HERRERA-RENGIFO, Jose D.; VILLA-PRIETO, Laura; OLAYA-CABRERA, Anyi C.  e  GARCIA-ALZATE, Luz S.. Starch extraction from cacao shell Theobroma cacao L. as an alternative of bioprospection. Rev. ion [online]. 2020, vol.33, n.2, pp.25-34.  Epub 30-Ago-2020. ISSN 0120-100X.  https://doi.org/10.18273/revion.v33n2-2020002.

The chemical composition of the cocoa husk Theobroma cacao L. allows to catalog it as material of difficult degradation, due its high lignin and cellulose content, where the lignocellulosic material can be used in a wide variety of industrial processes; however, this husk is generally discarded within the crops themselves and this husk generate problems such as the proliferation of pathogenic microorganisms. On the other hand, the starch it’s a granulated substance that it’s presented in different plant matrices, which can be used from the alimentary industry for grant sensorial and organoleptic characteristics, to the manufacture of paper and biodegradable materials. The objective of this research was extracting the starch present in the cocoa husk, thus determinate the possible uses of exploitation of starch, as an alternative of bioprospection. The vegetal material (cocoa husk) was characterized taking into account parameters as pH, moisture percentage, fat and fiber, among others; followed by starch extraction by wet method. The obtained results to the cocoa husk reported a value of pH 5.46 ±0.0057, titratable acidity 0.11±0.038, moisture 84.35±0.017, ash 8.21±0.0057, fat 0.80±0.015, fiber 6.80 ±0.01and the extraction of starch reports 12.04±0.025. To conclude, with the use of the cocoa waste exploitation alternatives can be generate, producing new biomaterials starting of this sub product, being this an alternative of agroindustrial bioprospection.
