(1–3)(1–6)‐β‐Glucan‐enriched materials from Lentinus edodes mushroom as a high‐fibre and low‐calorie flour substitute for baked foods

(1–3)(1–6)‐β‐Glucan‐enriched materials from Lentinus edodes mushroom as a high‐fibre and... BACKGROUND: Extensive physiological and biological emphasis has been placed on pharmaceutical and medicinal uses of mushrooms containing β‐glucans, but their incorporation into processed functional foods is quite limited. Thus, low‐grade Lentinus edodes mushrooms were utilised to produce β‐glucan‐enriched materials (BGEMs), which were evaluated as a high‐fibre and low‐calorie substitute for wheat flour. RESULTS: The fractions obtained from Lentinus edodes mushrooms contained 514 g kg−1 of (1–3)‐β‐glucans with (1–6)‐β‐linked side chains and the chemical structure was confirmed by 13C NMR and FTIR spectroscopy. Replacement of a portion of the wheat flour with BGEMs resulted in the solutions with lower values of pasting parameters and also caused significant changes in starch gelatinisation. When BGEMs were incorporated into cake formulations, batter viscosity increased with more shear‐thinning behaviours and elastic properties improved. Overall, the cakes containing more BGEMs showed decreased volume and increased hardness while no significant differences were observed between the control and BGEM cakes containing 1 g of β‐glucan per serving. CONCLUSION: As a wheat flour substitute, the BGEMs that were prepared from low‐grade Lentinus edodes mushrooms, could be successfully used to produce cakes containing 1 g of β‐glucan per serving with quality attributes similar to those of the control.

Abstract

BACKGROUND: Extensive physiological and biological emphasis has been placed on pharmaceutical and medicinal uses of mushrooms containing β‐glucans, but their incorporation into processed functional foods is quite limited. Thus, low‐grade Lentinus edodes mushrooms were utilised to produce β‐glucan‐enriched materials (BGEMs), which were evaluated as a high‐fibre and low‐calorie substitute for wheat flour. RESULTS: The fractions obtained from Lentinus edodes mushrooms contained 514 g kg−1 of (1–3)‐β‐glucans with (1–6)‐β‐linked side chains and the chemical structure was confirmed by 13C NMR and FTIR spectroscopy. Replacement of a portion of the wheat flour with BGEMs resulted in the solutions with lower values of pasting parameters and also caused significant changes in starch gelatinisation. When BGEMs were incorporated into cake formulations, batter viscosity increased with more shear‐thinning behaviours and elastic properties improved. Overall, the cakes containing more BGEMs showed decreased volume and increased hardness while no significant differences were observed between the control and BGEM cakes containing 1 g of β‐glucan per serving. CONCLUSION: As a wheat flour substitute, the BGEMs that were prepared from low‐grade Lentinus edodes mushrooms, could be successfully used to produce cakes containing 1 g of β‐glucan per serving with quality attributes similar to those of the control.
