Background: The growing concern with pet health and nutrition has driven the development of functional foods enriched with bioactive ingredients, such as Saccharomyces cerevisiae. Despite its recognized benefits, consumer acceptance, particularly among pet owners, remains contingent on behavioral and perceptual factors, which can be effectively examined through the Theory of Planned Behavior (TPB).
Purpose: This study aims to examine pet owners’ purchase intention toward pet food enriched with Saccharomyces cerevisiae and to analyze how attitudinal, social, and perceived behavioral control factors influence purchase intention and actual purchasing behavior.
Method: A quantitative approach was employed using a structured survey grounded in the TPB framework. Data were collected from a sample of 396 pet owners. The analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM), allowing for the examination of relationships between latent constructs, including attitudes, subjective norms, perceived behavioral control, purchase intention, and actual behavior.
Results: The findings revealed that subjective norms emerged as the strongest predictor of purchase intention, followed by attitudes and perceived behavioral control. Furthermore, purchase intention demonstrated a significant and positive effect on actual purchasing behavior. Pet owners who perceived greater social support and held favorable attitudes toward the functional benefits of Saccharomyces cerevisiae exhibited higher levels of intention to purchase enriched pet food products.
Conclusions: The study highlights the central role of social influence in shaping consumer decision-making in the context of functional pet foods. These results suggest that marketing strategies should prioritize educational and socially oriented communication efforts, reinforcing both the perceived benefits of the ingredient and the normative support surrounding its adoption.
