Physical properties and nutritional potentials of Indian roselle (Hibiscus Sabdariffa L) seeds

The physical and nutritional properties of Indian Roselle (Hibiscus sabdariffa L) seeds where studied. In India the Roselle seeds are not well known as such underutilized, the plants are cultivated and used mostly for their fiber, vegetables and calyces for making local drinks. The vast proportions of the seeds often go to waste as it is used mainly for the purpose of propagation. The seeds have been found to be a good source of lipid (23.80 %), proteins (38.06 %), a rich fiber source (19.87 %) and inorganic minerals such as calcium (Ca) 320.45 mg/100 g, magnesium (Mg) 464.36 mg/100 g, phosphorus (P) 590.14 mg/100 g, potassium (K) 1925.67 mg/100 g, iron (Fe) 11.45 mg/100 g, zinc (Zn) 17.43 mg/100 g and manganese (Mn) 7.57 mg/100 g , also containing significant percentages of bioactive components that could provide massive suitable substitute nutritionally as a cheap nutrients source especially in a vegetarian society as India and other parts of the world.
