Abstract

Eggs are foods with almost perfect proteins, while also containing nutrients with high biological value. The purpose of this study was to evaluate the morphological structure, physical-chemical, nutritional, and microbiological parameters of commercial and free-range eggs sold in the municipality of Santarém, State of Pará, Brazil. The two types of eggs were also compared to check for any differences in quality. The evaluations were conducted on variables such as Haugh unit, weight loss, egg width and length, specific gravity, yolk and albumen dimensions, pH, among others. A total of 240 eggs were purchased in the Brazilian municipality of Santarém (2º45’06” S and 54º70’09” W). A statistical study was also performed using the BIOESTAT 5.0 statistical program. A comparison of the industrial and free-range eggs and their various parameters is given in the tables along with the coefficient of variation. The results obtained were satisfactory and showed that the quality of eggs is affected more by environmental factors than by the source from which they are obtained. The results were also compared to previously published literature, and it was determined that this study offers a better foundation for the nutritional examination of egg quality.
巴西圣塔姆市售鸡蛋质量分析
鸡蛋是一种蛋白质几乎完美的食物,同时还含有高生物价值的营养物质。本研究的目的是评估在巴西帕尔州圣塔姆姆市销售的商品鸡蛋和散养鸡蛋的形态结构、理化、营养和微生物参数。研究人员还对这两种鸡蛋进行了比较,以检查其质量是否存在差异。评价指标包括哈氏单位、失重、鸡蛋宽度和长度、比重、蛋黄和蛋白尺寸、pH值等。在巴西圣塔姆姆市(2º45 ' 06 " S和54º70 ' 09 " W)共购买了240个鸡蛋。还使用BIOESTAT 5.0统计程序进行了统计研究。表中给出了工业鸡蛋和散养鸡蛋的比较及其各项参数,并附有变异系数。结果表明,环境因素对鸡蛋质量的影响比对鸡蛋来源的影响更大。结果还与先前发表的文献进行了比较,确定本研究为鸡蛋质量的营养检查提供了更好的基础。

期刊介绍: A Revista Brasileira de Ciência Avícola surgiu em 1999 a partir da necessidade que a comunidade científica possuía de um periódico para veiculação e publicação de seus trabalhos, com a publicação de três números anuais. A Revista conta hoje com um corpo editorial altamente qualificado e com artigos científicos desenvolvidos pelos maiores especialistas da área, o que a cada dia atrai mais leitores em busca de inovação e respaldo técnico. Devido à credibilidade que conquistou pelos esforços de sus autores, relatores e revisores, a Revista ganhou caráter de coleção, sendo consultada como fonte segura de estudo desenvolvidos na Avicultura. A partir de 2003 – volume 5 -, a Revista passou a chamar-se Brazilian Journal of Poultry Science, e todos os trabalhos passaram a ser publicados em inglês. No mesmo ano subiu para quatro o número de revistas por volume, ampliando-se assim os trabalhos publicados anualmente.
