Abstract

Legume flour enrichment can enhance the nutritional value of many cereal products, in line with the current dietary recommendations of the World Health Organization. The aim of this study based on a survey of 105 consumers was firstly to investigate the perception and acceptance of Tunisian consumers with regard to including legumes in their diet, but also to be innovative in their consumption habits. Secondly, among the legumes listed in the survey, chickpeas and lentils were selected by the respondents and were added in different proportions to supplement bread and cake formulations. Moisture content, protein and ash of common wheat and legume flours and of the legume-enriched products were determined and compared to those of the control products. Crust and crumb color measurements were run on in final products. Sensory evaluations were also performed through a hedonic test and a linear scale test. The results showed that legume flour enrichment of bread and cake was a viable alternative and that consumers were aware of the fact that legumes are a source of dietary minerals and proteins. The challenge of including high percentages of legumes (between 20% and 40%) was met in this study with no major technological and organoleptic impairment.
