外文摘要：To investigate the effect of steam processing on the form, structure and biological properties of selenopolysaccharides in the Chlamys nobilis. 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 could convert β-type pyranose to α-type in selenopolysaccharides. The results of the in vitro simulation of gastrointestinal digestion showed a higher bioaccessibility of the SZ-3 fractions compared to SS-3, 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. ? 2024, The Authors. All rights reserved.
