Assessment of Grain Safety in Developing Nations
ASSESSMENT OF GRAIN SAFETY IN DEVELOPING NATIONS by José Rodrigo Mendoza Jiménez A DISSERTATION Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of Requirements For the Degree of Doctor of Philosophy Major: Food Science & Technology Under the Supervision of Professors Andréia Bianchini and Jayne E. Stratton Lincoln, Nebraska December, 2020 ASSESSMENT OF GRAIN SAFETY IN DEVELOPING NATIONS José Rodrigo Mendoza Jiménez, Ph.D. University of Nebraska, 2020 Advisor: Andréia Bianchini Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor quality grain. Fungi are contaminants of maize and some can produce toxins, known as mycotoxins, that both devalue crop marketability and have detrimental health effects, especially to those malnourished. As some households depend on their harvest for self- consumption, losses due to fungi endanger their food security. To abate the threat posed by mycotoxigenic fungi on maize among developing nations, this research was conducted as a compilation of works in several countries. More specifically, it describes agricultural practices currently in use in developing nations, provides an overview of mycotoxin prevalence and approaches that can be used to improve grain safety post-harvest through proper storage. -
Maize Processing in Tanzania: Prospects for SME Participation
Maize Processing in Tanzania: Prospects for SME Participation Project Brief, June 2020 ES/S0001352/1 Dr H.B.Lunogelo, Dr Hazel Gray and Professor Fortunata Makene www.iiap.info Project Overview Innovation and Inclusion Industrialisation in Agro-Processing is a two-year collaboration between researchers from the University of Edinburgh, the University of Johannesburg, and the Economic and Social Research Foundation, Tanzania. The project is a comparative study conducted across Tanzania and South Africa focusing on three value chains: maize meal, citrus and dairy. The three aims of the study are: First, to describe the factors that determine innovation and inclusion in agro-processing Second, explain the challenges to promoting SME participation in agro-processing value chains Third, to use these findings to support industrial policy formulation at the national and regional level In this project brief, we set out the key issues arising from our scoping work on maize milling in Tanzania. 1: Summary As an economic crop, maize accounts for 74.3% of cereals production and 66% of all crops harvested annually (NBS, 2017)1. It contributes about 40% of calorific foods consumed (Bymolt et.al., 20172). Maize flour is used to make a meal popularly known as ‘ugali’. SMEs play a major role in the midstream of the maize value chain. Micro and small-scale maize millers are particularly prominent in rural settings and small trading centres but they also operate in larger towns and cities. The maize milling business has also attracted medium and large- scale investors with national and regional market outreach for their milled and packaged products. -
Physico-Chemical and Sensory Properties of “Agidi” from Pearl-Millet (Pennisetum Glaucum) and Bambara Groundnut (Vigna Subterranean) Flour Blends
African Journal of Food Science Vol. 4(10), pp. 662-667, October 2010 Available online http://www.academicjournals.org/ajfs ISSN 1996-0794 ©2010 Academic Journals Full Length Research Paper Physico-chemical and sensory properties of “Agidi” from pearl-millet (Pennisetum glaucum) and bambara groundnut (Vigna subterranean) flour blends U. M. Zakari, A. Hassan and E. S. Abbo* Department of Food Technology, Kaduna Polytechnic, Kaduna, Nigeria. Accepted 8 September, 2010 Agidi was produced from different formulations of pearl millet ogi and Bambara groundnut flours. Six agidi products were produced at the laboratory scale with one as the control. The recipe formulations for the products were 100:0, 95:5, 90:10, 85:15, 80:20 and 75:25 pearl millet to bambara groundnut flours, respectively. The six formulated products were subjected to proximate, physico chemical and sensory analysis. The results showed that the protein contents increased with increased addition of bambara groundnut flour. The protein contents ranged from 2.44 to 7.0% on dry weight basis. The fat contents ranged from 1.25 to 3.1%. Carbohydrate content ranged from 71.2 to 77.7%. The physico- chemical parameters also varied. The pH ranged from 4.13 to 4.40 while titratable acidity ranged from 0.02 to 0.03. The bulk density increased from 0.32 to 0.44 g/ml as the proportion of bambara flour increased. The sensory panelists rated the products highly for all the parameters investigated. Product B with the proportion of 90:5 pearl millet to bambara flour was most acceptable to the panelists. -
Hopi Crop Diversity and Change
J. Ethtlobiol. 13(2);203-231 Winter 1993 HOPI CROP DIVERSITY AND CHANGE DANIELA SOLER I and DAVID A. CLEVELAND Center for People, Food, and Environment 344 South Third Ave. Thcson, AZ 85701 ABSTRACT.-There is increasing interest in conserving indigenous crop genetic diversity ex situ as a vital resource for industrial agriculture. However, crop diver sity is also important for conserving indigenously based, small-scale agriculture and the farm communities which practice it. Conservation of these resources may best be accomplished, therefore, by ensuring their survival in situ as part of local farming communities like the Hopi. The Hopi are foremost among Native Ameri can farmers in the United States in retaining their indigenous agriculture and folk crop varieties (FVs), yet little is known about the dynamics of change and persis tence in their crop repertoires. The purpose of our research was to investigate agricultural crop diversity in the form of individual Hopi farmers' crop reper toires, to establish the relative importance of Hopi FVs and non·Hopi crop vari eties in those repertoires, and to explore the reasons for change or persistence in these repertoires. We report data from a 1989 survey of a small (n "" 50), oppor tunistic sample of Hopi farmers and discuss the dynamics of change based on cross·sectional comparisons of the data on crop variety distribution, on farmers' answers to questions about change in their crop repertoires, and on the limited comparisons possible with a 1935 survey of Hopi seed sources. Because ours is a small, nonprobabilistic sample it is not possible to make valid extrapolations to Hopi farmers in general. -

P.2* 1Department of Food Technology, Lagos State Polytechnic , Ikorodu Lagos, Lagos State, Nigeria. 2Department of Agricultural Engineering, Federal University of Technology, Akure, Ondo State, Nigeria. Received 13 August, 2014; Accepted 16 September, 2015 Socio-economic relevance of fermented food in developing countries is evident. However, the production of this category of food is still achieved under primitive conditions. Ogi a fermented product from maize, sorghum or millet is usually transformed into gruel or porridge when heated. About a quarter of Nigeria population is said to consume Ogi on a weekly bases. This coupled with increasing industrialization and urbanisation in the country may however dictate the need for large-scale production of Ogi. The proposal for industrialisation of this process will lead to a deliberate and calculated combination of chemical or mechanical steps to aid the manufacture of this product. However, the growth of small-scale or large industries for this product may be confronted with some limiting factors prevalent in most third world countries. Ogi production have some similarities in unit operations when compared with corn starch production, therefore the same technologies may be adopted with appropriate modification in the production of Ogi and this will provide employment to a number of people. -

Abuah 1Department of Mechanical Engineering, Faculty of Engineering, 2Department of Animal Science, Faculty of Agriculture, 3Department of Agricultural Engineering,Faculty of Engineering, Ahmadu Bello University, Zaria Abstract: The storage characteristics of uncooked Ogi-baba (Sorghum based cereal breakfast) after drying for some time at an elevated temperature of 130ºC was the main objective of this experimental work. The experiment also aimed at checking the influence of accelerated drying on the quality and storage life span of the product. The performance was accessed using some organoleptic (odour, colour and fungi invasion count) characteristics at a weekly interval for four weeks by 10 human subjects – confirmed medically fit in their use of olfactory and visual organs. The experimental samples were opened to the atmosphere while the control is sealed immediately the dried product was cooled to room temperature. The 60 min heating was found to have the most stable colour and odour and this property is even more stablized when the product is sealed (as in the control sample). On the other hand, the 60min sample is most loaded with fungi as the experiment progresses but no fungi intestation when sealed, the 20 and 40 min samples (even when sealed) had fungi investation.
