Parâmetros de qualidade da polpa de pequi de diferentes localidades do Norte de Minas Gerais

Abstract

The objective of this study was to evaluate the quality parameters of pequi pulp from different locations in the North of Minas Gerais. Samples of pequi pulp were collected in the 2019/2020 harvest in six communities in the Municipalities of Bonito de Minas, Januária, São João da Lagoa, Cônego Marinho and Ibiaí. Analyzes of centesimal composition, color and firmness were performed. The data was submitted to variance analysis and when the "F" test was significant, the averages for the different locations were compared by Tukey test at 5% probabilty. A multivariate statistical analysis was also performed using principal component analysis and factor analysis techniques. It was observed that there was a statistical difference for centesimal composition in all variables analyzed and that the Sambaíba locality, in the Municipality of Januária, presented lower moisture content than the other locality and, consequently, higher values of dry mass, ash and proteins. The Municipality of São João da Lagoa presented higher moisture content in relation to the other municipalities, however, the dry mass, lipids, ash contents were lower and the protein content with an intermediate value. On the other hand, the Municipalities of Bonito de Minas, the Communities of Peruçu and Sambaíba in the Municipality of Januária, the Municipality of Cônego Marinho and Ibiaí, presented intermediary centesimal composition values to the other locations. There were no statistical differences in the parameters L* and Hue, indicating that the average of the six locations is the best estimated for these, with the value of 68.03 for the parameter L* and 82.33 for Hue. For the parameters a*, b* and chroma there were statistical differences. For the analysis of firmness, there were statistical differences between the different localities studied, and the localities of Bonito de Minas, the Sambaíba Community in the Municipality of Januária and the Municipality of São João da Lagoa presented the highest values followed by the Peruaçu Community in the Municipality of Januária and the Municipalities Cônego Marinho and Ibiaí with the lowest values. Considering the results found for the variables studied, it was concluded that the pequis of Januária - Sambaíba locality presented better chemical and physical characteristics, indicating the presence of standardization in the processing of pequi pulp.
