“…The highest content of any elements in these two materials was K, between 693 mg/100 g (tenera) and 751 mg/100 g (clonal). The result obtained in this study is slightly higher than that of Akpanabiatu et al (2001), where the K level of palm kernel was 277-660 mg/100 g dry matter. Palm kernel is a good source of dietary potassium.…”

“…Cloning of oil palm is carried out by inducing somatic embryogenesis on calli derived from various tissue sources (Jouannic et al, 2005). In future, clonal palms are expected to replace seed-derived planting material on a commercial scale (Abdullah, Zainal, Li, Beng, & Lee, 2005 A few studies have evaluated the chemical and nutritional values of oil palm (Akpanabiatu, Ekpa, Mauro, & Rizzo, 2001;Bora, Rocha, Narain, Moreira-Monteiro, & Moreira, 2003). However, little is known about the nutritional composition of oil palm planted in Malaysia, in particular the seed-derived and clonal palms of the tenera hybrids.…”

a b s t r a c tNutritive information about oil palm kernel is scarce, especially on the composition of sugars and watersoluble vitamins. This study aims to evaluate both tenera and clonal materials for their proximate composition, fatty acid profile, amino acid composition, sugar, mineral and water-soluble vitamin contents. The tenera material had a higher moisture, fat and fibre content as compared to the clonal material, whereas protein, carbohydrate and ash content were higher in the clonal material. The major fatty acid constituents in palm kernel oil were lauric acid, myristic acid and oleic acid. The palm kernel proteins were deficient in lysine and tryptophan but rich in glutamic acid, arginine and aspartic acid. Sucrose was the most abundant sugar in palm kernel. The mineral analysis of the samples showed high levels of potassium, phosphorus, magnesium, calcium and manganese, while niacin was the water-soluble vitamin present at the highest concentrations in palm kernel.

“…The crude protein contents in fresh oil samples were low but increased under room temperature, ambient temperature and refrigeration. Moreover, Akpanabiatu et al 11 reported that the tenera variety is richer in fat, ash and organic matter than the dura while the dura is richer in crude protein and fiber.…”

Examination of the palm oil from dura and tenera varieties of the oil palm (Elaeis guineensis) Jacquin for growth of microorganisms (fungi and bacteria), revealed that tenera was more stable to bacteria and fungal deterioration while dura was less biostable. Determination of the chemical composition of the palm oil types revealed that crude protein contents of the fresh oil samples which ranged from 0.037 to 0.066% were lower than those kept under different conditions. A tenera oil sample (80S, sample 8) had the highest free fatty acid (14.76%) while a dura oil sample (10 OJ, sample 10) had the lowest (4.46%). The peroxide values (PV) of the fresh oil sample were low (0.00 -10.40mEq/kg). The iodine values of the fresh oil samples were lower (23.57 -48.95) than those kept under different conditions (40.32 -70.43). Palm oils should not be stored for a long time because of deterioration.

“…Seeds of castor, coconut, dikanut, groundnut, melon, oil bean, palm kernel, soybean, vigna and phaseolus beans cultivars and a wide variety of seeds in the Leguminosae family are used in the preparation of diets (Onyeike and Acheru, 2002;Akpanabiatu et al, 2001;Onwuliri and Obu, 2002;Onweluzo et al, 1994). Cereals and legumes in the developing countries supply the energy and vegetable proteins requirement of both humans and animals.…”

Afzelia africana seeds were obtained from three locations, Abakaliki, Enugu and Nsukka, all in the Eastern part of Nigeria and de-hulled. The seed oil was extracted with (40 -60°C) petroleum ether and the oil was separated from the solvent using a rotary evaporator. Result of analysis shows that the acid value, saponification value, specific gravity, free fatty acid and refractive index of the oil samples were lowest for the samples obtained from Nsukka. The average moisture content of the seeds from the various locations was 5.56 ± ± ± ± 0.5%. The crude protein (26.44%) and oil content (33.32%) did not vary significantly with location or environment. The various oils were found to contain no less than 0.60 mg/100 g of oxalate, 0.70 mg/kg of phytate and neither tannins or cyanogenic glycosides. This paper empirically highlights the possible industrial applications as well as the safety of the seed oil.
