Oryzanol, % Re­quire­ment: Not less than one per cent

Oryzanol is a nat­u­ral an­tiox­i­dant and is known to re­duce the ab­sorp­tion and de­po­si­tion of LDL and VLDL (bad) serum choles­terol. Oryzanol also helps in re­duc­ing hy­per­ten­sion. It im­proves bone-min­eral den­sity and liver func­tion and gives re­lief from gas­troin­testi­nal dis­tress. Clin­i­cal tri­als con­ducted in Ja­pan have shown that 300 mg per day is the ef­fec­tive dose of oryzanol. Oryzanol was well above the min­i­mum re­quire­ment in all tested brands, rang­ing be­tween 1.25 per cent and 1.81 per cent. Porna had the high­est per­cent­age and Riso the low­est. Saponi­fi­ca­tion value The saponi­fi­ca­tion value helps to de­tect the pres­ence of other oils/fats. Saponi­fi­ca­tion value of rice bran oil should be be­tween 180 and 195.

All brands were within the spec­i­fied limit. Io­dine value The io­dine value is a mea­sure of un­sat­u­rated fats.

All brands were within the spec­i­fied limit. Un­saponifi­able mat­ter Un­saponifi­able mat­ter in­cludes those sub­stances fre­quently found dis­solved in fatty acids and dry­ing oils which can­not be saponi­fied by caus­tic treat­ment,
