中文摘要: 以云黑青稞为材料,通过提取其多酚化合物,以亚硝酸盐清除率为指标,在单因素试验基础上利用响应面优化确定青稞多酚清除亚硝酸盐的工艺条件。在此工艺条件下,进行云南省主要小杂粮多酚对亚硝酸盐清除率作用的比较研究。结果表明:青稞多酚清除亚硝酸盐的最佳工艺条件为多酚用量1.1 mL,反应温度59℃,反应时间34 min,在此条件下亚硝酸盐的清除率为64.04%。10种小杂粮中多酚对亚硝酸盐清除范围为23.90%~86.24%,其中黑米(86.24±1.00)%和紫米(83.59±1.53)%的清除作用显著高于其它小杂粮(p<0.05),藜麦(23.90±2.42)%的清除作用显著低于其它小杂粮(p<0.05),研究结果为小杂粮的开发利用提供了科学依据,也为小杂粮的精深加工提供新思路。
Abstract:The nitrite scavenging optimal conditions of polyphenols from Yunhei hulless barley were investigated by response surface methodology design on the basis of single factor experiments.Under the optimal conditions,the effects of major small grains in Yunnan on nitrite scavenging rate were compared.The optimal conditions were found to be:the amount of polyphenols 1.1 mL,reaction temperature 59℃,reaction time 34 min,the nitrite scavenging rate was 64.04%.The nitrite scavenging rate range of polyphenols from small grains was 23.90%-86.24%,the scavenging abilities of black rice (86.24±1.00)%and purple rice (83.59±1.53)%were significantly higher than other small grain (p<0.05),quinoa (23.90±2.42)%was significantly lower than other small grain (p<0.05).The results provide a scientific basis for development and utilization of small grains,and also provide new ideas for the intensive processing of small grains.
