Abstract
Disclosed is a process for obtaining glycan extracts from apple pomace in which a mixture comprising apple pomace and water is extracted into water so that an aqueous glycan extract is obtained; at least one alcohol is added to the extract, whereby a solid glycan extract is precipitated; and the solid glycan extract is separated from the liquid. Also disclosed is a process for producing functionalized glycan wherein the glycan is converted using at least one amine into at least one functionalized glycan. Also disclosed are a functionalized glycan that is produced by the method and uses thereof.
Claims7
A process for producing functionalized glycan comprising the process comprising:
- (a) providing a mixture comprising apple pomace and water;
- (b) subjecting the mixture to an extraction treatment in which at least one glycan is extracted from the apple pomace into the water so that an aqueous glycan extract is obtained and comprises the at least one glycan;
- (c) adding at least one alcohol to the aqueous glycan extract, whereby a solid glycan extract is precipitated and comprises the at least one glycan;
- and
- (d) separating the solid glycan extract from remaining liquid component (i) and obtaining a solid glycan extract from apple pomace that contains at least one glycan and converting the at least one glycan into at least one functionalized glycan by reacting with at least one amine selected from the group consisting of 2-chloro-N,N-diethylethylamine, 2-chloro-N,N-dimethylethylamine, 3-dimethylamino-1-propyl chloride, 1-(2-chloroethyl)-pyrrolidine, 1-(2-chloroethyl)piperidine, 1-(3-chloropropyl)piperidine, (2-chloroethyl)trimethylammonium chloride, and (3-chloro-2-hydroxypropyl)trimethylammonium chloride.
A functionalized glycan produced by a process comprising:
- (a) providing a mixture comprising apple pomace and water,
- (b) subjecting the mixture to an extraction treatment in which at least one glycan is extracted from the apple pomace into the water so that an aqueous glycan extract is obtained and comprises the at least one glycan,
- (c) adding at least one alcohol to the aqueous glycan extract, whereby a solid glycan extract is precipitated and comprises the at least one glycan, and
- (d) separating the solid glycan extract from remaining liquid component, and
- (e) reacting the solid glycan extract with at least one amine to produce the functionalized glycan, wherein the at least one amine is selected from the group consisting of 2-chloro-N,N-diethylethylamine, 2-chloro-N,N-dimethylethylamine, 3-dimethylamino-1-propyl chloride, 1-(2-chloroethyl)-pyrrolidine, 1-(2-chloroethyl)piperidine, 1-(3-chloropropyl)piperidine, (2-chloroethyl)trimethylammonium chloride, and (3-chloro-2-hydroxypropyl)trimethylammonium chloride.
