| Research backgroundFood nutrition information is an effective means to disseminate nutrition knowledge and obtain trade competition.In the process of China’s reform and opening up, food nutrition information has become an effective vehicle for many enterprises to promote products.So it is necessary to guide appropriate nutrition claims and advertising through regulations and standards.Since 2000,China began to move forward with analysis of the status quo of pre-packaged food nutrition labels, compliance research, development of a series of standards work.Under the support of Healthe and Family Planning Commission, "pre-packaged food nutrition labels General" began to carry out as a guiding document in 2008.In 2011, "national food safety standards of pre-packaged food nutrition labels General" (hereinafter referred to as "General", GB28050-2011) was formally promulgated, and on January 1,2013 formally implemented.After nearly five-year transition period, the enterprises experienced no marking→voluntary labeling→mandatory labeling.However,an effective evaluation for standards and regulations need to be based on a regular or long-term status of implementation, compliance, economic and other aspects of the assessment. Therefore, this study is to carry out a precision and accuracy research for pre-packaged food nutrition label in the early implementation of standards, in order to understand the level of understanding and enforcement of food production enterprises, and analyses the main ways and reasons of errors,and provide recommendations for further improment. In addition, it hopes to arrangement datas for "food serving", and to accumulate data for put forward adequate intake.ObjectiveCollect the nutrition label on the pre-packaged food in the markets and check the basic situation of nutrition label of different food from 2012 to 2013.MethodsChoose Beijing, Hei Longjiang, Henan, Zhe Jiang and Guangzhou as the survey site, than collect the pre-packaged food produced locally. Beijing collect in 2012,and other survey site collect in 2013. More than 800 nutrition labels are collected in each survey site and record the information of the label including the name of the food,nutrient content,units,rounding interval,threshold"0",nutrition format,claiming patterns,weight values,etc.Set up a database with the software Epidata and analyze data with SPSS 18.0.The research include three aspects:1, Compare the information collected with the constraint conditions in the rule.Verify the nutrition label:The labeling rate of food, nutrition facts pattern, the correct rate of labeling, the error message and other information.2, Select 60 samples per province which 30 species was selected randomly and 30 was designated, compare the nutrition value tested by laboratory and the value labeled on the food, analyze the accuracy of labeling. 3, Separate the food in different categories by the information in the database, analyse the mode, P25, P75 of each category, and discuss the results according to foreign standards.Results5833 foods are collected in this survey, including:cereals, snacks snacks, nuts, soy products and so on.The rate of labeling in 2012 is 91.9%, the correct rate of 69.8%. The rate of labeling in 2013 is 98.7%, the correct rate of 80.1%.The dairy products have the highest correct rate of 90.8 percent; the pices and soy lowest have the iowest rates of 64.0% and 65.4%. The labeling rate and accuracy of the nutrition labeling in 2013 are significantly higher than in 2012.The mistakes in the label focused on the name, units, rounding interval and threshold"0".The content and comparison claim are unmatched with the rule and the function claim was ill-formed or exceeded.Check the coherence of label and laboratory data,only 106 samples are fully qualified and the qualified rate is 48.2%.The coincidence rate of protein is 95.5%,which is highest.The rate of sodium is lowest among the nutrient,especially in snacks and drinks.The serving rate of food is 32.2%. Separate the food in different species and 21 of them were consistent with the nutrition recommendations in Canada while 14 were inconsistent.The reason of inconsistent mainly is the differences of diets and consumption and the misunderstand of the concept.ConclusionsDuring the period of GB 28050-2011 are carried out, the current situation of China’s market is better, but the phenomena of non-standard is still exist,and the changes is required by companies. The relevant departments should lead and educate the companies correct rule and change the unmatched situation.In China, the serving data is incomplete and more survies willing be needed to complete the data and improve the regulation standards. |
