Resumo: Pitaya is a fruit of epiphyte cacti of the genus Hylocereus, and can be found more easily in Brazilian territory in two different species: White Pitaya (Hylocereus undatus) red bark and white pulp and Red Pitaya (Hylocerus Polyrhizus) and red pulp. The objective of the work was to make polymeric films with the addition of red pitaya pulp in order to detect possible properties of the pulp, that when inserted in the films, give it relevant characteristics for future active packaging. Three different formulations were made: the first formulation containing only 2% chitosan (by weight); the second formulation containing 2% chitosan plus 1mL of pulp; the third formulation containing 2% chitosan, plus 5mL of pulp. In order to characterize the three film formulations, the following analyzes were performed: Thickness, Water Vapor Permeability (PVA), moisture content and water solubility. At the end, it was observed that the addition of different concentrations of pulp changed the characteristics of biopolymer films.

A Pitaya é um fruto de cactos epífitos do gênero Hylocereus, podendo ser encontradas mais facilmente em território brasileiro em duas diferentes espécies: Pitaya Branca (Hylocereus undatus) casca vermelha e polpa branca e a pitaya vermelha (Hylocerus Polyrhizus) e polpa vermelha. O objetivo do trabalho foi confeccionar filmes poliméricos com adição de polpa de pitaya vermelha afim de detectar possíveis propriedades da polpa que ao serem inseridas nos filmes, dê ao mesmo características relevantes para futuras confecções de embalagens ativas. Foram confeccionadas três formulações distintas: a primeira formulação contendo somente quitosana 2% (em massa); a segunda formulação contendo quitosana 2% acrescido de 1mL de polpa; a terceira formulação contendo quitosana 2%, acrescida de 5mL de polpa. Afim de realizar a caracterização das três formulações de filmes, foram realizadas as seguintes análises: Espessura, Permeabilidade ao Vapor D’água (PVA), teor de umidade e solubilidade em água. Ao final, observou-se que a adição de diferentes concentrações de polpa alterou as características dos filmes biopoliméricos.Universidade Federal de Viçosa - UFV2020-10-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1065910.18540/jcecvl6iss4pp0480-0485The Journal of Engineering and Exact Sciences; Vol. 6 No. 4 (2020); 0480-0485The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 4 (2020); 0480-0485The Journal of Engineering and Exact Sciences; v. 6 n. 4 (2020); 0480-04852527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/10659/6056Copyright (c) 2020 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKoury Abreu, JúlliaReis, Arlete Barbosa2021-02-23T20:11:08Zoai:ojs.periodicos.ufv.br:article/10659Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2021-02-23T20:11:08Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
