Nutritional and microbiological quality of common beans (Phaseolus vulgaris L.) cooked with or without the use of soaking water

Abstract

The aim of this work was to evaluate the nutritional and microbiological quality of common beans (Phaseolus vulgaris L.) processed with or without soaking water. Two common bean cultivars grains (Iraí and BRS Expedito) were subjected to soaking in distilled water for eight hours, at environmental temperature. The cooking was made with the use or discard of soaking water. The minerals were determinated in grains and broth separatedely and microorganisms associated. The results did not show changes for the minerals content in grains and broth with discard of the soaking water. The bean broth showed high phosphorus, potassium, magnesium and sulfur content. The discard of the soaking water did not improve microbiological quality of the processed common beans. Iraí and BRS Expedito cultivars may be cooked with the use or discard of soaking water because minerals content and microbiological quality of the processed common beans are maintained.
