The purpose of this study was to establish the degree of ripening of natural goat cheese used as a raw material; to formulate a spreadable processed cheese with creamy consistency; and to determine the level of each process variable.
Cheeses of various ripening times were selected for the formulation through cluster analysis. The effect of the final moisture was studied using the same proportion of fresh and ripened cheeses in the formulation, and three melting temperatures were tested.
Goat cheeses ripened for 10, 20 and 40 days were chosen for the formulation of spreadable processed cheese. Final moisture content of 63.0 ± 0.1 per cent was selected (p = 0.0008). Melting temperature at 85.0 ± 0.1°C for 9.0 ± 0.5 min was suitable to homogenize the cheese mass (p = 0.001). The level of variables was validated by changing the proportions of natural goat cheeses selected. Four formulations were obtained with a consistency similar to that of the commercial reference.
Processed cheese is produced by blending shredded natural cheeses of different types and degrees of ripening. The use of ripening goat cheeses as a raw material in processed cheeses contributes to the added value of the local goat milk chain. Goat cheeses have an acid and slightly salty taste and medium to long persistence.
The results of this work can be used by processed cheese manufacturers to better understand the impact of goat cheese ripening on processed cheese quality. The industry can also use these results to introduce the product onto the market and plan their marketing campaign.
