Item Overview of dairy processing and marketing in East African dairy value chains: Opportunities and challenges(African Journal of Food Science, 2016) Lokuruka, Michael N.IWorldwide, the dairy sector is one of the fastest growing productive sectors. The global sector growth in the decade 2011 to 2020 is projected to be higher than that experienced in 2000 to 2010, mainly due to expected robust growth in developing countries. Global milk production in 2014 stood at about 800 million metric tons. India is the global leader in milk production accounting for 16% of output, with the USA coming second with 14.6% of global production, while Africa produces less than 10% of global output. Sub-Saharan Africa commands 0.2% of the global trade volume in the dairy sector. Egypt is the African Continental leader in milk output, as Africa remains the largest importer of milk powders, butter and ghee. The shortfalls in demand show potential investment opportunities and growth areas in the sector. The East African output of butter and ghee stands at about 15% of the African output of these products. Kenya and Uganda produce considerable amounts of processed dairy products, although, the milk processed rarely exceeds 12 to 15% of domestic milk supply, with most milk production being consumed at farm level. Tanzania produces more butter and ghee than other East African Community (EAC) members with Burundi been the least. Although, informal marketing channels, offering cheaper fresh milk are attractive, increasing decentralization of regulatory services, growing effectiveness of law enforcement and consumer awareness of the healthfulness of processed milk, will continue to reduce informal marketing of unprocessed fresh milk in EAC countries. Despite the quest for global export, the unmet domestic dairy products demand in EAC member states may slow entry into global markets. To meet the numerous requirements in export markets requires cautious, planned and systematic forays over time.Item Effect of Some Processing Methods on Nutrient Content and Anti-Nutritional Factors of a Variety of Dolichos Lablab (Lablab Purpureus L.) Beans Grown in Kenya(Journal of Food and Nutritional Sciences Research, 2019) Kilonzi, Sheila M.; Makokha, Anselimo O.; Kenji, Glaston M.This study aimed to determine the effect of different processing methods on the proximate composition and anti-nutritional factors of Dolichos lablab beans (Lablab purpureus) of Kenya. The seeds of KAT/DL-2 variety,sourced from Kenya Agricultural Livestock and Research Organisation, Katumani Dryland Research Station were sorted, then subjected to different processing methods (soaking, cooking and germination). The samples were analysed for proximate composition, tannins, phytates and trypsin inhibitory activity. The results showed a significant increase (2.0%) in crude protein content for germinated lablab beans while carbohydrates content was high in cooked samples. The variety KAT/DL-2 had high levels of phytates; 723.6 mg/100g and tannins 330.3mg/100g and trypsin inhibitor activity 1.3mg/100g. Cooking achieved the highest reduction of anti-nutrients with 88% reduction in TIU. The results revealed that the anti-nutrients in lablab beans can be reduced using different methods of processing. However, there is need to investigate the effect of combined methods on the nutrients and anti-nutrients.
