Bio-based preservatives: A natural alternative to synthetic additives

In this study, the use of bio based preservatives, as a more sustainable, and health conscious alternative to synthetic additives in food preservation is investigated. The history of historical development of these natural preservatives is covered, identifying major innovations that take advantage of the antimicrobial and antioxidant properties of plant and microbial derived compounds. Some core theories and models are discussed and illustrated, which are effective in enhancing shelf life and food safety. The work reveals critical barriers to wide scale use including high costs, scalability limitations, and stringent regulatory approval processes. Barriers to the mass production of silica aerogel blanket materials are evaluated and strategies proposed to overcome these barriers are evaluated, including collaboration with regulatory bodies, the application of nanotechnology, and cost reduction techniques including optimization to raw material sourcing and leveraging of economies of scale. Synthetic preservatives are compared with tradeoffs between performance, safety, and cost, demonstrating the advantage of bio-based solutions for those applications where health and environmental considerations are important. Finally, the study suggests future research directions related to ways to increase efficacy through technological innovations, reducing cost, and making the regulatory framework more streamlined. This study provides actionable insights to food manufacturers, regulators, and consumers towards a transition to more sustainable preservation systems. Adoption of bio-based preservatives has great public health, industry usage and environmental sustainability implications.
