| 中文摘要: |
| 为优化乳酸辅助提取菠萝皮果胶的工艺,在单因素实验的基础上,利用响应面法建立了菠萝皮果胶提取工艺的二次响应面方程。实验证实提取时间、乳酸浓度、液料比、提取温度对菠萝皮果胶提取率有不同的影响。结果表明,在实验范围内,各工艺条件对菠萝皮果胶提取率的影响大小顺序为:提取温度 > 乳酸浓度 > 提取时间 > 液料比。菠萝皮果胶提取的最佳工艺参数:提取时间96 min,乳酸浓度8.25%,液料比25 mL·g-1,提取温度74 ℃,在此条件下,菠萝皮果胶提取率达8.47%,与预测值相对误差为0.58%,验证了该模型的有效性,表明该提取工艺条件合理可行。 |
| 英文摘要: |
| To well-utilized pineapple peel pectin, lactic acid-assisted extraction was applied for its extraction from pineapple peel. The single factor experiment and response surface method were used to optimize the effect of processing parameters on extraction yield of pectin such as time, lactic acid concentration, ratio of liquid to material and temperature, the different factors had different effects on the extraction yield of pectin. The results showed that the effect order of four factors on the pectin yield was as follows: temperature, lactic acid concentration, time and ratio of liquid to material. And the optimal extraction conditions of pectin from pineapple peel were: time 96 min, lactic acid concentration 8.25%, ratio of liquid to material 25 mL·g-1, temperature 74 ℃. The yield of pectin could be up to 8.47% under the optimal extraction condition, the relative error was 0.58% compared with the predictive value, which illustrated the feasible model fitted well with the experimental data. It showed that the conditions were reasonable and feasible. |
