| 英文摘要 | Pyropia yezoensis is one of the most economical seaweed species in China. Determining how to make full use of mature P. yezoensis and exploring new ways to increase the value of its resources are important subjects of research for the development of the laver breeding industry. In this study, we provide a simple method to comprehensively extract the bioactive substances from P. yezoensis. The characteristics,functional properties, and antioxidant activities of two types of biopolymer extract from P. yezoensis were studied and analyzed relatively. Based on the characterization of water-soluble concentrate(WSC) and alkali-soluble concentrate(ASC), obtained via chemical analysis, including Fourier Transform Infrared Spectrometer(FT-IR) and Thermal Gravimetric Analyzer(TGA), and dif ferential scanning calorimetry(DSC), they both had typical polysaccharide and protein characteristics and steady composition. ASC showed higher nitrogen solubility, water holding capacity, and foaming ability. ASC could not only be used as a protein supplement, but also performed well in improving the properties of foods in terms of water holding and fat-absorption. The emulsifying activity and oil-holding capacity of WSC were observed to be higher than those of ASC. Thus, WSC has the potential to be used as an emulsifier. Surprisingly, WSC and ASC have radical scavenging capacity in vitro, which broadens the direction of their application. |
