Nymphaea petersiana Klotzsch (Nyika) is an important wild tuber eaten in some districts of Malawi. The tubers were processed by boiling/freeze-drying(BFD) and sun-drying(USD). The tuber's nutrient and antinutrient composition was determined to produce a preliminary nutrient data base for use in sub-Saharan Africa. There was no significant difference (P > 0.05) in protein content of BFDand USD samples. Sun-dried samples were significantly (P < .05) higher in ash than boiled samples while boiled samples were significantly higher (P < .05) in crude fat and total carbohydrate. The protein content of the tubers (8.0 and 8.1 %) was higher than that of the staple maize (7.9%), African millets (unspecified) (7.5%), and polished rice (7.0%), but lower than sorghum (10.7%). Protein content was higher than tubers like cassava (1.3%), potato (2%), sweet potato (1.6%), yams (1.5%) and N. lotus (5.2). Nyika tubers have a well balanced amino acid content, limiting only in lysine. There were no significant (P > 0.05) differences in the mineral content of BFD and USD samples, except for iron, which was lower in the boiled samples. Nyika tubers have a higher calcium (1376 and 946 ug/g) and phosphorus (2250 and 2883 ug/g ) content than wild and domesticated cassava, potatoes, sweet potatoes and wild and domesticated yams. Sun-dried tubers have a higher iron content (88ug/g) than maize (20ug/g). The zinc content of tuber was higher (21and 25ug/g) than that of boiled maize flour, boiled sorghum flour, rice, cassava, and sweet potato. The predominant fatty acids in the tubers were oleic (47%), linoleic (32%), palmitic (21%) and linolenic (7%) acids. Ascorbic acid content was very low, only 0.1 and 0.003 mg/100g. Tannin content was lower (1 and 1.7 %) in the tubers than in Vulgare Pers. sorghum, DeKalb sorghum from U.S. and Kabale sorghum from Uganda. There was a significantly (P < 0.05) lower content of phytate in boiled (3.9ug/g) than in sun-dried tubers (6.0 ug/g). Phytate content of the tubers was lower than that of cooked maize flour, unrefined maize flour, cassava and sweet potato. Trypsin inhibitor activity in the tubers was reduced from 463 to 55 TIU/g tuber and chymotrypsin inhibitor activity was reduced to 50 from 267 CIU/g tuber by cooking. Nyika is a good source of iron and quality protein limiting only in lysine. Protein is comparable to staple maize and higher than root crops consumed in Malawi. It is not a good source of fat and ascorbic acid. Tannin, phytate, trypsin, and chymotrypsin inhibitor content lower than most food crops consumed in Malawi. / Ph. D.

This thesis explores the origin of one of the most engrossing concerns of the post-colonial Indian state, that is, its extensive, intricate, and expensive feeding arrangements for the civilians. It tracks the colonial origin of the post-colonial welfare state, of which state-management of food is one of the most publicized manifestations. This thesis examines the intervention of the late colonial British state in food procurement and distribution in India during the Second World War, and various forms of such intervention, such as the introduction of food rationing and food austerity laws. It argues that the war necessitated actions on the part of the colonial state to secure food supplies to a vastly expanded British Indian Army, to the foreign Allied troops stationed in India, and to the workers employed in war-industries. The thesis brings forth the constitutional and political predicaments that deprived the colonial central government's food administration of success. It further reveals how the bitter bargaining about food imports into India between the Government of India and the War Cabinet in Britain hampered the state efforts to tackle the food crisis. By discussing the religious and cultural codes vis-à-vis food consumption that influenced government food policies, this thesis has situated food in the historiography of consumption in colonial India. In addition to adopting a political approach to study food, it has also applied sociological treatment, particularly while dealing with how the wartime scarcity, and consequent austerity laws, forced people to accept novel consumption cultures. It also contributes to the historiography of 'everyday state'. Through its wartime intervention in everyday food affairs, the colonial state that had been distant and abstract in the perception of most common households, suddenly became a reality to be dealt with in everyday life within the domestic site. Thus, the macro state penetrated micro levels of existence. The colonial state now even developed elaborate food surveillance to gather intelligence about violation of food laws. This thesis unravels the responses of some of the political and religious organizations to state intervention in quotidian food consumption. Following in this vein, through a study of the political use of famine-relief in wartime Bengal, it introduces a new site to the study of communal politics in India, namely, propagation of Hindu communal politics through distribution of food by the Hindu Mahasabha party. Further, it demonstrates how the Muslim League government's failure to prevent the Great Bengal Famine of 1943-44 was politically used by the Mahasabha to oppose the League's emerging demand for the creation of Pakistan.
