Effect of ingredients on cooking quality, textural properties, and microstructure of fresh mung bean by‐product gluten‐free pasta

Abstract

SummaryMung bean by‐product (MBB), containing high protein and dietary fibre, was selected as the main ingredient to make fresh gluten‐free pasta. Effects of MBB flour, egg white powder (EWP) and water on pasta quality were investigated by extreme vertices mixture design. Seven formulations of MBB pasta were evaluated for colour, protein content, dietary fibre, cooking quality and textural properties. All MBB pasta formulations had significantly higher protein content and dietary fibre than semolina pasta. Higher EWP content increased optimum cooking time, firmness, tensile strength and elongation (P ≤ 0.05) and decreased cooking loss. Scanning electron micrographs showed that the EWP created a strongly continuous protein network. An increase in water reduced cooking time and firmness but increased cooking loss (P ≤ 0.05). Firm and elastic cooked MBB pasta was obtained under conditions of high EWP and low moisture content.
