摘要:
The invention provides processes for the extraction of sugar from sugar-bearing plant material such as sugar cane. Accordingly, in one aspect of the invention, a process for extracting sugar from sugar-bearing plant material comprises contacting the sugar-bearing plant material with an extractant solution comprising water and a surfactant; and separating the extractant solution from the sugar-bearing plant material. One example of a suitable surfactant is a poly(alkylene oxide) polymer such as a poly(propylene oxide) polymer, a poly(ethylene oxide) polymer, or a poly(propylene oxide)/(ethylene oxide) copolymer.

Beet juice is purified, then concentrated and treated in several steps for boiling and centrifugal separation to effect recovery of sucrose therefrom. The molasses remaining after the separation of sucrose from massecuite is treated with .alpha.-galactosidase to effect hydrolysis of raffinose present in the molasses. The resultant raffinose hydrolyzate is introduced into a calcium saccharate-forming step, wherein quicklime is continuously added to the hydrolyzate to form saccharate within the hydrolyzate. From the calcium saccharate-forming step, nearly the same volume of the saccharate-containing solution as that of the raffinose hydrolyzate fed therein is forwarded to a filtering and washing step. The resultant saccharate cake is sent back to the step for purification. From said calcium saccharate-forming step, the same saccharate-containing solution is also withdrawn in a volume of from three to ten times that of said raffinose hydrolyzate fed therein, is cooled and thereafter returned to the calcium saccharate-forming step. The saccharate-containing solution is circulated several times through this step so that discharge of waste molasses is eliminated and the sucrose contained in the beet juice is efficiently recovered substantially in its entire amount.

The invention relates to a method the preparation of an inverted sugar product, called high test molasses, using novel reaction parameters. More particularly it relates to the preparation of high-test molasses using an acid wherein the loss of sugar due to use of acid and high temperature as in conventional method is eliminated.

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.
