摘要
通过测定红棕象甲幼虫的氨基酸、脂肪酸、微量元素等基本营养成分的含量和抗氧化活性,并与其他常见食物进行对比,综合评价红棕象甲幼虫的营养功能活性.结果表明:红棕象甲幼虫中含有 42.73%的蛋白质,49.90%的脂肪和 1.55%的灰分;蛋白质中含有以酪氨酸(15.86%)为主的 17 种氨基酸;脂肪酸组成中以不饱和脂肪酸(58.03%)为主,其中油酸和亚油酸含量分别为 50.52%和 1.21%,n-6∶n-3 比例为 3.23;矿质元素中以钾、镁和钙的含量相对较高,同时还含有少量的锰、铁、铜和锌.红棕象甲幼虫水提物对 DPPH 和羟自由基清除能力相对较好,醇提物具有相对较好的亚铁离子螯合能力.研究结果为红棕象甲幼虫的资源化开发利用提供了数据和理论支撑.
Abstract
The nutritional and functional activities of Rhynchophorus ferrugineus larvae were comprehensively evaluated by determining the contents of fundamental nutrients such as amino acids,fatty acids,and trace elements and their antioxidant activities and comparing them with those of other common foods.The results showed that the R.ferrugineus larvae contained 42.73%protein,49.90%fat,and 1.55%ash;the protein contained 17 amino acids,primarily tyrosine(15.86%);the fatty acid composition was dominated by unsaturated fatty acids(58.03%),of which the contents of oleic acid and linoleic acid were 50.52%and 1.21%,respectively,and the n-6:n-3 ratio was 3.23;and the contents of potassium,magnesium,and calcium were relatively high in mineral elements and contained small amounts of manganese,iron,copper and zinc.In addition,the aqueous extract of R.ferrugineus larvae had relatively good scavenging ability for DPPH and hydroxyl radicals,and the alcoholic ex-tract had relatively good chelating ability for ferrous ions.The results of this study provide data and theoretical support for the resource development and utilization of R.ferrugineus larvae.
