Composition of seed and characteristics of oil from karingda [Citrullus lanatus (Thumb) Mansf]

Physicochemical Properties of Oil Extracts from <i>Sesamum Indicum</i> L. Seeds Grown in Jigawa State – Nigeria

“…The results of the oil content, iodine value, specific gravity determinations and other physicochemical analysis of the oil extracted from the Sesame seeds compared favourably with those reported by other workers (Abayeh et al, 1998;Ezeagu et al, 1998;Das et al, 2002;Fernando and Akujobi, 1987;Horwitz, 1980;Klein, 1994;Stebbins and Lance, 1980;York, 1979). The high percentage oil content of the seeds makes them viable for commercial extraction.…”

“…Thus, the oil will not attract high interest in the paint and coatings industry unless it undergoes dehydration before use (Abayeh et al, 1998). The values are comparable to iodine value of melon seed, 124.5 (Das et al, 2002) and 121.03 for African pear, Caryodes edulis (Ajiwe et al, 1997). On the other hand, the values obtained are higher than 53.4 to 101.5 reported as iodine values for some selected vegetable oils (cotton seed, melon seed and shea) marketed in former Sokoto State (Fernando and Akujobi, 1987) and other wild seed oil grown in Bauchi, Nigeria (Abayeh et al, 1998), but lower than 178.8 reported in Palm oil (Oshinowo, 1987).…”

“…Crude oil was extracted by the use of a soxhlet extractor with nhexane at 40 o C for 24 hours (Das et al, 2002). Analysis of saponification value, peroxide value, acid value, iodine value, specific gravity, oil content and cyanide test were carried out using the methods of AOAC (1990).…”

Physicochemical properties and fatty acid composition of crude and processed Adenopus breviflorus Benth seed oil

“…In addition, the high iodine value of the oils indicates that the oil contains more unsaturated fatty acid than saturated fatty acid since iodine value is a measure of the extent of unsaturation of fatty acid present in fats and oils (Nielsen, 2002). The iodine values are comparable to iodine value of 112.10 for Adenopus benth seed oil (Das et al, 2002) and 121.03 for Africa pear, Caryodes edulis (Ajiwe et al, 1997). On the other hand, the values obtained are higher than 83.50 reported as iodine value of Moringa oleifera seed oil (Ogbunugafor, 2011).…”

Morphological and allozyme variation in a collection of Cucumeropsis mannii Naudin (Cucurbitaceae) from Côte d'Ivoire

“…The indigenous edible-seeded cucurbits are classified into the minor crops. There are several species of cucurbit in tropical Africa and Asia, cultivated mainly for their oleaginous seeds that are important in the social and cultural life of several peoples (Badifu, 1993;Das et al, 2002;Enujiugha and Ayodele-Oni, 2003;Achu et al, 2005;Zoro Bi et al, 2005). Cucumeropsis mannii Naudin belonging to this category of crop, is one of the most widely distributed and consumed at both rural and urban levels in Sub-Saharan Africa.…”
