Abstract

Rice bran oil (RBO) is an emerging cooking oil, known for its high level of bioactive compounds that play an important role in the management of different diseases. The RBO extraction methods directly impact the level of bioactives in RBO, resulting in alterations of therapeutic activities. The green extraction processes, including supercritical CO₂, subcritical CO₂ Soxhlet, subcritical liquefied dimethyl ether, enzyme-assisted aqueous, microwave-assisted, and ultrasound-assisted extraction, were applied to obtain RBO from rice bran. RBO exhibited potential health benefits via upregulation and downregulation of several types of molecular pathways and gene expression. In addition, the unique physicochemical properties of RBO enable its use in cosmetics, novel drug delivery systems, biosurfactant applications, and the development of moisturizing, detoxifying, and anti-aging products. Several novel formulations, such as nanoemulsions, emulgels, self-nanoemulsifying systems, and oleogels, were prepared in which RBO significantly improves solubility, bioavailability, and intestinal absorption of lipophilic drugs. Animal feed, biofuel, and food products are other applications of RBO. Considering all these aspects of RBO, this review was designed to explore the in-depth RBO extraction phenomenon, the molecular mechanism exerted by functional agents in RBO, and the emerging applications in diverse fields.

米糠油提取、活性食用油及新兴应用的最新趋势综述

米糠油（RBO）是一种新兴的食用油，以其高水平的生物活性化合物而闻名，在各种疾病的治疗中发挥着重要作用。RBO提取方法直接影响RBO中的生物活性水平，导致治疗活性的改变。采用超临界CO2提取、亚临界CO2索氏提取、亚临界液化二甲醚提取、酶助水提取、微波提取、超声提取等绿色提取工艺从米糠中提取RBO。RBO通过上调和下调几种类型的分子途径和基因表达显示出潜在的健康益处。此外，RBO独特的物理化学特性使其能够用于化妆品，新型药物输送系统，生物表面活性剂应用以及保湿，排毒和抗衰老产品的开发。制备了几种新型制剂，如纳米乳液、凝胶、自纳米乳化系统和油凝胶，其中RBO显著提高了亲脂性药物的溶解度、生物利用度和肠道吸收。动物饲料、生物燃料和食品是RBO的其他应用。考虑到RBO的这些方面，本文旨在深入探讨RBO的提取现象，功能剂在RBO中的分子机制，以及在各个领域的新兴应用。
