The present invention discloses a cold fresh chicken compound freshness keeping agent. Every 100 ml of the compound freshness keeping agent contains 0.7 grams of
origanum vulgare
essential oil, 0.15 grams of tea polyphenols, 0.03 grams of D-
sodium isoascorbate, and the balance being
ethanol having a
volume concentration of 10%, and the above components are stirred by a heating
magnetic stirrer at a moderate speed at 60 DEG C for 5 minutes. The slaughtered, cooled, disinfected, and washed and cleaned fresh chicken meat is classified, placed and soaked in the compound biological freshness keeping agent for 1 minute, and is taken out, drained at
room temperature, packed using PE bags, and stored at 4 DEG C. By conducting sensory evaluation and detecting pH, volatile basic
nitrogen (TVB-N) and the total number of colonies of chicken meat, using the compound biological freshness keeping agent to preserve the cold fresh chicken is found to be able to better
delay the decay and deterioration of the cold fresh chicken, prevent microbial growth and
reproduction, and significantly prolong the
shelf life of cold fresh chicken by 5-6 days as compared with the conventional
cold storage technology. The compound freshness keeping agent is safe and reliable to prepare, is simple and practicable, and has low cost and certain application and promotion values.
