“IMPROVING TRADITIONALLY FERMENTED AFRICAN FOODS THROUGH BIOTECHNOLOGY”- Need to translate art to science

Article in Press

Africa has a lot of fermented foods which need to be further developed for improved nutrition. Many authors have documented interesting articles and reviews on fermented foods from different parts of the world. The climate in many African countries favours short-term storage of fresh foods. Storage facilities are inappropriate and the supply of light energy is irregular. This suggests that fermentation might serve as an...
