“…A positive correlation was observed between LDL-C and TC. These results were similar to those obtained by Hainida et al (2008) who observed significant negative correlations between HDL-C with TC and LDL-C and a positive correlation between LDL-C and TC after inclusion of 50 g/kg and 150 g/kg of dried roselle seeds in the diet of rats. Since HDL-C is negatively correlated to coronary heart diseases, consumption of roselle seeds might have a cardio protective effect.…”

“…One of such feed ingredient that can be used as protein supplement with little or no cost is Hibiscus sabdariffa L. (roselle) seeds. Roselle seeds cultivated in many countries such as Egypt, India, Mali, Malaysia, Nigeria, and Sudan have been found to contain high amount of protein, dietary fiber, lipids, and minerals (Samy, 1980;Rao, 1996;Fatoumata et al, 2011;Hainida et al, 2008;Balogun and Olatidoye, 2012; Abu El Gasim et al, 2008). It is known that many factors can affect the chemical composition of food among which is the geographic area.…”

Abstract:The chemical composition and protein quality of raw, boiled, toasted and soak-toasted roselle seeds harvested in the North (area I) and West (area II) regions of Cameroon were investigated in this study. To conduct the growth and nitrogen balance study, sixty albinos wistar rats of 21 to 25 days separated into ten groups of six rats/group were used and fed for fourteen days with 10% (w/w) isoproteinous experimental diets. These groups were Protein free diet (D0), egg white-standard reference protein diet (D1) and raw (D2I, D2II), boiled (D3I, D3II), toasted (D4I, D4II) and soak-toasted (D5II, D6II) roselle seed diets. Transaminases, serum creatinine, haematocrit, lipid parameters were also assessed in the rats. Results showed that crude protein, lipid, fiber and ash content of seed samples ranged respectively from 22 to 26, 18 to 22, 18 to 23 and 4.3 to 6.4%. The contents of Ca, Mg, K, Na, P, Fe and Zn were ranged from 1054 to 1920, 1670 to 2083, 26.45 to 272.7, 14 to 22, 10.58 to 90.78, 137.3 to 169.22 and 10.13 to 70.11 mg/kg respectively. Food intake was higher (P<0.05) for groups D1, D3I and D3II than for others groups. The rats fed with reference diet followed by boiled seed diets had the highest (P<0.05) weight gained, protein efficiency ratio (PER), net protein ratio (NPR), feed efficiency (FE), efficiency of food utilization (EFU) and true digestibility (TD). Aspartate aminotransferase and alanine aminotranferase were highest (p<0.05) in the rats fed raw roselle seeds. Compared to reference diet, the total cholesterol (TC), triglycerides (TG) and LDL-C of rats fed with diet D5II decreased while the HDL-C did not show any significant changes in these rats (p˃0.05). These findings show that roselle seeds cultivated in Cameroon have important amount of macronutrients and minerals. Proteins of roselle seeds are of good quality especially from the boiled seeds and are not influenced by the agro ecological region. Consumption of roselle seeds might be beneficial for cardio protective effect and no toxicity was observed as far as transaminases are concerned except that for the raw seeds which showed significant hepatotoxicity.

“…High amount of crude fibre (24.7 %) implied that the roselle seed could be considered as a good source of dietary fibre. Hainida et al (2008) indicated that roselle seed contained a balance proportion of soluble and insoluble fraction of dietary fibre. The total dietary fibre of the roselle seeds was within the acceptable range, with soluble and insoluble fibre ratios ranging from 1.2 to 3.3.…”

Roselle (Hibiscus sabdariffa L.) seed is a valuable food resource as it has an excellent source of dietary fibre. Therefore, this study examined the functional properties of roselle seeds. Replacement of cookie flour with roselle seed powder at levels of 0-30 % was investigated for its effect on functional and nutritional properties of cookies. Among the four formulations cookies, the most preferred by panelists was 20 % roselle seed powder cookie (F3), followed by 10 % roselle seed powder cookie (F2) and 30 % roselle seed powder cookie (F4). The least preferred formulation among all was control cookie (F1). Cookie with 20 % roselle seed powder added showed higher content of total dietary fibre (5.6 g/100 g) as compared with control cookie (0.90 g/100 g). Besides that, cookies incorporated with roselle seed powder exhibited improved antioxidant properties. Thus, roselle seed powder can be used as a dietary fibre source and developed as a functional ingredient in food products.

“…Haematinic activity Agbor et al, 2005 12. Cholesterol lowering effect Hainida et al, 2008b detected to be responsible for the antioxidant effect (Bako et al, 2009). In another investigation, the roselle seeds were found to have the potential to be used as food antioxidants where the seed methanol extract showed a positive correlation between phenolic content and antioxidant activity (Mohd-Esa et al, 2010).…”

“…Kenaf seeds were also observed to have anti-leukemic property , hydrolytic enzyme activity (Amma et al, 1977) and haematinic activity (Agbor et al, 2005). The defatted dried roselle seed powder was found to reduce total cholesterol and low density lipoprotein (LDL) in hyper-cholesterolemic rats and useful for human consumption (Hainida et al, 2008b). The seeds of kenaf and roselle also have diverse nutritional functions and could be utilized as an important non-conventional natural resources for production of functional foods.…”
