SILVA, Antonio de Pádua Valença da et al. A study of the production of clarified caja fruit juice. Ciênc. Tecnol. Aliment. [online]. 1999, vol.19, n.1, pp.33-36. ISSN 1678-457X. http://dx.doi.org/10.1590/S0101-20611999000100009.
Caja fruits (Spondias lutea L.) from Maranguape plateau, Ceará, Brazil, were processed at a pilot scale level with purpose to obtain clarified juice using pectinolytic enzymes and fining agents. For pulpy juice extraction studies was used at first a pectinolytic enzyme concentration of 120ppm in the pulp and afterwards a concentration of 500ppm in the extracted juice. The "Alcohol proof" was used as a indication of pectin presence. For clarification process of the fruit juice 400ppm of gelatin and 500ppm of silica sol were used as fining agents. The "excess clarification proof" and "insufficient clarification proof" as well as "stability proof" showed negative results, suggesting the efficiency of the clarification process.
