Abstract
Rice is an important food crop throughout the world. Rice bran, the outer layer of rice grain, is a by-product generated during the rice milling process. Rice bran oil (RBO) is extracted from rice bran and has also become increasingly popular. RBO is considered to be one of the healthiest cooking oils due to its balanced proportion of fatty acids, as well as high content of γ-oryzanol together with phytosterols, vitamin E, wax ester, trace and macro elements, carotenoids, and phenolics. The existence of these compounds provides RBO with various functions, including hypotensive and hypolipidemic functions, antioxidant, anticancer, and immunomodulatory functions, antidiabetic function, anti-inflammatory and anti-allergenic functions, hepatoprotective activity function, and in preventing neurological diseases. Recently, research on the nutrients in RBO focused on the detection of nutrients, functions, and processing methods. However, the processing and utilization of rice bran remain sufficiently ineffective, and the processing steps will also affect the nutrients in RBO to different degrees. Therefore, this review focuses on the contents and nutritional functions of different nutrients in RBO and the possible effects of processing methods on nutrients.

Abstract
Thermal stability and antioxidant ability of γ-oryzanol in oil have been widely studied. However, further research is needed to explore its thermal degradation products and degradation pathways. The thermal degradation products of γ-oryzanol in stripped soybean oil were identified and quantified by employing high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) during heating at 180 °C. The results revealed that γ-oryzanol undergoes ester bond cleavage to form trans-ferulic acid and free sterols, and trans-ferulic acid generated intermediate compound 4-vinylguaiacol, which ultimately generated vanillin. Analysis of kinetic and thermodynamic parameters revealed the thermal stability ranking of the four components of γ-oryzanol as follows: CampFA > CAFA > 24MCAFA > SitoFA. Furthermore, γ-oryzanol exhibited superior antioxidant activity at lower temperatures. The results of this study provide a theoretical basis for a better understanding of the thermal stability and antioxidant properties of γ-oryzanol in oil under thermal oxidation conditions.

Unleashing the bioactive potential of Capsicum chinense cv Bhut Jolokia: a comparison of microwave- and ultrasound-mediated extraction techniques for lipophilic capsaicin. Nat Prod Res 2023:1-10. [PMID: 37787031 DOI: 10.1080/14786419.2023.2260066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Accepted: 09/10/2023] [Indexed: 10/04/2023]
Abstract
This study investigated the extraction of capsaicin from Capsicum chinense cv Bhut Jolokia using rice bran oil (RBO) as a 'green solvent' via microwave- and ultrasound-mediated techniques (MME and UME) as an alternative to hazardous organic solvents. Extraction conditions were optimised using MME at 180 and 300 W for 2 and 8 min and UME at 300 and 400 W for 10 and 30 min. The maximum capsaicin yield obtained was 12.47 mg/mL, with a corresponding gamma oryzanol content of 8.46 mg/mL. The peroxide value of the extract (capsaicin-infused RBO) was found to be within permissible limits as per Codex Alimentarius specifications. Results strongly suggest the potential of RBO as a novel solvent for extraction of capsaicin. The capsaicin-enriched oil can be used as a functional food ingredient due to its health-promoting properties.
