4种海洋贝类多糖提取和保湿性研究

以马氏珠母贝(Pinctada martensii)、企鹅珍珠贝(Pteria penguin)、翡翠贻贝(Perna viridis)和近江牡蛎(oyster)的内脏团为原料提取、纯化多糖,与甘油、聚乙二醇400(PEG-400)、丙二醇和1,3-丁二醇四种常规保湿剂进行比较.结果表明,在相对湿度为44%时,前12h 吸湿率顺序为:马氏珠母贝<近江牡蛎<企鹅珍珠贝<翡翠贻贝< PEG-400<1,3-丁二醇<甘油<丙二醇;在相对湿度为80%时,前12 h 吸湿率顺序为:近江牡蛎<马氏珠母贝<企鹅珍珠贝<1,3-丁二醇<翡翠贻贝< PEG-400<甘油<丙二醇.前12 h 的保湿率顺序为:近江牡蛎>翡翠贻贝>马氏珠母贝>企鹅珍珠贝>甘油>1,3-丁二醇>丙二醇> PEG-400.翡翠贻贝吸湿性多糖优于其他贝类多糖,稍低于常规保湿剂.在相对湿度为80%时,前12 h 翡翠贻贝多糖的吸湿率大于常规保湿剂1,3-丁二醇,翡翠贻贝多糖保湿性稍弱于近江牡蛎,但强于其他贝类多糖和常规保湿剂要强一些

Moisture Absorption and Retention of Plysaccharides from Four Marine Shellfishes

Polysaccharides were obtained from the whole viscera of marine shellfishes Pinctada martensii,Pteria penguin,Perna viridis and Crassostrea rivularis by hot water extraction.Moisture absorption of the polysaccharide extractions from the four shellfishes were evaluated in contrast with traditional humectants such as glycerol,1,3-butanediol,propanediol,PEG-400.At a relative humidity of 44%,the order of moisture absorption rate at 12 hours of the humectants was as follows: Pinctada martensii < Crassostrea rivularis < Pteria penguin < Perna viridis < PEG-400 < 1,3-butanediol < glycerol < propanediol.At a relative humidity of 80%,the order of moisture absorption rate at 12 hours of the humectants listed as follows: Crassostrea rivularis < Pinctada martensii < Pteria penguin < 1,3-butanediol < Perna viridis < PEG-400 < glycerol Perna viridis > Pinctada martensii > Pteria penguin > glycerol > 1,3-butanediol > propanediol > PEG-400.Moisture absorption rate of polysaccharide from Perna viridis was superior to the other shellfishes,and inferior to traditional humectants.Moisturizing retention rate of polysaccharide of Perna viridis was inferior to oyster,and superior to the others.
