Abstract: HACCP System is applied in the production of clear apple juice concentrate for export. All Hazards which affect the food safety in the production of apple juice concentrate were studied, and 5 critical control points (Receiving material, Sorting, Pasteurization Ⅱ,Filtrating ,Checking Seal) were determined. Every critical limit was set on the ground of experience and experiment. The action of monitoring and correction was established. And we explain and analyze HACCP system so as to effectually use it, thus we can achieve the food safety of clear apple juice concentrate.
