Description

Изобретение относитс  к медицине и касаетс  способов получени  препаратов дл  парентерального белкового питани . Известен способ получени  белкового гидролизата из белкового субстрата путем кислотного гидролиза , нейтрализации и осветлени  гидролизата обработкой адсорбентами.The invention relates to medicine and relates to methods for preparing preparations for parenteral protein nutrition. A method of obtaining a protein hydrolyzate from a protein substrate by acid hydrolysis, neutralization and clarification of the hydrolyzate by treatment with adsorbents is known.

С целью улучшени  качества целевого продукта по предлагаемому способу сырье подвергают ферментативному расщеплению, а последуюпдий кислотный гидролиз провод т в атмосфере углекислого газа, обрабатывают Гидроокисью алюмини  и пропускают через колонку с катионитом.In order to improve the quality of the target product according to the proposed method, the raw material is subjected to enzymatic cleavage, and the subsequent acid hydrolysis is carried out in an atmosphere of carbon dioxide, treated with aluminum hydroxide and passed through a column with cation exchange resin.

Пример. 60 л дистиллированной воды помещают в реактор с мешалкой, покрытый кислотоустойчивой эмалью, добавл ют 120 мл концентрированной сол ной кислоты и туда раствор ют 60 г очищенного (не смешанного с сахаром) пепсина активностью 400000- 500000 сывороточных единиц. Температуру раствора пепсина в сол ной кислоте довод т до 37-40°С. В реактор загружают 50 кг подготовленного отмытого и отпрессованного фибрина. Процесс переваривани  длитс  в течение 24 час при посто нном неремешивании с помощью мешалки. При переваривании непрерывно поддерживают посто нство рН 1,5- 2,0 путем добавлени  концентрированной сол ной кислоты (по 200 мл одновременно). Общий расход НС1 1,5-2,0 л на весь ферментативный гидролиз. Ко троль ча рН осуществл ют с помощью рН-метра.Example. 60 liters of distilled water are placed in a stirred reactor coated with acid-resistant enamel, 120 ml of concentrated hydrochloric acid is added and 60 g of purified (not mixed with sugar) pepsin with an activity of 400,000-500,000 whey units are dissolved there. The temperature of the pepsin solution in hydrochloric acid is adjusted to 37-40 ° C. 50 kg of the prepared washed and pressed fibrin is loaded into the reactor. The digestion process lasts for 24 hours with constant unmixing with an agitator. During the digestion, the pH constant is kept between 1.5 and 2.0 by adding concentrated hydrochloric acid (200 ml at a time). The total consumption of HC1 1.5-2.0 liters for the entire enzymatic hydrolysis. The pH co is performed using a pH meter.

После окончани  ферментативного гидролиза дл  удалени  непереварившихс  частиц раствор фильтруют через четырехслойную марлю в закрытой системе. Профильтрованный нептолизат снова загружают в реактор и добавл ют 5 кг (2720 мл) химически чистойAfter the end of enzymatic hydrolysis to remove non-digestible particles, the solution is filtered through four-layer gauze in a closed system. The filtered neptolysate is again charged to the reactor and 5 kg (2720 ml) of chemically pure is added.

концентрированной серной кислоты (уделып н вес 1,84). Через подготовлеппый раствор, содержащий 5% серной кислоты, перед началом нагревани  пропускают в течение 30 мин углекислый газ. Зате.м включают подогрев, довод т температуру до 100°С и, посто ппо пропуска  углекислый газ в течение всего процесса гидролиза, провод т кислотный гидро.;1из в течение 7 час при 100°С. Затем гидролизат охлаждают и фильтруют через бумажныйconcentrated sulfuric acid (weight of 1.84). Carbon dioxide is passed through a prepared solution containing 5% sulfuric acid before starting to heat. Then they include heating, bring the temperature to 100 ° C and, constantly passing carbon dioxide during the entire hydrolysis process, conduct acidic hydro. 1 for 7 hours at 100 ° C. The hydrolyzate is then cooled and filtered through paper.

фильтр. Готовый кислотный гидролизат затем подвергают дальнейшей обработке. Апиопит ЭДЭ-Ю-П, просе ппый через сито N° 4, замачивают на 24 час в 25%-но.м растворе хлористого натри , после чего смолу дистиллированной водой до полного удалени  соли (проба на AgMOa). Затем смолу заливают одпонормальным раствором НС1 па 6 час, после чего смолу отмывают от ионов хлора дистиллированпой водой. Подготовленную смолу загружают в колонку и проп скаютfilter. The finished acid hydrolyzate is then further processed. Apiopite EDE-U-P, millet through a No. 4 sieve, is soaked for 24 hours in a 25% solution of sodium chloride, after which the resin is distilled with water until salt is completely removed (sample AgMOa). Then, the resin is poured with an odd-normal HC1 solution for 6 hours, after which the resin is washed from chlorine ions with distilled water. The prepared resin is loaded into the column and prop out.
