Project description:

For the purposes of the National Research Program "Nutrition and Public Health", the Nutrition Institute started establishing the CLAS (Composition and Labelling Information System) program in 2015, in which data on pre-packaged foods on the market in Slovenia are collected. It is an upgrade to the project for the collection of food labelling information from 2011, which was supported by the Slovenian Research Agency (ARRS) and the Ministry of Agriculture, Forestry and Food (MAFF) [V7-1107: Nutrition and health claims on foods; 1.10.2011-30.9.2013]. The project involved collecting data on the nutritional value of foods and the use of symbols, nutrition and health claims. In this way, data on the availability of foodstuffs on the market in 2011 were collected and used for various research (eg Pravst et al. 2015, Korošec et al. 2014).

With the implementation of a new research on the availability of pre-packaged foods in Slovenia (data collection carried out in 2015), the Nutrition Institute has begun with the upgrade of the software. A database and the CLAS - Composition and Labelling Information System application were created, which enables the collection of photographs of food labelling, their evaluation using OCR technology and the processing of food composition and labelling data. After the test period of use, the new software tool was put into regular use in 2016 and was also used for the food data collection in 2017. The following data on prepacked foods is collected within CLAS:

  • photographs of food labelling;
  • data on the nutritional value of the foods;
  • data on ingredients, including data on the use of additives, vitamins and minerals;
  • data on allergens;
  • data on symbols, nutrition and health claims.
