| 中文摘要: |
| 为了研究低温等离子体对荞麦的杀菌效果，确定最佳杀菌工艺参数，以甜荞麦为原料，
在单因素试验基础上，以处理时间和电压为因素，杀菌量和色差ΔE为评价指标，进行响应面中心
组合试验，分析因子间交互作用，建立荞麦杀菌量和色差的回归模型。利用遗传算法进行综合优
化，得出最佳杀菌工艺参数。结果表明低温等离子体对荞麦杀菌的最佳工艺参数为处理电压
54 kV，处理时间 48 min。在该条件下，菌落总数为 2.64 lg（CFU/g），色差 ΔE 为 1.83，多酚含量为
26.22 mg/g。低温等离子体技术可用于荞麦杀菌。 |
| 英文摘要: |
| The bactericidal effect of low temperature plasma on buckwheat was studied and the optimal sterilization param‑
eters were determined, which provided a theoretical basis for plasma technology for buckwheat sterilization. The common
buckwheat was used as the raw material. On the basis of single factor experiment, the treatment time and voltage were taken
as the factors, the sterilization amount and the color difference ΔE were used as the evaluation indexes, and then the re‑
sponse surface center combination test was carried out to analyze the interaction between the factors to establish the regres‑
sion model of sterilization amount and color difference of buckwheat. The genetic algorithm was used for synthetic optimiza‑
tion to obtain the optimum sterilization process parameters. The results showed that the optimum process parameters for low
temperature plasma sterilization of buckwheat were processing voltage 54kV and processing time 48min. Under such condi‑
tions, aerobic bacterial count was 2.64 lg (CFU/g), the color difference ΔE was 1.83, and the polyphenol content was
26.22 mg/g. Low temperature plasma technology can be used for buckwheat sterilization. |
