Oil from Rice Bran and its Processing Technology | SpringerLink
Deacidification is the process of removing free fatty acids from crude rice bran oil. The deacidification methods of rice bran oil include alkali refining, distillation, mixing, re-esterification, and extraction. The alkali refining method has comprehensive effects such as deacidification and decolorization, but the refining loss is much higher.
Crude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ-oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ-oryzanol.
Refining of high free fatty acid rice bran oil and its
M M Alam. Mahjabin Kabir. M. S. Rahman. ... Rice bran oils that have a percentage of free fatty acids ranging from 4% to 8% may reach 0.12% to 0.60% after refining (Rajan and Krishna, 2009). In
Results showed that the physical refining process was able to preserve 97% of γ-orizanol, and its presence improved the oxidative stability of the oil comparing with the commercial rice bran oil
Life cycle assessment of rice bran oil production: a case
Environmental problems caused by the food processing industry have always been one of the concerns for the public. Herein, for the first time, a gate-to-gate life cycle assessment (LCA) was employed to evaluate the environmental impact of rice bran oil production. Four subsystems, namely, transportation of the raw rice bran to oil factory, crude oil extraction, oil refining, and oil storage
Physical refining of rice bran oil (RBO) with acidity between 4.0 and 12.4% has been investigated in relation to degumming and dewaxing pretretments. It appears that physical refining after combined low-temperature (10°C) degumming-dewaxing produces good-quality RBO with respect to color, free fatty acid, oryzanol, and tocopherol content.
Rice Bran Oil
The steps that occur in a typical rice bran oil refining process, along with the by-products generated are given in Fig. 14.1. Generally, the first step in the refining process with crude rice bran oil is dewaxing or winterizing, although for other vegetable oils the dewaxing step can be done at different times in the refining process.
Therefore, the present study was conducted to evaluate the quality and oryzanol content during the crude RBO refining process. Crude RBO was obtained by the reflux method using n-hexane as a solvent, followed by the dewaxing process by cooling and filtering procedure.
Phytosterols and γ‐oryzanol in rice bran oils and distillates
Commercially available refined rice bran oil (RBO) contained high contents of phytosterol and γ-oryzanol, that is, 858–1034 and 248–887 mg per 100 g oil, respectively. Although the crude rice bran oil (CRBO) had high contents of both phytochemicals (1362–1376 mg phytosterol per 100 g and 1599–1666 mg γ-oryzanol per 100 g), physical
The rice bran oil contains about 2–3 % of wax, which can be separated, de-oiled, and bleached to form light-colored edible grade wax that can be used for food and pharmaceutical applications (Abhirami et al., 2020). The RBW has been effectively used in several food applications like forming oleogels and structured lipids, edible coating of
