中文摘要: 玛咖酰胺类化合物是新资源食品原料玛咖粉中的特征性成分。 为了富集玛咖中的玛咖酰胺类单体化合物,首 次采用酸碱反应去除脂肪酸类主要干扰杂质,并对提取工艺进行优化。结果表明,超声初提玛咖酰胺的最佳条件为:以 乙醚为提取溶剂,料液比 1 ∶ 30(g/mL),超声时间 30 min;酸碱反应的最佳条件为:氢氧化钠添加量 5.0 mL,反应温度50 ℃和酸碱反应时间 50 min。在最优条件下,提取物中的玛咖酰胺含量为 20.79 %,相对于 DBS 53/001-2015《食品安全 地方标准 玛咖干制品》中的提取方法,它的相对含量上升了 73.9 %。
Abstract:Macamides was the active marker compounds of maca powders. Macamides was gathered from maca powders through acid-base reaction firstly, which could remove the main impurities such as fatty acid and so on. Then extraction process was optimized. The preliminary results presented that the optimum conditions of super- sonic extraction of macamides as follows: the best extraction solvent was diethyl ether, ratio of material to sol- vent was 1 ∶ 30(g/mL)and time of extraction was 30 min; the optimal acid-base reaction conditions was that re- action temperature of 50 ℃, the volume of so dium hydroxide of 5.0 mL and reaction time of 50 min. Under opti- mized conditions, the content of the macamides in maca extract could reach to 20.79 %, compared with the ex- traction method in THE MACA DRY PRODUCTS QUALITY STANDARD(DBS 53/001-2015), it increased by 73.9 %.
