Description
Изобретение отиоситс -к технологии производства нищевых кислот, например к производству молочной и лимонной кислот.The invention of Otoshits is a technology for the production of lean acids, for example, for the production of lactic and citric acids.
Известны различные способы выделени пищевых кислот. Наиболее распространенным вл етс способ получени кислот путем осаждени их из сброженных -растворов в виде солей кальци , расщеплени лоследних серной кислотой с последующим осветлением получевного раствора.Various methods for the isolation of food acids are known. The most common is the method of producing acids by precipitating them from fermented β-solutions in the form of calcium salts, splitting the latter with sulfuric acid, followed by clarification of the resulting solution.
Однако при известных способах растворы кислот от крас щих веществ очищаютс недостаточно качественно.However, with the known methods, the acid solutions of the dyestuffs are not sufficiently cleaned.
Дл повыщени качества кислоты предлагаетс процессы расщеплени и осветлени осуществл ть одновременно. В качестве осветл ющего агента используют кислый коллактивит , полученный, лапример, лутем смещени нагретой серной кислоты с древесными опиЛками.To increase the quality of the acid, it is proposed to carry out the processes of cleavage and clarification at the same time. An acidic collativitis obtained, for example, by displacing heated sulfuric acid with wood species is used as a clarifying agent.
Пример. По известному способу расщепление , лапример, лактата кальци проводитс следующим образом. К 200 г 16,3%-iHoro раствора лактата добавл ют 14,56 г серной кислоты в расчете на моногидрат, исход из стехиометрии .реакции разложени . Разложение ведут в течение 2 час при 55-60°С. После расщеплени к раствору молочной кислоты прибавл ют от 0,5 до 4% активированного угл (к весу 40%-ной кислоты) и выдерн ивают при 55°С в течение 30 мин дл осветлени .Example. In a known manner, the digestion of, for example, calcium lactate is carried out as follows. To 200 g of a 16.3% -iHoro lactate solution was added 14.56 g of sulfuric acid based on the monohydrate, based on the stoichiometry of the decomposition reaction. The decomposition is carried out for 2 hours at 55-60 ° C. After cleavage, 0.5 to 4% activated carbon (by weight of 40% acid) is added to the solution of lactic acid and removed at 55 ° C for 30 minutes to clarify.
По предлагаемому способу расщепление и осветление совмещают. К 200 г 16,3%-ного раствора лактата кальци добавл ют 23,10 г коллактивита при содержании в нем 63% моногидрата серной КИСЛОТЫ . Коллактивит добавл ют при перемещивании в течение 2 час при 55° С и выдерживают 30 мин.According to the proposed method, the splitting and clarification combine. To 200 g of a 16.3% calcium lactate solution was added 23.10 g of collativitis with a content of 63% sulfuric acid monohydrate. Collativitis is added while moving for 2 hours at 55 ° C and held for 30 minutes.
В результате по предложенному способу получаетс кислота, цветность которой в 2,5 раза ниже, чем кислоты, полученной известным способом.As a result, according to the proposed method, an acid is obtained, the chromaticity of which is 2.5 times lower than the acid obtained by a known method.
Предмет изобретени Subject invention
Способ выделени пищевых кислот из сброженных растворов, например молочной, путем осаждени их в виде солей кальци , расщеплени последних серной кислотой и осветлени полученного раствора, отличающийс тем, что, с целью повыщени качества кислоты, процессы расщеплени и осветлени осуществл ют одновременно, причем серную кислоту перед введением в раствор нагревают и смешивают с древесными опилками и полученный при этом кислый коллактивит используют в качестве осветл ющего агента.A method of separating food acids from fermented solutions, such as lactic, by precipitating them in the form of calcium salts, splitting the latter with sulfuric acid and clarifying the resulting solution, characterized in that, to increase the quality of the acid, the processes of cleavage and clarification are carried out simultaneously, and sulfuric acid Before being introduced into the solution, it is heated and mixed with sawdust, and the acidic collapse of acid thus obtained is used as a clarifying agent.
