Inhibitory Activity of Chlorogenic Acids in Decaffeinated Green Coffee Beans against Porcine Pancreas Lipase and Effect of a Decaffeinated Green Coffee Bean Extract on an Emulsion of Olive Oil

Abstract

A decaffeinated green coffee bean extract (DGCBE) inhibited porcine pancreas lipase (PPL) activity with an IC₅₀ value of 1.98 mg/mL. Six different chlorogenic acids in DGCBE contributed to this PPL inhibition, accounting for 91.8% of the inhibitory activity. DGCBE increased the droplet size and decreased the specific surface area of an olive oil emulsion.
