Wine is one of the few foods that are not subject to mandatory nutrition labeling, except alcohol content. Therefore, health-related characteristics can be inferred from attributes related to production methods and alcohol content. The attitude of health-conscious and health-oriented consumers and those with above-average nutritional knowledge toward these labels, usually depends on several factors, including wine involvement, health awareness, and interest in nutritional information. Grape pomace is rich in dietary fiber, and large amounts of this fiber may enter the wine during the winemaking process; however, the food composition list indicates that wines contain zero dietary fiber.
Hard-to-digest polysaccharides are the main component of dietary fiber. Polysaccharides in wine are usually studied based on organoleptic properties, but nutritional methods also apply to this wine component. Lifeasible offers professional health-related nutrient testing solutions in wine to measure the amount of fiber present in wine, including water-soluble dietary fiber and insoluble dietary fiber.
Our labs will perform tests according to strict international standards and provide reliable analytical results. We offer various methods for determining dietary fiber in wine, including gravimetric analysis, enzymatic gravimetric analysis, and high-performance liquid chromatography (HPLC).
Our technical team develops one-stop solutions for analyzing dietary fiber amounts in wine, from wine concentration, enzyme treatment, and dialysis, to dietary fiber determination. We can determine dietary fiber in wine, including:
(1) Obtain a representative sample of the wine to be tested.
(2) Extract the fiber from the wine using a chemical solution.
(3) Separate the soluble and insoluble fiber fractions using filtration and centrifugation.
(4) Weigh and measure the soluble and insoluble fiber fractions separately.
(5) Calculate the total dietary fiber content by adding soluble and insoluble fiber amounts.
(6) The results are recorded, and the total dietary fiber content is reported.
Lifeasible offers professional dietary fiber testing solutions to analyze soluble and insoluble dietary fiber in wine. Our international level of testing has earned us the trust of many customers. If you are interested in our solutions, please contact us for a technical consultation and quotation.
