Abstract

Rice bran has consistently been claimed to show good hypocholesterolemic property in animals Sharma and Rukmini 1986 Kahlon et.al. 1992 Nicolosi et.al. 1991 Kahlon et.al. 1996and human trials Hegsted et.al. 1992 and Gerhadt and Gallo 1998. However the bioactive components in the bran that provides this effect is still not confirmed. This study was carried out to examine the cholesterol lowering potential of local rice bran using rat animal model. Male Sprague-Dawley rats were fed diets containing 0.3 cholesterol 0.1 cholic acid with 10.0 total dietary fiber TDF either from de-fatted rice bran full-fat rice bran or cellulose. The rice bran used was from mixed local varieties Herbarium UKMBAZ 6807: MR 185 AZ 6808: MR211 AZ 6809: MR 29. Rats were fed for 3 weeks while cholesterol cellulose group was used as a control. Rats fed with full-fat rice bran rich in rice bran oil and fiber had lower 2.54 mmol/L plasma total cholesterol compared to de-fatted fiber rich group 3.48 mmol/L at the end of 3 week treatment. A comparison between these two plasma cholesterol levels with the cholesterol cellulose control group indicated that stabilized intact rice bran caused 36.5 plasma cholesterol reduction while de-fatted bran only gave 13 plasma cholesterol reduction. The oil in the intact bran has demonstrated higher reduction 23.5 when compared with full-fat and de-fatted diets. These observations indicate that Malaysian rice bran has equally good hypocholesterolemic effect as shown by other researchers Kahlon et.al. 1992 Sharma and Rukmini 1986. This result also indicates the potential of Malaysian rice bran as an alternative source for oil blend as well as fiber source in the future.
