Pleurotus eryngii polysaccharide (PEP) was obtained using hot water extraction and ethanol precipitation. Three purified polysaccharide fractions (namely PEP1-A, PEP2-A and PEP3-A) were obtained from PEP using DEAE-cellulose-52 chromatography and a gel permeation Sephadex G-100 column. Firstly, this paper examined the characterisation of PEP1-A, PEP2-A and PEP3-A. The corresponding molecular weights were 5.378 9 10 5 , 9.506 9 10 6 and 4.975 9 10 5 Da, respectively. PEP1-A, PEP2-A and PEP3-A had similar monosaccharide compositions. PEP1-A was b-configuration, and PEP2-A and PEP3-A were a-configuration. PEP1-A, PEP2-A and PEP3-A had pyran-type rings, (1 ? 3) glucose and (1 ? 6) galactose linkages. Secondly, PEP, PEP1-A, PEP2-A and PEP3-A possessed antioxidant activities, and PEP was best. Therefore, only PEP was used to study its anti-fatigue activity in vivo. The result proved that PEP had anti-fatigue activity. PEP could be used as a valuable natural food supplement for preventing anti-fatigue or functional food.

“…Polysaccharides from mushrooms including Flammulina velutipes have been shown to have prebiotic, immunomodulatory, antioxidant, antitumour and learning and memory improving activities in mice (Dong et al, 2017;Su et al, 2018;Zhang et al, 2018;Zhao et al, 2018). Growing evidences show polysaccharides, especially those from plants, cannot be hydrolysed by human enzymes in the small intestines, stomach or saliva (Ding et al, 2017;Di et al, 2018).…”

Summary In this study, in vitro digestion and fermentation of Flammulina velutipes ‐derived polysaccharides (FVP) were investigated. It was found that FVP mainly consisted of 48.45% glucose, 15.40% mannose, 14.60% xylose, 11.80% fucose and 9.90% galactose. The ‐human saliva, simulated gastric and small intestinal juices conditions did not break down the FVP. Based on in vitro fermentation tests, FVP modulated the composition of gut microbiota by elevating the amounts of Bifidobacteriaceae and Bacteroidaceae and reducing the numbers of genera Lachnospiraceae and Enterococcaceae. Meanwhile, FVP affected the synthesis of short‐chain fatty acids derived from gut microbiota.

“…Mushroom polysaccharides (MP) consist of linear and branched glucans with different types of glycosidic linkages, such as (1→3), (1→6)‐β‐glucans, (1→3)‐α‐glucans, and heteroglycans, containing glucuronic acid, xylose, galactose, mannose, arabinose, or ribose . MP possess multiple biological activities including antioxidant, antimicrobial, immunomodulatory, and anti‐inflammatory effects . Previous studies done by research team from our lab could demonstrate that the molecular weight, monosaccharide composition, triple helical structures, sulfate, and uronic acid contents of MP were varied among different types of mushrooms .…”

Mushroom polysaccharides‐incorporated cellulose nanofiber films with improved mechanical, moisture barrier, and antioxidant properties

Mushroom polysaccharides (MP), including white MP, brown MP, and enoki MP, were incorporated into cellulose nanofiber (CNF). Studies on thermal property, structure, crystallinity, and morphology of CNF-MP films revealed that MP was well interacted with and adsorbed onto CNF. Incorporation of MP significantly (P < 0.05) increased tensile strength and reduced water vapor permeability of CNF film. CNF-MP films possessed higher antioxidant activity than CNF only or CNF-chitosan film, and the antioxidant activity of released components from CNF-MP films immersed in water was higher than that released from films immersed in methanol. Radical scavenging activity and reducing ability were major antioxidant mechanisms of CNF-MP films. These trends were consistent with the results of total phenolics content released from films and the antioxidant activity of MP themselves. This study demonstrated CNF-MP films may be used as packaging material for preventing oxidation and/or dehydration of food during storage.
