Online published on 10 July, 2023. Abstract Plasma is the fourth state of matters which have a wide application in food processing and post harvest technology. Plasma when applied over crops has tremendous effects in improvement in the quality and other post harvest attributes. Application of cold plasma technology could effectively induce desirable changes in its overall quality and diverse physiology. The following review would discuss the application of non-thermal plasma technology to disinfect and decontaminate processed food product and fresh horticultural crops. Horticultural crops which are treated with plasma technology do not show any loss in nutrients. The packaging materials can also be sterilized by using plasma technology. Similarly, the food packed inside a package can also be sterilized without harming the package integrity. Beside that it can also be used to reduce the enzymatic activity of fresh fruits and vegetables and help to modify the food properties. Cold plasma technology can penetrate fungal biofilm and destroy resting fungal spores. This technology can also be harnessed to remove residual toxic pesticide from food products and fresh fruits and vegetables. However, the technology might sound a bit expensive but have a long future in terms of utility. Top Keywords Cold plasma, Disinfecting food, Non-thermal plasma, Sterilization. Top |
