Abstract
The present invention relates to a method for utilizing soy molasses as a source for soy sugars which are of high oligosaccharaide content. The invention provides a method for purifying soy molasses comprising the following steps: (i) contacting the soy molasses with alcohol and hydrocarbon solvent mixture, thereby two layers comprising a lower aqueous-alcohol layer and an upper hydrocarbon layer are formed; (ii) collecting the lower aqueous-alcohol layer; (iii) removing coloring, off-flavor and odorous substances; and (iv) removing minerals, thereby a purified soy molasses of more than 90 wt. % sugars, on dry matter basis, is obtained.
Claims15
A process for obtaining soy sugars from soy molasses, the process comprising:
- removing phospholipids;
- removing coloring and odorous organic substances;
- removing minerals to obtain purified soy molasses;
- contacting the purified molasses so obtained with alcohol under high shear mixing
- to obtain a suspension soy sugars particles;
- and
- filtering said suspension,
- thereby a powder containing more than 90 wt. % sugars is obtained.
A process for obtaining powder of soy sugars from soy molasses, the process comprising the following steps:
- a) mixing the molasses with ethanol and hexane;
- b) allowing the mixture of step a to separate into lower alcohol-aqueous phase and an upper hydrocarbon phase;
- c) collecting the lower aqueous phase;
- d) removing coloring, off-flavor and odorous organic substances by anion exchange resins;
- e) removing minerals;
- f) contacting with alcohol under high shear mixing to obtain a suspension of fine purified sugar particles;
- g) filtering said suspension thereby a powder containing more than about 90 wt. %, sugars, on dry matter basis, is obtained.
A purified soy molasses of more than about 90 wt. % sugars, on dry matter basis.
A powder containing more than 90% soy sugars obtained by purifying and solidifying soy molasses.
