Determination of the Effect of Different Energy Classes of Household Refrigerators on the Freezing Process and the Quality Characteristics of Beef

Journal of Food Processing and Preservation, Volume 2024, Issue 1, 2024.
The household refrigerator model used for freezing processes in this study was produced in the factory in different energy classes (C, D, and E). Equal amounts of beef (10 × 10 × 2 cm; 2 × 2 × 2 cm) and minced beef (10 × 10 × 2 cm) were placed in refrigerator bags before freezing.
