Ergonomic Study On Production Date Label Of Packaged Food

Production date on the packaged food is a basis standard that the food can be eatensafely or not, the consumers pay more attention to it. As an example of packaged food,the paper discussed the production date marked on food label of packaged food with themethod of paired comparison and performance evaluation and so on. And on the basis,we proposed related design principle on production date label of packaged food.This research contains three sections included six experiments. Study1survey thecurrent situation of production date marked on food label by questionnaire; Study2evaluate the text formatting with the scaling method from efficiencyerror-prone and Satisfaction, to obtain the optimal text formatting; Study3includesexperiment2and experiment3, the purpose of this section is to study the contents of datemarked, One experiment by paired comparison method to judge the favorite date labelcontent,and Experiment3determine the different date contents marked on packagethrough the performance evaluation. Section4includes experiment4and experiment5,Experiment4choices the reasonable date location through subjective judgment methodwith difference packages. And Experiment5uses paired comparison method to collectreasonable location in basis of experiment4, then get the most favorite location ofconsumers. And on the basis of results, we proposed related design principle onproduction date label of packaged food.The research showed the following main conclusions:(1) The unreasonable text formatting, not quite standard of date contents andunreasonable location of the date is the main problems to consumers when they findthe date information.(2) Presented in chronological order to the text format on the packaging is the mostfavorite style to the consumers.For example "Production Date:2011/03/15";(3) The date label marked "The deadline"is more fast in performance than no label, and"production date&keeping date&The deadline" in the package is the favorite styleof the consumers. (4) There is no significant difference between vertical package and pillow package ofconsumers' choice.In other words, the type of packaging has no impact to thepreference of date labeled location.(5) The lower right of opposite side on food package is the preference position ofconsumer, and then is the lower right of right side.The results of this study are very significant for optimizing the date label andimproving related principle on production date label of packaged food in theoreticaland practical.
