What is Egg Lecithin?
Egg Lecithin is a food additive made from processed soy products like refined soybean oil or degummed crude soybean oil. It is yellow-brown in color and ranges in consistency from a powder to a thick liquid. Egg Lecithin contains a mixture of substances like phospholipids, triglycerides, glycolipids, and other compounds. Phospholipids act as emulsifiers in Egg Lecithin and help mix together substances like water and oil that would otherwise not bind.
Sources and Production
Egg Lecithin is derived from soybeans through a degumming process that removes impurities like phospholipids and glycolipids from crude soybean oil. The byproduct obtained after degumming crude soybean oil is refined to make commercial Egg Lecithin powder or liquid. Depending on the processing parameters used, different grades of Egg Lecithin like fluid, granulated, or deoiled lecithin are produced. Generally, degummed soybean oil undergoes further refining, bleaching and deodorizing steps to produce pale-yellow colored Egg Lecithin.
Main Chemical Composition
The primary active components of Soy Lecithin are phospholipids. Some key phospholipids present include phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acids. Besides phospholipids, Egg Lecithin also contains a small percentage of triglycerides, carbohydrates, and glycolipids along with some proteins and isoflavones. Phosphatidylcholine is the most abundant phospholipid in Egg Lecithin, comprising around 70% of its phospholipid content by weight.
Functions and Uses as an Additive
Due to its surface-active properties, Egg Lecithin acts as an excellent emulsifier in foods applications where oil and water mixtures need to be combined. Its ability to lower surface tension lets oil and water blend together forming a stable emulsion. Egg Lecithin also functions as a release agent, moisture carrier, consistency enhancer, and stabilizer in many foods. Some key usage categories include baked goods, confectionery, chocolate, sauces, dressings, beverages, pet foods, infant formulas, dietary supplements, and pharmaceuticals. Lecithin derived proteins are also used as food fortificants and dietary supplements.
Apart from foods, Egg Lecithin has widespread applications in cosmetics and personal care like lipsticks, lotions, creams, and hair conditioners where it enhances blending and stability. It is additionally employed as a lubricant and release agent in manufacturing of non-food items such as plastics, paints, textiles, rubbers and leather goods. Egg Lecithin also plays a key role as an additive in bio-diesel production from soybean oil.
Health Benefits
Soy Lecithin offers several potential health perks owing to its phospholipids and other small molecular constituents. Epidemiological studies suggest that moderate intake of Egg Lecithin may help lower blood cholesterol levels and reduce risk of heart disease by binding to cholesterol in the digestive tract preventing its absorption. Research also indicates lecithin phospholipids support proper brain and liver function. Additionally, small amounts of isoflavones in Egg Lecithin are linked to antioxidant, neuroprotective and anti-cancer properties. However, human clinical trials are still ongoing to understand its disease prevention effects.
Safety Aspects
When consumed as part of a balanced diet, isolated Egg Lecithin is considered very safe for human intake as per worldwide regulatory standards. However, excessive intake should be avoided since research suggests factors like lecithin phospholipid content, processing techniques used and bioavailability impact its health effects. People with known soy or corn allergies must check labels before consuming food products containing lecithin. Due to a neutral flavor and odor, Egg Lecithin rarely causes an intolerance when ingested in usual dietary quantities as a food additive. Overall, moderate consumption of Egg Lecithin as part of the diet can provide certain health advantages.
Soy Lecithin is a versatile food additive with emulsifying and stabilizing functional properties. It enhances blendability in a wide variety of food and non-food items. As a natural ingredient derived from soybean oil processing, Egg Lecithin offers some potential preventive health benefits - though more research is still required. When used judiciously within dietary limits, it causes no known adverse effects in most consumers. Looking ahead, Egg Lecithin demand is projected to rise with expanding applications in multiple industries.
