The objective of this study was to determine the effect of different melt holding time (0–20 min) at a melting temperature of 90 °C on the viscoelastic properties of full-fat (fat content in dry matter 50 g/100 g, dry matter content 35 g/100 g) processed cheeses over the course of a sixty-day storage period (6 ± 2 °C). Three various agitation speeds (1000; 1500 and 3000 rounds per min) were used. For all three monitored agitation speeds, there was a significant decrease in the firmness of the processed cheeses in the first 3 min of the holding time. The subsequent extension of the melt holding time (up to 20 min) led to the significant increase the product firmness. Over the course of a sixty-day storage period, the firmness of all the monitored processed cheeses increased. Samples produced at 3000 rpm were significantly more solid in comparison with processed cheeses produced at lower agitation speeds (1000 and 1500 rpm).
