Description

solid

Solid

A form of chlorophyll that absorbs light in the violet to red spectrum (approximately 400-700 nm wavelength range) and reflects green light (500-570 nm wavelength), which imparts the characteristic green color to land plants. It is essential for oxygenic PHOTOSYNTHESIS.

Chlorophyll a Use and Manufacturing

Methods of Manufacturing

It is obtained by extracting leaves or silkworm manure of clover, daisy, spinach, cabbage, nettle and other plants with organic solvents (acetone, butanol, methylene chloride, ethanol, petroleum ether, isopropanol, trichloroethylene, butanone). Or it can be obtained by extracting by-products of corn long beard products, followed by removing (or not removing) the magnesium in the complex, and removing the solvent.

Uses

Chlorophyll A is a photosynthetic pigment that is essential for photosynthesis of eukaryotes and cyanobacteria, acting as a primary donor in the electron transport chain. Food green coloring. Used in cakes, beverages, liqueurs, etc. In fact, plant leaves or dry powder are often used directly. For example, tea powder, mugwort, spinach, chlorella, etc. Adding to gum can eliminate bad breath. Chlorophyll is used to color soap, mineral oil, wax and essential oils. Chlorophyll or chlorophyllin derivatives, such as copper chlorophyll [11006-34-1], sodium iron chlorophyllin, sodium copper chlorophyllin, used in food, candy, beverage, toothpaste, etc. as coloring agent and deodorant. Chlorophyllin derivatives can be used in the formulation of odorous cosmetics together with bactericides such as Zeolite and Locaban. Can be used as a non-toxic colorant for soap, fat, oil wax, food, cosmetics and medicine
