Title: Innovations by Boqiu Chen in Food-Grade Zeaxanthin Production
Introduction
Boqiu Chen is an innovative inventor based in Zhejiang, China, recognized for his contributions to the field of food-grade zeaxanthin production. With a total of two patents, Chen has significantly advanced the methodologies involved in extracting and purifying xanthophylls, particularly from plant sources, addressing both yield and industrial applicability.
Latest Patents
Chen's latest patents include a groundbreaking method for preparing high-content food-grade zeaxanthin. This invention revolves around a chemical isomerization reaction from lutein, addressing several technical challenges such as low product yield, the need for extensive purification processes, and production scalability. The method involves the following steps:
1. Mixing xanthophyll crystals or their fatty acid esters with food-grade glycol or propylene glycol at 60-90°C for complete dissolution.
2. Adding organic alkali to initiate the isomerization process under inert conditions.
3. Diluting the reaction solution with a mixture of deionized water and ethanol to isolate the crystals using conventional separation methods.
4. Vacuum drying the obtained crystals to produce zeaxanthin.
This innovative process boasts a product yield exceeding 60% and is well-suited for industrial applications without necessitating further purification treatments.
Another notable patent by Chen is related to the isolation and purification of xanthophyll crystals from plant oleoresin. This method incorporates food-grade alcohol as the organic solvent and entails saponifying plant oleoresin containing xanthophyll diesters, followed by neutralization with an acid and washing to eliminate impurities. The end result is a remarkable purity and yield, achieving up to 90% content and 80% recovery of xanthophylls, making the process both economical and practical for industrial use.
