Nutrient composition of Dioclea reflexa seed : An underutilized edible legume
Abstract
The nutrient composition of dehusked Dioclea reflexa seed was studied. Results of proximate composition indicated a low moisture content (10.02 ± 0.27%) and high crude protein content (44.43 ± 0.45%). Ash, crude fat, crude fibre and carbohydrate content were 3.07 ± 0.05, 1459 ± 0.36, 0.98 ± 0.02 and 26.91 ± 0.18% respectively. Nutritionally valuable mineral analysis showed that D. reflexa is rich in potassium and phosphorus (496.20 ± 0.50 and 420.40 ± 0.20 mg/100 g respectively), and very low in copper and manganese (1.45 ± 0.04 and 1.64 ± 0.02 mg/100 g respectively). Eighteen amino acids were detected in varying concentration in the seeds, and among the essential amino acid assayed, leucine, with a chemical score of 81.14%, appeared to be the most limiting as others had scores above 100%, all compared with the NRC reference protein pattern. Three toxic substances were determined: phytic acid was 318.40 ± 0.30 mg/100 g; tannin 151.80 ± 0.20 mg/100 g; and hydrocyanic acid 2.10 ± 0.05 mg/100 g. D. reflexa is therefore a cheap source of animal nutrients which has been hitherto underutilized.

The potential of Pterygota macrocarpa to serve as a raw material source for industrial applications, domestic consumption, and animal feedstock formulation to reduce the overburden of few seed was assessed by this study. Two seed forms; whole and dehulled seeds, were analyzed for proximate composition, minerals contents, and anti-nutrient properties. Extracted seed-oils were characterized. The results indicate that the seed is a potential source of oil suitable for industrial applications while ...

Adult (ADS) and larva stages of palm weevil Rhynchophorus phoenicis were analyzed for their nutritional potentials using proximate and mineral contents as indices. The early larva stage (ELS) contains the highest moisture content of 11.94% while ADS has the least value of 4.79%. The late larva stage (LLS) has the highest protein content of 10.51% while ADS contains 8.43%. Ash content is highest in ELS with a value of 2.37% and lowest in ADS with a value of 1.43%. ELS and LLS have the highest (22...

Abstract Fatty acid composition and proximate analysis of eight terricolous insects namely dung beetle ( Copris nevinsoni Waterhouse), short tailed cricket ( Brachytrupes portentosus Lichtenstein), june beetle ( Holotrichia sp.), queen caste ( Oecophylla smaragdina Fabricius), weaver ant ( Oecophylla smaragdina Fabricius), termite ( Termes sp.), longan stink bug ( Tessaratoma papillosa ), cicada ( Meimuna opalifera Walker) were determined. Polyunsaturated fatty acid (PUFA) was the most predomina...

Determination of the proximate, nutritionally valuable minerals and anti-nutrient compositions in larvae of Cirina forda (W) showed that they contained high levels of protein, (55.50%±1.20%) with ash, moisture, fat, and carbohydrate levels being (10.26%±0.01%), (10.85%±0.38%), (4.68%±0.01%) and (18.70%±0.84%) respectively. Fibre was not detected. Protein solubility was higher in alkaline media than in acidic media while the isoelectric points were pH 4, 6 and 9 indicating that C. forda may be us...

The study aimed at exploring the anti-diabetic effect of the seed flour of Dioclea reflexa on alloxaninduced diabetic rats. Thirty Wistar rats of both sexes were exposed to respective doses of the seed flour and the standardized drugs (Gliclazide 6.1 mg/kd body weight and Metformin 60 mg/kg body weight) according to the group specifications. The seed flour at a dose of 2 g/kg body weight per oral once daily was found to be more effective than any of the standard drugs with which it was compared....

Proximate composition, mineral content and functional properties of the flour obtained from larvae of Cirina forda were evaluated. The proximate analysis revealed the crude protein to be 20.0 ± 0.2%, crude fat 12.5 ± 0.4%, moisture 4.5 ± 0.1%, ash 8.7 ± 0.1% and total carbohydrate 54.3 ± 0.2%. The mineral evaluation in mg/100g dry weight showed K (47.6 ± 0.1) > P (45.9 ± 0.6) > Na (44.4 ± 0.1) > Mg (43.8 ± 0.4) > Zn (24.2±0.2) > Ca (12.9 ±0.2) > Fe (1.3). Cu and Mn were not detected. The functio...

5 ABSTRACT: The objective of this research was to assess the proximate composition and selected functional properties of soft wheat flour. The commercially available soft wheat flour was purchased from local suppliers at Kajetia market in Kumasi-Ghana. The flour were cleaned of foreign materials and sieved through 75 μm. The flours were packaged in air-tight plastic containers prior to analyses. The flours were analyzed for their proximate composition. The flour functional properties were determ...
