With the improvenment of national living standard and the acceleratecd pace of life,disposable tableware has become China’s food packaging containers are to be used by resicdents Disposable food and beverage has a certain impact on the safety of food.First,the disposable tableware can be packaged and protected food,two is the chemical composition of the food and beverage will be in contact with the food to the food migration.Food and beverage has two key indicators:one is the total migration,the other is the specific migration.Study on cdisposable tableware total migration of chemicals,to help consumers understand and master the use of disposable tableware for attention,through the correct use so as to ensure their own health and safety at the same time,research on specific migration can play a supplementary role.Based on the daily use of disposable catering to the determination of total migration as the research object,its chemical quantity The simulation of liquid food is acetic acid,ethanol,water and hexane,respectively represent acid food,alcoholic drinks,water food,fatty food According to different material tableware,food simulating liquid concentration,soaking time,soaking temperature and other factors as the basis,variation of the overall migration of chemicals Finally the consumer’s daily habits for chemical substances based on disposable tableware may the migration hazard risk assessment,the specific contents are as follows(1)the migration of the migration of chemical substances in disposable food and beverage can be influenced by the concentration of the food,the length of time,the temperature of the soaking liquid,the materials,etc.(2)PE coated paper dinnerware are not appropriate to contain alcoholic food,but safe for short-time packing cold food.PS transparent dinneware are safe under all conditions.PS foam dinnerware are also safe for packing food,but resulting in environmental pollution.Don’t use wax coated dinnerware which are harmful for health.(3)The disposable dinnerware contain plasticizer,more or less.The types of plasticizer mainly include DBP,DIBP and DEHP.The disposable dinnerware also have resolvent substance most found in benzenoid solution.Ethanal exists in any type of disposable dinnerware.Fortunately,heavy metal elements,such as lead,arsenic,chromium,Antimony and germanium,have hardly been found in these dinnerware.Thus,the risk of disposable dinnerware comes from the plasticizer and resolvent substance,less from heavy metal elements.(4)The risk assessment shows that plasticizer,resolvent remnant and heavy metal elements can cause serious impair to people’s health.The possibility of consumer being hurt by phthalate plasticizer in disposable dinnerware is 20%×25%×50%×10%×1%=2.5×10-5,which is at medium level risk.Meanwhile,the risk rate of heavy metal is A,which is tolerant.
