Energy-Related Nutrients Testing in Wine

Alcohols all contain varying amounts of ethanol, sugar, and trace amounts of peptides and amino acids. Each gram of ethanol provides 7kcal (29.2kJ) of energy, much higher than the energy value of the same mass of carbohydrates and proteins. The energy sources of wine are small molecules such as ethanol, glucose, sucrose, maltose, dextrin, amino acids, volatile acids, and higher alcohols, which are easily absorbed and utilized by the body, so the energy provided by wine is efficient and rapid. Wine is not an essential source of energy-related nutrients such as carbohydrates, fats, and proteins, but some energy-related nutrients can be detected in wine. The calorie content of wine varies depending on the type of wine and the alcohol content, so it is essential to read labels and consume wine in moderation.

Solutions

Lifeasible offers energy-related nutrients testing in wine, including protein, fat (saturated fatty acids, unsaturated fatty acids), carbohydrates, total sugars, etc. Our labs will test to strict international standards and provide reliable analytical results. Depending on the specific energy-related nutrients you are interested in, we offer a variety of methods to detect energy-related nutrients in wine for our customers to choose from. Below is a brief description of our energy-related nutrient testing in wine.

• Protein Testing in Wine
  Protein and its compounds are one of the most important components in wine, and in wine, it is involved in the composition of the wine's sensory and physical properties, along with peptides. We offer a variety of methods for the quantitative determination of proteins, such as Kjeldahl nitrogen determination, Dumas combustion nitrogen determination, bicarbonate reaction, dye binding, forinthenol, amino acid analysis, high-performance liquid chromatography, gel electrophoresis, etc.
• Fat Testing in Wine
  We offer gas chromatography (GC), mass spectrometry (MS), and infrared spectroscopy (IR) to help determine a wide range of fat components in wine, including free fatty acids (FFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), etc. We can provide customized fat analysis services in wine according to customer requirements.
• Total Sugars Testing in Wine
  Sugars in wine are the main nutrients in fermented wines and the main source of energy in these wines, and usually influence and determine the taste of the wine. We can detect various sugars in the wine, including monosaccharides, disaccharides, and polysaccharides, using high-performance liquid chromatography (HPLC) and enzymatic assays. We specialize in the detection of glucose, maltose, and maltotriose.
