摘要:

为有效解决兰州百合干制过程的褐变问题,开发兰州百合干无硫护色技术,选取护色剂抗坏血酸、柠檬酸、L-半胱氨酸、氯化钠为影响因子,以百合干色泽(L*值)为响应值。在单因素试验的基础上,采用Box-Behnken试验设计构建二次多项式回归方程的模型,进行响应面分析。结果表明:护色剂复合作用对百合干色泽的影响程度依次为:L-半胱氨酸>抗坏血酸>氯化钠>柠檬酸,复合护色剂的最优配方(质量分数)为:0.65%氯化钠、0.3%抗坏血酸、0.3% L-半胱氨酸、0.8%柠檬酸,在此条件下,加工的百合干色泽L*值为78.69,护色效果好。

Abstract:

This study aimed to solve the problem of browning of Lanzhou lily during drying process and to develop a nonsulfur
color-protective agent for dried Lanzhou lily. Four components including ascorbic acid, citric acid, L-cysteine and
sodium chloride were used as influencing factors and the color (L* value) of dried lily was used as response value. Based
on one-factor-at-a-time experiments, Box-Behnken design (BBD) was applied to establish the corresponding mathematical
model. The results showed that the protective effects of these four components on lily color followed the decreasing order:
L-cysteine > ascorbic acid > sodium chloride > citric acid. The optimum formula (by mass) was composed of 0.65% sodium
chloride, 0.3% ascorbic acid, 0.3% L-cysteine and 0.8% citric acid. Under the optimal conditions, the L* value of dried lily
was 78.69 indicating a good color-protecting effect.

Key words: Lanzhou lily, drying process, color-protectiive agent, browning, response surface methodology
