The present investigation was aimed to study the effect of detoxification on the nutrients and antinutrients of wild apricot kernel followed by its hypocholesterolemic effect in male Wistar albino rats. The results revealed a non-significant (p > 0.05) effect of detoxification on the proximate composition except total carbohydrates and protein content. However, detoxification led to a significant (p < 0.05) decrease in L-ascorbic acid (76.82%), β-carotene (25.90%), dietary fiber constituents (10.51–28.92%), minerals (4.76–31.08%) and antinutritional factors (23.92–77.05%) (phenolics, tannins, trypsin inhibitor activity, saponins, phytic acid, alkaloids, flavonoids, oxalates) along with the complete removal (100%) of bitter and potentially toxic hydrocyanic acid (HCN). The quality parameters of kernel oil indicated no adverse effects of detoxification on free fatty acids, lipase activity, acid value and peroxide value, which remained well below the maximum permissible limit. Blood lipid profile demonstrated that the detoxified apricot kernel group exhibited significantly (p < 0.05) increased levels of HDL-cholesterol (48.79%) and triglycerides (15.09%), and decreased levels of total blood cholesterol (6.99%), LDL-C (22.95%) and VLDL-C (7.90%) compared to that of the raw (untreated) kernel group. Overall, it can be concluded that wild apricot kernel flour could be detoxified efficiently by employing a simple, safe, domestic and cost-effective method, which further has the potential for formulating protein supplements and value-added food products.

抗营养因子和野生杏仁的降胆固醇作用(山杏由于受解毒L.)

本研究旨在研究排毒对野生杏仁营养成分和抗营养成分的影响,然后研究其对雄性Wistar白化病大鼠的降胆固醇作用。结果表明,除总碳水化合物和蛋白质含量外,排毒对附近成分无显着影响(p > 0.05)。但是,排毒导致L值显着下降(p <0.05)-抗坏血酸(76.82%),β-胡萝卜素(25.90%),膳食纤维成分(10.51–28.92%),矿物质(4.76–31.08%)和抗营养因子(23.92–77.05%)(酚类,单宁酸,胰蛋白酶抑制剂活性,皂苷,植酸,生物碱,类黄酮,草酸盐),以及将苦味和潜在有毒氢氰酸(HCN)完全去除(100%)。籽仁油的质量参数表明解毒对游离脂肪酸,脂肪酶活性,酸值和过氧化物值无不利影响,但仍远低于最大允许极限。血脂谱证明排毒的杏仁组表现出明显的(p<0.05)与之相比,HDL-胆固醇(48.79%)和甘油三酸酯(15.09%)的水平增加,总血胆固醇(6.99%),LDL-C(22.95%)和VLDL-C(7.90%)的水平下降原始(未经处理的)内核组的数量。总的来说,可以得出结论,通过采用一种简单,安全,家用且具有成本效益的方法可以有效地对野生杏仁粉进行排毒,这进一步具有配制蛋白质补充剂和增值食品的潜力。
