Lies on labels, or cases of misleading consumers on the example of vegetable oils

In 2018, the Polish Trade Inspection in the whole country carried out an assessment of unrefined vegetable oils and olive oils of various categories. First of all, the correctness of marking, physicochemical parameters, storage conditions, traceability of products and their dates of minimum durability were assessed. In total 380 batches of products were inspected. Results of the examination show that producers cheat consumers by providing, for example, untrue nutritional values or false information about dietetic or health traits. The purpose of this article is to determine what consumers should know to verify the correctness of information on product labels independently. The theoretical part of the article was based on the EU regulations analysis regarding vegetable oils properties, including the characteristics of olive oil. The empirical part concerned data from Polish Trade Inspection reports, as well as statistical data on production and sale of oil and olive oil from the portal Statista. In this article methods of documentary research and comparative analysis were used. For the main conclusion it can be assumed that products of poor quality or incorrect labeling can be found in each product category; therefore, consumers should pay attention to such elements as information in their native language, a full list of ingredients, or correct indication of nutritional values.
