1. Product & Application Background

AB103 is a specialized resin with specific adsorption capacity for aromatic and hydrophobic small-to-medium molecular weight organic compounds. In the natural product extraction industry, it serves as a core material for the extraction and purification of anthocyanins and water-soluble natural pigments. It is ideally suited for industrial production of various natural pigments, including Solanum nigrum fruit magenta pigment, purple sweet potato anthocyanin, red cabbage anthocyanin, and black radish anthocyanin, and can also be extended to the adsorption and extraction of stevioside and other natural products.

2. Core Application Process (Taking Solanum nigrum Fruit Magenta Pigment Extraction as an Example)

The complete industrial process for extracting Solanum nigrum fruit magenta pigment with AB103 is clear, controllable, and scalable for large-scale production:

1. Acid Water Extraction: The Solanum nigrum fruit raw material is soaked and extracted with acid water to obtain a crude extract containing magenta pigment.

2. Resin Adsorption & Rinsing: The extract is passed through an AB103 resin column, where the resin efficiently captures the target anthocyanin pigments while removing impurities via its specific adsorption properties.

3. Ethanol Elution: The resin column is eluted with 50% ethanol to obtain a high-purity pigment desorption solution.

4. Concentration & Drying: The desorption solution is concentrated under reduced pressure and dried to yield the final Solanum nigrum fruit magenta pigment product.

3. Application Advantages & Value

1. High Adsorption Selectivity: AB103 exhibits strong targeted adsorption for anthocyanins and other aromatic, hydrophobic natural pigments, enabling efficient separation of pigments from raw material impurities and significantly improving product purity.

2. Strong Process Compatibility: Beyond Solanum nigrum pigment extraction, it is directly applicable to the extraction and purification of anthocyanins from various raw materials such as purple sweet potato, red cabbage, and black radish, offering excellent versatility.

3. Industrial-Friendly Design: The process is simple, easy to scale up, and the eluent (ethanol) is recyclable, meeting the environmental and cost requirements of the food and natural product extraction industries.

4. Broad Expandability: In addition to natural pigment extraction, AB103 covers related natural product extraction scenarios such as stevioside adsorption and decolorization and refining of fruit juice and sugar solutions, providing a one-stop solution for enterprises.

4. Target Customers

This solution is suitable for natural product extraction enterprises, food additive manufacturers, and pigment processing companies. It helps customers improve pigment extraction efficiency, reduce production costs, and obtain high-purity, high-quality natural anthocyanin products.
