中文摘要: 采用远红外低温烘焙的方法对原料绿豆进行熟化处理,经感官评价后得出其适宜的处理条件为烘焙温度130 ℃,时间180 min。通过建立的高效液相色谱法(high performance liquid chromatography,HPLC)测定方法测得原料绿豆和低温烘焙绿豆中牡荆苷与异牡荆苷的含量分别为(0.044±0.002)%、(0.033±0.000 5)%和(0.047±0.002)%、(0.036±0.001)%。试验表明:低温烘焙加工熟化后的绿豆具有良好的感官特性,牡荆苷和异牡荆苷的含量未发生明显的变化,是适宜的绿豆干燥熟化加工方法。可见,在该条件下开发的绿豆冲调食品避免了高温条件对绿豆中活性成分的破坏,对开发全营养绿豆食品具有重要的意义。
Abstract:Far infrared low temperature baking method was used to mature the mung bean.After the sensory evaluation,the suitable treatment conditions were 130 °C and 180 min.HPLC method was established to determine the content of vitexin and isovitexin in mung bean and bakes was(0.044±0.002)%,(0.033±0.000 5)%,and (0.047±0.002)%and (0.036±0.001)%.The results showed that the mung bean of the low-temperature baking have good sensory characteristics and the content of vitexin and isovitexin has not changed significantly.The far infrared low temperature baking drying ripening is a suitable technics for mung bean.
