Avaliação do método de liquefação enzimática na extração de suco de maçã

Abstract: RESUMOO conceito da tecnologia limpa visa otimizar o processo de extração para obter o máximo de suco da fruta, diminuir perdas e gerenciar a aplicação do resíduo gerado. A utilização de complexos enzimáticos, constituídos por celulases e pectinases, na extração de suco permite, além de modificar características químicas e físico-químicas dos produtos, minimizar a geração de resíduos. O objetivo deste trabalho foi avaliar as condições de extração de suco de maçã por liquefação enzimática e comparar as caracter… Show more

“…A variation of 19.88 % was observed between the TRS values, ranging from 11.61 ±0.48 g/100 mL to 14.49 ±0.44 g/100 mL. This variation was in accordance with the values determined by Oliveira et al (2006) for the application of the same enzymatic preparation in juice: Lightening in the colour of juices, with an increased concentration of enzymes, was observed during both treatments, as pectinases hydrolysis pectic substances from the medium lamella of cell wall and the resulting products may be removed with an impact in the fi nal product characteristics, such as colour (RIBEIRO et al, 2010).…”

“…Analysis of factorial design indicated that the concentration of these enzymes is a more important factor than the temperature, as was observed by Oliveira et al (2006). Figure 3 shows the response surface for the enzymatic preparation and the studied variables.…”

“…No presente estudo, o efeito indesejável desse agente químico pode estar relacionado a comportamentos bioquímicos ainda desconhecidos no yacon (NOGUEIRA et al, 2003;OLIVEIRA et al, 2006). O tratamento 2 (cloreto de cálcio) apresentou um tempo de secagem final menor (14 horas), o que beneficia o aspecto da amostra, deixandoa mais firme (aspecto verificado por meio da sensação tátil) e facilitando o processo de obtenção da farinha.…”
