The objective of this research endeavor was to enhance the quality and storability Dioscorea bulbifera through investigation effects pre-treatment (soaking) different dehydration temperatures (50, 60, 70°C) on its mass transfer, color kinetics, texture, microstructure, rehydration properties. Ten drying four-color kinetics models were employed describe behavior changes. process demonstrated a falling rate, with reduced time (from 960 540 min) as convective temperature increased from 50 70°C. Moisture diffusivity increasing hot air (4.15838 ×10-10 – 1.03114 ×10-09 m2/s), activation energy determined 41.82 kJ/mol. Slices dried at 70 °C exhibited higher change than those °C. modified model fitted best parameters, followed by fraction model. 60°C showed lower hardness (34.73 N) porosity (27.03%) compared 50°C (49.33 N 19.82%) 70°C (40.16 21.90%) temperature. Microstructure, moisture diffusion, texture closely linked content. Boiling potassium metabisulfite significantly affected yam slices' rate texture. MATLAB analysis provided detailed pore information for each air-dried sample, correlating characteristics. This offers substantial industrial significance providing methods products' quality, shelf-life enhancement, further exploration starch extraction recovery valuable bioactive compounds.

Abstract This paper reviews and analyzes key features from cassava breeding at the International Center for Tropical Agriculture (CIAT) over 50 years draws lessons public efforts broadly. The team, jointly with national program partners private processing sector, defined objectives guiding business plans. These have evolved through decades currently focus on four global product profiles. recurrent selection method also included innovations such as estimation of phenotypic values, increasing number locations in first stage agronomic evaluations, gradual reduction duration cycles (including rapid cycling high-heritability traits), development protocols induction flowering, introduction genome-wide predictions. impact depends significantly type target markets.

Demand-led breeding strategies are gaining importance in public sector globally. While borrowing approaches from the private sector, programs remain mainly focused on food security and social impact related outcomes. This necessitates information specific user groups their preferences to build targeted customer product profiles for informed decisions. A variety of studies have identified gendered trait preferences, but do not systematically analyze differences or interactions gender with other dimensions, household characteristics, geographic factors. study integrates 1000minds survey trade-off analysis Rural Household Multi-Indicator Survey cassava Nigeria a major product, gari.

Whole-genome sequencing and comparative genomics reveal candidate genes associated with quality traits in Dioscorea alata

BMC Genomics, Год журнала: 2024, Номер 25(1)

Опубликована: Март 6, 2024

Abstract Background Quality traits are essential determinants of consumer preferences. Dioscorea alata (Greater Yam), is a starchy tuber crop in tropical regions. However, comprehensive understanding the genetic basis underlying yam quality remains elusive. To address this knowledge gap, we employed population genomics and candidate gene association approaches to unravel factors influencing attributes boiled yam. Methods Results Comparative analysis 45 plant species revealed numerous novel genes absent existing D. annotation. This approach, adding 48% more genes, significantly enhanced functional annotation three crucial metabolic pathways associated with traits: pentose glucuronate interconversions, starch sucrose metabolism, flavonoid biosynthesis. In addition, whole-genome sequencing 127 genotypes identified 27 under selection 22 linked texture, content, color through analysis. Notably, five involved content cell wall composition, including 1,3-beta Glucan synthase, β-amylase, Pectin methyl esterase, were common both their expression levels assessed by transcriptomic data. Conclusions The study specific allowed identification important for quality. Our findings provide insights into will help enhancement breeding programs.

Abstract BACKGROUND Nigeria and Cameroon are multi‐ethnic countries with diverse preferences for food characteristics. The present study aimed to inform cassava breeders on consumer‐prioritized eba quality traits. Consumer testing was carried out using the triadic comparison of technologies (tricot). Diverse consumers in villages, towns cities evaluated overall acceptability made from different genotypes. Data both were combined linked laboratory analyses gari used make it. RESULTS There is a strong preference higher cohesiveness brightness especially Cameroon, lower redness yellowness. Relatively hardness springiness values preferred Nigerian locations, whereas Cameroon. Trends solubility swelling power differ between two countries. also reveals that older improved genotype TMS30572 benchmark superior characteristics across regions Nigeria, recently released variety Game changer performs very well In genotypes Obansanjo‐2 TM14F1278P0003 have good stability CONCLUSION wide acceptance single geographical cultural conditions as three acceptable new varieties indicates consumers' surprisingly homogeneous eba. This would enhance breeding efforts develop wider expand potential target areas varieties. © 2023 Authors.

This study investigated the trait preferences for cassava in context of climate change and conflict stressors among value-chain actors Nigeria to strengthen social inclusion community-resilience outcomes from breeding programs. Multi-stage sampling procedures were used select interview male female participants Osun, Benue Abia States. The results indicated that farmers preferred traits such as drought tolerance, early bulking, multiple-product use in-ground storability resilience. Climate challenges related shaped response strategies both genders, influenced preferences, including re-emergence leaves, stems had ratooning potential, especially root milking was important respondents. major employed by men included frequent farm visits prevent theft engaging non-agricultural livelihoods. Those women backyard farming, harvesting, having food with fewer processing steps, depending on remittances. resilience capacity higher than due their better access assets, well abilities relocate farms out-migrate search other Considering gendered traits, enhancing strategies, can complement efforts make more socially inclusive, resilient, anticipatory future created changes.

Roots, tubers and cooking bananas are bulky highly perishable. In Africa, except for yams, their consumption is mainly after transport, peeling in the form of boiled pieces or dough, a few days harvest. To stabilize better preserve products and, case cassava, release toxic cyanogenic glucosides, range intermediate have been developed, related to fermentation drying numerous processing operations. This review highlights, first time, impact genotypes on labour requirements, productivity associated drudgery operations primarily carried out by women processors. Peeling, soaking/grinding/fermentation, dewatering, sieving toasting steps were evaluated wide new hybrids traditional landraces. The highlights studies gari production from cassava. results show that, depending used, women's required can be more than doubled even sum weights transported along process up four times higher same quantity end product.

A gendered assessment of crop traits to improve breeding product design and uptake: the case of potato in Kenya

Frontiers in Sustainable Food Systems, Год журнала: 2024, Номер 8

Опубликована: Июль 11, 2024

The study assesses the gender implications of a target product profile for table potato in Kenya. Breeding programs mostly emphasize farmers’ trait requirements and rarely pay attention to other value chain actors’ preferences. This partially contributes low uptake improved varieties. Therefore, efforts are required assess crop proposals during development, testing, dissemination. In this paper, we traits targeted by breeding program Kenya using G+ tools. applies tool examine instances selected may exacerbate disparity along four domains: unpaid labor, access employment opportunities, requiring extra inputs control over benefits. We use mixed methods including review social scientists, key informant interviews multistakeholder workshop gather insights from female male farmers, breeders, stakeholders. Findings show that pest, disease resistance, shelf-life benefit women men customer segments. On hand, earliness, dry matter, yield could increase drudgery women. demand women’s labor harvesting, sorting food preparation time while also displacing profitable nodes. recommend gender-responsive strategies accompany release variety mitigate inequities enhance adoption.
