Description

Изобретение относитс  к способу получени  нротамина из молоки осетровых рыб путем обработки измельченного сырь  yKcycHoii кислотой , прессовапи  массы, осаждени  белков и экстракции.This invention relates to a method for producing nrotamine from sturgeon milk by treating powdered yKcycHoii acid with an acid, pressing a mass, precipitating proteins and extracting.

Предлагаемый способ по сравнению с известными удешевл ет получение протамина, уменьшает расход спирта, упрощает и ускор ет процесс производства протамипа за счет освобождени  экстракта от избытков ионов SO|.The proposed method, in comparison with the known methods, makes protamine production cheaper, reduces the consumption of alcohol, and simplifies and speeds up the production of protamight by freeing the extract from excess SO |

Особенность предлагаемого способа заключаетс  в том, что экстракцию измельченного сырь  производ т серной кислотой 3-5%-ной концентрации с последующим отмыванием от ИОНОВ SO.1.The peculiarity of the proposed method is that the extraction of the crushed raw material is carried out with sulfuric acid of 3-5% concentration followed by laundering of ION SO.1.

Способ осуществл ют следующим образом.The method is carried out as follows.

Молоки осетровых рыб измельчаFOT па волчке, добавл ют уксусную кислоту до коагул ции массы, которую отжимают на прессе и дважды обрабатывают гор чим спиртом или ацетоном. Полученную массу промывают жиром, высуизиваюТ при температуре 80°, затем измельчают и просеивают через сито.Sturgeon milt, crushed FOT pas top, add acetic acid to coagulate the mass, which is pressed on the press and twice treated with hot alcohol or acetone. The resulting mass is washed with fat, dried at a temperature of 80 °, then crushed and sieved through a sieve.

Полученный порошок дважды экстрагируют двум  объемами 3-5%-ной (по весу) серной кислоты .The resulting powder is extracted twice with two volumes of 3-5% (by weight) sulfuric acid.

Из экстракта протамин осаждают спиртом, без предварительного разбавлени  экстракта водой, довод  крепость раствора до 70°, затем выделившийс  протамип раствор ют в гор чей воде и снова осаждают спиртом, чем освобождают экстракт от избытков ионов SO4.From the extract, protamine is precipitated with alcohol, without first diluting the extract with water, bringing the strength of the solution to 70 °, then the released protamine is dissolved in hot water and then precipitated with alcohol, thus freeing the extract from excess SO4 ions.

После проведенного двукратного переосаждени  спиртом отдел ют протамин, раствор ют его в гор чей воде, подщелачивают аммиаком дл  отделени  балластных белков и фильтруют раствор в гор чем виде.After a double precipitation with alcohol, the protamine is separated, dissolved in hot water, alkalized with ammonia to separate the ballast proteins, and the solution is filtered in a hot form.

Полученный прозрачный фильтрат разбавл ют спиртом до полного выделени  протамина, отдел ют его от жидкости и сущат спиртом и эфиром .The resulting clear filtrate is diluted with alcohol until protamine is completely isolated, separated from the liquid and dissolved in alcohol and ether.

А 97042- 2 Предмет изобретени отличающийс  тем, что, сA 97042- 2 The subject invention is characterized in that, with
