简介
In the present study, a coating was investigated through the encapsulation of clove essential oils (CEOs) by chitosan (CS)–Myristic acid (MA) nanogel. The results of radical scavenging activity showed that the antioxidant activity of the CEOs was increased by encapsulation. Subsequently, the antibacterial activity of the coatings, i.e., free CEOs, CS–MA nanogel, and CS–MA nanogel encapsulated CEOs against Salmonella enteric Ser. Enteritidis was evaluated on inoculated beef samples. The results obtained showed that the CS–MA nanogel encapsulated CEOs was more effective compared with its free counterpart in controlling Salmonella population on beef under refrigerated storage. More specifically, the CS–MA nanogel encapsulated CEOs at only 2 mg/g beef was found promising in reducing S. enteric Ser. Enteritidis while it led to minimal unfavorable impacts on meat color values during prolonged storage …
