The changes in nutrients during the germination of wheat, mung beans and chickpeas were investigated. Germination was performed under conditions commonly used in the household. The amount of water taken up during 4 days of germination varied from 159 g/100 g (chickpeas) to 450 g/100 g (mung beans). For all three seeds losses of dry matter and carbohydrates were observed. In wheat and mung beans, phytic acid was partially hydrolyzed. In mung beans, the total fat content decreased. Increases in the content of polyunsaturated fatty acids in wheat and of dietary fibre in wheat and mung beans were noted. At a constant level of crude protein, a measurable rise in limiting amino acids was observed in wheat and mung beans. Frequent watering during germination caused losses of Fe, between 9% and 21%, K (27% in chickpeas) and Cu (17% in chickpeas). Except for vitamin B6 in both legumes and vitamin B1 in chickpeas, accumulation of the vitamins under investigation (B1, B2, B6, C, E) was noted. Owing to these changes during germination, the nutritional value of the three seeds has been improved to various extents, most distinctly in wheat and least noticeably in chickpeas. Compared with other vegetables, sprouted seeds can be considered a valuable addition to the diet.
研究了小麦、绿豆和鹰嘴豆发芽过程中营养成分的变化。发芽过程是在家庭常用条件下进行的。在4天的发芽过程中,吸水量从159克/100克(鹰嘴豆)到450克/100克(绿豆)不等。对于所有三种种子,均观察到干物质和碳水化合物的损失。在小麦和绿豆中,植酸被部分水解。在绿豆中,总脂肪含量下降。注意到小麦中多不饱和脂肪酸含量增加,以及小麦和绿豆中膳食纤维含量增加。在粗蛋白水平恒定的情况下,观察到小麦和绿豆中限制性氨基酸有可测量的增加。发芽期间频繁浇水导致铁损失9%至21%、钾(鹰嘴豆中为27%)和铜(鹰嘴豆中为17%)。除了两种豆类中的维生素B6和鹰嘴豆中的维生素B1外,还观察到所研究的维生素(B1、B2、B6、C、E)有所积累。由于发芽过程中的这些变化,这三种种子的营养价值都有不同程度的提高,在小麦中最为明显,在鹰嘴豆中最不明显。与其他蔬菜相比,发芽种子可被视为饮食中的宝贵补充。
