Objective To establish the contact surface area/volume ratio of different types of food contact material (FCM) in contact with liquors. Methods A total of 1 196 kinds of liquor consumed by Chinese population was collected in this study. Food contact area was calculated by direct measurement or 3D area measuring instrument. The contact surface area/volume ratio (S/V) was obtained by combining contact area with food packaging volume. Results 97.4%(1 165/1 196) of FCM in contact with liquor was made of single material, mainly glass and ceramics. The remaining 2.6%(31/1 196) was made of composite materials, mainly plastic and coated aluminum cans. The S/V of FCM in contact with liquor ranged from 2.84 to 19.67 dm²/kg. Further analysis found that 96.7%(1 156/1 196) of the S/V was greater than 6 dm²/kg, 81.9%(979/1 196) was ≥7.0-9.0 dm²/kg. Conclusion The majority of S/V in contact with liquor was higher than 6 dm²/kg, a parameter used by European Food Safety Authority(EFSA). Food contact S/V constructed by investigation can decrease uncertainty in food contact material risk assessment.
