Quality measurements of cuiabana-type pork sausages added with brewing by-product flours

The objective of this study was to evaluate the replacement of part of the pork from Cuiabana sausage by a brewery by-product on the physicochemical and microbiological properties during storage. Brewery by-product (BW) concentration influenced sausage colouration, with reduced luminosity, L*: 52.060 in the 6% (w/w) treatment compared to the 0% treatment controls (L*: 63.956). Titratable acidity showed higher (1.162 g/100 g) compared to the 0% treatment controls (1.093 g/100 g) of lactic acid. Proteins and total enzymatic fibers increased, 19.068 and 9.233 g/100 g of sample respectively. It was observed that the by-product did not interfere in the oxidation of the lipids and the best model to describe the oxidation of lipids is Van Bertalanffy model (P < 0.05). Escherichia coli and Staphylococcus sp. levels were within the prescribed limits and Listeria monocytogenes colonies were observed. The addition of by-products had no interference on the formation of oxidation compounds in the sausage and has increased fiber content.

Automated summary

The study found that replacing part of the pork in Cuiabana sausage with brewery by-products can alter the color, increase protein and enzymatic fiber content, without affecting lipid oxidation. Additionally, at the microbiological level, the presence of Listeria monocytogenes should be noted, although levels of Escherichia coli and Staphylococcus sp. were within acceptable limits.
