Production of A Tempeh-Like Product. Using Indigenous Leguminous Crops

CHARiTY NOIDI IBEH | 61 pages (8794 words) | Projects

ABSTRACT

Local cowpea (sample A) and African Yam bean (Sample B) were used to produce a tempeh-like product using soya bean as a control (Sample C) and Rhizopus as a starter. Proximate and microbial analysis were conducted on the products. They examinations revealed in- crease in protein, moisture and ash contents and also reduction in crude fibre, fat and carbohydrate. Apart from the Rhizopus specie used as a staer culture during fermentation, Lactobacillus species and yeast cells were isolated after the initial soaking and fermentation of the products. Sensory evaluation showed that sample A was similar to sample C in texture and appearance but significantly (p< 0.05) different from sample B. Sample B showed had similar taste with C. The samples were similar

to control (Sample C) in general acceptability.
