The sustainable food supply is a growing concern due to spoilage microorganisms, and food industries need advanced technologies to maintain nutritive content, enhance bioavailability, provide sustainability, and meet consumers' sensory requirements. Non-thermal processes, such as PEF, sonication, HPP, cold plasma, and pulsed light, offer promising solutions by improving food quality, reducing water utilization, decreasing emissions, and utilizing by-products. HPP technology shows positive results in reducing spoilage microorganisms while retaining nutritional value, meeting the requirements for sustainable and clean labeled food production.
Sustainable food supply has gained considerable consumer concern due to the high percentage of spoilage microorganisms. Food industries need to expand advanced technologies that can maintain the nutritive content of foods, enhance the bio-availability of bioactive compounds, provide environmental and economic sustainability, and fulfill consumers' requirements of sensory characteristics. Heat treatment negatively affects food samples' nutritional and sensory properties as bioactives are sensitive to high-temperature processing. The need arises for non-thermal processes to reduce food losses, and sustainable developments in preservation, nutritional security, and food safety are crucial parameters for the upcoming era. Non-thermal processes have been successfully approved because they increase food quality, reduce water utilization, decrease emissions, improve energy efficiency, assure clean labeling, and utilize by-products from waste food. These processes include pulsed electric field (PEF), sonication, high-pressure processing (HPP), cold plasma, and pulsed light. This review describes the use of HPP in various processes for sustainable food processing. The influence of this technique on microbial, physicochemical, and nutritional properties of foods for sustainable food supply is discussed. This approach also emphasizes the limitations of this emerging technique. HPP has been successfully analyzed to meet the global requirements. A limited global food source must have a balanced approach to the raw content, water, energy, and nutrient content. HPP showed positive results in reducing microbial spoilage and, at the same time, retains the nutritional value. HPP technology meets the essential requirements for sustainable and clean labeled food production. It requires limited resources to produce nutritionally suitable foods for consumers' health.
