油脂小体（OBs）是一种天然、稳定的油核微胶囊，其甘油三酯基质可以作为疏水分子的合适载体。虾青素具有很高的抗氧化性能，但对氧化非常敏感，导致其生物活性的丧失。结果研究了环境因素（光、氧、温度和pH）对花生油体制备虾青素微胶囊的物理稳定性和氧化稳定性的影响。贮藏14 d后，虾青素在花生油微胶囊（pom）中的保留率显著提高。光照条件下虾青素保留率高于黑暗条件下。真空贮藏过程中虾青素的保留率也显著提高。虾青素保留率在4°C时最高，pH为3.0时最低。结论微胶囊化可以提高虾青素的保留率和储存稳定性，重组OBs是虾青素包埋的理想壁材。©2022化工学会
BACKGROUNDOil bodies (OBs) are a kind of natural and stable oil nucleate microcapsule in which the triglyceride matrix can be used as an appropriate carrier of hydrophobic molecules. Astaxanthin has high antioxidant properties but is extremely sensitive to oxidation, causing the loss of its bioactive properties.RESULTSThe purpose of this study was to clarify the effects of environmental factors (light, oxygen, temperature, and pH) on the physical and oxidative stability of astaxanthin microcapsules prepared with peanut oil bodies (POBs). After 14 days of storage, the retention rate of astaxanthin in peanut oil microcapsules (POMs) was significantly increased. The astaxanthin retention rate of POMs stored under light conditions was higher than under dark conditions. Similarly, the retention rate of astaxanthin in POMs was significantly increased during vacuum storage. The astaxanthin retention rate was also the highest when POMs were stored at 4 °C, whereas it was the lowest at pH 3.0.CONCLUSIONThe experiment demonstrated that microcapsulation could improve the astaxanthin retention rate and storage stability, and recombinant OBs were potential ideal wall materials for astaxanthin embedding. © 2022 Society of Chemical Industry
