This study aimed to enhance the content of slowly digestible starch (SDS) and resistant starch (RS) by designing a type of novel shell-controllable calcium alginate/curdlan/corn starch@calcium alginate (CA/CL/CS@CA) core-shell structured macrocapsule. These macrocapsules were obtained by coating calcium alginate/curdlan/corn starch beads with different concentrations of sodium alginate. The results of the swelling power indicated that as the concentration of sodium alginate in the shell increased from 0% to 0.5%, the swelling degree of the macrocapsules at 95 °C decreased from 5.64 ± 0.09 g/g to 4.30 ± 0.12 g/g. The in vitro digestion experiments indicated that the content of SDS and RS of the macrocapsules at a sodium alginate concentration of 0.5% reached 42.21 ± 1.04% and 28.82 ± 1.05%, respectively. These results suggest that the CA/CL/CS@CA core-shell structured macrocapsules have the potential to be used as functional foods for cardiovascular disease, diabetes, and obesity patients.
本研究旨在通过设计一种新型壳控型海藻酸钠/结冷胶/玉米淀粉@海藻酸钠（CA/CL/CS@CA）核壳结构大胶囊来提高缓慢消化淀粉（SDS）和抗性淀粉（RS）的含量。这些大胶囊是通过用不同浓度的海藻酸钠对海藻酸钠/结冷胶/玉米淀粉珠进行包衣获得的。溶胀能力的结果表明，当壳中海藻酸钠的浓度从 0%增加到 0.5%时，95°C 下大胶囊的溶胀度从 5.64±0.09 g/g 降低到 4.30±0.12 g/g。体外消化实验表明，海藻酸钠浓度为 0.5%时，大胶囊中 SDS 和 RS 的含量分别达到 42.21±1.04%和 28.82±1.05%。这些结果表明，CA/CL/CS@CA 核壳结构大胶囊有望成为心血管疾病、糖尿病和肥胖症患者的功能性食品。
