Fraction From Rice Bran Oil Using Ultrasonic Methods and Analysis Of Antioxidant Effectiveness

Abstract

Rice (Oryza sativa) is one of the main cereals in the world, especially in Asian countries. Rice bran, one of the byproducts of rice dehulling, has gained a lot of popularity as a functional foodstuff in recent years. The purpose of this study was to extract Ferulic Acid from the phenolic fraction of rice bran oil using the ultrasonic method, followed by antioxidant effectiveness analyses. Oil was extracted from rice bran using the ultrasonic method in an ethanol solvent. The result was analyzed for phenol yields, and contents and the variables tested include concentrations and volumes of ethanol. Furthermore, Antioxidant effectiveness tests were carried out on the highest yields of FA. The results showed the highest yield, 24%, was achieved at an ethanol concentration of 80%, the volume of 200 ml, and 25 grams of rice bran. The ferulic acid content in the phenolic fraction of rice bran oil was 10-20% with the highest Antioxidant Effectiveness of 10.71%.

Estimation of ferulic acid from selected plant materials by Spectrophotometry and High performance liquid chromatography

“…The present study showed that rice bran yielded a higher amount of FA than bamboo shoot and wheat bran. Recent studies also unveiled the fact that rice bran is a rich source of antioxidant molecules such as γ-oryzanol and ferulic acid (Arumsari et al, 2019;Tam et al, 2021). The extraction of Ferulic acid has been found much attention nowadays because it exhibits a wide variety of biological activities, including antimicrobial, antiinflammatory, anti-thrombosis, anticancer, and antioxidant activities.…”

Kinetic parameter for scale-up and γ-oryzanol content of rice bran oil as antioxidant: Comparison of maceration, ultrasonication, pneumatic press extraction

“…According to Ref. [ 2 ], rice bran oil is highly nutritious and contains unsaturated fatty acid and antioxidants like oryzanol, to-copherol, tocotrienol, phytosterol, polyphenol, and squalene. Ferulic Acid (FA) is a part of phenol fraction with the highest yield of 24 % at 80 % ethanol concentration and Ultra-sonication extraction method.…”

“…Rice to be consumed must first be separated from the skin, which can produce solid waste. Solid waste from rice separation is referred to as rice bran [1] [2]. Generally, the rice bran produced from the rice milling process is as much as 8-12%.…”
