Resumo: | Crimson Seedless Grapes (Vitis vinifera L.) is one of the most important seedless variety, due to its attractive bunch medium, and large dark pink berries. It features excellent sensory characteristics due to its firm texture and crisp flavor that varies from sweet to neutral and uniform color. Stands out as the second most important seedless variety of the São Francisco. Osmotic dehydration is presented as a good alternative to reduce the water activity of this grape, allowing its storage for long periods and improving its stability and quality. This study aimed to relate the influences of different parameters for efficient osmotic dehydration of fruit, in order to reduce post-harvest losses as well as offer new alternatives for the producer. To optimize the osmotic dehydration preliminary test was conducted with independent variables: temperature (T) (20ºC to 40ºC), immersion time (t) (0.5 to 4.0 hours, with breaks every 30 minutes) and concentration of osmotic solution (C) (35ºBrix, 50ºBrix and 60ºBrix) was the dependent variable moisture loss (ML). Then 26-2 fractional design was used, having as independent variables: T (30ºC and 50ºC), t (1.0 and 4.0 hours), NaOH (0% and 2%), bleach (0 and 1 minute), perforated in the fruit (0 and 16 holes/cm2) and C (30ºBrix and 60ºBrix) and the dependent variables and solids ML and incorporation of solid (IS). Proceeding was conducted a factorial design 23, with independent variables: T (30ºC to 50ºC), t (1 to 4 hours) and C (40ºBrix to 50ºBrix), being constant bleaching (30 seconds) and perforated (8 holes/cm2); the dependent variables were ML, IS and DEI (Dehydration Efficiency Index). The best conditions for osmotic dehydration using DEI as a parameter was the application of bleach for 30 seconds, 8 holes/cm2, osmotic solution at 42ºBrix, immersion time of 1.6 hours and temperature of 46 ° C. The response surface models obtained were predictive of ML and IS, except for DEI. The product selected best set Page's equation (R2 = 0.995). |

Apresenta característica sensorial excelente devido a sua textura firme e crocante, sabor que varia do doce ao neutro, e coloração uniforme. Destaca-se como a segunda variedade sem semente mais importante do Vale do São Francisco. À desidratação osmótica apresenta-se como boa alternativa para reduzir a atividade de água desta uva, permitindo o seu armazenamento por períodos longos e melhorando a sua estabilidade e qualidade. Esta pesquisa teve como objetivo relacionar as influências de diferentes parâmetros para um eficiente processo de desidratação osmótica deste fruto, com a finalidade de reduzir as perdas pós-colheita como também oferecer novas alternativas para o produtor. Para otimizar a desidratação osmótica foi realizado ensaio preliminar com as variáveis independentes: temperatura (T) (20ºC a 40ºC), tempo de imersão (t) (0,5 a 4,0 horas, com intervalos a cada 30 minutos) e concentração da solução osmótica (C) (35ºBrix, 50ºBrix e 60ºBrix); sendo a variável dependente perda de umidade (PU). Em seguida foi aplicado planejamento fracionado 26-2, tendo como variáveis independentes: T (30ºC e 50ºC), t (1,0 e 4,0 horas), NaOH (0% e 2%), branqueamento (0 e 1 minuto), perfurações no fruto (0 e 16 perfurações/cm2) e C (30ºBrix e 60ºBrix); e as variáveis dependentes PU e incorporação de sólidos (IS). Prosseguindo foi realizado um planejamento fatorial 23, com variáveis independentes: T (30ºC a 50ºC), t (1 a 4 horas) e C (40ºBrix a 50ºBrix), sendo constante o branqueamento (30 segundos) e perfurações (8 perfurações/cm2); as variáveis dependentes foram PU, IS e IED (Índice de Eficiência de Desidratação). As melhores condições para a desidratação osmótica utilizando o IED como parâmetro foi a aplicação de branqueamento por 30 segundos, 8 perfurações/cm2, solução osmótica com 42ºBrix, tempo de imersão de 1,6 horas e temperatura de 46ºC. Os modelos de superfície de resposta obtidos foram preditivos para PU e IS, exceto para o IED. O produto selecionado ajustou melhor a equação de Page (R2 = 0,995).Submitted by (edna.saturno@ufrpe.br) on 2016-07-27T11:28:24Z No. of bitstreams: 1 Maria Anunciada Leal Porto.pdf: 1114756 bytes, checksum: 0011c80ff1bdc5f6d7a48254d4913f7a (MD5)Made available in DSpace on 2016-07-27T11:28:24Z (GMT).
