Ozônio e radiação ultravioleta na higienização da casca de ovos comerciais /

Panini, Anselmo Rodrigo January 2019 (has links)
Orientador: Marcos Franke Pinto / Resumo: O Brasil é um dos maiores produtores de ovos do mundo e devido ao fato desse alimento estar cotidianamente na mesa do brasileiro, um controle contínuo e rigoroso deve ser desenvolvido a fim de garantir sua qualidade físico-química e microbiológica. Neste estudo foi avaliada a qualidade microbiológica e físico-química de ovos frescos submetidos a metodologias alternativas para desinfecção da casca. Foram realizadas diversas combinações de tratamentos, utilizando a lavagem dos ovos com água clorada e água ozonizada, e a exposição dos ovos ao gás ozônio e à radiação ultravioleta (UV), e foi avaliado seu efeito em comparação a ovos não higienizados. Após os tratamentos, os ovos foram submetidos à contagem total de microrganismos mesófilos aeróbios e facultativos viáveis e à contagem de coliformes a 30-35oC.Também foi avaliado o efeito dos tratamentos no comportamento dos parâmetros físico-químicos de qualidade dos ovos armazenados sob refrigeração e a temperatura ambiente. Todos os tratamentos foram eficazes na redução da contaminação microbiana da casca dos ovos. A exposição à luz U.V. e ao gás ozônio, sem lavagem prévia dos ovos, não diferiu dos tratamentos nos quais os ovos foram lavados com água clorada, que é o procedimento normalmente empregado na higienização dos ovos. A qualidade dos ovos durante o armazenamento abaixo de 4ºC e a 25ºC foi avaliada durante 28 dias por análises semanais de unidade Haugh, índice de gema, pH e pela perda de peso dos ovos. Não houve diferença ...

In this study, the microbiological and physicochemical quality of fresh eggs submitted to alternative methodologies for disinfecting the shell was evaluated. Several combinations of treatments were performed, using egg washing with chlorinated and ozonated water, and egg exposure to ozone gas and ultraviolet radiation (UV), and their effect was evaluated comparing with not sanitized eggs. After treatments, the eggs were submitted to total count of viable mesophilic aerobic and facultative microorganisms and 30-35oC coliforms count. The effect of the treatments on the behavior of physicochemical quality parameters of the eggs stored under refrigeration and at room temperature was also evaluated. All treatments were effective in reducing the microbial contamination of eggshell. The exposure of the eggs to U.V. and ozone gas, without previous washing, did not differ from the treatments in which the eggs were washed with chlorinated water, which is the normal procedure used in the hygiene of the eggs. Eggs quality during storage below 4°C and at 25°C was evaluated for 28 days by weekly Haugh unit, yolk index, pH and weight loss analyses. There was no significant difference between the treatments, but the temperature was determinant for egg ... (Complete abstract click electronic access below) / Mestre
