Antioxidant Activity and Nutritional Value of Roselle Seeds Flour

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

“…On the other hand, foaming capacity decreased significantly (P < 0.05) from 16% to 12% at 24 h germination but increased to 14% by 48 h, although this was still lower than the control. Values observed here are higher than those (8–10%) reported in a previous study which reported contrarily that germination increased foaming capacity [ 64 ]. The reduction in foaming capacity may be linked to modification of macromolecules during germination which may have resulted in denaturation and diminution of protein, thereby decreasing foaming capacity [ 15 ].…”

“…The rheological behaviour to ascertain the baking potential of wheat: germinated defatted sorrel seed flour blends as presented in Table 3 revealed that dough extensibility significantly decreased (p < 0.05) from 4.78 cm to 1.19 cm with increase in germinated defatted sorrel seed flour inclusion, while up to 20% sorrel seed inclusion resulted in null extensibility [ 64 ]. reported similar reduction in the extensibility of wheat flour supplemented with sprouted and decorticated sorrel seed flour.…”

“…[ 64 ] revealed that the enhancement of 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) scavenging potential of germinated sorrel seed extract could be harnessed in the production of value-added functional wheat-based foods that would provide both nutritional and health benefits. Furthermore [ 14 ], review on use of germinated legumes in composite bread making recommended the addition of flour from germinated seeds due to improvement in the nutritional and quality characteristics of the composite bread and rheological properties of the dough [ 24 , 44 , 98 ].…”

Assessing the Viability of Incorporating Sunflower Meal and Roselle Seed Meal as Unconventional Protein Sources in the Diets of Japanese Quails on Growth Performance, Carcass Characteristics, Serum Metabolites, Gene Expression, and Economic Efficienc

“…Additionally, some researchers have discovered that volatile oils in quails and broilers have an effect that promotes growth [63][64][65][66]. Roselle seed meal is nutrient-dense, being high in vitamin C, polyphenols, carotenoids, certain minerals, essential oils, and good fats [38,67]. Additionally, because of the high concentration of phenolic chemicals, it can act as a natural antioxidant.…”
