Изобретение относитс к способам получени пищевого белка из растительного сырь , например из обезжиренного шрота хлопчатника .The invention relates to methods for producing dietary protein from vegetable raw materials, for example, from skimmed cotton meal.
Известен способ получени пищевого белка из шрота хлопчатника, заключающийс в экстракции шрота раствором соли, отделении экстракта и осаждении белка.A known method for producing food protein from cotton meal consists in extracting the meal with a solution of salt, separating the extract, and precipitating the protein.
С целью получени пищевого белка с повышенным содержанием растворимого азота и не содержащего токсичный пигмент госсипол по предлагаемому способу экстракцию хлопкового шрота ведут раствором хлористого аммони при рН преимущественно равном 5-6, а осаждение белка осуществл ют в две стадии: вначале в кислой среде при рН 2-4, а затем - в щелочной среде при рН 7,5-8,5.In order to obtain edible protein with a high content of soluble nitrogen and not containing toxic pigment gossypol according to the proposed method, extraction of cotton meal is carried out with a solution of ammonium chloride at a pH of mainly 5-6, and the precipitation of the protein is carried out in two stages: first, in an acidic medium at pH 2 -4, and then - in an alkaline medium at pH 7.5-8.5.
Пример. 10 кг измельченного заводского шрота экстрагируют 100 л 10% раствора хлористого аммони при рН 5,8-6 в течение 2 час; до конца экстракции рН среды не мен етс . Экстракт от осадка отдел ют вакуумфильтрованием или центрифугированием.Example. 10 kg of crushed mill meal is extracted with 100 liters of 10% ammonium chloride solution at pH 5.8-6 for 2 hours; until the end of extraction, the pH of the medium does not change. The extract from the precipitate is separated by vacuum filtration or centrifugation.
Белок из экстракта осаждают дважды. Первое осаждение производ т добавлением 1 н. HCI до рН: 3. Выпавший белок отдел ютThe protein from the extract is precipitated twice. The first precipitation is made by adding 1 n. HCl to pH: 3. Fallen out protein is separated.
центрифугированием при 1,500 об/мин в течение 5 мин. Полученный белок сушат лиофильно или в распылительной сушилке. Выход белка из этой стадии составл ет до 17%. В сыворотку (экстракт после кислого осаждени ) добавл ют раствор NaOH до рП 8. При этом выпадает нерастворимый в щелочной среде белок. Белок отдел ют центрифугированием и сушат; выход составл ет до 6%. Общий выход белка до 23%. Полученный белок белого цвета с содержанием азота 16%, не содержит токсичных пигментов.by centrifugation at 1,500 rpm for 5 minutes. The resulting protein is dried lyophilically or in a spray dryer. The protein yield from this stage is up to 17%. A solution of NaOH to rP 8 is added to the serum (extract after acid precipitation). At the same time, protein insoluble in alkaline medium precipitates out. The protein is separated by centrifugation and dried; yield is up to 6%. Total protein yield up to 23%. The resulting white protein with a nitrogen content of 16%, does not contain toxic pigments.
Предмет изобретени Subject invention
Способ получени пищевого белка из шрота хлопчатника, заключающийс в экстракции шрота раствором соли, отделении экстракта и осаждении белка, отличающийс тем, что, с целью получени пищевого белка с повышенным содержанием растворимого азота и не содержащего токсичный пигмент, госсипол , экстракцию ведут раствором хлористого аммони при рН преимущественно равном 5-6, а осаждение белка осуществл ют в две стадии: вначале в кислой среде при рН 2-4, а затем - в щелочной среде при рП 7,6-8,5.The method of obtaining dietary protein from cottonseed meal, which consists in extracting the meal with a solution of salt, separating the extract and precipitating the protein, characterized in that, in order to obtain dietary protein with a high content of soluble nitrogen and not containing toxic pigment, gossypol, extraction is carried out with ammonium chloride solution The pH is predominantly 5-6, and the precipitation of the protein is carried out in two stages: first in an acidic medium at pH 2-4, and then in an alkaline medium at a pH of 7.6-8.5.
