What age is lecithin suitable for?

What age group is suitable for eating lecithin is also the primary concern of everyone. For teenagers, will it stimulate the release of growth hormones and lead to related diseases? For the elderly, will it increase the occurrence and development of geriatric diseases such as senile hypertension and dementia? Although this is an important nutrient in the body, different age groups have different needs for it. Choose according to the situation.

Lecithin, also known as egg yolk, is known as the "third nutrient" alongside protein and vitamins.

Lecithin is suitable for people:

1. The U.S. Food and Drug Administration (FDA) stipulates that phospholipids must be added to infant formula.

2. Students, intellectuals and middle-aged and elderly people: Lecithin can enhance brain vitality, eliminate brain fatigue, enhance memory and improve learning and work efficiency. It can also repair damaged brain cells and prevent the occurrence of Alzheimer's disease.

3. Patients with long-term drinking, overnutrition and fatty liver: Take 10-15 grams of lecithin daily. After 3-5 months, blood lipid indicators can return to normal levels.

The following processes are generally used in lecithin production:

Ethanol extraction: The principle is that lecithin is soluble in ethanol, while other phospholipids: cephalin and inositol phospholipids are insoluble in ethanol.

Column chromatography: The principle is that the adsorbent has different adsorption capacities for phospholipids, inositol phospholipids and lecithin.

Co2 supercritical extraction: The principle is the abnormal equilibrium behavior and transfer performance of Co2 and lecithin at supercritical point. The different components are separated by changing the temperature and pressure.

Membrane separation method: The principle is to use different lecithin, cephalin, and inositol phospholipids to form different molecular masses in different solvents for separation. For example, passing a phospholipid solution dissolved in an ethane-isopropanol mixed solution through a polypropylene semipermeable membrane can increase the lecithin content from 25% to 51%. Recovering the solution that flows through the membrane can greatly improve the purity of the lecithin. However, this method is not very mature and cannot distinguish components with similar molecular weights. Currently limited to laboratories.
