Impact of wine manufacturing practice on the occurrence of fining agents with allergenic potential.

Proteinogenic wine fining agents are hidden allergens and could present a risk for consumers with allergies. Therefore, the European Parliament adopted Directive 2003/89/EC amending Directive 2000/13/EC to declare ingredients, contaminations and processing aids that are known to trigger allergic reactions. The Amendment Regulation (EU) 1266/2010 excluded the labelling of wines which are processed with hen's egg and products thereof until 30 June 2012 to get more scientific findings.

Development of a sensitive ELISA for the detection of casein-containing fining agents in red and white wines.

Fining of wine with proteinogenic fining agents such as casein from cow's milk is a traditional and commonly used technique all over the world. Casein and other proteins from cow's milk are well-known food allergens, which pose a risk for allergic consumers. Temporary regulations exempting the labeling of milk and products thereof in wine expired.

Evaluation of the efficiency of enological procedures on lysozyme depletion in wine by an indirect ELISA method.

Potential residues of the potent allergen lysozyme used as a microbial stabilizing agent in wine production might pose a serious health thread to susceptible individuals. Therefore, EU legislation requires the labeling of the allergenic agent, if it is present in the final product. To allow for product testing, an indirect ELISA method to be specifically used in wine analysis was developed and validated.
