Avaliação da qualidade de pepinos em conserva

Abstract

The objective of this work was to evaluate the physical, physical-chemical characteristics and the labeling of canned cucumbers commercialized in the municipality of Itaqui. The number of cucumbers, determination of diameter and length, gross weight, net weight, drained weight, free space, vacuum, color, pH, total titratable acidity and chlorides were determined. All evaluated canned cucumber labels conformed to the general labeling standards in accordance with the legislation. The values of liquid weight and drained weight were higher than those specified by the manufacturers. The free space ranged from 0.83 to 2.23 cm, the vacuum obtained values between 0 and 8.33 in Hg. The titratable total acidity presented values between 0.48 and 0.92 g of acetic acid / 100 g. The pH for all samples was less than 4.5. The chloride content (g sodium chloride / 100 g) ranged from 1.70 to 3.47. The color parameters indicated that the pickled cucumbers presented a composition of green and yellow color, with tendency to dark / black. It can be stated that the canned cucumbers evaluated are safe, since they presented pH lower than 4.5. However, the commercial brands do not have standard for the other variables, because differences were found in the evaluated parameters.
