COSTA, Marta Cristina et al. Preservation of cupuaçu pulp [Theobroma grandiflorum (Willd. Ex Spreng.)Schum] by combined methods. Rev. Bras. Frutic. [online]. 2003, vol.25, n.2, pp. 213-215. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452003000200007.

This work had the objetive of evaluate chemical and physico-chemical standards as a support in the development of the preservation process of cupuaçu pulp by combined methods as an alternative to costly technics (ex.: freezing), reducing post-harvests lost of cupuaçu pulp for small and medium farmers. The following obstacles were chosen: water activity adjustment for values of Aw 0,97 and Aw 0,95 by addition of sucrose (22,5% and 34%, respectively); slow reduction of pH to 3,0; addition of sodium benzoate (500ppm); addition of sulfite dioxide (400ppm) and the use of branching (T = 90ºC/2min). The results indicated that the selected obstacles were suitable to guarantee the microbiological and physico-chemical stability of the pulp during 20 days of storage.
