Effect of strains and extraction methods on β-glucan production, antioxidant properties, and ftir spectra from mushroom fruiting bodies of schizophyllum commune fr. In thailand

Abstract

Schizophyllum commune Fr., a native mushroom of Thailand, has a high nutritional value and is classified as a mushroom with medicinal properties that can neutralize the growth of many cancer cells. This research aimed to study the effect of S. commune strains and the extraction methods on the quantity and properties of β-glucan. The five S. commune Fr. strains used in this research consisted of Chanthaburi, 85-022, 85-023, 85-031, and 85-043. There were two different β-glucan extraction methods employed: hot water (M1) and hot alkali extraction (M2), which were compared with the control (native-MR). The results indicated that the Chanthaburi strain has the highest β-glucan content 49.20±0.35% (w/w), and high potential antioxidant activity (79.14±0.77 DPPH% and 50.92±0.48 ABTS%) (p < 0.05). The extraction methods did not affect the yield of β-glucan, except the antioxidant properties and chemical structure of the extract substance. The extract substance from M2 has significantly the highest potential antioxidant activity (80.22±0.51). A mushroom juice drink in cans was developed using 1-day-old MR and adjusted pH of more than 7, which can increase the antioxidant properties of the product.
