The extraction process of alcohol-insoluble polysaccharides from exhausted Moradyn cob ( L. cv. Moradyn) (EMCP), camelina cake ( L. Crantz) (CCP), and common bean seeds ( L.) (CBP) was investigated and optimized by Response Surface Methodology. Each fraction was tested at different core/carrier ratios in the encapsulation of Moradyn cob extract (MCE), a rich source of antioxidant anthocyanins, and the obtained ingredients were screened for their encapsulation efficiency (EE%) and extraction process sustainability. The ingredients containing 50% and 75% CCP had EE% higher than 60% and 80%, respectively, and were selected for further studies. Preliminary structural analysis indicated CCP was mostly composed of neutral polysaccharides and proteins in a random-coiled conformation, which was also unchanged in the ingredients. CCP-stabilizing properties were tested, applying an innovative stress testing protocol. CCP strongly improved MCE anthocyanins solid-state stability (25 °C, 30% RH), and therefore it could be an innovative anthocyanins carrier system.
采用响应面法对从 exhausted Moradyn 玉米芯（L. cv. Moradyn）（EMCP）、亚麻荠籽饼（L. Crantz）（CCP）和普通豆种子（L.）（CBP）中提取醇不溶性多糖的工艺进行了研究和优化。在富含抗氧化剂花青素的 Moradyn 玉米芯提取物（MCE）的包封过程中，对每个组分在不同的核/载体比例下进行了测试，并对所得成分的包封效率（EE%）和提取过程可持续性进行了筛选。含有 50%和 75%CCP 的成分的 EE%分别高于 60%和 80%，并被选作进一步研究。初步结构分析表明，CCP 主要由呈无规卷曲构象的中性多糖和蛋白质组成，在成分中也未发生变化。采用创新的应力测试方案对 CCP 的稳定性能进行了测试。CCP 显著提高了 MCE 花青素的固态稳定性（25℃，30%相对湿度），因此它可能是一种创新的花青素载体系统。
