Cerumen is a mixture of beeswax and plant resin made by stingless bees. It has antimicrobial and antioxidant properties and is often used in biological and therapeutic treatments. However, its adhesive characteristic makes cerumen challenging to process into powder.
This study investigated the physical characteristics and antioxidant activity of the encapsulated freeze-dried dewaxed cerumen of . The combination of coating materials at concentrations of 20%, 30% and 40% and carrier ratios of maltodextrin to gum arabic of 9:1, 5:5 and 3:7 were used to encapsulate dewaxed cerumen when freeze-dried; the control was maltodextrin at a concentration of 31.25%.
All carrier matrices showed high yields of >80% and similar powder characteristics of low moisture content, low water activity, high glass transition temperature and water dispersibility. Overall, antioxidant activities ranged from 69-80%, while the encapsulation efficiency of total phenolic content ranged from 46-68%. All carrier matrices show higher antioxidant activities than 31.25% maltodextrin, with the lowest antioxidant at 57%.
The carrier ratio of 5:5 resulted in better physical properties and retained 68% of polyphenolic activity in powders.
蜂蜡是无刺蜂分泌的蜂蜡和植物树脂的混合物。它具有抗菌和抗氧化特性，常用于生物和治疗处理。然而，其粘性特征使得将蜂蜡加工成粉末具有挑战性。
本研究调查了[具体名称]的包封冻干脱蜡蜂蜡的物理特性和抗氧化活性。在冻干时，使用浓度为20%、30%和40%的包衣材料组合以及麦芽糊精与阿拉伯胶的载体比例为9:1、5:5和3:7来包封脱蜡蜂蜡；对照组为浓度为31.25%的麦芽糊精。
所有载体基质的产率均高于80%，且具有相似的粉末特性，即低水分含量、低水分活度、高玻璃化转变温度和水分散性。总体而言，抗氧化活性范围为69 - 80%，而总酚含量的包封效率范围为46 - 68%。所有载体基质的抗氧化活性均高于31.25%的麦芽糊精，最低抗氧化活性为57%。
5:5的载体比例产生了更好的物理性质，并在粉末中保留了68%的多酚活性。
