Choline Analysis Using The YSI Analyser

One of the many applications on the YSI Analyser is for testing choline levels via choline analysis. In fact, one YSI customer relies entirely on a YSI Analyser in order to measure the levels present in the infant formula they manufacture. Given the critical nature of these tests, it's vital for the analyzers to give extremely accurate readings.

While choline is considered to be a chemical very similar to the range of B-vitamins, it hasn't officially been recognized as a B-vitamin. Furthermore, there is still an ongoing debate with regards to the way in which choline reacts with other nutrients, although studies have proven that vital for human development from foetus to adulthood. Scientists have also determined that while the human body can produce some choline, dietary choline is also necessary, particularly in the case of infants because of their rapid rate of development.

Nutritional researchers first became interested in choline analysis when it was discovered that rats experienced inadequate brain development if their mothers never got enough of it during their pregnancies. It was also noted that it is linked to memory development, and this in turn lead to research which now suggests that apart from brain development, choline may have the potential to help prevent memory loss in the elderly.

It is also currently being used in some treatments for Alzheimer's disease. Research has also shown that choline is beneficial to the liver, and that it can effectively lower cholesterol and homocysteine levels.

The vast majority of foods contain small amounts of choline, but the best food sources include beef, chicken, eggs, spinach and cauliflower. Interestingly enough, a single large egg contains approximately 112 mg of choline, hence the reason why egg yolks are often used to make lecithin, which is a choline supplement.

As a general rule of thumb, infants between 0 to 6 months require an average daily intake of 125 mg. Children between the ages of 1 to 3 years require an average of 200 mg, while adult men and women require 550 mg and 425 mg respectively. Pregnant women and nursing mothers require more than the average in order to minimize the risk of neural tube defects in the baby.

As is to be expected, breast milk contains high levels of choline, which in turn has led to the Food and Drug Administration (FDA) requiring these levels to be replicated in infant milk formula which has not been made from cows' milk.

YSI's 'infant milk' customer has already been using their YSI Analyser for several years to carry out choline analysis in their products, so that they meet FDA requirements. Most manufacturers tend to stick with the YSI Analyser, not only because of its impressive accuracy, but also because the device is incredibly user-friendly.
