Formulation of functional noodles by adding Lentinus edodes mushroom powder: Physiochemical attributes, cellular mineral uptake and improved glycemic index

Abstract

This study investigated the physicochemical, low glycemic index, and mineral uptake of functional noodles added with varying concentrations (0–10 %) of Lentinus edodes (also known as shiitake) powder. Noodles with 4 % mushroom powder (L3) exhibited comparable sensory attributes in comparison with control noodles. The L3 showed significantly higher protein (1.92 ± 0.035 %), decreased carbohydrate content, improved cooking characteristics. The L3 exhibited darker color with lower hardness, adhesiveness, higher mineral content and bioavailability of iron (59.22 ± 0.49 %). As well, L3 showed a significantly higher mineral transport, retention, and uptake of minerals followed by increased ferritin content (29.17 ± 0.52 ng/mg cell protein). Mushroom powder incorporation in noodles significantly decreased the area under the curve of reducing sugar release correlating with lower glycemic index and thus a potential impact on blood sugar levels. This study illustrates the efficacy of mushroom powder as a functional component in noodles, offering both augmented nutritional advantages and increased glycemic regulation.
