Abstract

Pectin, a purified carbohydrate, can be obtained from the dilute acid extract of the inner portion of the rind of CITRUS FRUITS or from apple pomace. This carbohydrate mainly consists of partially methoxylated polygalacturonic acids. Purified pectin should produce not less than 6.7 percent of methoxy group and 74 percent of galacturonic acid on the basis of dried material. In this reaserch, several different methods of isolation of pectin from CITRUS DECUMANA MURRY were compared.Extraction methods are included: extraction by HCL, extraction by EDTA, extraction by water, extraction by amonium oxalate. The methods used for precipitation are included: precipitation by ethanol, precipitation by copper sulfate. The percent of methoxy groups and galacturonic acid have been discussed. Indentification of produced pectin has been on the basis of United States Pharmacopeia. The results of IR spectra of standard and extracted pectin were also compared. The highest percentage of obtained pectin was 17.62% which was extracted by HCl and precipited by ethanol. The percent of methoxy groups was about 6.58 to 7.79 and the percent of galacturonic acid was about 72.99 to 79.98.
