The variation of proximate compositions, amino acids, carotenoids, chlorophyll, and total cyanide contents in cassava leaves was studied to identify the most suitable leaves for human consumption. The cassava leaves from 4 cultivars were analysed at 3 leaf positions as well as at 2 plant ages. The leaves of 'Rayong 5' cultivar from the middle position at 6 months after planting contained the highest crude protein, amino acids, carotenoids, and chlorophyll. The total cyanide content was high and therefore, an effective detoxification method is needed. Protein from the cassava leaves was rich in glutamine, aspartic acid, and leucine, but low in methionine and cysteine. Additionally, cassava leaves were found to be a rich source of carotenoids and chlorophyll. This study provided the evidences that cassava leaves can be an alternative source as protein supplement and for carotenoids and chlorophyll extraction and paves the way to valorise this abundant agricultural by-product.
研究了木薯叶中近似成分、氨基酸、类胡萝卜素、叶绿素和总氰化物含量的变化，以确定最适合人类食用的叶片。分析了 4 个品种的木薯叶在 3 个叶位和 2 个不同的生长阶段的情况。种植后 6 个月，来自‘Rayong 5’品种的中部叶片含有最高的粗蛋白、氨基酸、类胡萝卜素和叶绿素。总氰化物含量较高，因此需要一种有效的解毒方法。木薯叶中的蛋白质富含谷氨酰胺、天冬氨酸和亮氨酸，但蛋氨酸和半胱氨酸含量较低。此外，木薯叶是类胡萝卜素和叶绿素的丰富来源。本研究为木薯叶可作为蛋白质补充剂以及类胡萝卜素和叶绿素提取的替代来源提供了证据，并为充分利用这一丰富的农业副产品铺平了道路。
