Influência da embalagem na qualidade de armazenamento de café verde

Abstract

The unripe coffee bean needs good storage to maintain its characteristics for commercialization. The traditional packaging for this purpose is usually jute. However, in order to improve the performance of the raw material and ensure good quality, several packages have been developed to meet this demand, such as Oxi Free commercial packages (high barrier to oxygen, easy sealing, high barrier to humidity, high tear strength and solvent-free UV technology). In view of the above, this Course Completion Work will aim to evaluate the performance of three different commercial packages, with high oxygen barrier, available for packaging green coffee for export, during storage for 6 months. To this end, green coffee will be stored in packaging and evaluated in relation to the characteristics of the grain (moisture, sorption isotherm, color and instrumental texture and density), and the characteristics of the packaging (tensile strength and permeability to water vapor). during the periods of: 0, 3 and 6 months, respectively. It is expected to obtain data that prove that producers' investment in highbarrier packaging can provide stability and greater quality to unripe coffee bean.
