1. Production of milk analogues from rice bran protein hydrolysate using the subcritical water technique
Abstract Subcritical water treatment is a useful technique for the extraction of active compounds from biomass materials due to its short processing time, low cost, and environmental sustainability. Defatted rice bran is a by-product of rice bran oil, which still contains protein. In this study, rice bran protein was extracted using subcritical water treatme

2. LIPASE PRODUCTION BY Aspergillus niger GROWN IN DIFFERENT AGRO-INDUSTRIAL WASTES BY SOLID-STATE FERMENTATION
ABSTRACT Filamentous fungi can easily degrade agro-industrial wastes in solid-state fermentation processes, synthesizing many important commercial biocompounds, such as lipolytic enzymes. The aim of this study was to evaluate the effect of the composition of the solid culture medium on the production of lipolytic enzymes by the fungus Aspergillus niger. Rice

3. The influence of extraction methods on composition and antioxidant properties of rice bran oil
AbstractThe current study was employed to assess the influence of the different extraction methods on total tocols, γ-oryzanol content, and antioxidant properties of Chiang Mai Black rice, Mali Red rice, and Suphanburi-1 Brown rice bran oil. Rice bran oil (RBO) was extracted by Hexane, Hot pressed, Cold pressed, and Supercritical Fluid Extraction (SFe) meth

4. Concentration of trans-vaccenic and rumenic acids in the milk from grazing cows supplemented with palm oil, rice bran or whole cottonseed
The changes in the concentration of trans-vaccenic (C18:1t-11) and rumenic (C18:2c-9,t-11) acids in the milk from cows grazing on Pennisetum clandestinum, fed a supplement containing palm oil, rice bran or whole cottonseed were evaluated. Three supplements were assessed: one control supplement containing palm oil (C), with a low concentration of linoleic aci

5. Estudo da tecnologia de membrana polimérica aplicada ao processo de degomagem e desacidificação do óleo de farelo de arroz / Study of polymeric membrane technology applied to degumming and deacidification process of rice bran oil
O óleo de farelo de arroz, além de ser utilizado como alimento, é conhecido pelo seu atributo nutricional, devido a sua fração insaponificável rica em antioxidantes como os tocoferóis, tocotrienóis e em especial o ?-orizanol, que dão ao óleo uma maior resistência à oxidação e à deterioração. Além disso, diversos estudos mostram a habilidade

6. Protective effect of oryzanol isolated from crude rice bran oil in experimental model of diabetic neuropathy
Several studies have implicated the involvement of poor glycemic control and oxidative/nitrosative stress in the development of diabetic neuropathic pain, an important microvascular complication affecting more than 50% of diabetic patients. However, lack of understanding of the underlying etiology, development of tolerance, inadequate relief and possible tox

7. Anti-hyperlipidemic activity of oryzanol, isolated from crude rice bran oil, on Triton WR-1339-induced acute hyperlipidemia in rats
Experimental studies carried out for evaluating the anti-hyperlipidemic properties of rice bran components have given interesting but often contrasting results. Therefore, the current study was initiated to investigate the anti-hyperlipidemic activity of oryzanol (OZ), a commercially-important bioactive phytochemical, isolated from crude rice bran oil (cRBO)

9. Production of surfactin by bacillus subtilis mtcc 2423 from waste frying oils
One of the obstacles in the way of wide scale industrial application of biosurfactants is the high production cost coupled with a low production rate. In order to lower the production cost surfactin production by Bacillus subtilis MTCC 2423 was studied in submerged batch cultivation using waste frying oils. It was observed that the decrease in surface tensio

10. Proteção da gordura do farelo de arroz integral e o seu uso da alimentação de ruminantes / Rice bran oil protection and their use in ruminant feeding
Inicialmente, dois experimentos foram realizados para avaliar o efeito do tratamento com hidróxido de cálcio com diferentes veículos de aplicação sobre o extrato etéreo (EE) e os componentes não lipídeos do farelo de arroz integral (FAI) para uso como fonte de gordura protegida em ruminantes. O primeiro experimento foi conduzido num delineamento inte

11. Liquid-liquid equilibrium data for the system composed of refined rice bran oil / anhydrous ethanol / water / hexane / Determinação de dados de equilibrio liquido-liquido de sistemas contendo oleo de farelo de arroz refinado / etanol anidro / agua / hexano
The extraction of oil from rice bran aggregates value to the rice production. This oil has nutritional and nutraceutical properties, therefore, the interest of the industries in its use. The oil deacidification can be carried out by liquid¿liquid extraction with lower loss of neutral oil, mainly in the case of oil with high content of free fatty acid. In th
