Description

Изобретение относитс  к способам получени  пектовой кислоты и может быть иснользовапо дл  получени  желе с низким содержанием сахара.The invention relates to methods for producing pectic acid and can be used to make low sugar jelly.

Известны способы получени  пектовой кислоты путем обработки пектина щелочью, выдержки полученной смеси, введени  сол ной кислоты, смешивани  полученного осадка с растворителем, фильтрации и последующей сушки.Methods are known for producing pectic acid by treating pectin with an alkali, soaking the mixture obtained, introducing hydrochloric acid, mixing the obtained precipitate with a solvent, filtering and then drying.

Однако вы.код кислоты, нолучеппой по этим способам, педостаточен, а расход растворител  значителен. С целью повышени  выхода кислоты н сокращени  расхода растворител  по предлагаемому способу перед фильтрацией производ т удаление ионов металла н хлора обработкой раствора катиопитом КУ-2 и анионитом АВ-17 с носледующнм добавлением ацетона дл  нолного осаждени  кислоты, причем в качестве .растворител  иснользуют смесь ацетона с водой.However, the acid code, but using these methods, is sufficient, and solvent consumption is significant. In order to increase the yield of the acid and reduce the consumption of the solvent by the proposed method, prior to filtration, metal ions and chlorine ions are removed by treating the solution with cationic resin KU-2 and anion exchanger AB-17 with the following addition of acetone for precipitation of the acid, and using acetone with solvent water

Пример. Раствор ют 5 г пектина в 100 мл воды. Дл  омылени  метоксильных групн пектина к раствору добавл ют 25 мл 1 н. раствора едкого натра. Смесь выдерживают в течение 30 мин при комнатной темнературе.Example. Dissolve 5 g of pectin in 100 ml of water. To saponify the methoxyl pectin groups, 25 ml of 1N is added to the solution. caustic soda solution. The mixture is incubated for 30 min at room temperature.

The yield is 3.85 g or 77%. Thus, the total consumption of organic solvents is reduced by 30-40 times.

Они ноказывают наличие 1-галактуроновой кнслоты и следов рамнозы н арабннозы.Chromatograms of nitric acid hydrolyzes of nektic acid, obtained according to the classical and proposed methods, are identical. They indicate the presence of a 1-galacturonic nodule and traces of rhamnose and arabnnosa.

Дл  иолученн  1 г пектовой кислоты по предлагаемому способу требуетс  45 мл ацетона .For 1 g of pectic acid by the proposed method, 45 ml of acetone is required.
