Thymoquinone (TQ), a monoterpenoid quinone, is a major bioactive component of Nigella sativa L. seeds oil, which has been proven to have therapeutic and bioactive properties. The current study is carried out to investigate the encapsulation of N. sativa seeds oil containing TQ using the mixture of modified starch (MS) and maltodextrin (MD). In this regard, the effect of the different ratios of MS:MD on encapsulation efficiency (EE), TQ retention, and other characteristics of particles is investigated. The highest EE is observed in particles with 80:20 ratio of MS:MD powders achieving more than 90%, while the sample with 50:50 ratio of the wall materials has the maximum value of the retention of TQ (61.12%). The increase of MD ratio in formulations improves the wettability (<3 min) and solubility (>90%) of the particles, decreases the moisture up to 0.08%, and decreases the EE and TQ retention till 80% and 55%, respectively. The particles prepared with 50:50 ratio of MS:MD are the best particles with acceptable EE and better TQ retention is selected to evaluate the stability of TQ during the time. Results show that the encapsulation of N. sativa seeds oil considerably prevents the degradation of TQ during storage.

变性淀粉与麦芽糖糊精的混合物,用于喷雾干燥胶囊化含胸腺醌的黑变种种子油

百里醌(TQ)是一种单萜类醌,是带子种子油的主要生物活性成分,已被证明具有治疗和生物活性特性。当前的研究是为了研究紫花苜蓿的包封使用改性淀粉(MS)和麦芽糖糊精(MD)的混合物制成含TQ的种子油。在这方面,研究了MS:MD的不同比例对颗粒的包封效率(EE),TQ保留率和其他特征的影响。在MS:MD粉末比例为80:20的颗粒达到90%以上时,观察到最高的EE,而壁材料比例为50:50的样品具有最大的TQ保留值(61.12%)。制剂中MD比的增加改善了颗粒的润湿性(<3分钟)和溶解性(> 90%),将水分降低至0.08%,并将EE和TQ保留率分别降低至80%和55%。以50:50的MS:MD是具有可接受的EE的最佳颗粒,并且选择了更好的TQ保留率来评估TQ在这段时间内的稳定性。结果表明紫花苜蓿种子油可大大防止TQ在储存过程中降解。
