Abstract: The present study aimed to sensorially evaluate cream cheese made from different genetic variants of bovine milk β-casein (A1A1, A1A2, and the A1A1 + A1A2 combination) to identify the formulation with the highest consumer acceptability. Three cream cheese formulations were developed: F1 (100% A1A1 milk), F2 (100% A1A2 milk), and F3 (50% A1A1 milk and 50% A1A2 milk). Sensory analysis was conducted with 80 untrained panelists, who evaluated attributes such as appearance, aroma, taste, texture, color, and overall acceptability, as well as purchase intention, using structured scales. The results indicated that cheese F2 (100% A1A2 milk) had the highest acceptability across all sensory attributes, showing the highest scores for appearance (88.7%), taste (85.37%), and overall acceptability (86.48%). Cheese F3 (A1A1 + A1A2 mixture) also showed good acceptability, with results superior to cheese F1 (100% A1A1 milk), which had the lowest acceptability scores. Purchase intention followed the same trend, with consumers showing greater interest in cheeses made from A1A2 milk. From a nutritional perspective, all formulations showed similar characteristics, with cream cheese being considered a good source of calcium, containing 214 mg per 100 g. It is concluded that using A1A2 milk in cream cheese production improves sensory acceptability and increases the likelihood of purchase by consumers, representing a promising opportunity for the dairy market.
