A short review of green extraction technologies for rice bran oil
Rice is one of the most important crops throughout the world, as it contributes toward satisfying the food demand of much of the global population. It is well known that rice production generates a considerable number of by-products, among which rice bran deserves particular attention. This by-product is exceptionally rich in nutrients, since it contains a wide spectrum of macronutrients
The search was performed by using relevant keywords such as rice bran oil, phytochemicals, phenolic compounds, terpenoids, steroids, oryzanol, tocotrienols and tocophenols. Other relevant keywords related to therapeutical potentials such as antioxidant, anti-inflammatory, antidiabetic, anticancer were used, with addition of the word rice bran oil.

The crude rice bran oil extracted using subcritical liquefied dimethyl ether extraction produced the highest total phenolic contents and antioxidant activities. The highest γ-oryzanol content of the crude rice bran oil was found in oil extracted by conventional cold press (1370.43 mg/100 g). The γ-oryzanol content of the oil obtained via
Green solvents and technologies for oil extraction from
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several
Their results show that it is possible to obtain a maximum oil yield of 20.05 g/100 g rice bran in a three-hour extraction in ethanol with 6% of water at 82.5 °C, with a 4:1 w/w solvent-to-bran ratio and a stirring speed of 137.5 rpm. The -. γ. oryzanol content varies between 1527 and 4164 mg/kg of fresh rice bran.
Effect of novel combination processing technologies on
Rice bran, a primary by-product from the rice processing industries, containing 10–15% oil, attracts significant attention from consumers due to its many health-promoting effects. The extraction methodology used is one of the most critical factors affecting the quality and yield of oil from rice bran.
Rice bran is a by-product of rice processing, obtained through the polishing of rice grain. It illustrates the high considerable oil content (between 15–25%) and it is considered as an excellent source of nutritionally beneficial compounds. Pressurized fluid extraction (PFE) technique was used for extraction of oil from rice bran.
Conventional and ultrasound-assisted extraction of rice bran
One of the most common rice bran applications is the extraction of rice bran oil, rich in γ-oryzanol, which has shown many health benefits including antioxidant, anti-inflammatory, and anti-hypercholesterolemic properties. Rice bran oil is usually extracted by organic solvents, which are toxic for health and the environment.
After rice harvesting, the milling processes generate many by-products including husk, bran, germs, and broken rice representing around 40% of the total grain. Bran, one of the external cereal layers, contains proteins, dietary fibers, minerals, and lipids. One of the most common rice bran utilization is the extraction of rice bran oil (RBO). Among all vegetable oils, RBO presents a unique
