“…A number of factors such as variety, location and environmental conditions affect the nutritional composition (amounts of protein, oil, carbohydrates and dietary fiber) of roselle seeds (Rao, 1996;Abu-Tarbouch et al, 1997;El-Adawy and and Khalil, 1994;Hainida et al, 2008a,b). Apart from its oil content, roselle seeds are also utilized as a promising alternative source of plant proteins that could be used in human, livestock, fisheries and other animal nutrition perspectives (AlWandawi et al, 1984;Husseina et al, 2010;Ibrahim et al, 2011;Tounkara et al, 2013Tounkara et al, , 2014. Boiled roselle seeds have a good amount of protein which is analogous to casein (Halimatul et al, 2007).…”

“…The crude fibre content was found to be 11.16±0.58%. The value obtained is lower than 13.87±0.67% reported for dried Hibiscus seed by Tounkara et al [41]. Fibre helps in the maintenance of human health and has been known to reduce cholesterol level, aids digestion and delays emptiness of the stomach [42].…”

Background: Soup condiments are edible food items which are added to dishes, used as thickeners for soup and also as food supplements such as sauce that is added to food to impact specific flavours. They are abundantly produced in Nigeria especially in North-Western part of the country. Aims: The aim of this research was to determine the proximate composition and parasitic contamination of Hibiscus sabdariffa seed cake (Roselle seed cake): a soup condiment produced by North-Western Community, Nigeria. Study Design: Samples were purchased and collected at random from the markets of different places in the study areas, aseptically placed into polythene bags and labelled correctly. Place and Duration of Study: The study was conducted in Zuru and Sakaba Local Government Areas of Kebbi State, North-Western Nigeria. Methodology: The proximate analysis carried out include: moisture determination, ash determination, determination of crude protein, lipid determination, fibre determination and carbohydrate estimation by difference. The protozoa present in the samples were identified by direct microscopy. Results: The proximate composition of Hibiscus sabdariffa seed cake in the study areas had a very high level of carbohydrate content (52.44±1.03%), followed by the moisture content (15.43±0.10%), lipid content (12.00±0.50%), fibre content (11.16±0.58%), ash content (7.80±0.05%) and crude protein content (1.16±0.13%) which was the lowest. The highest prevalence rate of the identified protozoa was recorded in Entamoeba histolytica 2(50.0%) followed by Giardia lamblia 1(25.0%) in Zuru Local Government Area. No protozoa was seen in Zuru sample 0(0.0%). In Dabai sample, Giardia lamblia was seen 1(25.0%). While in Bedi sample, Entamoeba histolytica 2(50.0%) was seen which was the most prevalent. However, in Sakaba Local Government Area, a total of nine protozoa was seen and all were Entamoeba histolytica. Dirin-Daji sample showed 1(11.1%), Doka 2(22.2%), Dankolo 2(22.2%), Janbirni 1(11.1%), Laraba 1(11.1%) and Makuku 2(22.2%) respectively. Conclusion: It can be concluded that the available carbohydrate and moisture contents were higher than other parameters and the local soup condiments were heavily contaminated with protozoa and Entamoeba histolytica had the highest prevalence which can cause serious food-borne diseases in humans in the study areas. Finally, the need to apply good manufacturing practices in processing the condiments in the study areas and North-Western Nigerian Community as a whole is highly recommended.

Aim: The purpose of this study was to evaluate the functional properties of Roselle seed protein isolates and its hydrolysates. Place and Duration of Study: The Roselle seeds were collected in Koutiala (Mali), in November 2018. All analysis were conducted in the Faculty of Sciences and Technics, particularly in the Laboratory of Plant and Food Biochemistry and Biotechnology from January to June 2019. Methodology: The effect of enzymatic hydrolysis on the functional properties of Roselle seed protein (RSP) was investigated. Defatted Roselle seed flour was used to extract the protein isolates. The protein was digested for 2 hours and 3 hours using pepsin followed by pancreatin. Results: The 2 hours and 3 hours Roselle seed protein hydrolysates (RSPH2, RSPH3) compare to RSPI, exhibited a good foaming capacity of 300, 315 and 165% respectively. The water holding capacity (WHC) of the RSPI, RSPH2 and the RSPH3 were 2, 2.5 and 2.2 ml/g respectively. The oil holding capacity ranged from 5.75 to 5.32 ml/g, the emulsifying capacity of the RSPH2 was higher than that of the RSPH3 and the RSPI, 105, 97 and 82 ml/g respectively. Conclusion: The ability of pepsin and pancreatin hydrolysates to be functional is primarily due to their soluble peptide content. The samples have good functional properties. These results proposed that pepsin and pancreatin hydrolysates could be useful as whole or partial replacement of high-price materials such as egg albumen and casein.
