Effect of novel combination processing technologies on extraction
Using solvents is the current commercial process for rice bran oil extraction, which has its setbacks. It is challenging and expensive, and there is a risk of traces of solvent residue in the oil. Emerging combination extraction technologies offer zero to minimal solvent residues or chemical deformation while considering increasing environmental and energy footprint.
In this technology, the cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001). In a previous study, Chen (2014) used alkaline protease to extract oil from rice bran and determined the optimal process parameters.
Bioprocessing Technology of Rice Bran Oil
Abstract. Development of commercial enzymes, such as phospholipases and lipases, has made bioprocessing of rice bran oil (RBO) an attractive option to produce good quality RBO. Enzymatic stabilizing of rice bran during storage has provided an alternative way of deactivating lipolytic enzymes, which affect the stability of RBO.
1. Introduction. Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%–20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids (Tao, 1989; Houston, 1972; Saunders, 1986).
Oil from Rice Bran and its Processing Technology
Oil from Rice Bran and its Processing Technology. September 2023. DOI: 10.1007/978-981-99-3224-5_4. In book: Science of Rice Chemistry and Nutrition (pp.55-74) Authors: Jinhu Tian. Changqing Wei.
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

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.
Review on Recent Trends in Rice Bran Oil Processing
The nutritional qualities and health effects of rice bran oil are also established. RBO is rich in unsaponifiable fraction (unsap), which contains the micronutrients like vitamin E complexes, gamma oryzanol, phytosterols, polyphenols and squalene. However, the high FFA and acetone-insoluble content of RBO made it difficult for processing.
The aim of this study is to review the innovative techniques based on bioprocessing, thermal or physical treatments which have been proposed during the last few decades to convert rice bran into a valuable food ingredient. Rice bran (Oryza sativa) is the main by-product of rice grain processing. It is produced in large quantities worldwide and it contains a high amount of valuable nutrients
- What are the technologies of rice bran oil?
- After that, the fatty acid composition, bioactive compounds, and the processing technologies of rice bran oil are described and the refining technology of rice bran oil (degumming, deacidification, dewaxing, etc.) as well as the technologies to remaining the bioactive compounds in rice bran oil are introduced.
- Can rice bran be treated with enzymes?
- Treating rice bran with enzymes is a new oil processing technology. In this technology, the cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001 ).
- What is rice bran?
- Rice bran is obtained from outer layer of the brown (husked) rice kernel during milling. It has emerged as potential by-product from rice processing industry due to the increasing demand for rice bran oil (RBO) as healthy functional food ingredients.
- How is rice bran oil extracted?
- There are about 15¨C20% crude oil in rice bran; normally, the rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction, and then refined by decolorization, deodorization, or other processes.
- What is rice bran oil (RBO)?
- This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in ¦Ã-oryzanol, a powerful antioxidant mixture of bioactive molecules.
- What is rice bran oil?
- Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (¦Ã-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
