Soya Bean Lecithin as a Healthy Alternative
A Natural Emulsifier
Lecithin is a natural emulsifier. It is suitable for use in food as well as in industrial chemicals, paints, animal feedstuffs and pharmaceuticals. It is especially suited for use in food because of its unique functional and nutritional properties. Lecithin is a naturally occurring complex mixture of phospholipids which are similar to phospholipids found in living animal and vegetable cells. Lecithin is sourced from soya bean, corn, cottonseed, peanut, and sunflower. Soya bean has a lecithin content of 0.5 percent which is the most abundant source.
Amongst all natural emulsifiers, lecithin is unique for the sheer diversity of functions it can perform in the food industry, namely:
- It acts as a release agent reducing friction between cooked food and hot surfaces.
- It acts as a viscosity agent coating food particles thus again reducing friction.
- As an emulsifier it stabilizes oil-in-water and water-in-oil emulsions
- As a dispenser it improves the uniformity of fat distribution
- it acts as a wetting agent rapidly dispersing powders in aqueous systems
- A blending aids that aid in reducing mixing time of incompatible ingredients like non-polar fat and polar sugar.
Soya Beans
Effective Alternative to Saturated Fatty Acids
Lecithin has an important function in the formation and development of reduced calorie and low fat foods for the health conscious consumer - one of the most dynamic markets.
As food makers strive to reduce levels of calories, cholesterol and greasiness in food, lecithin should be used as a healthier but effective alternative to saturated fatty acids to perform the role of release agents.
Soya bean is readily available in most countries. To extract lecithin from Soya beans oil, you use a process known as degumming which involves heating the Soya bean oil, adding water, agitating and finally separating the lecithin by centrifusion
Superior Qualities
But what really makes lecithin have such superior qualities? This is due to its amphiphilic chemical composition. The surface active phospholic molecules which are main constituents of lecithin have both hydropholic water repellent and a hydrophilic water attracting parts. Because of this, lecithin is capable of emulsifying chemically incompatible ingredients like low polarity bakery shortenings and high polarity sugars. Lecithin is therefore capable of stabilizing both oil-in-water and water-in-oil emulsions.
And since lecithin is derived from natural sources like soya beans, lecithin should be ideal to health food makers where non-chemical ingredients are crucial. By using lecithin in preparation of health food, your foods will conform well to the non-chemical consumer trends throughout the planet earth.

Lecithin has an important role of replacing the original emulsifier which is the egg York thus significantly reducing cholesterol levels in food.
