ABSTRACT

Today, global food systems are highly susceptible to food safety risks, economic shocks, price volatility, and natural disasters and pandemics, such as the novel coronavirus (COVID-19). This paper draws from research on food and nutritional security, food fraud and associated economic ecosystem, and the disruptions due to COVID-19 for socio-economic inequality globally. It is concluded that the safety risks have pushed enforcement of measures to reduce food supplies, adversely impacting food availability. Also, COVID-19 is likely to raise fleeting food security and nutritional concerns across the globe, resulting in rises in poverty and food fraud, limiting food supply and access. Accelerated investments intended to develop more inclusive, sustainable, and resilient food systems will help shrink the effect of the pandemic and, hence, offer a way to control the foreseen food security crisis and economic growth.

ABSTRACT

Food processing plays a crucial role in coping up with the challenges against food security by reducing wastage and preventing spoilage. The ultrasound technology has revolutionized the food processing industry with its wide application in various processes, serving as a sustainable and low-cost alternative. This non-destructive technology offers several advantages such as rapid processes, enhanced process efficiency, elimination of process steps, better quality product and retention of product characteristics (texture, nutrition value, organoleptic properties), improved shelf life. This review paper summarizes the various applications of ultrasound in different unit operations (filtration, freezing, thawing, brining, sterilization/pasteurization, cutting, etc.) and specific food divisions (meat, fruits and vegetables, cereals, dairy, etc.) along with, the advantages and drawbacks of the technology. The further scope of industrial implementation of ultrasound has also been discussed.
