Abstract
The study aimed to enhance Hatay cheese texture using microbial transglutaminase enzyme (mTG). Cheeses were manufactured using milk treated with mTG for different durations (30, 45 and 60 min) and assessed over 60 days. Longer treatment increased yield (18.79–20.81%) and hardness but reduced springiness. Composition, proteolysis and adhesiveness remained unaffected. Electrophoresis showed β-casein and αs1-casein declines during storage, with minor changes in αs1-casein's breakdown product. Microbial transglutaminase enzyme created a denser protein network, visible in SEM, resulting in a compact structure. Sensory analysis favoured the 60-min treatment. Overall, mTG improved Hatay cheese quality by modifying texture without major compositional changes.
期刊介绍:
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
