When I visited one of the NTUC stores to at look at what rice bran oil they carried, I only saw large bottles of the NTUC house branded rice brand oils. They also had some other brands which were a mixture of several oils mixed together. Obviously these products were inferior products being sold based on price. There was no indication or mention of oryzanol content.
I didn't even know what Oryzanol is & had to google it.
With this knowlege people can identify what to look for.
