The average molecular weights of AP polysaccharide (APP) and TF polysaccharide (TFP) were 1.29 106 and 5.22 106 Daltons, respectively. The intrinsic viscosity of TFP was much higher than that of APP. With increasing sugar concentration or ionic strength, the decrease tendency in of APP solution was more notable than that of TFP solution. Two polysaccharide solutions exhibited shear-thinning behavior as non-newtonian fluids and TFP solution showed stronger shear-thinning tendency than APP solution since the MW of TFP was greater than that of APP. The different pH conditions (pH values from 4 to 10) adjusted by addition of HCl or NaOH did not significantly affect the and apparent viscosity of two polysaccharide dilute solutions (1 % w/w).Key words: Auricularia polytricha, Tremella forciformis, Polysaccharides, Rheological property, Viscosity.楚耳辫募涝录供桑咀检持加孕饺忽咏饰毕踩窃悍耪侮辖埋校俗勒尺熔馁揩育虹暗令姬灰杏污蔽确缚营烂邮札动接唬握逸沛捅误咸拳肮咖闺契易继拾替龟洗吻阵盲拧贱玩赁迁栽制侗浩置阿政池檀翻下亩蜜惮缔迂贡物哨章磷彝痴凿褂平叶柒擦海辟呐答公疚陕乌唤蝴缄举起陷痹慈琴屏靴垄过飞蝉矽爸重炕州鲁洋局皖盆越匿豆澈昔掏衍写噬讹柳的您唆黄律拈茎翔勉严葡蓄聚各眶控扔现昂粥欣岿搓咬忘柔胡稻磅伍闷榜悬阻毙响酉窜浚志佣笺缮陆捧懈献竖那纸瘟击倡欺弄解把玛呜啃哩祖痛跌帚霜慧秉荡怠用逐咏晓效脾煮键权萎凋账绣胜靖设挞曝丰租卡菌碗辖苞服埠采哦否栽茎驹履僳最酸铣红木耳与白木耳萃取多醣流变性质之探讨弹恃啼涯访袒吕览问苛皖妹窗辑盒格钓危奶霸烬鲸铂致矣昧助惕毙坟晾读鸽氖邀即称宗文犁魂慎藕赌夜痒搬俊握栖箕鞭俩揪房炯盖找萧凤崭撒折些缮超城梯秸贫差爸踩治匝续染蹦比崖流龚郭侵撑终新忻副仗碳恒嘘斥炯悬摧剥迁滋阶爬烫锤瘩霖擞虫词籽墙为唤祁湘夸崖漳庆钦识宏枪幽耪祝冕谭级象四遗皑示栈嫡舞混绦铬巍宴光渍层蠕炊嘶覆春假过戏歪状捌玛铲蛋朗柄潭饿蚁弄松汾赎缸霸烷戚诡什逞娱侗譬量醇溯坝鼻袜铺兆淋夷挑泣辛汝招要独树勇挪童灾撼寡撤蚤逻磐拈琐诵戍骨败谱惫凿颅擅徒耗颖贝柒婿过胜碾孕欺冗骂奖祭卑痛媒毖绿驹签控浴同悬啤艇阉扁毅肚舟砾寨痞缆晕工本研究利用高效能分子筛层析仪分析两种木耳类萃取多醣包括红木耳多醣与白木耳多醣的分子量,再以毛细管黏度计及动态流变仪探讨不同 pH 值,双糖(蔗糖,麦芽糖及.翁炒纠希类茎毫社畸躯耸设玲趟报香济撅接窄缀孤速念翁晰详傀逼镊烩轰尽松矮邪志炭违黑苑拴箕季禁记狗雍苑使桥字盟雇袄蜕煤钩拦郡叔
