Profiling The Cell Wall Polysaccharides Of Hemp (Cannabis Sativa L.) Inflorescence And Hempseed And Exploring Their Application As Ruminant Feed Ingredients, Miranda Agbana Jan 2023

Profiling The Cell Wall Polysaccharides Of Hemp (Cannabis Sativa L.) Inflorescence And Hempseed And Exploring Their Application As Ruminant Feed Ingredients, Miranda Agbana

Theses and Dissertations--Animal and Food Sciences

Hemp (Cannabis sativa L.) is used in the United States as a source of CBD oil, fiber, and grain. While hempseeds are consumed whole or as dehulled hemp hearts, hempseed oil is also a desirable seed oil in human nutrition. The process of collecting hempseed oil leaves behind hempseed cakes that are abundant in protein and fiber. Feeding of hempseed cakes to animals, including ruminants, has only initially been explored. Extraction of CBD from hemp inflorescences generates organic waste that may find a second purpose as a fiber feed for cattle. Little is known about the exact fiber composition …


Phylogenetic Diversity Of Arkansas Vineyard And Wine Microbiota, Natacha Cureau May 2020

Phylogenetic Diversity Of Arkansas Vineyard And Wine Microbiota, Natacha Cureau

Graduate Theses and Dissertations

Microorganisms inhabiting the soil, leaves, and grapes in vineyards influence the terroir, a set of environmental factors that impact wine characteristics. Previously, the main method to identify microorganisms was to culture on different media, but a large portion (> 99%) could not be cultured and were consequently unidentified. However, the emergence of new molecular tools has enabled further study and identification of microorganisms such as indigenous vineyard microbiota. The objective of this research was to investigate the phylogenetic diversity of Arkansas vineyard and wine microbiota using high-throughput sequencing. In terms of the Arkansas vineyards, the fungal and bacterial diversity of …


Genau, Charles (Fa1212), Manuscripts & Folklife Archives Oct 2018

Genau, Charles (Fa1212), Manuscripts & Folklife Archives

FA Finding Aids

Finding aid only for Folklife Archives Project 1212. Student paper titled “Winemaking: The Old and New Way” in which Charles Genau details the process of wine production from harvest, to fermentation, bottling, and distribution. Genau compares and contrasts methods of traditional winemaking with contemporary approaches. He also gathered his information from two winemakers of different ages and ethnic backgrounds. The paper contains two illustrations of the winemaking process.


The Use Of Grape By-Products As A Nutrient Rich Cattle Feed, Zachary Christman Mar 2018

The Use Of Grape By-Products As A Nutrient Rich Cattle Feed, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

In this article you will learn about how to use the grape stems, skins and pulp that are generated by the wine industry. Ruminant animals such as cattle can digest this inexpensive yet nutrient rich material. The complete process from wine press to cattle feed is covered in this article. The historical background of using grape by-products and methods to preserve this food source is also presented.

Effect Of Spontaneous Fermentation And Amylase Rich Flour (Arf) On The Nutritive Value, Functional And Viscoelastic Properties Of Cowpea-Fortified Nixtamalized Maize, Dr. Emmanuel Ohene Afoakwa (Phd), Philip Roger Aidoo, Randy Adjonu Apr 2010

Effect Of Spontaneous Fermentation And Amylase Rich Flour (Arf) On The Nutritive Value, Functional And Viscoelastic Properties Of Cowpea-Fortified Nixtamalized Maize, Dr. Emmanuel Ohene Afoakwa (Phd), Philip Roger Aidoo, Randy Adjonu

Professor Emmanuel Ohene Afoakwa

Studied were conducted to evaluate the combined effects of spontaneous fermentation and Amylase Rich Flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2x3x3 factorial design, with fermentation medium, fermentation time and ARF level was performed. The blends were fermented for the specific times and analysed for their titratable acidity, pH, water absorption capacity, viscoelastic properties, texture, protein and mineral content. Fermentation and ARF addition influenced titratable acidity, pH, water absorption, viscoelastic properties and texture of the cowpea-fortified nixtamalized maize. Addition of ARF decreased the viscoelastic properties, texture and pH of all the blends …


Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (Phd), Randy Adjonu, Justice Asomaning Dec 2009

Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (Phd), Randy Adjonu, Justice Asomaning

Professor Emmanuel Ohene Afoakwa

Investigations were conducted on the viscoelastic properties and pasting characteristics of fermented maize with malted cereals and their suitability for infant feeding. A 3x3x2 factorial experimental design with malting time, cereal malt concentration and cereal type was used. Maize, millet, and sorghum malts were added to fermented maize to reducing its bulk density. Samples were analysed for their viscoelastic properties and pasting characteristics using Brabender Viscoamylograph. Sorghum malt in comparison to millet and maize malts was not effective in terms of lowering the hot and cold paste viscosities of the fermented maize. Maize and millet malts liquefied the dough considerably …


Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (Phd), Edem John Kongor, George Annor, Randy Adjonu Dec 2009

Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (Phd), Edem John Kongor, George Annor, Randy Adjonu

Professor Emmanuel Ohene Afoakwa

Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using Brabender Viscoamylograph. Fermentation caused significant variations in the pH, non-volatile acidity and starch concentration. The pH decreased with concomitant increases in non-volatile acidity during co-fermentation of the cassava dough. Soy-fortification upto 20% caused only minimal effects on the pH, titratable acidity and starch content during the fermentation period. Starch content decreased from 69.8%-60.4% within the 48 h fermentation time …


Effects Of Cowpea Fortification, Dehydration Method And Storage Time On Some Quality Characteristics Of Maize-Based Traditional Weaning Foods., Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh, Esther Sakyi-Dawson Jun 2004

Effects Of Cowpea Fortification, Dehydration Method And Storage Time On Some Quality Characteristics Of Maize-Based Traditional Weaning Foods., Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh, Esther Sakyi-Dawson

Professor Emmanuel Ohene Afoakwa

Fortification of cereal-based traditional foods with legume protein can improve their nutritional value. It is, however, important to find out the extent to which the addition of cowpea affects the desirable quality characteristics of traditional weaning foods prepared from fermented maize and also to assess the effect of dehydration method and storage time on the chemical, physico-chemical and functional properties of the products. A 3 x 2 x 4 factorial experiment with cowpea level, drying method and storage time as the respective variables was done. The traditional weaning food was prepared by steeping maize in water for 24 hours, mixed …
