Abstract
"PROCESSO DE OBTENçãO DE FRUTOSE PURA E XAROPE INVERTIDO A PARTIR DE SACAROSE". é um processo de conversão da sacarose por via enzimática em glicose e flutose. O biocatalisador utilizado é a inulinase de Kluyveromyces marxianus imobilizada em gel alginato de cálcio. A enzima é obtida por fermentação em meio sintético e a seguir purificada parcialmente por precipitação com etanol. O passo seguinte é a imobilização da inulinase em suporte sólido para facilitar a separação dos produtos da reação enzimática. A montagem do biorreator é feita montando uma coluna de leito fixo com as esferas de inulinase imobilizada e as condições de operação foram otimizadas para conversão da sacarose em frutose e glicose. As condições de operação determinam a composição final do produto, que pode conter somente glicose e frutose ou uma mistura de glicose e frutose e sacarose não convertida. Este produto final obtido, o xarope de açúcar invertido, é muito utilizado na produção de refrigerantes, doces e produtos farmacêuticos. Para obtenção da frutose pura é necessária uma etapa final de separação que é realizada em coluna de leito fixo contendo zeólita Y na forma bárica. A eluição é feita com solução etanólica a 15%, produzindo mais de 65% da frutose na forma pura. A frutose é apontada como o açúcar ideal do ponto de vista nutricional, já que devido ao seu elevado poder edulcorante acarreta uma redução calórica na dieta e pode ser utilizada por pessoas diabéticas e obesas. O microrganismo do gênero Kluyveromyces possui identificação GRAS do FDA americano não apresentando, portanto risco para utilização em alimentos de consumo humano."Process for obtaining pure fructose and inverted syrup from sucrose". It is a process of enzymatic conversion of sucrose into glucose and flutose. The biocatalyst used is Kluyveromyces marxianus inulinase immobilized on calcium alginate gel. The enzyme is obtained by fermentation in synthetic medium and then partially purified by ethanol precipitation. The next step is the immobilization of the inulinase on solid support to facilitate separation of the enzyme reaction products. Bioreactor assembly is done by mounting a fixed bed column with immobilized inulinase beads and operating conditions have been optimized for conversion of sucrose to fructose and glucose. Operating conditions determine the final product composition, which may contain only glucose and fructose or a mixture of unconverted glucose and fructose and sucrose. This final product obtained, invert sugar syrup, is widely used in the production of soft drinks, sweets and pharmaceuticals. In order to obtain pure fructose, a final separation step is required, which is performed in a fixed bed column containing zeolite Y in baric form. Elution is with 15% ethanolic solution, producing over 65% of fructose in pure form. Fructose is indicated as the ideal sugar from the nutritional point of view, because due to its high sweetening power causes a caloric reduction in the diet and can be used by diabetic and obese people. The microorganism of the genus Kluyveromyces has US FDA GRAS identification and therefore does not present a risk for use in food for human consumption.
