The present disclosure discloses a method for reducing
benzopyrene and plasticizers in
capsicum oleoresin and a product obtained thereby. The method includes steps: dissolving
crude oil paste of
capsicum oleoresin as
raw material with a small molecular
alcohol solvent to obtain a small molecular
alcohol solution of
capsicum oleoresin; performing extraction and back-extraction with CO2 and small molecular
alcohol solvents, respectively in a supercritical two-stage series mode; performing extracting on the small molecular alcohol solution by using CO2 in extraction kettle I, to obtain a CO2 extract phase and a
raffinate phase (small molecular alcohol phase); obtaining high-purity capsicum
oleoresin with reduced
benzopyrene and plasticizers by conducting vacuum concentration and
residual solvent removal on the small molecular alcohol phase; performing back-extraction on the CO2 extract phase by using a small molecular alcohol
solvent after the CO2 extract phase enters extraction kettle II, so as to obtain small molecular alcohol phase, which is used for dissolving the
crude oil paste of capsicum
oleoresin in the next batch. The present disclosure improves the content and yield of refined capsicum
oleoresin products and removing
odor,
benzopyrene, and plasticizers. Additionally, in the present disclosure, the removal efficiency of plasticizers, benzopyrene, and odors in capsicum oleoresin extracts may be improved, and the levels of benzopyrene, plasticizers, and inherent odors in the
capsicum extract are reduced to extremely low levels, so that capsicum oleoresin may be significantly superior to products produced in prior art.
