Phospholipids Wholesale Price,Production Technology

The production process of phospholipids mainly includes raw material preparation, fermentation, and extraction. Below is a detailed introduction:

1. Raw Material Preparation

The production of phospholipids requires suitable raw materials. Common raw materials include phosphoric acid, glycerol, and fatty acids. After pretreatment, these materials can be used in subsequent fermentation and extraction steps.

2. Fermentation

·Mixing Raw Materials: Phosphoric acid and fatty acids are mixed in a certain ratio, and glycerol is added as a carbon source.

·Fermentation Strains: The mixture is transferred to a fermentation tank, where an appropriate amount of fermentation strains is added. The selection of strains and cultivation conditions is crucial for product quality.

·Fermentation Conditions: Fermentation is generally conducted under suitable temperature and pH conditions to facilitate the catalytic reaction between phosphoric acid and fatty acids. The fermentation time usually lasts several days, during which parameters like temperature, pH, and stirring of the fermentation broth need to be controlled to promote microbial growth and metabolism.

3. Extraction

·Separating the Fermentation Broth: After fermentation is complete, the broth is separated, typically using centrifugation or filtration. The separated fermentation broth contains phospholipids and other impurities.

·Solvent Extraction: To obtain high-purity phospholipid products, further extraction is necessary. The common extraction method is solvent extraction, which involves mixing the separated fermentation broth with an appropriate organic solvent. Through stirring, the phospholipids combine with the solvent, forming a layer of solution and a layer of solid. Centrifugation or filtration is then used to obtain solid phospholipids.

4. Refining Process

The extracted phospholipid product also requires refining to remove residual solvents and other impurities. Common methods include evaporation, washing, and freezing. After multiple treatments, a high-purity phospholipid product is obtained.

Additionally, when producing phospholipids from soybeans, the production process includes the following steps:

·Degumming: Phospholipids are separated from fats through a hydration reaction. The degumming process can be categorized into batch and continuous methods.

·Batch Method: Crude oil is added to a reaction tank, heated, and then a certain amount of water and additives (such as acetic anhydride) are added to promote a thorough hydration reaction between the oil and water under stirring conditions.

·Continuous Method: The raw crude oil undergoes hydration, phospholipid separation, and finished product storage in a continuous manner. The feeding method involves simultaneously introducing a measured amount of water or steam with the oil into the pipeline, allowing for thorough mixing of the oil and water.

·Dehydration: Dehydration treatment is performed on the degummed oil using concentration equipment (such as a thin-film evaporator). Both batch and continuous dehydration methods can be employed.

·Decolorization: Phospholipids are decolorized using bleaching agents like hydrogen peroxide.

·Drying: The phospholipids are dried in batches, with vacuum drying being the most commonly used method. However, care must be taken to prevent foaming during vacuum drying by carefully controlling the vacuum level and employing longer drying times. Thin-film drying is also a commonly used drying method.

·Refining: Impurities in crude phospholipids are removed to obtain a higher content of phospholipids. This usually involves mixing crude phospholipids with acetone in a certain proportion and continuing stirring under cooling conditions. After the phospholipids precipitate, they are separated and then dried.

The production process of phospholipids involves multiple steps and stages. Proper control of process parameters and the use of suitable equipment are essential for obtaining high-quality and high-yield phospholipid products.
