The present invention discloses a freshness keeping method for cold fresh chicken. The freshness keeping method is composed of the following steps: firstly, preparing a compound biological freshness keeping agent which contains
origanum vulgare
essential oil, tea polyphenols and D-
sodium isoascorbate; secondly, using a heating
magnetic stirrer to conduct stirring for the compound biological freshness keeping fluid; thirdly, selecting healthy chickens and conducting slaughtering,
bloodletting,
