During recent years the market for convenience foods has grown rapidly. More and more consumers prefer ready-to-eat (RTE) products because of their advantageous minimal input of time and effort. The increasing awareness of health means there is a need for nutritious, high quality ready meals. Due to technological developments, the packaging industry is continuously coming up with innovative packaging. This is being driven by ecological challenges, policy, and consumer demands. However, only a few studies have hitherto been published on innovative packaging concepts for RTE food. The purpose of this review is to evaluate the status quo and recent progress in this area. It is important to understand the crucial factors for food packaging for RTE food, namely food safety and quality. Packaging concepts have focused on preventing microbial growth, so protecting consumers from food-borne diseases. Bio-based packaging materials such as polylactic acid and chitosan have limited mechanical properties. The use of nanomaterials or natural essential oils to replace synthetic additives could alleviate this. The combination with modified atmosphere packaging showed improvements and prolongation of the shelf life.

“…Edible and non-edible films are also of interest wherein natural antimicrobial ingredients like clove, pepper, cinnamon, coffee, and others are incorporated [40,55]. Chitosan, another biologically derived polymeric biomaterial, is also being researched extensively due to its inherent, natural antimicrobial activities and non-toxicity [3,46,93].…”

Food packaging is one of the essential subject areas in food technology that play an important role in preserving all types of foods. Due to many disadvantages like a non-biodegradable and environmental problem in food packaging industry, a newer concept of use of biodegradable materials in food packaging from botanicals created tremendous innovative ideas in food packaging from past few years. An increased interest in hygiene in everyday life as well as in food, feed, and medical issues lead to a strong interest in films and blends to prevent the growth and accumulation of harmful bacteria. A growing trend is to use synthetic and natural antimicrobial polymers, to provide non-migratory and non-depleting protection agents for application in films, coatings, and packaging. The aim of this review was to offer a complete view of the state of the art on natural biodegradable polymer packages for food application compared to synthetics. Also, heightened overall developments in botanicals, natural and synthetic biopolymers in food packaging and its applications were described by focusing future improvements. This is a timely review as there has been a recent renewed interest in research studies, both in the industry and academia, towards the development of a new generation of biopolymer-based food packaging materials with possible applications in other areas. A lot of achievements in nanotechnology compared to synthetic materials attracted food industry for its wonderful applications in packaging was highlighted.

“…The positively charged amino group in chitosan is responsible for its antimicrobial character. It interacts with negatively charged microbial cell membranes and causes the leakage of intracellular constituents of the microorganisms (van den Broek et al, 2015). Chitosan films with gelatin/glycerol showed some antimicrobial effect, but it did not show an inhibitory zone towards microorganisms.…”

The antimicrobial properties of bagasse paper sheets coated with natural polymers (chitosan, different ratios of (gelatin/glycerol) + chitosan, hemicellulose, hemicellulose + glycerol, hemicellulose+chitosan) or synthetic organophosphorus dimer compounds were evaluated in this work. Hemicelluloses showed moderate activity against Bacillus subtilis and Candida albicans, while chitosan showed weak activity against B. subtilis. The condition that offered the highest inhibitory activity of bagasse paper was the one coated with 1,3-diaryl-2,2,2,4,4,4-hexachlorocyclodiphosph(V)azane (where aryl is p-chloroaniline or p-anisidine). The developed bagasse papers were evaluated against Gram-positive bacteria, Gram-negative bacteria, yeasts, and fungi. The highest inhibitory activity was obtained at a concentration of 200 mg/mL for p-chloroaniline with an inhibition zone that varied for different microbes from 6.9 mm to 26 mm. The highest inhibitory activity was obtained at 300-250 mg/mL for panisidine against most of the pathogenic microorganisms with an inhibition zone that varied for different microbes from 8 mm to 14.75 mm. The observed antimicrobial and antifungal activity properties for bagasse paper coated with 1,3-diaryl 2,2,2,4,4,4-hexachlorocyclodiphosph(V)azane could be attributed to the presence of Cl, P atoms, and the lone pair of electrons on N atoms in the structure of the dimers.
