What is soy lecithin

Lecithin is a lipid that is produced in the liver, but there are situations in which its production is insufficient.

This nutrient is used in our body by the circulatory and nervous systems , and is of vital importance for the body, as it constitutes the cell membrane, which contributes to the formation of organic tissues. To supply lecithin in the body or compensate for its lack, it is possible to consume this fat through foods such as soy and derivatives or supplementation of this substance.

Lecithin is usually extracted from soybeans and is basically a fat obtained through the grain of the plant, during the process of extracting soybean oil.

This vegetable fat has several properties, benefits and uses. And that is what will be seen in the next topics.

Uses of soy lecithin

Soy lecithin has several uses, in addition to being used as a nutritional supplement, an ingredient in cosmetic products, it also serves as a vegetable emulsifier in the culinary and food industry, as it gives a better mixture to the ingredients (flours, sugars, oils, yeast, etc.) ensuring uniformity and elasticity to the dough, making the processing of these products more practical.

Because of its property , soy lecithin is used as an egg substitute in vegan recipes. Each tablespoon of soy lecithin (emulsion) replaces 1 egg in the recipe, or you can also use 1 to 2% lecithin according to the weight of the flour used in the recipe. This product is well used in breads, vegetable margarines, chocolates, cakes, pies, fillings, cookies, cookies, ice cream, creams, etc.

In cooking , soy lecithin can be used in several ways, such as:

  • Emulsifier(mixing water with oil) in bread, cakes, pies, fillings, pasta recipes in general.
  • In the sauce, a teaspoon of powdered soy lecithin is able to unite the particles, making it more full-bodied.
  • Egg substitutein recipes for cake, biscuits and breads.
  • Powdered lecithin can be used over salads.
  • To incorporate fruit juices, just add a small spoonful of powdered lecithin, the fruit juice broth thickens in just two minutes. This is due to the emulsifying power of lecithin that joins the pieces of the beaten fruit to the added water portion.
