外文摘要：To investigate the effect of steam processing on the form, structure and biological properties of selenopolysaccharides in the Chlamys nobilis, we conducted purification and compositional analysis of both raw and steamed samples. The results showed that the raw (SS-3) and steamed (SZ-3) groups had the highest selenium content in the purified fraction. Comparison of the structural characterization shows that selenium can exist in both O-Se-O and Se-O-C chemical bonds, but the absorption strength of the chemical bonds decreased after steam treatment, and steaming can convert beta-type pyranose to alpha-type in selenopolysaccharides. In vitro simulation of gastrointestinal digestion, SZ-3 fractions showed a higher bioaccessibility compared to SS-3 fractions, and also the cellular transport and uptake rates of selenium SZ-3 > SS-3 > sodium selenite were significant in the Caco-2 cell model. In conclusion, steaming can alter the structure and selenium content of selenopolysaccharides without affecting their bioavailability.
