Abstract:Apple chips are hot-selling leisure food in the market.Hazard analysis and critical control point（HACCP）system was applied in the production of apple chips to improve quality and safety of the final products.Hazard analysis（HA）on apple chip production process was conducted to establish six critical control points （CCP），including raw material inspection and acceptance，screening，color protection，explosion puffing，packing，and inspection.According to the actual production conditions and the experiment data，critical limits（CL）of each CCP，monitoring procedures（MP），and corrective actions（CA）were established.This study would provide a theoretical basis and technical support to improve the product quality of apple processing in China.
