Production, consumption, and quality attributes of Akpan - a yoghurt-like cereal product from West Africa
01.11.2012
Akpan is a high-potential, traditional yoghurt-like product made from fermented cereal starch, and consumed as a thirst-quenching beverage in Benin. This study investigated the characteristics of consumers, the traditional processing techniques and constraints, and the quality attributes of the product in order to find out the best options for possible industrial development. For this purpose, a survey was carried out in different municipalities using a questionnaire administered to stakeholders. While the production and commercialization of Akpan are undertaken exclusively by women, consumption cuts across all classes of people, with consumers in a wide range of socio-cultural groups, ages, and educational levels. Four types of Akpan were encountered, varying in their raw materials and processing technologies. Maize and sorghum were used either singly or in combination through submerged or solid-state fermentation processes. Among the product types, Akpan from maize ogi was the most preferred, mainly because of its long-established history, white colour, sour taste, and pronounced ogi aroma. -
Processing and quality attributes of gowe: a malted and fermented cereal-based beverage from Benin
01.06.2014
Gowe is a sweetish paste of malted, fermented, and cooked sorghum and/or maize flour, consumed in its pure state, but preferentially as a beverage after homogenizing with water, sugar, milk, and ice. A survey was carried out at different localities in the traditional gowe producing areas to investigate the diversity of the processing techniques, consumers’ characteristics, and the quality attributes. Producers and sellers were women exclusively while consumers cut across all classes of age, socio-cultural groups, and educational levels. Gowe varied in cereal and processing techniques, with maize and sorghum being used either singly or in combination (maize/sorghum ratio varying from 1 to 3) through four processes. Apart from the alternative process which leaves out the malting step, gowe processing techniques aim at producing sweetish and acidic tasting products through malting, saccharification, and fermentation. A principal component analysis plot of quality criteria of gowe indicated that the preference of consumers was directly associated with the perceptions of producers. -
Kenkey production, vending, and consumption practices in Ghana
01.10.2014
A survey was conducted to study production, vending, and consumption of kenkey, a sour dumpling in Ghana. Information was obtained on the socio-cultural profile of the actors, processing technologies, practices which adversely affected product quality, shelf life, and quality attributes important to consumers. Kenkey production and retailing was the domain of women, and carried out mainly as a family business in home-based operations. Three types of kenkey were encountered: Ga-, Fanti-, and nsiho-kenkey. Production was dominated by the Ga and Fanti socio-cultural groups but consumption cut across all socio-cultural groups. The majority of producers processed 10–100 kg of maize per week but frequency of production varied from 1 to 10 times in a week. Unit operations in kenkey production were labour intensive and manually carried out apart from milling. The texture of kenkey was more critical to most consumers than taste and depended on a procedure called aflatalization yielding a product with a semi-sticky, elastic consistency.
