Yes, there are correlations between biogenic amine levels and the use of fining agents in winemaking. Biogenic amines are organic compounds that are naturally present in various foods and beverages, including wine. They are formed during fermentation and can also be produced by microbial activity. Some biogenic amines, such as histamine, tyramine, and putrescine, are known to cause adverse reactions in sensitive individuals when consumed in high amounts.
Biogenic Amines in Wine
Biogenic amines can be found in wine due to the fermentation process, as well as the presence of certain bacteria and yeasts. The levels of biogenic amines in wine can vary depending on several factors, including grape variety, winemaking practices, storage conditions, and the presence of spoilage microorganisms.
Role of Fining Agents
Fining agents are substances used in winemaking to clarify and stabilize the wine by removing unwanted particles and compounds. Common fining agents include bentonite, gelatin, egg whites, and activated carbon. While fining agents can help improve the appearance and quality of the wine, they can also potentially affect the levels of biogenic amines present in the final product.
Correlations Between Biogenic Amine Levels and Fining Agents
Several studies have examined the impact of fining agents on biogenic amine levels in wine. Some key findings include:
- One study found that the use of certain fining agents, such as bentonite and activated carbon, can reduce the levels of biogenic amines in wine by adsorbing them onto the fining agent particles.
- Another study suggested that the addition of fining agents during winemaking can lead to a decrease in biogenic amine concentrations, particularly histamine and tyramine.
- However, it is important to note that the effectiveness of fining agents in reducing biogenic amine levels may vary depending on the type of fining agent used, as well as other winemaking factors.
Factors Influencing Biogenic Amine Levels in Wine
Several factors can influence the levels of biogenic amines in wine, including:
- Grape variety: Different grape varieties may have varying levels of precursor compounds that can lead to the formation of biogenic amines during fermentation.
- Microbial activity: The presence of certain bacteria and yeasts during fermentation can contribute to the production of biogenic amines in wine.
- Winemaking practices: Factors such as fermentation temperature, pH levels, and aging conditions can also affect the formation of biogenic amines in wine.
Regulatory Considerations
Regulatory agencies, such as the European Union, have established limits on the maximum levels of biogenic amines allowed in wine to ensure consumer safety. Exceeding these limits can lead to health risks for sensitive individuals, including headaches, hypertension, and allergic reactions.
