Advances in bio food packaging – An overview

Abstract

In recent years, there has been an increase in demand for bioactive techniques in the food packaging industry. Although edible packaging is popular, it has yet to be effectively implemented into the market. Packaging made of plastics and chemicals is widely employed in the market today, posing a threat to the environment and living creatures. This research attempts to show current breakthroughs and progress in the field of biodegradable packaging. When compared to ancient packaging materials, bio-based packaging materials are safer. Sustainable biodegradable packaging materials can be made from edible films, coatings, and other bio food packaging techniques made from various biological resources. This paper discusses the important qualities and advantages of several bio-based packing materials. It is highlighted the advantages of bio-based packaging materials over synthetic packaging materials. It has been debated the importance of employing bio-based packaging to mitigate the environmental risks associated with traditional packaging technologies. Many researchers may be prompted by this study to focus on packaging reformulation options. Thus, we can attain food packing materials by considering customer's economic and sustainability aspects.

Application of Edible Packaging in Dairy and Food Industry

“…Partial acid or alkali hydrolysis of collagen is used to produce gelatin at high temperature in the presence of water. Due to unique properties of gelatin, it is widely used in cosmetics, food, pharmaceuticals, industry [30]. Edible film obtained from gelatin has impermeability to CO 2 and flexibility due to its random arrangement of polypeptide chain in water solution [31].…”

“…Antimicrobial compounds are additives used to control biological deterioration and to inhibit the growth of microorganisms, including pathogenic microorganisms. Antimicrobial agent can be incorporated directly into the food during manufacturing or may be incorporated into food packaging materials [30]. There are several groups of antimicrobial compounds potentially incorporated into edible films, including chemical agents, natural extracts and probiotics.…”

“…The most employed antimicrobial enzyme is lysozyme which is made up of hydrophilic monopeptide chains [30]. Lysozyme is a nutraceutical and is produced from egg white, milk and blood [105].…”

“…Gram-negative bacteria have lipid-based outer cover to their cell walls; due to this, lysozyme is less effective on it [15]. By hydrolysing the peptidoglycan, lysozyme causes bacterial death by destroying the cell wall of bacteria [30].…”

Recent Advancements in Smart Biogenic Packaging: Reshaping the Future of the Food Packaging Industry

“…Moreover, extensive research on the array of biogenic polymers must be conducted, to determine an appropriate strategy contributing to the production of superior quality packaging at a justifiable cost. In the world of food packaging, a broad consortium of biopolymers supplemented with a range of bioactive compounds from plant and animal sources could be a viable substitute [179].…”
