Abstract
This article presents the nutritional composition of seeds of four pink lotus varieties cultivated in Thua Thien Hue province including three high-quality local varieties and one variety of high-yield lotus from Dong Thap province. The results show that these lotus seeds have high nutritional values with the degree of main nutrients in 100 g of dry lotus seeds as follows: carbohydrate (58.8–62.3 g), protein (19.9–23.8 g), lipid (2.05–2.67 g), sugar (11–13.7g), main minerals (K: 1.32–1.46 g, Ca: 0.13–0.21 g, P: 0.60–0.76 g), catalase enzyme (0.26–0.42 U/mg protein), and vitamin C (0.01–0.04%). The amino acid content of dry lotus seeds is from 16.61 to 7.86 g/100 g. The local varieties have a higher value regarding all research indicators than the variety from Dong Thap. In addition, the amylose content, gel consistency, and birefringence endpoint temperature of Hue pink lotus varieties are higher than those of the high-yield lotus, giving them better sweetness, elasticity, and aromatic flavor.
