Roasting Temperature

The effects of bran roasting temperature (160-200) °C and time (5-35 min) on the yield and quality attributes of 'Ofada' rice bran oil were studied so as to optimize the processing conditions for maximum oil yield with least deterioration of qualities. The physico-chemical parameters of oil studied included: yield, free fatty acids, peroxide value and colour, which were recorded as 14.50%, 5.80% (as oleic), 8.25 meq / kg and 1.51 abs, respectively. The optimum conditions were 200 °C roasting temperature and 15 min roasting time. With increasing the roasting temperature from 160-200 °C and the time 5-35 min, the oil yield and colour increased 11.31-14.50% and 1.51-1.58 abs, respectively, while free fatty acid and peroxide values decreased from 12.75-5.80% and 13.75-8.25 meq / kg, respectively.

The Impact

Rice bran oil has great benefits over other edible oils due to its unique antioxidant, oryzanol. There are many techniques employed for the extraction of rice bran oil. This research examined the impact of hydrothermal pretreatment (oC/min) before screw press extraction on physico-chemical quality attributes of rice bran oil such as peroxide value (meq O2/ Kg oil), acid value (mg KOH/g oil), free fatty acid (% olecic acid), tocopherol (µg/g), FRAP ferric reducing antioxidant power (mg FeSO4/g), DPPH radical scavenging activity (%), ?-oryzanol content (mg/g) and oil extraction yield (%). Our results revealed that rice bran should be heated at 120 oC for 8 min before screw press extraction to obtain the best physico-chemical and antioxidant qualities of rice bran oil. By this investigation, the economic value of rice bran would be improved significantly as a valuable input for food and pharmaceutical industry, instead of mono utilization as by-product for feed. Consumers would have better chance to improve their health via a green phytochemical food.

Gamma Oryzanol

Background and Objectives: For a long time, Asian women have known to use rice water, rice bran for skin care, lightening dark spots and slowing down the aging process. Gamma Oryzanol, an ester mixture of trans-ferulic acid with phytosterols and triterpene alcohols extracted from rice bran oil, has been shown to have beneficial effects on the skin, especially its antioxidant and anti-aging effect. The aims of this research were to formulate Gamma Oryzanol-loaded anti-aging cream and to evaluate the product quality. Materials and Methods: Gamma Oryzanol was imported from Japan. Some formulation parameters such as emulsifi-ers, performance modifiers were investigated and the product quality was evaluated according to the criteria of drugs and cosmetics. Results: The excipients were chosen including 1% (w/w) of Lunamer with 3% (w/w) of Prolipid as emulsifiers and 8% (w/w) of mango seed butter as a state modifier in the formulation of Gamma Oryzanol anti-aging cream. The cream is ivory-white, thick, smooth, fragrant-smelling and satisfied all criteria of developed specification. Conclusion: The study was successful in the preparation of Gamma Oryzanol anti-aging cream. Key words: Gamma Oryzanol, anti-aging cream, Franz cells.
