Abstract:

The study investigated the potential production of fried chips from bitter yam (Dioscorea dumentorum) as well as the evaluation of quality characteristics of the chips. Yellow and white bitter yam and sweet potato (control) obtained from a local yam farmer were respectively processed into fried chips while the chips were subsequently subjected to analysis. The results showed that the proximate composition of fried bitter yam ranged as follows: moisture content (5.32 – 6.04), fat (28.93 – 29.41), ash (1.66 – 1.82), fibre (4.45 – 7.38), protein (2.44 – 3.32) and carbohydrate (58.71 – 61.85 g/100

Starches were isolated from cocoyam (Xanthosoma sagittifollium), white yam (Dioscorea rotundata) and bitter yam (Dioscorea dumentorum). Starch modification was carried out using acetic anhydride and phthalic anhydride. The native and modified starches were characterized using Fourier Transformed Infra-red Spectroscopy (FTIR) for identification of the functional groups. Functional properties such as water absorption capacities, oil absorption capacity, swelling power, solubility, gelation temperature, least gelation capacity, amylose content and pH were determined using standard procedures.

<strong>ABSTRACT</strong> The determination of stress relaxation of three varieties of Benue state grown yams was carried out using the universal testing machine to study the behaviour of the named varieties; bitter yam, water yam and white yam tubers under loading. The yam tubers were cut into cubes of 2700mm<sup>3 </sup>and the stress relaxation was observed under the application of constant stress and constant strain. It was observed that the stress relaxation across the three varieties of yams ranged from 0.0370460-0.0983780 (Mpa) with water yam (Dioscoreaalata) having the highest value of

Starch was extracted from bitter yam (Dioscorea dumetorum) and subsequently modified through esterification (succinylation) and microwave treatment. The functional properties of the starches were then examined. Proximate composition analysis showed that, after modification, the succinylated (OSABS) and microwavetreated (MTBS) starches exhibited lower moisture content but higher levels of protein, ash, crude fiber, and fat compared to the untreated bitter yam starch (UBS). Both modifications substantially improved the swelling power and solubility profile of OSABS and MTBS at 80 °C. SEM microgr

AbstractThere exists general consensus in the archaeological literature that bitter manioc was a staple crop in precontact agricultural systems in the lowlands of South America. This view is based upon the indirect evidence derived from archaeological ceramic and lithic assemblages rather than archaeobotanical evidence, the preserved remains of bitter manioc itself. Studies of microlithic “manioc” grater flakes from Pozo Azul Norte-1, a site located in the middle Orinoco valley of Venezuela, reveal a much more complex function of these artifacts involving the processing of several starchy root

An investigation was carried out during 2012-2013 in Puri district of Odisha to study the composition, structure and role of coconut (Cocos nucifera L.) based farming in 15 different holding sizes, i.e. 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4 and 1.5 acre.

The smaller holdings were found close to houses as homegardens and comparatively larger holdings were found little away from the houses.

Abstract:

<p>Coffee prepared via gravity-drip filtration is an alternative to obtain varied sensorial profiles and determine the acidity, bitterness, and body thereof. In the present study, the retention of certain bioactive components was determined, as was the antioxidant activity and cup profiles for coffee beverages prepared by way of seven different gravity-drip filtration methods. The methods which registered the greatest bioactive metabolite retention were the Vietnamese, Clever, and RS 16 methods. The greatest hydroxycinnamic acid content was obtained with the Clever, Yama, Vietnamese, and

Abstract:

Meat tenderness and flavor are essential characteristics for consumer satisfaction. These parameters are influenced by several aspects, such as animal species and proteolytic enzyme activity that occurs during post- mortem aging. This work aimed to evaluate the evolution of the proteolytic degradation on Longissimus dorsi muscle in male buffalo (B), yak (Y), and Maremmana beef breed (M) of about 16 months old during the pre-rigor and post-rigor period. Muscle samples were stored at 3 °C and sampled at 3, 6, 24, 72 h, 7, and 14 days after slaughtering five animals for each species. All the samp

Abstract:

The roasting of food is one of the oldest food preparation and preservation technologies. Although roasted foods have been associated with potential health hazards, this processing method is still used in many foods. This study was carried out to ascertain the health risks of ingesting white (Dioscorea rotundata), and bitter yam (Dioscorea dumetorum) roasted with firewood, charcoal, and charcoal augmented with PET bottles. The PAH content in all the roasted yam samples was identified and analyzed using gas chromatography-mass spectroscopy (GC-MS). A total of 8 PAHs were identified in both yam

Abstract:

The use of plant extracts to induce resistance against pathogens has shown to be a promising alternative in the management of plant diseases. The objective was to evaluate the potential of ethanolic extract of Mormodica charantia on management of the Curvularia eragrostidis and enzyme activation involved on defense responses in yam (Dioscorea alata). The isolate of C. eragrostidis was obtained from leaves of yam with symptoms. Mycelial growth and sporulation were evaluated. The treatments were: extract of Momordica charantia 10, 100, 500 and 1000 ppm, acibenzolar-S-methyl (200 mg.L-1), fungici

Abstract:

AbstractThis study examined how microwave power loading (300–600 W) affected Dioscorea bulbifera (BY) slice drying, colorimetric values, moisture diffusion, textural, and rehydration properties. Drying time was reduced from 100 to 40 min with increased microwave power from 300 to 600 W. Drying rate and moisture diffusivity (4.948 × 10−9–1.262 × 10−8 m2/s) enhanced with microwave power and was observed falling rate drying. The initial and final moisture content of BY slices were 87% (w.b.) and 4.5% (w.b.), respectively. The activation energy for BY slices was 9.6 W/g. To illustrate the drying a
