Evaluation of cooking characteristics, textural, structural and bioactive properties of button mushroom and chickpea starch enriched noodles.

Abstract

The present study was conducted out to develop nutritionally enriched noodles by supplementing wheat flour with mushroom and chickpea starch at different concentrations and its effect on physico-chemical, bioactive, cooking, microbial and sensory properties, morphological and textural properties has been investigated. The prepared noodles contained high levels of protein, and low levels of carbohydrate, energy with the incorporation of mushroom flour and chickpea starch concentration. The lightness (L*) (71.79-53.84) decreased and yellowness (b*) (19.33-31.36) and redness (a*) (1.91-5.35) increased with the incorporation of mushroom flour and chickpea starch. The optimum cooking time decreased while as the water absorption capacity and cooking loss increased with increase in mushroom flour and chickpea starch concentration. The microstructure study and textural properties depicted the clear picture of protein network, with smooth outer surface, and the decrease in hardness with increased concentration of mushroom flour and chickpea starch. XRD and DSC results revealed that the prepared noodles contained more complete crystallites and high fraction of crystalline region and the linear increase in the gelatinization temperature with increase in composite flour concentration. The microbial analysis of noodles showed the decrease in microbial growth with the incorporation of composite flour.
