The research presented in this paper explores the critical aspects of determining the perception of consumers regarding organic food products and the influence of this perception on their purchase behavior in Tiruchirappalli district, Tamil Nadu. This district is a part of India’s Tier-II city and is characterized by the relative absence of organic food consumption despite a reported demand for such products. In this study, the Theory of Planned Behavior and Theory of Reasoned Action were used to develop a theoretical model that was applied to the data collected from participants in order to identify potential relationships between such variables as health consciousness, environmental awareness, concerns about food safety, the quality of products, price and availability, subjective norms, and green advertising. In addition, the effects of age, gender, income, and education on the mentioned variables were analysed. The results of the conducted research demonstrate that health consciousness, concerns about food safety, and perception of product quality play the most significant role in forming consumers’ perceptions of organic food products, while the availability and price of these products have little effect on this variable. At the same time, the perception of organic food products influences the likelihood of purchasing them, which is reinforced by income and education. The study’s findings offer a new insight into the area of organic food consumption, including the creation of a theoretical model that can be a useful guide for future studies in this sphere...
