435 95

Abstract:

The invention relates to the preparation of a high maltose syrup containing from 60 to 80% maltose, from 12 to 24% glucose and from 8 to 16% sugars having a DP of three or more by the enzymatic saccharification of partially hydrolyzed starch having a dextrose equivalence of from 1 to about 30; the high maltose syrups obtained from such process; the hydrogenation of such high maltose syrup to form maltitol blends containing from 60 to 80% maltitol and from 12 to 24% sorbitol; and the so prepared maltitol blends, such blends having a desired combination of high sweetness and humectancy.

Abstract:

A method for producing 1-hydroxyethyl-2-undecyl-2-imidazoline is disclosed. Lauric acid is reacted with a molar excess of aminoethylethanolamine (AEEA) under vacuum. A first column containing vapor-liquid contact means is used to rectify the reactor overhead vapor (water of reaction plus AEEA); the overhead (water) is discarded; and the bottoms (primarily AEEA) returned directly to the reactor. After substantially all the water has been removed, the reactor overhead is fed to a second column, which is devoid of vapor-liquid contact means, whereby unreacted AEEA is removed. A high purity product remains in the reactor. Other carboxylic acids, such as, fatty acids, may be used in place of lauric acid, and other diamines, such as, ethylenediamine and diethylenetriamine, may be used in place of AEEA, to produce the analogous imidazolines.
