How To Ensure Quality Of Food-Grade Egg Lecithin?
Guanjie Biotech ensures that the quality of extracted bulk egg yolk lecithin meets food grade standards, which requires strict control from multiple aspects such as raw material selection, production process, quality inspection, and standard compliance. The following are specific measures.
1. Select suitable raw materials
The raw materials for lecithin should be fresh egg yolks or high-quality egg yolk powder. We must ensure that the source of raw materials is clear, legal, and in compliance with relevant regulations and standards.
2. Follow scientific production processes
• Solvent selection:
Use food-grade solvents. Such as anhydrous ethanol and acetone. These solvents must meet food additive standards and avoid the use of industrial-grade solvents.
Process optimization:
Optimize extraction conditions, such as ethanol concentration (95%~100%), extraction temperature (20℃~50℃), extraction time (30~60 minutes), etc., to ensure high purity and high yield of lecithin.
• Remove impurities:
Remove residual oil, solvents, and other impurities through multiple centrifugation, washing, and drying.
3. Strict quality testing
• Chemical index testing:
The nitrogen content of lecithin should be 1.75%~1.95%, and the phosphorus content should be 3.5%~4.1%. Ensure that the product does not contain heavy metals (such as lead, and arsenic), pesticide residues, and solvent residues.
• Microbial testing:
Test indicators such as total colony count, coliform group, mold, and yeast to ensure that the product meets hygiene standards.
• Stability testing:
Evaluate the stability of egg yolk lecithin powder through indicators such as peroxide value and acid value.
4. Follow food safety standards
• National standards:
The production and quality control of bulk egg yolk lecithin must comply with "GB 1886.358-2022 National Food Safety Standard Food Additives Lecithin".
• International standards:
Refer to the requirements of the "Food Chemical Code" (FCC) to ensure product purity and safety.
5. HACCP system:
Establish a hazard analysis and critical control point (HACCP) system during the production process to ensure the safety of each production link.
Applications:
1. Medical field:
Egg yolk lecithin is mainly used as an emulsifier and pharmaceutical excipient in the pharmaceutical industry, and can be used to prepare injection emulsions, liposomes, etc.
High-purity egg yolk lecithin (such as PC-98T) can be used in high-end preparations such as alprostadil lipid microspheres.
2. Health care function:
Lecithin is an important component of cell membranes, which helps regulate blood lipids, prevent arteriosclerosis, and improve memory and nerve function. Egg yolk lecithin powder can also repair damaged brain cells and promote the development of the brain's nervous system.
3. Food and cosmetics:
Egg yolk lecithin can be used in the food industry as an emulsifier and stabilizer. In cosmetics, it can be used in moisturizing and anti-aging products. In cosmetics, the application of egg yolk lecithin is mainly based on its multiple functional properties.
-Moisturizing effect
Egg yolk lecithin has good moisturizing properties, which can increase the water content of the stratum corneum and help the skin retain moisture. It can reduce water loss by forming a moisturizing barrier while penetrating deep into the skin and activating skin cells.
-Emulsification
As a natural emulsifier, egg yolk lecithin can effectively reduce the tension of the oil-water interface and help form a stable emulsion system. This allows the oily and aqueous components in cosmetics to be evenly mixed, improving the stability and feel of the product.
-Antioxidant and anti-aging
Egg yolk lecithin has antioxidant ability, can scavenge free radicals, reduce oxidative damage, and thus delay skin aging. It can also repair damaged cell membranes, promote the regeneration of skin cells, and improve the overall health of the skin.
-Skin conditioning
Bulk Egg yolk lecithin powder is an important component of the cell membrane. It can enhance the skin barrier function and reduce problems such as dryness, redness, and peeling of the skin. Moreover, it can soothe the skin and reduce inflammation, making it suitable for the care of sensitive skin.
-Hair care
In hair products, egg yolk lecithin can be used to nourish hair and enhance its luster and elasticity. It can stimulate hair growth and has a certain effect on the treatment of seborrheic alopecia.
Safety
Egg yolk lecithin is a natural ingredient. It is highly safe, mainly reflected in the following aspects.
•Ingredients and biocompatibility
Egg yolk lecithin is a natural ingredient, mainly composed of phospholipids such as phosphatidylcholine and phosphatidylethanolamine. These ingredients are important components of human cell membranes, have good biocompatibility, and can be naturally accepted by the skin and human tissues.
•Low risk factor
In cosmetics, the risk factor of lecithin (including egg yolk lecithin) is 1-3, which is a low level. This means that it is minimally irritating to the skin under normal conditions of use and will not cause severe allergic reactions.
•Non-comedogenic
Bulk Egg yolk lecithin is not comedogenic, does not clog pores, and is suitable for all skin types, including sensitive and oily skin.
•Safety for pregnant women
Due to its natural origin and low-risk factor, egg yolk lecithin is an ingredient pregnant women can use. It is not only safe for pregnant women but also provides support for the development of the fetus's nervous system.
•Low skin irritation
Egg yolk lecithin powder has good hydrophilicity and lipophilicity, which can soften and soothe the skin while forming a protective barrier on the skin surface. It also has anti-inflammatory effects and can reduce inflammatory responses in the skin.
•Evaluation by international authoritative organizations
According to the conclusion of international authoritative cosmetic safety assessment organizations, using bulk egg yolk lecithin in cosmetics is safe. In addition, injection-grade egg yolk lecithin is widely used in fat emulsion injections in the medical field because it is highly safe and does not cause hemolysis or neurotoxicity.
