Four oilseeds providing cocoa-butter substitutes--shea, pentadecima, illipe, and salseed--when tested as substrates for aflatoxin production by two strains of Aspergillus parasiticus, gave varying levels of aflatoxin. Aflatoxins were found at low levels occurring naturally in moldy shea-nuts, but none of 21 commercial shea-nut samples contained greater than 20 micrograms of aflatoxin B1 per kg.

phosphoric acid (h3po4) and zinc chloride (zncl2) catalyzed shea nut shells, subjected to a one way activation scheme was employed to study the adsorption kinetics and mode of diffusion of industrial dye uptake. thermodynamics data obtained in this study indicate that the sorption of dye spontaneously increases with time and decreases after equilibration was reached. the adsorption follows the ...

Czech J. Food Sci., 32: 578–584. Cooking and drying conditions of the shea butter extraction process were determined using a response surface methodology. The influence of cooking time, temperature, a...

The study compared the shea-butter production techniques used among women processors in Baruten and Ilorin-South Local Government Areas of Kwara State, Nigeria. A multistage sampling technique was used to elicit information from 120 respondents through a structured interview schedule with questionnaire. Data were analyzed with both descriptive and inferential statistics. The mean age of the res...

Four triterpene acetates, alpha-amyrin acetate (1a), beta-amyrin acetate (2a), lupeol acetate (3a), and butyrospermol acetate (4a), and four triterpene cinnamates, alpha-amyrin cinnamate (1c), beta-amyrin cinnamate (2c), lupeol cinnamate (3c), and butyrospermol cinnamate (4c), were isolated from the kernel fat (n-hexane extract) of the shea tree (Vitellaria paradoxa; Sapotaceae). Upon evaluatio...

The importance of shea tree to the people of south-western Nigeria cannot be over emphasized considering both the economic and environmental uses of the tree. However, efforts have not been made to propagate its production by the farmers as the shea tree still grows in the wild state. It would be worthwhile to investigate farmers’ perception of shea nut tree as an economic tree and their attitu...

Two traditional treatments for shea (Vitellaria paradoxa) butter processing namely storage of fresh nuts and duration subsequent boiling were studied by using the response surface methodology (RSM) to determine best treatment. Experimental influenced several kernel parameters, such as fat content (38-52% dw), redness (a* values between 6.3 11.7), viz. yield (24 36% wet weight mass), brightness ...
