Consumers' purchase decision based on intrinsic and extrinsic factors related to food safety issues: A review

Abstract

Food Safety issues have been arising around the world and have led to many adversarial effects to consumers. Purchasing decisions has become more complex as it is impacted by many intrinsic and extrinsic factors that triggered changes in consumers' behaviour. Few reviews have been conducted on the intrinsic and extrinsic factors related to food safety on consumers' purchasing decisions. According to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA Statement) procedure and Web of Science (WoS) as the main database, 25 related studies were identified. Furthermore, these articles resulted with two main types of consumers' purchasing decisions that lead towards consumer satisfaction which are willingness-to-pay and purchasing intention. These two themes were further analysed to identify food safety factors which produce several intrinsic and extrinsic factors including consumers' characteristics, role of media, product characteristic, credence attributes and supply chain actors. Several recommendations are suggested for future in qualitative and quantitative studies, to produce a standard methodology for review in research synthesis in the context of consumers' purchasing decision and food safety such as tracking of citation and reference searching techniques.
