Innovative (ozonised water, hydrogen peroxide) treatment solutions is one of the newest treatment agents used to decrease the count of microorganisms in vegetables. NatureSeal® AS5 is a commercial solution used for the treatment of vegetables worldwide. The aim of this work was to study the effect of the various treatment solutions - hydrogen peroxide, ozonised water and NatureSeal® AS5 (in various concentrations and for different treatment time) with the main purpose to ensure the microbiological safety of fresh-cut carrots. Non-treated carrots were used as control sample. The following treatment regimes were investigated: ozonised water treatment time 60; 120; 180±1 s and concentrations 1.0; 2.0; 3.0 mg L-1; hydrogen peroxide solutions, treatment time 30±1 s, 60±1 s 90±1 s and concentrations 0.5%; 1.0% 1.5%; NatureSeal® AS5 water solution 2.5% 5 min ± 1 s were prepared for treatment of shredded carrots. E.coli in fresh carrots was not detected. Mathematical processing of the obtained results revealed that various concentrations of hydrogen peroxide (p=0.019; α=0.05) and treatment times (p=0.049; α=0.05) significantly influenced the TPC colony forming units in carrots. The obtained results prove the treatment agent properties of hydrogen peroxide. The comparison of chosen treatment regimes detected a significant (p=0.003; α=0.05) influence of the ozonised water on the decrease in the count of TPC colony forming units in carrots after treatment. During experiments it was proved that NatureSeal® AS5 solution could be recommended as treatment agent for the treatment of fresh shredded carrots. [ABSTRACT FROM AUTHOR] |
