ABSTRACT This study examined the effects of chemical pre-milling treatment on the physico-chemical as well as pasting properties of Mucuna sloanei ‘ukpo’ flour. The seeds were treated with Distilled water, Citric Acid, Sodium bicarbonate, and Sodium Chloride solutions at various levels of concentration (1% 2.50%, 5% 7.5%, 10% w/v) before milling into flour. Proximate and functional properties of the flour were evaluated. Functional property analysis, of the Chemical treated flour showed t...

Developments on the Bioactive Compounds and Food Uses of the Tubers: Colocasia esculenta (L) Schott (Taro) and Xanthosoma sagittifolium (L) Schott (Tannia)

Two varieties of Cocoyam Colocasia esculenta (L) Schott (Taro) and Xanthosoma sagittifolium (L) Schott (Tannia) are experiencing renewed interest not only in Africa but also in the rest of the world. They are considered to be cheaper sources of carbohydrates than cereals or other bulbous crops because of their high calorie yield per hectare, low production costs, and relatively low susceptibility to insect and pest infestation. In addition to their nutritional benefits, they contain bioa...

Effect of Oven Drying Temperatures in Preserving African Breadfruit (Trecuila Africana)

ABSTRACT The study was designed to evaluate the effect of oven drying temperature in Preserving African Breadfruit (Trecuila africana). African breadfruit was sorted out, washed with clean water, parboiled for three mins to enable easy dehulling of the seed, dehulled using manual disc attraction mill, winowed and cleaned. The African breadfruit was subjected to different rates of drying temperature (50°c, 60°c and 70°c). Proximate, mineral, phytochemicals and sensory evaluation of the raw ...

Nutritional Quality And Physico-Chemical Properties Of The Seed And Oil Of Chinese Fan Palm

ABSTRACT The oil of the raw seeds of Livistona chinensis (Chinese fan palm) was extracted and its physico-chemical properties evaluated. The proximate composition and the anti-nutrients present in the pulp, raw seed, blanched (4, 6, and 8 minutes), cooked (20, 40 and 60 minutes) and the roasted (1100C for 5, 10 and 15 minutes) seeds were determined. An acute toxicity study was also carried out on the seed during which albino rats were differently fed the raw and also the cooked and roasted s...

Effect Of Exogeneous Enzyme Hydrolysis Of Soybean (Glycine Max) Cell-Wall Materials On The Chemical Properties Of Soymilk

ABSTRACT The effect of cell wall enzymes on the sugar composition of soymilk was investigated using High Performance Liquid Chromatography (HPLC) and UV/Visible spectrophotometer. Soymilk was extracted from wet milled soybean slurry from three different varieties of soybean (Samsoy1, Samsoy 2 and TGX). Different cell-wall degrading enzymes (glucanase, cellulase. arabanase, hemicellulase and xylanase) were applied to each batch of soybean slurry before extraction of soymilk. The enzymes which...

Assessment Of Nutritional Quality Of Market Samples Of Fruit Drinks In Owerri

ABSTRACT Nutritional quality of market samples of some fruit drinks were assessed through laboratory analysis. The assessment covered the determination of quality parameters of six brands of fruits drinks which include California brands of orange and pineapple drinks, orange and pineapple fruta drinks and 5 – alive orange and pineapple drinks. The assessment indices included the determination of proximate compositions, mineral composition and vitamin composition of the drinks. From the res...

Antinutritional And Physicochemical Properties Of Flours Blended From Selected Tropical Tubers And Processed Bambara Groundnut (Vigna Subterranean).

ABSTRACT Some selected tropical root and stem tubers (cassava, cocoyam, sweet potato and yam) were dried and processed into flours. The cassava tuber was processed into flour using the high quality grading method. Bambara groundnut was processed to obtain the conventional bambara groundnut flour, bambara groundnut cotyledon flour and the steamed bambara groundnut cotyledon flour. Composite flours were formulated using each of the root tubers and each of the bambara groundnut treatments in th...

Antimicrobial Activities And Preservative Potentials Of Some Plant Extracts In Minced Meat.

ABSTRACT The antimicrobial activities and preservative potentials of crude plant extracts of stem bark of Alstonia boonei, leaves of Euphorbia hirta and seeds of Moringa oleifera were studied. Soxhlet extraction method and cold ethanol extraction method were used for the extraction of the dried and ground plant samples. The well in agar diffusion method was used for the antibacterial screening at different concentrations of 25mg/ml, 50mg/ml, 100mg/ml and 200mg/ml on Eschericia coli, Bacillus...

Effect Of Okara And Detarium Microcarpum Incorporation On The Quality Of ‘Talia’ Produced From Wheat And Sorghum Flour Blends

ABSTRACT The effect of Okara and Detarium microcarpum seed flours on the quality of talia noddles produced from wheat and sorghum flour composites was investigated. Composites of wheat semolina/sorghum flour blended in ratio of 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 were prepared and evaluated for water absorption capacity, soluble solids and swelling capacity. Cold extruded talia produced from each flour composites dough was evaluated for cooking time, cooking losses and total organic ...

Physicochemical and Sensory Qualities of Complemenatry meal made from Sprouted and Unsprouted Sorghum Irish potato and groundnut

Weaning food was produced from the blends of sprouted and unsprouted sorghum–Irish potato, and groundnut flour. In the developed weaning foods, moisture content ranged from 8.44% to 12.70%, crude protein (7.40%–14.53%) crude ash (1.53%–1.77%), crude fiber (6.65%–6.88%), crude fat (3.31%–3.73%) and carbohydrate content (65.10%–69.15%). Sprouting and protein supplementation with groundnut improved the protein content of the formulated meals with values comparable to commercial sam...
