以蔗髓为原材料,按照影响酸催化水解的主要影响因素:水解温度(A)、水解时间(B)、酸浓度(C)、液料比(D)先设计单因素试验,然后以L-阿拉伯糖得率为响应值,采用中心组合设计,通过响应曲面法优化酸催化水解的工艺,模拟得到二次多项数学模型,并确定最佳工艺为:温度115.00℃,时间3.87h,酸浓度1.00%,液料比16:1。在此条件下,L-阿拉伯糖得率可达到4.56%。 In this paper, single-factor experiments were designed according to the main factors affecting the acid-catalyzed hydrolysis, such as hydrolysis temperature (A), hydrolysis time (B), acid concentration (C) and liquid to liquid ratio (D) The yield of arabinose was the response value. The center combination design was adopted to optimize the acid-catalyzed hydrolysis process by response surface methodology. The second-order mathematical model was obtained and the optimum process was determined as follows: temperature 115.00 ℃, time 3.87h, acid concentration 1.00%, liquid material ratio of 16: 1. Under this condition, the yield of L-arabinose can reach 4.56%.
