What Is a Soy Lecithin Allergy?

Soy lecithin (Lecithin High Potency, also known as soy yolk) is a by-product in the process of refining soybean oil. It is obtained by solvent extraction, centrifugation and alcohol washing. The granular soybean lecithin on the market is a product of phospholipids precipitated during the degumming of soybean oil, and then processed and dried. Pure soy lecithin is a brown-yellow waxy solid, which easily absorbs water and turns into a brown-black gel; easy to oxidize, and gradually turns from brown-yellow to brown-black; soy lecithin contains lecithin, brain phospholipid, etc., with Delay aging and prevent cardiovascular and cerebrovascular diseases. Soy lecithin can enhance the cell's ability to transmit information, thereby increasing the vitality of the brain and the ability of the cell membrane to repair itself to protect the liver.

Phospholipids are a kind of pure natural nutritional health food, which comes from a wide range of sources, mainly in the cells of animals and plants, and are the main components of biological cell membranes. Animals are rich in heart, liver, brain, kidney, bone marrow and eggs. ; The content of oil crop seeds in plants is relatively concentrated, for example, the content of peanut kernel phospholipids is 0.4 to 0.63%.

Soy lecithin is a basic substance of life. It is not only an important part of human biofilm, but also

Pure products such as lecithin and cerebrolipid are white waxy solids that crystallize at low temperatures. Because the phospholipid molecule contains a large amount of unsaturated fatty acids, it is easily oxidized by oxygen in the air. After being left in the air for a period of time, it forms a polymer of peroxides. The color of the phospholipid changes from white to yellow-brown, and it becomes brown-black over time. .

The color of soybean phospholipids mainly comes from two parts: one part is brought in by soybean raw materials, like

Lecithin is usually extracted from soybeans by solvent extraction and centrifugation followed by alcohol washing.

1. How to identify good quality lecithin

Two characteristics of lecithin

Not resistant to high temperature, the temperature is above 50 , the activity will gradually be destroyed and disappear in a certain period of time. So take

When choosing soy lecithin products, you should refer to the following three criteria:

1. Choose Lecithin with high concentration: Soy lecithin products in the market are mainly capsules and granules, and capsules are the main ones. The capsule concentration is low, the lecithin content is about 60%, and the main active ingredient phosphatidylcholine (PC) content is about 15.7%. The particle concentration is high, the content of lecithin is low at about 97%, and the content of the main active ingredient, phosphatidylcholine (PC), is about 24%. The concentration of soy lecithin particles is 1.617 times that of soft capsules. The price of 100 grams of soy lecithin soft capsules commonly on the market is about 80 yuan, and the price of 225 grams of soy lecithin granules is about 100 yuan. After calculation, if the same content of lecithin, the price of soft capsules is higher. Particles 2.906 times. So in terms of cost performance, soy lecithin is much better than soft capsules.

2. Choosing lecithin granules: Hyperlipidemia is a chronic disease, and you need to take products that control lipids for a long time. If the product has side effects or contains harmful substances, it will accumulate and enlarge in the body. Soy lecithin soft capsules contain 25% -35% of soybean oil. At the same time, food additives such as gelatin and glycerin are added to make the shape of the capsule and maintain fluidity. The soybean oil in the granules contains less than 3%, soybean oil and glycerin. The intake of these oils may increase the body's already heavy oil load in hyperlipidemic populations. Therefore, particles are generally better than soft capsules in terms of safety.

By comparing the concentration and safety, we can see that soy lecithin particles are better than soft capsules, but not all soy lecithin particles can be purchased with confidence!

3. Choosing soy lecithin granules without residues and additives: Today, food safety is becoming increasingly severe, and food additives, organic solvents and heavy metal residues are increasingly threatening our lives, so we need to look at the third point-whether there are residues ,Add to.
