Consumers who buy organic products not only consume them free from chemical residues, they also consume products with high nutritional value in contrast with conventional or genetically modified products. However, here and in other countries just as there are many factors to motivate purchasing of organic products, there are also factors that prevent purchasing them. Positive factors motivating the purchase of organic products have been identified as follows: environment friendly methods of production and consequent lack of chemical residues and hormones in products, higher nutritional value, and more delicious taste. On the other hand, negative factors affecting the purchase of organic products have been identified as follows: expensive, limited availability, relatively short shelf life, unappealing appearance, and the unfamiliarity of organic logos. But if organic foods are consumed more, organic agriculture will develop in parallel and it will be easier and cheaper to for consumers to purchase them. In this way, the existing price difference between organic and conventional products will also decrease. Therefore the purpose of this study was to identify the factors affecting consumers’ buying habits of organic products by examining the relevant studies in our country and abroad.
