Efeito da lavagem da casca e do uso de coberturas artificiais na qualidade de ovos comerciais de galinha

Abstract

The purpose of this study is to examine the impact of eggs shell washing and the use of artificial covers on commercialized eggs. Mineral oil and orange peel oil were the artificial coatings chosen to be submitted to the test, both have the main objective of providing protection, hindering the entry of pathogens into the eggs and reducing the gas exchange that occurs between eggs and the environment where they are stored. This, as a consequence, results in na increase in storage time. To perform the evaluation, the eggs were divided into four groups and stored at the same temperature. Group 1 was the control, Group 2 was submitted only to eggs shell washing, Group 3, in addition to having undergone eggs shell washing, received mineral oil covering, and Group 4, after washing, received orange peel oil covering. The analyses were performed at 15 day intervals, starting with the evaluation of the fresh eggs, followed by a second analysis after 15 days to assess whether the internal quality remained the same. Based on the analyses, it was possible to determine that the eggs that went through the process of covering by an artificial cover obtained an excellent quality until the last analysis, which was carried out with 15 days of laying. All in all, orange peel oil had a characteristic orange smell, both externally and internally, and could be pleasant to some people and unpleasant to others.
