Acrylamide is a process contaminant and neurotoxic with growing evidence of cancer in human. Potato-based products majorly contribute towards acrylamide dietary intake thereby posing major food safety threat that necessitates formulation of acrylamide reduction strategies. This review highlights the recent research work on acrylamide formation mechanism, dietary intake, toxicity and potential reduction strategies at various levels in the food supply chain to ensure safety of potato-based products. Acrylamide formation in potato-based products depends on several factors involved in potato supply chain. Depending on the variety, application of nitrogen and sulphur fertilization may show positive, negative, or no effect on acrylamide formation. Heat and water stress faced by potato crops may increase the risk of acrylamide formation in processed products. Various pre-processing (e.g., blanching, chemical treatments etc.) and processing (e.g., methods, temperature, time) strategies may also reduce acrylamide formation (37–98%) in potato-based products at commercial and domestic levels. The acrylamide reduction strategies from farm to fork level have been discussed with special emphasis on mechanism of chemical treatments with pictorial representation.
