Abstract: The present invention relates to a process for preparing isoflavone aglucone using Rhodotorula glutinis, more specifically, to a novel Rhodotorula glutinis strain (KCCM-10172) which can be isolated from fermented soybeans and has a good ability to convert into isolfavone aglucone, and a process for preparing isoflavone aglucone using the said strain which comprises culture for 30-54 hours in a condition of pH 4.0-8.0 and 25-35° C. using an extract from soybeans or germs of soybeans as a medium and control of content of dissolved oxygen to produce isoflavone containing aglucone of a purity of 90% or more.

Abstract: A mechanical separation method for isolating soybean embryo in high purity or concentration from a soybean/embryo mixture produced by a conventional split/crush process and containing less than 2% by weight of embryos. The method comprises passing the mixture through a peeling process to separate it into a combination of split soybeans and a mixture of hulls and embryos containing about 20% by weight of embryos. The mixture is sifted to isolate a mixture of hulls and 30-70% by weight of embryos. Finally the mixture of hulls and embryos is separated by gravity force, such as in a cyclone device, to produce a hull/embryo mixture containing 90-97% by weight of embryos.

Abstract: A process for obtaining, by separation, highly pure, water soluble polydextrose using a continuous simulated moving bed system. The process involves separation from a crude polydextrose mixture containing 75-95 wt % polyglucose, 2-10 wt % glucose, 1-5 wt % anhydroglucose, 1-5 wt % sorbitol and 0.5-3 wt % citric acid. The highly pure, i.e., over 99.2%, water soluble polydextrose obtained by this process can be used as a low calorie sweetener in diet foods and drinks and does not have a bitter after taste.
