Development and characterization of biodegradable films from fermented yam (Dioscorea trifida L. f.) [PDF]

African Journal of Food Science, 2019
The objective of this work was to develop and characterize biodegradable starch films at 14 and 21 days of fermentation, aiming to develop packaging with added value. For the extraction of starch, yam tubers were washed, crushed, filtered and fermented for 14 and 21 days, and then filtered and dehydrated. Water-starch-glycerol mixtures were prepared in

Review of empirical and emerging breeding methods and tools for yam (Dioscorea spp.) improvement: Status and prospects

Plant Breeding, Volume 139, Issue 3, Page 474-497, June 2020., 2020
Abstract Yam (Dioscorea spp.) is an important tuber crop with tremendous potential as a functional food in the tropics and subtropics. However, the crop has not shown progressive productivity gain over decades due to various production constraints. This paper reviews the progress achieved in empirical breeding endeavours and the development, status and

Starchy shells: Residue analysis of precolonial northern Caribbean culinary practices

Archaeometry, Volume 62, Issue 2, Page 362-380, April 2020., 2020
Determining culinary practices is critical for understanding phytocultural complexes, transported landscapes and human niche constructions. Starch analysis is an exemplary method for reconstructing human–plant dependencies. However, certain types of artefacts from the Greater Caribbean region, such as flaked lithics, lithic griddles, coral artefacts ...

Characterization and genetic diversity of Dioscorea bacilliform viruses present in a Pacific yam germplasm collection

Plant Pathology, Volume 69, Issue 3, Page 576-584, April 2020., 2020
The Pacific yam germplasm collection was screened for badnavirus infection using RCA and sequencing, with 35 out of 224 accessions testing positive and two virus species identified, namely DBALV and DBALV2. Abstract Yam is an important food staple in many Pacific Island countries, but its production is limited by several factors including virus ...

Evidence of diploidy in the wild Amerindian yam, a putative progenitor of the endangered speciesDioscorea trifida(Dioscoreaceae)

Genome, 2010
The fundamental question about Dioscorea trifida (Dioscoreaceae), the most important Amerindian yam, that remains unresolved concerns its evolutionary origin, since no wild relative has been reported. In this paper we report the existence of D. trifida’s wild relative for the first time. The diploidy of wild D. trifida (2n = 40) is clearly demonstrated

Physicochemical, Functional, and Macromolecular Properties of Waxy Yam Starches Discovered from “Mapuey” (Dioscorea trifida) Genotypes in the Venezuelan Amazon [PDF]

Journal of Agricultural and Food Chemistry, 2010
"Mapuey" tubers in Venezuela are staple food for indigenous peoples from the Caribbean coast and Amazon regions. Noticeable differences between genotypes of yam starches were observed. Granules were large, triangular, or shell-shaped with monomodal particle size distribution between 24.5 and 35.5 μm.

Amino Acid Profiles, Total Nitrogen Contents, and Computed‐Protein Efficiency Ratios of Manihot esculenta Root and Dioscorea rotundata Tuber Peels

Journal of Food Processing, Volume 2016, Issue 1, 2016., 2016
Tuberous roots of cassava and yam are major sources of dietary carbohydrate to human, alternative sources of energy in livestock feeds, and sources of starch in small‐scale industries. Investigations on amino acid profiles, total nitrogen contents, and computed‐protein efficiency ratios (C‐PER) of tuberous root peels of Manihot esculenta Crantz and ...

Barrier, Mechanical and Antimicrobial Properties of Yam Starch Film With Cássia Cinnamon Essential Oil and Its Application in Strawberry Storage

Packaging Technology and Science, Volume 38, Issue 8, Page 681-697, August 2025.
Chitosan and cinnamon oil reduced film thickness and improved water vapor barrier properties. Cinnamon oil in yam starch films showed strong antibacterial activity against E. coli and S. aureus. Yam starch films with chitosan and cinnamon oil effectively inhibited fungal growth on strawberries.

Development of Genomic Simple Sequence Repeat Markers for Yam

Crop Science, Volume 55, Issue 5, Page 2191-2200, September-October 2015., 2015
ABSTRACT Yam (Dioscorea spp.) is a major staple crop widely cultivated for its starchy tubers. To date, very few marker resources are publicly available as tools for genetic and genomic studies of this economically important crop. In this study, 90 simple sequence repeat (SSR) markers were developed from an enriched genomic library of yellow Guinea yam
