Title:
METHOD FOR PRODUCING REDUCED CHLOROPHYLL-CONTAINING COMPOSITION, AND METHOD FOR PREVENTING CHLOROPHYLL-CONTAINING PLANT BODY FROM LOSING COLOR
Document Type and Number:
WIPO Patent Application WO/2022/070919
Kind Code:
A1
Abstract:
Provided is a technique for preventing a plant body such as powdered green tea from losing the green color thereof. A slurry that contains a chlorophyl-containing plant body is flowed into a copper pipe, the plant body being a fluid in the slurry. Due to the foregoing, the plant body comes into contact with the copper exposed on the inner surface of the copper pipe, thereby reducing the chlorophyl of the chlorophyl-containing plant body. The reduced chlorophyll-containing composition thus stably obtained exhibits green color, due to the coordinated bonding between copper and the center of the tetrapyrrole ring of the chlorophyl. In this manner, due to this configuration, color loss from a chlorophyll-containing plant body can be prevented.
