Perceptions and Effectiveness of Seven Food Preservation Methods While Maintaining Nutritional Value

This paper presents the perceptions and effectivity of seven food preservation methods with a focus on extending shelf life while maintaining nutritional food value. The methods discussed include High-Pressure Processing (HPP), Pulsed Electric Fields (PEF), Modified Atmosphere Packaging (MAP), Edible Coatings and Films, Cold Plasma Treatment, Irradiation, and Nanotechnology Applications. A comparative analysis was undertaken to determine the effectiveness, strengths, and weaknesses of each method. There were 40 respondents who shared their views and experiences on the various advanced food preservation methods. Survey data indicate varying degrees of consumer familiarity and acceptance, as well as perceived benefits and concerns regarding these technologies. The findings suggest that combining multiple preservation techniques can optimize outcomes by leveraging the unique advantages of each method. The paper concludes with recommendations for integrating advanced preservation methods, enhancing consumer education, investing in research and development, advocating for regulatory support, tailoring solutions to specific food categories, and prioritizing sustainability. Thus, by implementing these seven preservation methods, the food industry can achieve improved food safety, extended shelf life, and better nutritional quality, ultimately benefiting both producers and consumers.
