Ceramide is a sphingolipid, which provides health benefits. Gas chromatography coupled with flame ionized detector (GC-FID) was developed for targeted analysis of hydrolyzed ceramide in color rice and by-products. Method validation was done by means of linearity, repeatability and % recovery. R2 of 0.99 by means of linearity equation of the method was obtained. The recovery was in the range of 69.85 – 108.73% with RSD of normalized peak area lower than 10%. Hydrolyzed ceramide was found in unpolished rice, both glutinous and non-glutinous rice and its by-products including, defatted rice bran, rice bran wax and rice bran oil. The relationship between varieties of rice color and ceramide content was classified using principal component analysis (PCA) into 2 groups, including dark and pale color rice group. The highest levels of hydrolyzed ceramide as 21.11±0.02 mg/100 g was found in Mali Nil Surin (MNS), black non-glutinous rice. Whereas white non-glutinous rice named Seebukantang (SBK) contained the lowest content of hydrolyzed ceramide as 12.69±0.03 mg/100 g. The amount of ceramide in by-products found in defatted rice bran, rice bran oil and rice bran wax were 17.43±0.38, 14.67±0.16 and 12.54±0.41 mg/100 g, respectively.

The effect of phospholipase A1-catalyzed degumming on the phosphorus content, the retention rate of oryzanol, and total tocopherols and tocotrienols of dewaxed rice bran oil was investigated with comparison to water degumming and citric acid degumming. The fatty acid composition of dewaxed rice bran oil was also studied by gas chromatography. The phosphorus content of dewaxed rice bran oil after phospholipase A1-catalyzed degumming could be decreased from 332.5 mg·kg−1 to 9.3 mg·kg−1 with the citric acid dosage of 0.10%, high shearing rate of 23000 rpm, chelation time of 60 min, NaOH dosage of 1.5 mole equivalent to the amount of citric acid, reaction temperature of 50°C, and total water dosage of 2.5%, while the phosphorus content of dewaxed rice bran oil after water and acid degumming was 120.5 mg·kg−1 and 66.4 mg·kg−1, respectively. The retention rate of oryzanol and total tocopherols and tocotrienols was 97.58% and 96.81% for phospholipase A1-catalyzed degumming, 91.44% and 85.98% for water degumming, and 92.85% and 87.75% for acid degumming. There was no obvious change in fatty acid composition. The results indicated that phospholipase A1-catalyzed degumming was an effective method since it could decrease the phosphorus content to the required level and provide high retention rate of oryzanol and total content of tocopherols and tocotrienols without obvious change of fatty acid composition.

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.
