Title: Sensory profile and acceptability of Kenkey and other fermented maize products in Ghana
The sensory profile and consumer acceptance of different types of Kenkey and other fermented maize products in Ghana were investigated. In the quantitative descriptive analysis, a PCA bi-plot grouped the products based on colour, odour, taste and texture into five classes; (i) Ga Kenkey, (ii) Fanti Kenkey, (iii) Normal Banku, FRI Banku, Neat Banku, (iv) Sweet Kenkey, White Kenkey–Atim, White Kenkey–Senchi, and (v) Kafa. The acceptability of the grouped products was tested by two consumer groups: 110 Ghanaians and 90 Caucasians in Accra and Tema. Sweet Kenkey and White Kenkey were the most preferred by the Caucasians, whilst Sweet Kenkey and Ga Kenkey were the most preferred by the Ghanaians. Socio-economic factors such as level of education, ethnicity, nationality, age, gender, occupation, residential status in Ghana and marital status of the consumers did not significantly influence (p>0.05) the acceptability of all samples tested. Three classes of behaviours of consumers were identified. Those who liked all the products ‘all likers’ (36%), those who preferred the white Kenkeys ‘white likers’ (30%) and those who preferred Banku ‘banku likers’ (34%). 48% of the Caucasian consumers were white likers, 43% banku likers and 9% all likers, whilst 54% of the Ghanaians were all likers, 31% banku likers, and 15% white likers. Sensory attributes important for the white likers were whitish colour, fruity odour, smooth and non-sticky texture, a less sour product without a pronounced fermented odour, and a bland taste. All likers and banku likers were not very discerning consumers; whilst only salty taste correlated significantly with acceptance for the banku likers, none of the sensory attributes correlated with acceptance for the all likers. Based on these considerations two products will be re-engineered one targeting the white likers and another targeting the banku and the all likers.
