Extração e Caracterização de Uma Enzima Proteolítica do Curauá (Ananas erectifolius)

Ananas erectifolius (curaua) is a fibrous vegetable that can be found in North and Central West regions of Brazil. It is a bromeliaceae family plant which physico-chemical features provides great potential in the automobilistic industry as a source of fibers. As commonly described in other bromeliaceae species, it contains significant levels of bromelain, of high commercial value and wide range of aplications in food, pharmaceutical and cosmetic industry. In this paper, experimental tests were performed to evaluate the extraction of the proteolytic enzymes of the Ananas erectifolius under different pH and temperature conditions to determine in which ones the enzymatic activity would be the maximum for later purification of the bromelain. The two commercially available curaua varieties (white and purple) were used in the experiments and the results showed the same optimal pH of 8,5 for both varieties and different temperatures of 30ºC for the white one, and 10ºC, 20ºC and 35ºC for the purple one.
