Qualidade da manteiga de garrafa comercializada às margens da BR-230 no Estado da Paraíba.

Abstract

In this research 51 samples of “manteiga de garrafa” were analyzed obtained in all the sale points located along BR230 in the Paraíba State Brazil in order to determine your quality, being evaluated the parameters: labeling and packings, the microbiologics and the physical chemical. When evaluating the adaptation of the labeling and packing of the “manteiga de garrafa” in agreement with the legislation. Of these 7 only possessed labels. The material of the packings 50 they are glass bottles and 1 it is bottle of plastic type PET, with 50 of capacity of 500 mL and 1 of 220 mL. The covers they were new and of plastic material. However two of them were defective, presenting broken parts and four was too much dirty. In the microbiologic study tried to be determined the total count of mesophyllous, the most probable number of total coliforms, the most probable number of thermotolerants coliforms and count of Staphylococcus aureus positive coagulase. Among the studied samples, it was not obtained bacterial growth. These results are due to the processing of the product, that goes by great heating and it is still wrapped in discharges temperatures. The butter of bottle of this study is like this capable to the human consumption in what it concerns the microbiologic characteristics. In the physicalchemical evaluation of “manteiga de garrafa”. It was evaluated the titratable acidity, fat tenor, pH, nogreasy solids, humidity tenor and Kreiss reaction. The titratable acidity 0.73% to 2.69%; the fat tenor varied from 96.04% to 99.91%; the pH varied from 2.05 to 4.51; the nogreasy solids varied from zero to 3.78%; the humidity tenor oscillated from 0.06% to 0.48%; the Kreiss reaction was positive in 22 (43.14%) samples. Only 6 (11.76%) samples didn't present any unconformity among the ones that they were out of the patterns, 11 (21.57%) they presented unconformity in 1 parameter; 19 (37.25%) in 2; 12 (23.53%) in 3; 2 (3.92%) with 4 and with 5 only 1 (1.96%) sample. The parameter more unconform was the nogreasy solids with 32 (62.75%), the Kreiss reaction with 29 (56.86%), they are the acidity and the fat tenor with 16 (31.37%) and the humidity with 5 (9.80%). It is ended that the labeling presents great unconformity, that the used packings are inadequate, and that the “manteiga de garrafa” presents excellent microbiologics characteristics; however it doesn't assist the physicalchemical requirements stipulated by the legislation.
