Содержание зольных веществ в готовом продукте-агаре -составл ет 2,75%, содержание общего азота - 0,03%Агар образует бесцветный прозрачный студень . Предлагаемый способ очистки агаровых растворов по сравнению с известным позвол ет улучшить качество получаемого продукта с образованием прозрачного и бесцветного студн  с малым содержанием зольных веществ и общего азота. Процесс очистки по предлагаемому способу ускор етс . Формула изобретени  1. Способ очистки агаровых растворов от примесей путем расплавлени  и фильтрации. отличающийс  тем, что, с целью улучшени  качества и ускорени  процесса очистки, после расплавлени  раствора в него добавл ют сол ную кислоту дл  снижени  рН среды с последующей выдержкой в кислой среде, а после фильтрации агаровый раствор нейтрализуют раствором едкого натри , при этом расплавление раствора осуществл ют нагреванием его до кипени . (54) METHOD FOR CLEANING AGAR SOLUTIONS FROM IMPURITIES The coagulated precipitate is separated by filtration, the filtrate is neutralized with 2.0 ml of 0.5 N sodium hydroxide solution, raising the pH to 6.5. The ash content in the final agar product is 2.75%, the total nitrogen content is 0.03%. Agar forms a colorless transparent gel. The proposed method for the purification of agar solutions, as compared with the known method, makes it possible to improve the quality of the obtained product with the formation of a transparent and colorless stud with a low content of ash substances and total nitrogen. The cleaning process of the proposed method is accelerated. Claims 1. Method for cleaning agar solutions from impurities by melting and filtration. characterized in that, in order to improve the quality and speed up the purification process, after melting the solution, hydrochloric acid is added to it to lower the pH of the medium, followed by aging in an acidic medium, and after filtration the agar solution is neutralized with sodium hydroxide solution, while melting the solution they are heated by boiling. 2.Способ по п. 1, отличающийс  тем, что кипение агарового раствора ведут в течение от 5 до 10 мин. 2. A method according to claim 1, characterized in that the agar solution is boiled for 5 to 10 minutes. 3.Способ по п. 1, отличающийс  тем, что раствор выдерживают при температуре от 95 до 100°С в течение от 3 до 5 мин. Источники информации, прин тые во внимание при экспертизе 1. Кизеветтер И. В. Переработка морских водорослей и других промысловых водных растений, М., 1967, с. 134.3. A method according to claim 1, characterized in that the solution is maintained at a temperature of from 95 to 100 ° C for 3 to 5 minutes. Sources of information taken into account in the examination 1. Kizevetter I.V. Processing of seaweed and other commercial aquatic plants, M., 1967, p. 134.
