ovum (RCO) is the major waste/by-product of . This study investigated physicochemical characteristics and stability of emulsified ovum oil (RCOO) with ovum protein isolates (RCOPI) by particle size, zeta potential, scanning electron microscopy (SEM), visual appearance, confocal laser scanning microscopy (CLSM), rheology and antioxidant capacity. The emulsified RCOO demonstrated great stability, antioxidant capacity and rheological properties. The potential application of the emulsified RCOO as a delivery system was studied using quercetin as an example. The stability of encapsulated quercetin was investigated through storage stability, thermal stability and photostability. The bioaccessibility of encapsulated quercetin was explored by digestion simulation experiments. The results showed the stability and bioaccessibility of quercetin encapsulated in emulsified RCOO was greatly improved. This study showed that the emulsified RCOO is a promising edible delivery system for hydrophobic bio-actives.
卵油（RCO）是……的主要废弃物/副产品。本研究通过粒径、zeta电位、扫描电子显微镜（SEM）、外观、共聚焦激光扫描显微镜（CLSM）、流变学和抗氧化能力，研究了卵清蛋白分离物（RCOPI）乳化卵油（RCOO）的理化特性和稳定性。乳化后的RCOO表现出良好的稳定性、抗氧化能力和流变学性质。以槲皮素为例，研究了乳化RCOO作为递送系统的潜在应用。通过储存稳定性、热稳定性和光稳定性研究了包封槲皮素的稳定性。通过消化模拟实验探究了包封槲皮素的生物可及性。结果表明，乳化RCOO中包封的槲皮素的稳定性和生物可及性得到了极大提高。本研究表明，乳化RCOO是一种有前途的用于疏水性生物活性物质的可食用递送系统。
