Abstract

Brazil is a great producer of fruits and vegetables, but post-harvest losses still are considerable. The application of protective coatings on fruits is an alternative technology of low cost and easy use, attributing barrier to the loss of humidity, gases and antimicrobial action. Carnauba wax is extensively used in the food and coating industry, however few studies exist with nanostructured coatings of that material. In previous study (master degree of the candidate) was possible the synthesis and characterization of carnauba wax nanoemulsion, observing potential use on fruits coating due to the properties of barrier to moisture; intense brightness and compliance with the brasilian´s resolution -RDC ANVISA nº 8 / 2013. That resolution provides on the food additives allowed on the surface treatment of fresh fruits. Hydroxypropyl methylcellulose (HPMC) is a hydrophilic polysaccharide from cellulose and it used for coatings due to its filmogenic characteristic, moisture keeping and oxygen barrier. Studies indicate the use of extracts of ginger rhizome (Zingiber officinale) to reduction microorganisms in food, with potential use that as an active agent in inert coatings. Thus, join characteristics and properties of these materials can increased coating action, improving physical, chemical, mechanical and antimicrobial properties. The aim of that work is to evaluate the activity of extracts obtained from ginger rhizome to antimicrobial application and adding them in the development of edible coatings to postharvest quality. Papaya fruit was choose as a model fruit, due to its economic importance for the internal and external market, and because it is climacteric fruit, subject to physiological changes and diseases during post-harvest storage. Therefore that proposal expected to reduce qualitative and quantitative losses during fruit post-harvest storage and improve marketing system. (AU)
