Rice bran wax is an important source of policosanol (PC). PC extracted from Thai bleached rice bran wax was used. The yield of extracted PC was 31.21 wt%. Policosanol organogels (PCOs) were prepared by mixing rice bran oil with PC extracted at the concentrations of 12, 13.5, and 15 wt%. It was determined that PCO prepared using the 15% concentration of PC exhibited the best properties, such as the oil-binding capacity, texture parameters, thermal behaviour, and solid fat content (SFC). The characteristics of PCOs were altered by the PC concentration (p < 0.05). PCOs exhibited dendrite-like crystals, which changed to spherulite crystals with an increase in the storage time. The emulsion produced from PCO at the 15% concentration of PC (PCE) showed emulsion stability. The results of this study show that PC extracted from Thai bleached rice bran wax are potential organogelators for organogels and can be used in W/O emulsions produced without the addition of an emulsifier or a stabilizer.

潜在使用泰国漂白米糠蜡中的二十四醇提取物作为有机胶凝剂

米糠蜡是波多固醇（PC）的重要来源。使用从泰国漂白米糠蜡中提取的PC。提取的PC的产率为31.21重量％。通过将米糠油与以12、13.5和15 wt％的浓度萃取的PC混合来制备波可醇有机凝胶（PCO）。已确定使用15％浓度的PC制备的PCO表现出最佳的性能，例如油结合能力，质地参数，热行为和固体脂肪含量（SFC）。PC浓度改变了PCO的特性（p <0.05）。PCO显示出类树状晶体，随着储存时间的增加，其变为球晶状晶体。由PC（PCE）浓度为15％的PCO生产的乳液显示出乳液稳定性。
