Vitamins Testing in Wine

Vitamins are defined as organic compounds that, unlike fats, carbohydrates, and proteins, are trace substances essential for normal physiological function and cannot be synthesized endogenously by the organism itself. In the winemaking process, vitamins are involved in many yeast metabolic pathways, including amino acids, fatty acids, and alcohols. Studies have found that vitamin deficiencies can slow fermentation and impair growth and fermentation rates. This suggests the importance of vitamins in the fermentation process and developing aromatic compounds in wine. In the last decades, all experiments to determine the vitamin content in wine have been performed with analytical methods of low sensitivity, and their proper ranges were not determined in wine samples. Moreover, the wide diversity of vitamins complicates their analysis in wine samples and therefore requires developing cutting-edge techniques to assess different aspects of vitamins in an oenological context.

Solutions

Vitamins are compounds of great importance in yeast metabolism and their impact on winemaking. Lifeasible offers professional solutions for vitamin testing to analyze over 13 vitamins in wine, including water-soluble and fat-soluble vitamins. Our laboratories will perform tests according to strict international standards and provide reliable analytical results.

Our technical team has developed an extraction procedure to assess the total vitamin content in wine that releases the bound form of the vitamin, which facilitates forward analysis and quantification. Our extraction methods are usually designed for each vitamin to ensure their stability, and there are also procedures suitable for the simultaneous extraction of several vitamins.

Below are our analytical methods for determining vitamin content in wine samples. These methods allow for faster, more accurate, and sensitive quantification of vitamins in wine.

Lifeasible offers professional vitamin testing solutions to analyze the vitamin content in wine, from microbiological to chemical analysis, either asynchronously for the determination of different vitamins or simultaneously. Our international level of testing has earned us the trust of many clients. If you are interested in our solutions, please contact us for a technical consultation and quotation.
