Overview of communication activities and a plan to improve public perception of food additives
Ana Starman, Elizabeta Mičović, Tomaž Langerholc, 2023, izvirni znanstveni članek

Opis: Food additives are considered a high-risk factor by the EU and Slovenian consumers, although they are strictly regulated by the authorities and pose a low risk to consumers. However, risk communication about food additives is challenging and involves the interactive exchange of information about hazards, taking into account the risk perception of the target groups. A plan for communication activities aimed at improving public perception of food additives was structured based on the review of scientific literature and the overview of previous communication efforts communicated by various information sources to raise awareness among the Slovenian public from January 2015 to January 2022. The overview included governmental and nongovernmental organizations that are credible sources of information on food safety for Slovenian consumers at the national and EU level. The objective was to develop an effective communication plan on food additives with defined objectives, target groups, key communication messages, communication activities, tools, and channels. The proposed plan can serve as a good basis for launching an effective awareness campaign on food additives to reduce public concern and improve the knowledge of average consumers about the use of additives in food.

Isolation and concentration of natural antioxidants with high-pressure extraction
Majda Hadolin Kolar, Andreja Rižner Hraš, Davorin Bauman, Željko Knez, 2004, izvirni znanstveni članek

Opis: In present work, the purification of crude rosemary extract with supercritical fluids is presented. Carbon dioxide was used as a solvent. The crude extract was prepared from rosemary with conventional extraction process. The supercritical CO2 extraction of crude extracts was performed at pressures 10 and 20 MPa and temperatures 35 and 60 °C. The best results were obtained at pressure 10 MPa and temperature 35 °C. The content of carnosic acid in the samples before and after high pressure extraction was identified by high performance liquid chromatography. The content of carnosic acid in purified extract is higher compared to crude extract. The antioxidative efficiency of extracts was determined by measuring peroxide value. Activity ofpurified rosemary extracts is higher compared to crude extracts.
Ključne besede: chemical processing, high pressure technology, extraction, CO2, natural antioxidants, rosemary extract, food additives
