SCOPE OF THE JOURNAL The African Journal of Food and Nutritional Security publishes a wide range of contributions-review articles, original research, technology innovations, market updates, book reviews, calendar of events and letters to the editor-concerning the entire food chain, from production, processing, to the market and household, in respect of the policy environment, R&D, agro-business, agro-industry, health industry, and consumer. All contributions are assessed by international authorities prior to approval for publication. Nonetheless, the final decision rests with the Editor-in-Chief. Copyright for material accepted for publication will transfer to the publisher. AUTHORSHIP The responsibilities of the authors when submitting a contribution to The African Journal of Food and Nutritional Security are to ensure that the work is original, that it has not been submitted to another journal or publisher and that it has been approved for submission to this Journal by all its authors and the host institution(s) of the authors. It is, further, the responsibility of the authors to obtain copyright permission to reproduce tables or figures first published elsewhere and to ensure the accuracy of all references. Where there are several authors for a manuscript, the leading author, to whom all correspondence will be sent, should be clearly identified. MANUSCRIPT PREPARATION Manuscripts should be typewritten or computer processed on A4 size plain white paper, double-spaced throughout, with wide margins all round and free of errors. Complex mathematical equations must be hand-written for clarity when typesetting. The format of the research articles should take the following order: title page, Abstract, Key Words, Introduction, Materials and Methods, Results and Discussion, Conclusions, Acknowledgements, and References. The Journal accepts two copies of the manuscript, together with a diskette clearly marked in pencil the title of the contribution, the author(s) and stating the word processor programme and system used. Illustrations should be black-and-white. If colour is necessary, the cost of colour separation and production shall be charged to the author. Figures, which must be cited in the text, must be numbered on the reverse in pencil with the author's name, a shortened title, and the top indicated. Lettering on the figures must be sharp and dark enough to withstand reduction. Legends to figures should be typed on a separate page.
