What is Soy Lecithin? How Is Soy Lecithin Made?

In this video, I discuss Soy Lecithin, which is an ingredient found in a wide variety of foods. We also cover what is soy lecithin and how is soy lecithin made. Transcript (partial) What is soy lecithin? Actually the first question is what is lecithin? It is a mixture of phospholipids in oil. Great, what is a phospholipid? Essentially a phospholipid is a fat molecule that is able to dissolve into mixtures that contain both oil and water. So, we are going to look at how a phospholipid is able to bind water and oil together. We are going to go thru this in a very general sense. First lets look a little deeper into a fat molecule. We start with a glycerol group, which acts like the backbone of the molecule. Attached to it, is a phosphate group. And in lecithin, there is a choline group attached to the phosphate group. Lastly, we have 2 fatty acid chains that are attached to the glycerol group. Now lets take a water drop, and an oil drop. Normally, they wont bind. However, When we throw our phos in, the phosphate group binds to the water drop, and the fatty acids bind to the oil drop. The basic molecular structure of a phospholipid consists of tails made of 2 fatty acid chains, and a head that contains a glycerol, phosphate, and choline group which is water soluble. In a mixture that contains both oil and water, the phosphate group will attach to the water, and the tails to the oil. This is what allows oil droplets to stay in water for a long time. This process is known as emulsification, and lecithin is known as a great emulsifier in many processed foods. You will see it regularly in chocolate bars. So, now that we know what lecithin is, we can tackle the soy part. I have a separate video posted where I discuss soy in depth. I will put a link to that video on the screen, and in the description box below. Basically, Soybeans are processed to separate oil and protein contained in them. Once that is completed, lecithin is then removed from the oil. Soy lecithin has some health benefits. It is high in choline, which is essential to cells, with out it, cell membranes would harden. Choline is also vital for healthy liver function, and its now being sold as a dietary supplement. But, its main benefit is to the food industry. As I said earlier, it emulsifies and stabilizes food, which gives it……longer shelf life. It is also found in cooking sprays, as it reduces stickiness. Now, for the bad…90% of soy in America is gmo, and it goes through processing that exposes it to chemicals. Bottom line…Soy lecithin has some health benefits, but, if possible, you want to stay away from the gmo, and any that has been exposed to chemicals.
