Influência da temperatura de armazenamento da própolis de três regiões do Estado da Paraíba.

Abstract

Propolis is a bee product of complex chemical constitution, the be es harvest the drops and particles expired buds and flower buds, which bind to other substances and secretions become a rich resin, with various purposes of use by bees. The overall objective was to evaluate the influence of cold storage of the propolis types harvested in the litoral, curimataú oriental and alto sertão regions, in the State of Paraíba, under controlled temperature. Sixty samples of propolis were analyzed; 20 of each region, divided into two groups A and B, 30 samples from group A were submitted to cold storage at 10ºC for a period of 12 months; the samples of group B were collected and immediately submitted to the analyzes, at room temperature. It was possible to conclude that the quantified bioactive value of the phenolic contents for the e xtracts of the red, green and brown propolis, being the extract of the red propolis which presented the best levels, thus guaranteeing its excellent quality as a function of the region, the brown propolis showed levels in its contents of phenols unaltered to storage for a period of 12 months at constant temperature of 10ºC, the values found are above average compared to results found throughout the country, presented an extraordinary quality.
