Studies on the Physicochemical and Processing Properties of Tremella fuciformis Powder

Abstract Tremella fuciformis is edible and medicinal food since ancient times in China. In this article, the physicochemical and processing properties of Tremella fuciformis powder (TFS) and synergistic interaction with Lotus seed powder (LTS) in aqueous solution were investigated. The elemental compositions of TFS were 1.71 % N, 47.21 % O, 40.35 % C, 6.25 % H and 0.20 % S. Aspartic and Glutamic acids were the major amino acids in TFS for taken about 0.91 % and 1.12 %. TFS dispersion couldn’t form a gel structure at all selected concentrations until the ratio of TFS: LTS was 1:1 at a total concentration of 36 mg/mL. The network strength of TFS/LTS dispersions increased with the total powder concentrations increased during continuous heating from 25°C to 70°C. Gluten, amorphous and crystalline regions, and amorphous starch were observed in mixtures TFS/LTS compared with TFS. TFS/LTS had a more concavo-convex microstructure than TFS due to starch gelatinization in LTS.
