PADRONIZAÇÃO DA HIDRATAÇÃO DA TRIPA USADA NA PRODUÇÃO DE MORTADELA TIPO BOLOGNA PARA CONTROLE DE REPROCESSO

Abstract

Between the months of September 2023 and March 2024, data was analyzed from the Bologna-type smoked mortadella production line. This analysis showed a high rate of reprocessing related to casing bursting, and a difference in color between the casings. two casings used by the company after cooking the product. Therefore, the main objective of this work was to identify, through tests and comparisons, the root cause of the increase in the reprocessing rate due to casings bursting in mortadella and the difference in color of the mortadella. Initially, tests were carried out on the hydration of the tripe with time variation keeping the temperature constant, and with temperature variation with constant time for both Tripe A and Tripe B, in order to investigate whether the time and temperature of the water hydration influenced the resistance of the casing. It was noticed during the monitoring of the production line that there was a difference in the color of the products with the change in the casing model. It was also observed that the mortadella transport cages waited for a long time at room temperature before being sent to the greenhouses, therefore a waiting time test was carried out to verify that this condition did not interfere with the difference in color of the mortadella packaged with different casings. . It was observed that both the time and temperature of hydration had an influence on the resistance of the casings, with significant differences between Casing A and Casing B. Of 1900 mortadella evaluated that were embedded with Casing A, there were only 8 bursts and 7 losses. , already with casing B of 1200 mortadella embedded, there were 43 explosions and 21 losses recorded. It was observed that the waiting time for the products before going to the greenhouse was not altering the color of the product. The analysis and update of operational procedures, together with the adoption of new practices in the hydration tank, resulted in a reduction in the time the casings were immersed in water, which helped to minimize the risk of bursts. However, it is essential to maintain compliance with established operating procedures and have a clear understanding of the specifications for each type of casing to ensure its strength and reduce the need for reprocessing.
