Mineral profile and characterisation of cookies made from legume green grain flour

Abstract

The aim of this work was to determine and compare the mineral composition and physico-chemical parameters of formulations of cookies developed by hand based on Lablab purpureus (L.) Sweet (mangalo—BFM), Vigna unguiculata (L.) Walp. (cowpea beans—BFC) and Cajanus cajan (L.) Huth (pigeon pea—BFP) flours. The results indicate that the cookies have a high content of essential minerals (mainly K, P and Ca). Moisture (4.48-8.44%) was below the maximum value established by Brazilian legislation, and lipids (6.35-6.56%) and ash (3.33-3.96%) were like products found in the market and literature. High levels of protein (8.37-9.28%), fibre (3.88-6.39%) and carbohydrates (66.28-71.19%) give the product high nutritional potential. No oxidation products were detected. Water activity and acidity remained satisfactory for good food preservation for 45 days. Sensory evaluation indicates a satisfactory acceptability for the BFM and BFC (overall quality above 7). The desirability data indicated that the BFC obtained the best performance for the chosen parameters. Therefore, the elaborated cookies have high nutritional quality and the pulse flour has potential for the enrichment of food products.
