A polysaccharide fraction obtained from camelina cake (CCP), selected as a carrier to encapsulate purple corn cob extract (MCE), was investigated. A wide population of carbohydrate polymers (with a polydispersivity index of 3.26 ± 0.07 and an average molecular weight of about 139.749 × 103 ± 4.392 × 10 g/mol) with a gel-like behavior and a thixotropic feature characterized the fraction. MCE-CCP combinations (50-50 and 25-75, /), selected based on CCP encapsulation efficiency, were tested for their stability and MCE polyphenols' bioaccessibility during digestion (monitored using an in vitro static procedure). During the oral and gastric phases of the digestion process, CCP gradually swelled and totally released MCE polyphenols. MCE-CCP50 had the fastest release. Moreover, anthocyanins were still detectable during the duodenal phase, in both MCE-CCP ingredients. Furthermore, CCP (5 mg/mL) exerted in vitro potential hypocholesterolemic activity via bile salts binding during digestion.
研究了从亚麻荠籽饼（CCP）中获得的一种多糖级分，该级分被选作载体用于包封紫玉米芯提取物（MCE）。该级分具有大量具有凝胶状行为和触变性特征的碳水化合物聚合物（多分散指数为3.26±0.07，平均分子量约为139.749×10³±4.392×10 g/mol）。基于CCP包封效率选择的MCE-CCP组合（50-50和25-75，/），在消化过程中（使用体外静态程序监测）测试了它们的稳定性和MCE多酚的生物可及性。在消化过程的口腔和胃阶段，CCP逐渐膨胀并完全释放MCE多酚。MCE-CCP50的释放速度最快。此外，在十二指肠阶段，两种MCE-CCP成分中的花青素仍可检测到。此外，CCP（5 mg/mL）在消化过程中通过结合胆汁盐发挥体外潜在的降胆固醇活性。
