'Yellow is good for you': Consumer perception and acceptability of fortified and biofortified cassava products.

Vitamin A, an essential micronutrient for health, can be obtained from various food sources including cassava products made from either traditional white cassava varieties fortified with red palm oil containing provitamin A, or new high provitamin A biofortified yellow cassava varieties. Both products have a similar yellow appearance due to the coloured pigmentation of provitamin A. Using a range of methods to provide a comprehensive understanding of sensory acceptability (blind triangle test, sensory profiling, hedonic preference that included Check-all-that-applies and Just-about-right tests), we tested the acceptability and nutritional perception of traditional West-African food dough-like products (eba and fufu) made from biofortified, fortified, or control products made with non-fortified white cassava (n = 7) at three suburban locations near Ibadan, Nigeria on a total of 122 consumers.

Physical losses could partially explain modest carotenoid retention in dried food products from biofortified cassava.

Gari, a fermented and dried semolina made from cassava, is one of the most common foods in West Africa. Recently introduced biofortified yellow cassava containing provitamin A carotenoids could help tackle vitamin A deficiency prevalent in those areas. However there are concerns because of the low retention of carotenoids during gari processing compared to other processes (e.

Sensory optimization of crackers developed from high-quality cassava flour, starch, and prawn powder.

Crackers produced from high-quality cassava flour (HQCF), cassava starch, and prawn powder were optimized based on sensory preference testing. Ten different formulations of crackers were produced using mixture design. These were subjected to sensory evaluation using attributes such as taste, crispiness, puffiness, and acceptability on a 7-point hedonic scale.

Cross-cultural acceptance of a traditional yoghurt-like product made from fermented cereal.

Background: Akpan is a traditional ready-to-drink fermented yoghurt-like cereal beverage consumed in urban and rural areas in Benin. With the aim of adapting the product to new local and export markets, this work maps African and European consumer preferences for different types of Akpan.

Results: A sensory profile of Akpan was created and consumer tests were conducted with 103 consumers of African origin and 74 consumers of European origin.

Relationships between anthocyanins and other compounds and sensory acceptability of Hibiscus drinks.

Chemical composition of Hibiscus drinks (Koor and Vimto varieties, commercial and traditional, infusions and syrups) (n=8) was related to sensory evaluation and acceptance. Significant correlations between chemical composition and sensory perception of drinks were found (i.e.

Retention and bioaccessibility of β-carotene in blended foods containing orange-fleshed sweet potato flour.

The retention and bioaccessibility of β-carotene (BC) in blended foods made with part orange-fleshed sweet potato (OFSP) flour (30%) were examined. Chapatis and porridges were prepared by local processors under field conditions (FC) in Uganda (n=10). While the retention of all-trans-BC in porridges (69 to 93%) and chapatis (70 to 97%) varied between the processors, there was no overall difference between the two products and this was probably because of the variability in FC.
