A new labeling method for fruit and vegetables
Where does the tomato come from? Is the cucumber organic or not? Was the banana really fair trade - or does it just happen to be among the FairTrade fruits? Questions like these are increasingly being asked by consumers when buying groceries. In order to meet this need for information, food today has to be well labelled. Because in addition to the visual impression, the taste or the health value, other product properties are often decisive for a purchase today. Important information relates to the place of production, the variety or the cultivation method. However, conventional information carriers such as packaging, bands or adhesive labels have certain disadvantages: they have to be recycled or disposed of, and bands and adhesive labels can also be lost. For this reason, alternatives are being discussed to permanently attach important product information to the food itself.
