Cyanide Testing in Wine

Cyanides are a class of highly toxic compounds with cyano (CN-), mainly referring to cyanates and hydrocyanic acid. They can enter the body through the respiratory and digestive tracts and the skin. Cyanide in wine is mainly produced by the hydrolysis of cyanogenic glycosides ligands in raw materials (such as cassava, substitutes, beans, and other fruit kernels or mixed with some wild plants) during the fermentation process. From a toxicological point of view, cyanide is an irreversible inhibitor of cytochrome C oxidase, which inhibits cellular respiration and is thus considered a highly toxic compound that is a serious food safety hazard. Because of its extreme toxicity, cyanide requires to be detected at low mass concentrations (ng/mL).

Solutions

Cyanide is a toxic substance, and tiny amounts can cause poisoning or even death in humans or animals. Therefore, cyanide is a significant safety indicator for wine. As one of the world's leading providers of wine hygiene testing services, Lifeasible offers professional cyanide testing solutions for wine, including sodium cyanide (NaCN), potassium cyanide (KCN), and hydrocyanic acid (HCN). Our laboratory will perform tests strictly following international standards and provide reliable analytical results.

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

• Spectrophotometric method
  We offer a spectrophotometric method for the standard determination of cyanide in wine, such as the most classic spectrophotometric method for detecting isonicotinic acid-pyrazolone. This method has strict pH requirements for the sample to be measured, is tedious and time-consuming to perform, and is unsuitable for analyzing large batches of samples.
• Silver nitrate titration method
• Fluorescence method
• Atomic absorption method
• Gas chromatography method
• Gas chromatography-mass spectrometry (GC-MS) method
  We can detect cyanide in wine by gas chromatography with an ECD detector by direct headspace injection after the derivatization of cyanide with chloramine to cyanogen chloride. In this method, the sample does not need to be distilled, and the operation is easy and fast with few interferences, which is practical.
• Ion chromatography with pulsed amperometric detection
  We have developed an ion chromatography-pulsed amperometric detection method for rapidly and accurately determining cyanide in prepared wines. This method can accurately determine low levels of cyanide in the presence of high concentrations of interfering substances with a wide linear range, good linearity, low detection limit, good precision, and high accuracy.

Our solutions for cyanide testing in wine have excellent reproducibility and accuracy for different types of wines, and the results fully comply with the standards. We aim to meet the requirements for rapid detection of cyanide in various wines. Some of our methods are easy to use, fast and efficient, with high accuracy, making them a reliable choice.
