Preparation of Alkyl Esters of Pectin and Pectic Acid

Alkyl esters of pectin and pectic acid have been prepared via three different synthetic routes. Enhancements of intrinsic viscosity, binding to bile acids and to isolated soy protein were shown for these novel pectin derivatives. The development of new and improved pectin-containing products may be enhanced by the ease of preparation and improved functionality of such compounds.

Preparation of fatty acid methyl esters for gas-liquid chromatography.

A convenient method using commercial aqueous concentrated HCl (conc. HCl; 35%, w/w) as an acid catalyst was developed for preparation of fatty acid methyl esters (FAMEs) from sterol esters, triacylglycerols, phospholipids, and FFAs for gas-liquid chromatography (GC). An 8% (w/v) solution of HCl in methanol/water (85:15, v/v) was prepared by diluting 9.7 ml of conc. HCl with 41.5 ml of methanol....

THE PREPARATION OF cl-GALACTURONIC ACID FROM LEMON PECTIC ACID.*

A noteworthy advance in the knowledge of the constitution of the pectic compounds was afforded through the excellent researches of Ehrlich and his coworkers (1)) who discovered that d-galacturonic acid, an isomer of d-glucuronic acid, was a constituent of all pectic substances so far examined. Later researches showed that the pectic acid obtainable from sugar beet pectin (2) can be regarded as ...
