The Importance of Choline Analysis – joking aside!

What’s yellow and dangerous? ........ Shark infested custard! Or how about What’s yellow, vital for human development from foetus to adulthood, and contains choline, fatty acids, phosphoric acid, glycerol, triglycerides, glycolipids, and phospholipids .... Answer, Lecithin. Or, what Biochemistry Analyser will give accurate results in under one minute? ....The New YSI 2900 Series Analyser, of course!

OK, two of the three above are not jokes, but are important facts. Lecithin is a fascinating mixture of the above mentioned compounds that has had a very distinct identity since its isolation by the French chemist Theodore Gobley in 1846. It has both lubricant and emulsification properties and can function as a surfactant, lowering a liquid’s surface tension. Lecithin is often described as nature’s emulsifier as its detergent like properties prevent cholesterol and other fat from sticking and forming blood clots.  The continued recognition of a distinct commodity called ‘Lecithin’ is partly down to its importance as a health supplement and in food manufacturing. 

Choline is the principal ingredient of Lecithin, and is a rather unsung hero of the human diet, a water-soluble essential nutrient frequently considered alongside the B vitamins. It is the crucial precursor of the neurotransmitter acetylcholine and it is a component of two of the most common membrane phospholipids.  Choline can be found naturally in many foods, especially eggs, and it is often used as a food additive in dairy, confectionery and baked products as an emulsifier to give even blending, reduced hardening and improved texture. 

However, it is thought that large sections of the population might be suffering from a choline deficiency and Supplements are potentially vital for many vulnerable groups such as sick young children, and post-menopausal women, and it also has a role in infant formula milk and health recovery preparations.

As with other similar ‘food-stuffs’ it is crucial that concentrations remain constant and known. In order to ensure the required level of accuracy of Choline measurement, informed manufacturers are turning to a YSI Biochemistry Analyser, such as the recently launched YSI 2900 Series. This versatile, modular, instrument uses proprietary immobilised enzyme technology to deliver precise analysis results for Choline, in less than a minute, employing highly flexible sampling procedures, including 96 well plates.

Of course the 2900 Series is not restricted to measuring Choline! Glucose, Sucrose, Galactose, Lactose, Xylose, Lactate, Glutamine, Glutamate, Ethanol, Methanol, Glycerol, Hydrogen Peroxide, are all frequently chosen alternatives, as well as ISE measurement of Ammonium and Potassium.  The analyser can be configured with up to 3 sensor modules, making it capable of measuring up to 6 chemistries.

This makes the YSI 2900 Series of Biochemistry Analysers the ideal choice for many different industries in addition to Food & Beverage Processing.  Biofuel Production, Bioprocess Monitoring and Fermentation Control have all gained by employing this speedy and versatile analyser.

We should also mention that the YSI 2900 Series is very simple to use with onboard training videos, has flexible connectivity, integrated autosampler and anti-clogging mechanisms .....and we are not joking!
