Background Lecithins are oily substances that occur naturally in plants like soybeans. Animals too are a lecithin source, example being fish.

Lecithin is, in fact, found naturally in many items used as food such as egg yolk, grains, legumes, peanuts, soybeans, wheat germ, and yeast. Lecithin as emulsifier is used in food preparation to make such food products as baked goods like cakes, chocolate, margarine, and mayonnaise because of its ability to moisturize, preserve, and emulsify.

Some natural lecithin emulsifiers like soy lecithin is used in production of instant powders too. They are natural anionic surfactants that are widely used in many food applications as emulsifiers in salad dressings and sauces, viscosity reducers and stabilizers in chocolate, anti-spattering agents in margarine, pan release agents in bakery and confectionery products and as wetting agents in instant food powders.

Use levels are small, about 0. Lecithin use is often combined with synthetic surfactants which, synergistically, allows for lesser amounts of the synthetic products. Of the estimated million pounds per year food use of surfactants in the U.

Lecithin is a major contributor to this portion of natural surfactants used in food products. Soy Lecithin or the soybean lecithin is the most popular food emulsifier and finds place in the top 10 most used ingredients in processed foods. Soy lecithin is a byproduct of soybean oil and is derived from soybeans mechanically or chemically. Soy lecithin is an excellent source of choline, which is essential to every living cell in the body and is one of the major components of cell membranes.

Without choline, cell membranes would harden thus prohibiting important nutrients from entering and leaving the cell. According to many scientific researches, lecithin and choline may even aid in memory and cognitive function, cardiovascular health, liver function, reproduction and fetal development as well as physical and athletic performance. Soy lecithin emulsifier has one more benefit and that relates to people with soy allergies. People allergic to soy can also consume soy lecithin because it is derived from soybean oil while the allergy relates to the soy protein.

It also is considered to be a surfactant, something that is a common term found when purchasing household cleaners. Surfactants allow liquids to spread out and become absorbed more quickly by breaking surface tension which is why soy lecithin is used in many prepackaged cake batters.

It also has an anti-foaming property, which is helpful in keeping those same cooking sprays coming out more oily than foamy. Statement of the Problem Lecithin was ubiquitous in the processed food supply. It was most commonly used as an emulsifier to keep water and fats from separating in foods such as margarine, peanut butter, chocolate candies, ice cream, coffee creamers and infant formulas.

Lecithin also helps prevent product spoilage, extending shelf life in the marketplace. Food processing industries are increased day to day in the country. It indicates that the amount of lecithin demand was also increased. Up to now the country demand was fulfill through import from England, China and India..

The proposed solution for this was producing lecithin domestically using the available raw material. Soy bean was the better lecithin content from other raw materials. Therefore; in this paper production of soy lecithin from soy oil sludge was discussed briefly. Objective The general objective of this project was utilization of soy oil sludge for lecithin production.

Outcome of the project Hence; it was new in this country it gives a lot of important benefits in the economical aspect. Lecithin is the gummy material contained in crude vegetable oils and removed by degumming. Soybeans are by far the most important source of commercial lecithin and lecithin is the most important by-product of the soy oil processing industry because of its many applications in foods and industrial products.

The three main phosphatides in this complex mixture called "commercial soy lecithin" are phosphatidyl choline also called "pure" or "chemical" lecithin to distinguish it from the natural mixture , phosphatidyl ethanolamine popularly called "cephalin" , and phosphatidylinositols also called inositol phosphatides.

Indeed lecithin is one of the most complex and versatile substances derived from the soybean. The word "lecithin" is derived from the Greek term lekithosmeaning "egg yolk. In the late s it was also spelled "lecithine" in English, a spelling that is still used conveniently in German to refer to the pure or chemical lecithin. In present-day English, the term "lecithin" has two different meanings, which can be confusing. To most food processors and chemists it refers to the natural complex mixture of phosphatides, but to most regular chemists, biochemists, and pharmacists it is a trivial term for the chemically pure phosphatide, phosphatidyl choline.

In this chapter we will consistently use the term "lecithin" in its broader sense, to refer to the natural complex. The commercial term "soybean phosphatides" may be used to denote the oil-free lecithin complex. Lecithin is obtained in the process of degumming crude soy oil, usually at the refinery of the company making commercial lecithin rather than at the oil mill.

Crude soy oil contains an average of 1. The emulsion is then agitated or stirred for minutes as the phosphatides hydrate and agglomerate, forming a heavy oil-insoluble sludge, which is separated from the oil by use of a centrifuge. Fluidizing additives such as soy oil, fatty acids, or calcium chloride can then be added to reduce the viscosity to that of honey and prevent the end product, on cooling, from being a highly plastic solid.

The oil in unrefined lecithin can be removed by extraction with acetone phosphatides are insoluble in acetone to give a dry granular product called "refined lecithin.

Even more specifically, this section describes the recovery of lecithin from soybean icing, the opiate residue during the process of obtaining soy protein concentrate CSPC. After two years of research it was discovered that this gum was a mixture, of tosidia pidios, which was the main source for the production of solecium lecithin.

A novel approach to process crude oil membrane concentrate using a centrifuge

The present work discusses an alternative process to handle crude oil membrane concentrate during a degumming process. The main advantages of this method are limited oil loss, potential lecithin by-product, and a supposedly simpler process. In this work, we first show that the phase behavior of an oil-PL-hexane system can be exploited to identify the various steps of the process. The steps include membrane degumming, hexane evaporation, and centrifugation.

This invention relates to improved methods for treating phosphatide-containing mixtures. More particularly, this invention relates to methods for recovering purified vegetable oil, aqueous organic acid, and organic acid-treated phosphatide from a phosphatide-containing mixture comprising an acid-and-oil mixture obtained from organic acid refining of vegetable oil. Vegetable oils are typically obtained by pressing or extracting the oil seeds of plants such as corn or soybeans. Properly processed vegetable oils are suitable for use in many edible oil and fat compositions destined for human consumption. Such edible oils and fats include salad oils, cooking oils, frying fats, baking shortenings, and margerines. In addition to being widely used in edible oils and fats, vegetable oils are also increasingly utilized in important industrial products such as caulking compounds, disinfectants, fungicides, printing inks, and plasticizers.

In pharmaceutical formulations, phospholipids obtained from plant or animal sources and synthetic phospholipids are used. Natural phospholipids are purified from, e. Because of the use of validated purification procedures and sourcing of raw materials with consistent quality, the resulting products differing in phosphatidylcholine content possess an excellent batch to batch reproducibility with respect to phospholipid and fatty acid composition. Synthetic phospholipids with specific polar head group, fatty acid composition can be manufactured using various synthesis routes. Synthetic phospholipids with the natural stereochemical configuration are preferably synthesized from glycerophosphocholine GPC , which is obtained from natural phospholipids, using acylation and enzyme catalyzed reactions. Synthetic phospholipids play compared to natural phospholipid including hydrogenated phospholipids , as derived from the number of drug products containing synthetic phospholipids, a minor role. Only in a few pharmaceutical products synthetic phospholipids are used. Natural phospholipids are used in oral, dermal, and parenteral products including liposomes.
