摘要:

研究了抑制雪莲果汁褐变的条件,通过单因素试验选取各因素的水平,根据Box-Benhnken 的中心组合试验设计原理,利用SAS 软件进行响应面回归分析,以褐变变化率为响应值,确定了雪莲果汁褐变抑制条件中各影响因素的水平,结合验证实验结果得到了最佳条件,即抗坏血酸0.31%、DL- 苹果酸0.30%、L- 半胱氨酸0.30%、漂烫温度89℃、褐变变化率20.88%。

Abstract:

In single factor tests, the inhibitory effects of vitamin C (VC), DL- malic acid and L-cysteine (L-Cys) amounts and temperature on yacon juice browning were investigated. Based on the results of single factor tests, the optimization tests of the four factors were designed according to Box-Behnken central combination design principle, and the test results were analyzed by response surface regression. The results showed that optimal inhibitory conditions against yacon juice browning are as follows: VC amount 0.31%, DL- malic acid amount 0.30%, L-Cys amount 0.30% and temperature 89 ℃, and under these conditions the change rate of browning is 20.88%.

Key words: yacon juice, browning, optimization
