نشریه بین المللی نوآوری در علوم کشاورزی و توسعه روستایی 4 3 Investigation of microbial load of industrial dried vegetables based on cold plasma Investigation of microbial load of industrial dried vegetables based on cold plasma 1 7 10.22051/jera.2021.31891.2698 FA Mohadeseh Mahdis Moradi -Mohadeseh Eslami Kanafi-Seyed Davood Mir Sadeg -Melika Zandi -Samira Yazdankhah -Amir Reza Herzvi -Abalfazl Yazdankhah 2024 02 24 Abstract Nowadays, food industry experts consider the use of cold plasma method as a non-thermal method for reducing microbial load and cold sterilization. In this study, the antimicrobial effect of cold plasma was considered in order to provide microbial safety. The aim of this study was to investigate the effect of cold plasma on the work cycle (8, 12 and 16) percent and different times (2.5, 5 and 10 minutes) to evaluate the microbial properties of cold plasma treatments. The results of this study showed that with increasing the duration of effectiveness with cold plasma, the growth rate of bacteria such as total microorganisms, mold and yeast, Escherichia coli, and Enterobacteriaceae decreased significantly, and was negative in Staphylococcus aureus (P <0.05). It should be noted that the microbial quality of cold plasma-treated treatments was much lower than the control treatment. In general, the results of this study showed that the use of non-thermal cold plasma in dried vegetables maintains and improves the nutritional value without adversely affecting the treatments, and is also a good alternative to thermal depollutionizing methods.
