Food and Machinery
Objective:This study aimed to provide a theoretical support for enhancing the quality of Hunan flavor marinated beef and improve the marinated process.Methods:The laws of beef quality and flavor change during pulse marinated, vacuum marinated micro pressure marinated and traditional marinated were investigated.Results:The NaCl content and percentage loss from cooked increased gradually in each marinated process beef with increased marinated time. The chromatic difference L* value decreased gradually, and the chewiness, hardness, elasticity increased first and then decreased. The sensory evaluation found the highest score and the time required to reach the highest score of pulse …
