In today’s society, the consumption of organic products presents both significant benefits and potential barriers, as evidenced by the intrinsic and extrinsic factors shaping consumer behavior among university-aged millennials. This study explores the motivators influencing consumer behavior toward organic product purchases and identifies barriers that may inhibit university-aged millennials from engaging in such consumption practices. Utilizing a qualitative research approach, data were gathered through semi-structured interviews with thirty-eight university students in Ecuador and Peru. The analysis employed Grounded Theory methods. The findings of this research indicate that intrinsic factors, including environmental awareness, eco-consciousness, habitual tendencies, health considerations, and personal values, in conjunction with extrinsic factors, such as familial and social influences and concerns regarding the COVID-19 pandemic, are significant drivers of the adoption of organic goods. Conversely, challenges related to product availability, cost implications, and prevalent skepticism occasionally hinder the acquisition of these products. An innovative aspect of this study lies in its pioneering use of Grounded Theory in Ecuador and Peru. It sheds light on millennials’ perceptions of organic products and elucidates the factors influencing their purchasing decisions in the organic market.
