Latest Patents

Hongping Lv holds a notable patent titled "Method for preparing high-content food-grade zeaxanthin." This invention addresses several technical challenges associated with existing methods of zeaxanthin production. Traditional processes often yield low amounts of the desired product, require extensive purification treatments, and struggle to scale for industrial production.

Lv's revolutionary method involves a series of carefully controlled steps: 1) Mixing xanthophyll crystal or its fatty acid ester with food-grade glycol or propylene glycol at elevated temperatures (60-90°C) for complete dissolution. 2) Introducing an organic alkali to initiate an isomerization reaction under inert conditions. 3) Diluting the resulting solution with a mixture of deionized water and ethanol, followed by separation of the crystal using conventional techniques. 4) Finally, vacuum drying the crystals to obtain high-purity zeaxanthin. Notably, this method achieves a product yield of over 60% and is highly adaptable to industrial-scale production, eliminating the need for further purification treatments.
