Abstract

The local cheese factories currently use bovine commercial starter cultures, and the spreadable cheese process is not standardized. A detailed understanding of the effect of pasteurization temperature, starter culture, and incubation temperature must allow producers to optimize the process, increase cheese yield, and improve the quality of the final product. The main objective of the study was to describe the preparation method of spreadable goat cheese and investigate the effects of specific processing conditions (pasteurization temperature, starter culture, and incubation temperature) on the composition, yield, rheology, and sensory characteristics of the final product. Results showed the impact of pasteurization temperature, starter culture, and incubation temperature on spreadable goat cheese. The results indicated that it is possible to improve cheese yield, rheological properties, and sensory analysis when milk is pasteurized at 75°C for 30 minutes; cheese yield can also be improved by lowering incubation temperature to 37°C. Cheeses made with autochthonous starter culture showed better sensory characteristics and higher pH compared to the cheeses made with commercial culture.
