The objective of this work was to seek an optimized coating capable of prolonging the shelf life of papaya that is affected by post-harvest diseases caused by Collectotrichum gloeosporioides and Fusarium spp. The coatings / films can be obtained from gelatine from fishing industry’s co-products, such as Nile’s tilapia’s (Oreochromis niloticus) skin of the whose processing results in more than half of the animals' weight as co-products. For the conversion of hides into gelatins, it was required to perform permutations between three reagents in the following recommendations: butanol 15%, hydrochloric acid 0.8% and acetic acid 0.8%. Analyzes of the different solutions were carried out in order to obtain the optimized base, that is, with high gel strength and low lipid concentration. The gelatin chosen for making the film was a number 9 made with 25% butanol and 37.5% acetic acid (0.8%) and hydrochloric acid (0.8%) which contained a content of 7.76% humidity, 1.42% ash, 84.93% protein, 0.43% lipids, 2.94 pH and 872.20 bloom of gel strength, generating a yield of approximately 13%. After preparing the film with this optimized gelatin and surfactants (Tween 80 and sodium dodecyl sulfate (SDS)), the mechanical and barrier properties were investigated. Tensile strength, Young's modulus and elongation values were found from 3.49 to 38.78 MPa; 1.97 to 14.16 MPa; and 16.40 to 120.49%, respectively. As for the water vapor permeability barrier property, a low value range of 5.90 to 10.12 g.mm.h-1.m2.kPa-1 was found. The thickness varied according to the addition of surfactant, ranging from 0.10 to 0.25 mm. The treatment with the lowest concentration of surfactant (40%) was the most efficient, as it had the best barrier properties and was the least thick, which classifies it as a good option for coating food. This film was then applied to systems with different relative humidity in order to obtain an adsorption isotherm and the Kühn model allowed the best adjustment to the experimental data, considering all the statistical parameters and the random (randomized) distribution of the residues simultaneously. The effect of the application of this film was investigated, through physical-chemical analyzes during the ripening, when different concentrations of pitomba’s extract were used. It was found that the parameters L, C and h are capable of expressing color changes during ripening in both the skin and the pulp. The content of total soluble solids is closely related to the ripening of the fruit and was found in the range of 8.77 to 11.95º Brix where only one formulation wasn’t able to meet the minimum amount of ºBrix of ripe papayas, suitable for export. The lycopene content was 12.28 to 25.79 μg lycopene / g of papaya for the analyzes on the final day. The loss of mass in all cases was less than 10%, but the most significant losses were related to the presence of post-harvest diseases. As a conclusion, it was observed that concentrations of pitomba extract from 10% would be able to reduce the post-harvest diseases present and delay the ripening of the papaya, being attractive to the foreign market. A indústria de alimentos sofre elevadas perdas com a frutas e hortaliças ao longo de toda cadeia produtiva, como por exemplo o mamão, uma fruta de exportação com clima propício para seu desenvolvimento no Brasil. Tais perdas instigam a busca por alternativas como o desenvolvimento de filmes para revestir alimentos e prolongar sua vida de prateleira. O objetivo deste trabalho foi buscar um revestimento otimizado capaz de prolongar a vida de prateleira do mamão que é afetado por doenças pós-colheita causadas pelo Collectotrichum gloeosporioides e Fusarium spp. Os revestimentos/filmes podem ser produzidos a partir de gelatina de coprodutos da indústria pesqueira, como a pele da tilápia do Nilo (Oreochromis niloticus) cujo processamento resulta em mais da metade do peso dos animais como coprodutos. Para a conversão das peles em gelatinas requereu-se a realização de permutações entre três reagentes nas seguintes concentrações: butanol 15%, ácido clorídrico 0,8% e ácido acético 0,8%. Foram feitas análises nesses diferentes tratamentos, a fim de se obter a formulação otimizada, ou seja, com elevada força de gel e baixa concentração lipídica. A gelatina escolhida para elaboração do filme foi a de número 9 elaborada com 25% de butanol e 37,5% de ácido acético (0,8%) e clorídrico (0,8%) a qual continha um teor de 7,76% de umidade, 1,42% de cinzas, 84,93% de proteínas, 0,43% lipídeos, 2,94 de pH e 872,20 bloom de força de gel, gerando um rendimento de aproximadamente 13%. Após a elaboração do filme com essa gelatina otimizada e surfactantes (Tween 80 e o dodecil sulfato de sódio (SDS)), investigou-se as propriedades mecânicas e de barreira. Encontrou-se valores de resistência à tração, módulo de Young e elongação de 3,49 a 38,78 MPa; 1,97 a 14,16 MPa; e 16,40 a 120,49%, respectivamente. Quanto à propriedade de barreira de permeabilidade a vapor de água encontrou-se faixa de baixo valor de 5,90 a 10,12 g.mm.h-1.m2.kPa-1. A espessura variou conforme a adição de surfactante, sendo de 0,10 a 0,25 mm. O tratamento com a menor concentração de surfactante (40%) foi o mais eficiente, pois apresentou as melhores propriedades de barreira e foi o menos espesso, o que o classifica como sendo uma boa opção para revestimento de alimentos. Foi então aplicado esse filme em sistemas com diferentes umidades relativas a fim de se obter uma isoterma de adsorção e o modelo Kühn permitiu o melhor ajuste aos dados experimentais, considerando todos os parâmetros estatísticos e a distribuição aleatória (randomizada) dos resíduos simultaneamente. Investigou-se o efeito da aplicação desse filme, por meio de análises físico-químicas ao longo do amadurecimento da fruta, quando usadas diferentes concentrações de extrato de pitomba. Constatou-se que os parâmetros L, C e h são capazes de expressar as mudanças de cor durante o amadurecimento tanto na casca, quanto na polpa. O teor de sólidos solúveis totais está intimamente relacionado com o amadurecimento da fruta e encontrou-se na faixa de 8,77 a 11,95º Brix onde apenas uma formulação não foi capaz de atender a quantidade mínima de ºBrix de mamões maduros, aptos à exportação. O teor de licopeno foi de 12,28 a 25,79 μg licopeno/g de mamão para as análises no dia final. A perda de massa em todos os casos foi inferior a 10%, mas as perdas mais significativas estavam relacionadas com a presença de doenças pós-colheita. Como conclusão, observou-se que concentrações de extrato de pitomba a partir de 10% seriam capazes de reduzir as doenças pós-colheita presentes e retardar o amadurecimento do mamão, sendo atrativo para o mercado externo. 2021-08-11T11:51:45Z 2021-08-11T11:51:45Z 2021-04-09 bachelorThesis VENANCIO, Camila da Silva.
