Effects of addition of swine skin on the technological characteristics of mortadella produced in an industrial unit
The aim of this work was to evaluate the effects of the addition of swine skin on the technological characteristics of mortadella formulations produced on industrial scale. The effects of concentrations of swine skin (1.5 to 5.5 %) and sodium chloride (2 to 3 %) on total protein, total fat, starch, moisture, water activity, sodium, pH and texture profile (hardness, adhesiveness, elasticity, cohesiveness and chewiness) were evaluated and compared to a mortadella formulation without swine skin addition. The mortadella formulations with addition of 3.5 to 5.5 % swine skin and 2 to 2.5 % sodium chloride are in accordance with Brazilian legislation and provided an increase of approximately 12 % in protein content, a decrease of 14 % in sodium content and a water activity less than 0.9488. The swine skin and sodium chloride provided stability to the mortadella and influenced its texture, mainly in hardness, elasticity and chewiness.
期刊介绍：
he International Journal of Food Studies (IJFS), a journal of the ISEKI_Food Association, is an international peer-reviewed open-access journal featuring scientific articles on the world of Food in Education, Research and Industry. This journal is a forum created specifically to improve the international dissemination of Food Science and Technology knowledge between Education, Research and Industry stakeholders. Original contributions relevant to the following topics will be considered for publication: -Education methods, including Life Long Learning and e-learning; -Research and application in academia, research, industry; -Critical reviews of scientific literature by researchers, students, invited authors; -Exchange of views and opinions of a scientific nature including testimonies on career experiences in Food Industry/Research/Education (required skills, challenges and successes). Manuscripts focusing on Food related Education topics are particularly welcome.
