Изобретенне относнтс к снособу полученн пентозанов, используемых в хлебопеченнн в качестве гелеобразующего средства, и, в частности, дл получени линейных цепочек Д-ксилониранозов, соединенных в р-1-4, с боковой нитью С-Сз и/нли Сз едииицами L-арабо-фуранозы, имеющими боковые цепочки с Сз и/илн Cs.The invented relation to the cut is obtained pentosans used in bread baking as a gelling agent, and, in particular, to obtain linear chains of D-xylonyranoses, connected in p-1-4, with the side thread C-C3 and / nly Cz with L-arabi lines - furanoses having side chains with Cs and / or Cs.
Известен способ нолучени пентозанов, предусматривающий экстрагирование исходного сырь органическим растворителем, обработку экстракта щелочным раствором и извлечение пентозанов ;.A known method of obtaining pentosans, which involves extracting the feedstock with an organic solvent, treating the extract with an alkaline solution, and removing the pentosans;.
Однако такой способ не нозвол ет получать пентозаны, используемые в хлебопечении .However, this method does not allow to obtain pentosans used in baking.
Целью изобретени вл етс возможность получени пентозанов, используемых в хлебопечении , и улучщение качества хлеба.The aim of the invention is the possibility of obtaining pentosans used in baking, and improving the quality of bread.
Дл этого в качестве исходного сырь используют злаковые растени , при этом экстракцию провод т при рН среды 8-13 и температуре 53-56°С, а извлечение пентозанов осуществл ют электродиализом.For this purpose, cereals are used as a raw material, the extraction is carried out at a pH of 8-13 and at a temperature of 53-56 ° C, and the extraction of pentosans is carried out by electrodialysis.
Сущность способа но сн етс примерами его вынолнени .The essence of the method is illustrated by examples of its implementation.
Пример 1. Исходный материал, в качестве которого использованы злаковые растени (их зерна, стебли, листь или корни), подвергают первой экстракции растворомExample 1. The starting material, in which cereals were used (their grains, stems, leaves, or roots), is subjected to a first extraction with a solution

2%-ного формальдегида в течение 8 ч при температуре 50°С с целью дезактнвации ферментов в нсходиом материале и экстракции нз него водорастворимых компонентов. Осадок обрабатывают 10 н. раствором NaOH при температуре окружающей среды и выдерживают в течение 12 ч, при этом производ т строгий контроль рН массы дл поддержани его в предельных значени х,2% formaldehyde for 8 hours at 50 ° C in order to deactivate the enzymes in the descaled material and extract water-soluble components from it. The precipitate is treated with 10 n. NaOH solution at ambient temperature and incubated for 12 hours, while producing strict control of the pH of the mass to maintain it in the limit values
приблизительно от 11 до 12,5, после истечени этого времени экстракт удал ют.from about 11 to 12.5, after this time has elapsed, the extract is removed.
Затем погружают осадок в 10 н. NaOH нагревают до температуры 53°С и провод т экстракцию в течение 48 ч. ЭкстракциюThen the sediment is immersed in 10 n. The NaOH is heated to 53 ° C and extraction is carried out for 48 hours. Extraction
провод т в несколько этапов, использу NaOH убывающей концентрации, до истощени исходного материала. Во врем экстракции рН должен ноддерживатьс между 8 н 13, предпочтнтельио между 11 и 12,5,carried out in several steps using decreasing concentration of NaOH until the source material is depleted. During extraction, the pH should be between 8 and 13, preferably between 11 and 12.5,
экстракцию провод т в инертной атмосфере в присутствии азота. Экстракт декантируют и разбавл ют, если его в зкость слищком высока. Затем из экстракта удал ют нерастворимый крахмал посредством центрифугировани .the extraction is carried out in an inert atmosphere in the presence of nitrogen. The extract is decanted and diluted if its viscosity is too high. The insoluble starch is then removed from the extract by centrifugation.
Дл удалени щелочи раствор иодвергают электродиализу, причем рН материала нри этом поддерживают на ровне 5. Затем полученный продукт высущивают,To remove the alkali, the solution is subjected to electrodialysis, and the pH of the material is kept at an equal level of 5. Then the resulting product is dried,
