Organic Hibiscus sabdariffa / Roselle Seeds: Non-GMO, India Sorrel, Organic Seed Packets
The fleshy red calyces of Hibiscus sabdariffa are dried for tea and also used as food. Homegrown calyces are far superior to anything that can be found in the marketplace. It is considered a subtropical/tropical plant, so it needs heat to bear usable herbage.
The seeds are said to be diuretic and tonic in action.Roselle calyces and seeds is a rich source of protein and macronutrients such as K, Na and Mg. Seeds are better source of micronutrients contents (Cu, Fe and Mn). Accordingly, Roselle could be used as supplement food or diet enrichment especially in the low protein diets. Since some cereals flours commonly consumed are deficient in some mineral elements such as calcium, the fortification of flours with Roselle seed flour might improve their dietary properties.
Two varieties of Mesta (Hibiscus sabdariffa) seeds were analyzed for their proximal composition. Their protein (18.8-22.3%), fat (19.1-22.8%) and dietary fiber (39.5-42.6%) content were found to be high. The seeds were found to be a good source of minerals like phosphorus, magnesium and calcium. Their lysine and tryptophan contents were also high. Sulphur containing amino acids were limiting in this seed protein and the chemical score of Mesta seed protein was 40 and 57 for AMV-2 and Bhimili-1 varieties respectively. Mesta seed oil is rich in unsaturated fatty acids (70%), of which linoleic acid constituted 44%.
Weanling rats were fed with 10% Mesta seed protein before and after cooking for 4 weeks. Food intake of animals receiving raw Mesta seed diets was significantly lower than those receiving cooked Mesta seed diets as well as the casein control diet. Protein and dry matter digestibility's of raw and cooked Mesta seed diets were lower than that of casein control diet. Cooking improved the food intake, gain in body weight, dry matte and protein digestibility of Mesta seed diets. PER and NPU of cooked Mesta seed diets were significantly higher than the corresponding raw diets. These results indicate that cooked Mesta seed protein is of relatively good quality.
