A study on the use of sorrel seed flour (Hibiscus sabdariffa) for improving functionality of wheat flour bread.

Bread presents one of the easiest opportunities as a food vehicle for delivery of nutritional and health-promoting benefits to large segments of the world population. However, its low nutritional status due to lack of balance of essential amino acids and inadequate macro- and micronutrients has necessitated recent interest in the development of high-protein hybrid breads (HPHB). Sorrel seed, an underutilized, neglected protein-rich seed holds promising nutritional and antioxidant potentials as source of good quality protein, dietary fibre and bioactive compounds.
