Summary: | The objective of this research was to evaluate the inside changes quality of fresh ostrich eggs and eggs stored in ambient temperature (25[degre]C) and in cooling condition storage (5[degre]C), during 3, 7, 14, 21 and 28 days after storage. There was a considerable slump at Unity Haugh, pH increasing and viscosity decreasing related to time storage. Eggs stored in ambienttemperature showed more alterations than the ones stored under refrigeration. There was an increasing loss of weight during the days of storage in ambient temperature and in cooling condition storage, although the loss of weight was more notable in the ambient temperature. Key words: eggs, ostrich, unit Haugh, storage, albumen. O objetivo deste trabalho foi avaliar as alteracoes da qualidade interna de tres tipos de ovos de avestruzes: frescos, armazenados sob temperatura ambiente (25[degre]C) e sob temperatura de refrigeracao (5[degre]C), durante tres, sete, 14, 21 e 28 dias de armazenamento. Houve queda significativa na Unidade Haugh, aumento do pH e diminuicao da viscosidade em relacao ao tempo de armazenamento. Os ovos mantidos em temperatura ambiente apresentaram maiores alteracoes do que os ovos armazenados sob refrigeracao. Houve uma crescente perda de peso durante os dias de armazenamento, tanto sob temperatura ambiente, quanto em temperatura refrigerada, porem a perda de peso foi mais evidente na temperatura ambiente. Palavras-chave: ovo, avestruz, unidade Haugh, armazenamento, pH do albumen. |
