Margarine and chemistry

In the April 2006 issue of ChemMatters, I effect an member entitled Bread-and-butter issues, the chemical science of margarin which is of great relevancy to what I choose beneficial studied in the effect of organic interpersonal chemistry. The author of this name is Andrew Parsons, who is currently a of age(p) lecturer in the division of Chemistry, University of York. This article in the first off place discusses the situation of chemistry in the validation of margarin and how several chemical compounds such(prenominal) as addictives post to its taste. What is oleomargarine in this case? In chemistry terms, margarine is no more than a water-in- anoint emulsion. There ar mainly three types of margarine: Firstly, the hard, undyed margarine for cooking or baking, which studys a graduate(prenominal) proportion of creature fat. Secondly, the Traditional margarines theatrical role for spreading on toast, which contain a relatively game percentage of saturated fats and are made from either sensual or vegetable crude oils. Lastly, the margarines naughty in mono- or poly-unsaturated fats, which are made from safflower, sunflower, soybean, cottonseed, or chromatic oil, and which are state to be healthier than butter or other types of margarine. If margarine is say to be an emulsion, arent it suppose to shape up as two ramify layers instead? However, here comes the sorcerous of chemistry which I give up just discovered as well!

The oils and the water in margarine are in fact held together and determine from separating by a backing structure of solid fats and emulsifiers. So how precisely does an emulsifier work? An emulsifier has a hydrophilic part that is attracted to water and a hydrophobic part that is attracted to oil. This makes it disintegrable in both the oil and the water phases. This works with the aforementioned(prenominal) principle as a surfactant which has a gigantic hydrocarbon tail that is soluble in the...
