Abstract

Antimicrobial packaging is a type of active packaging that exerts its antimicrobial effects through contact with food or through  release of antimicrobial agent in the packaging space and it can delay, reduce or prevent the growth of spoilage and pathogenic microorganisms in food. The aim of this study is to prepare cellulose aerosol and composite cellulose-Salep aerogel and then load it with Zataria multiflora (ZMEO) essential oil in order to release it into active antimicrobial packaging of meat to control Escherichia coli O157:H7 during refrigeration. For this purpose, two types of cellulose aerogel (1.5% W/V) and cellulose aerogel (1.5% W/v) - Salep (3% w/V) were prepared with a ratio of 1:1. By loading different amounts of ZMEO on aerogels, the minimum dose of inhibition of the vapor phase of ZMEO for E. coli was obtained 256 microliters of essential oil per liter of space. Scanning electron microscope images showed the lysis and cell destruction of E. coli, in expose to the vapor phase of ZMEO. While in the meat s amples containing 10 × MID concentration of ZMEO loaded on cellulose and cellulase-Salep aerogel, 0.93 and 0.73 logarithmic cycles of reduction in the population of E. coli after 16 days of meat storage in the refrigerator was determined. Given the importance of E. coli as one of the causes of food-borne diseases due to the lack of hygiene and the need to control it in meat, active packages containing antimicrobial compound releasers can be appropriate solution.
