Miscellaneous Alcohol Oil Testing in Wine

Miscellaneous alcohol oil, also known as senior alcohol, is a general term for a class of mixtures with high boiling points, mainly including n-propanol, isobutanol, isoamyl alcohol, active amyl alcohol, etc. Miscellaneous alcohol oil in wine is generated by a series of biochemical reactions between amino acids and sugars contained in brewing raw materials during the fermentation process. Its components have their aroma and taste, and its total amount and the proportion of the content of various alcohols directly affect the liquor flavor, so the wine cannot be without miscellaneous alcohol oil.

However, its excessive content can lead to headaches and dizziness. It is slow to oxidize and decompose in the human body, and its toxicity is stronger than that of ethanol, and it tends to increase with the increase of carbon number. Proper control of the fusel oil content in liquor is crucial to the improvement of liquor quality and the health of consumers. Therefore, the content of miscellaneous alcohol oil in wine should be strictly controlled within the national standard: 60 degrees distilled liquor with miscellaneous alcohol oil content not exceeding 0.20 g/100 mL.

Solutions

In the alcohol industry, senior alcohol is often regarded as impurities. Senior alcohol is easily soluble in alcohol, and insoluble in water, similar to oil when the alcohol is low, so it is often called miscellaneous alcohol oil. Miscellaneous alcohol oil is one of the essential hygiene indicators for wine. As one of the leading providers of wine hygiene testing, Lifeasible provides professional solutions for miscellaneous alcohol oil testing in wine, including n-propanol, n-butanol, isobutanol, isoamyl alcohol, n-hexanol,β-phenylethanol, etc. Our laboratory will perform tests strictly following international standards and provide reliable analytical results.

We offer proven standard methods and other methods for miscellaneous alcohol oil testing in wine for our customers to choose from. Our solutions can meet the need for fast, simple, and accurate determination of miscellaneous alcohol oil in wine in large quantities.

• Gas Chromatography - GDX-102 Filled Column
  We use the GDX-102 filled column for the determination of alcohols in wine according to the national standard GB/T5009.48-2004. This method is accurate but has poor separation for complex samples.
• Gas Chromatography - Hydrogen Flame Ionization Detector (GC-FID)
  We offer GC-FID as a highly efficient method for detecting HABs in wine. This method can be used to improve the separation of the national standard method of spirits by optimizing the capillary column packing and chromatographic conditions and reducing the detection time to 20 min.
• Gas Chromatography - FFAP Capillary Chromatography Column
  We offer FFAP capillary chromatography columns for miscellaneous alcohol oil testing in wine with good accuracy and precision.

Our solution facilitates the development of a system for controlling miscellaneous alcohol oil in the wine production process. Our solutions for miscellaneous alcohol oil testing in wine have excellent reproducibility and accuracy for different types of wines, and the results are fully compliant with the standards. Some of our methods are easy to use, fast and efficient, with high accuracy, making them a reliable choice.
