A comparative study on the physio‐chemical properties, antioxidant and immuno‐stimulating activities of two national geographical indication products of Tremella fuciformis in China

Abstract

This study has focused on the systematic comparison of the two GI products grown in Gutian in Fujian Province (TF‐GT) and Tongjiang in Sichuan Province (TF‐TJ) in China. Chemical composition, rehydration ratio, viscosity and antioxidant and immuno‐stimulating activities of T. fuciformis were carefully compared. TF‐GT and TF‐TJ can be separated via cluster analysis, suggesting that a link between the qualities of GI products of T. fuciformis and its original place of production can be found out. Understanding these different properties are vital to product processing and dietary guideline formulation.

Investigating the Respiratory and Energy Metabolism Mechanisms behind ε-Poly-L-lysine Chitosan Coating’s Improved Preservation Effectiveness on Tremella fuciformis

“…Rich in gelatinous substances, amino acids, minerals, and other nutrients, T. fuciformis possesses medicinal and health benefits, including blood sugar reduction, lipid-lowering, immune modulation, anti-aging effects, and antiviral effects [ 3 ]. China, a major producer and consumer of edible fungi, with a diverse variety and a long history of mushroom cultivation, leads the world in terms of both cultivation area and production of T. fuciformis [ 4 , 5 ]. Owing to its high water content, lack of protective cuticle, and active respiration during storage, fresh T. fuciformis is particularly prone to moisture loss, nutrient decomposition, spoilage, and the production of toxic substances, thus losing its edible and economic value [ 6 ].…”

“…T. fuciformis has been demonstrated to be widely distributed in the world, including Brazil, China and other East Asian countries ( Wu et al, 2019 ; Zhang et al, 2023 ). There are two major production regions of T. fuciformis in China, Gutian in Fujian Province and Tongjiang in Sichuan Province, respectively ( Huang et al, 2021 ). In particular, the production of T. fuciformis from Fujian province accounts for 90% of the total production in China.…”
