temiz ChlRem

Material overview

TEMIZ ChlRem (Chlorophyll Remover) is a highly cross-linked adsorbent-type polymeric resin for use in separation, batch binding or scavenging of chlorophyll in polar organic solutions. Temiz ChlRem is a novel resin with effective binding towards chlorophyll in ethanolic extracts.

Structure of Chlorophyll A

Typical properties of Temiz ChlRem resins are:

  • Surface: Adsorbent-type resin 
  • Porosity: mesoporous – optimal for small molecules
  • Cross-linking: high cross-linkage
  • Particle size: ca 200 – 1200 µm

Application areas

Chlorophyll is a green pigment, found in all photosynthetic plants, and in some bacteria. In food, cosmetic and phyto-pharmaceutical products, plant extracts obtained by organic solvent extraction contain large amounts of chlorophyll. As chlorophyll may turn brown upon storage, it has to be reduced to obtain an improved extract quality. In QuEChERS, removal of chlorophyll is an important step of the work-up process for food analysis. Applications are in purification of plant extracts:  

1) removal of chlorophyll for facilitated analysis

2) removal of chlorophyll for less colored plant extracts in food and cosmetic applications

Example: Dried parsley (1 g) leaves are extracted with ethanol (30 ml) and the green extract is treated with Temiz ChlRem (1 ml Resin + 30 ml green extract).

Results: Temiz ChlRem reduces the amount of chlorophyll by up to 85 % and renders the cleaned-up green ethanol extract essentially colorless for subsequent processing or analysis.

Regeneration: Bound chlorophyll can be eluted from the resin with eg acetone. The resin regains its capacity to effectively bind chlorophyll in a subsequent resin treatment.
