,sugar content and ethanol content during strawberry wine fermentation.
