This work aims to develop corn starch/chitosan nanoparticles/thymol (CS/CNP/Thy) bio-nanocomposite films as potential food packaging materials that can enhance the shelf life of food. CS/CNP/Thy bio-nanocomposite films were prepared by the addition of different concentrations of thymol (0, 1.5, 3.0, 4.5 w/w%) using a solvent casting method. The resulting films were characterized in terms of optical, mechanical, and water vapor permeability (WVP) properties. The addition of thymol was found to reduce the tensile strength (TS), elongation at break (EAB), and Young’s modulus (YM) of the films. Generally, the increment in the concentration of thymol did not significantly affect the TS, EAB, and YM values. The addition of 1.5 w/w% thymol increased the WVP of the films but the WVP reduced with the increase in thymol concentrations. CS/CNP/Thy-3% bio-nanocomposite films demonstrated the potential to lengthen the shelf life of cherry tomatoes packed with the films, whereby the cherry tomatoes exhibited no significant changes in firmness and the lowest weight loss. In addition, no mold growth was observed on the sliced cherry tomatoes that were in direct contact with the films during 7 days of storage, proving the promising application of the films as active food packaging materials.

Overconsumption of plastic goods and improper handling of petroleum-derived plastic waste have brought a plethora of negative impacts to the environment, ecosystem and human health due to its recalcitrance to degradation. These drawbacks become the main driving force behind finding biopolymers with the degradable properties. With the advancement in biopolymer research, polyhydroxyalkanoate (PHA) and poly(lacyic acid) (PLA) and its composites have been alluded to as a potential alternative to replace the petrochemical counterpart. This review highlights the current synthesis process and application of PHAs and PLA and its composites for food packaging materials and coatings. These biopolymers can be further ameliorated to enhance their applicability and are discussed by including the current commercially available packaging products. Factors influencing biodegradation are outlined in the latter part of this review. The main aim of this review article is to organize the scattered available information on various aspects of PHAs and PLA, and its composites for packaging application purposes. It is evident from a literature survey of about 140 recently published papers from the past 15 years that PLA and PHA show excellent physical properties as potential food packaging materials.

Nine types of packaging materials were tested on this study Included (I) Polyethylenetetraphthalate (PET) Bottle, (ii) Polypropylene (PP) Cup, (iii) polystyrene (PS) Cup, (iv) Low density polyethylene (LDPE) Bottle, (v) Light Proof Polyethyleneterephthalate(LPET) Bottle,(vi) High density Polyethylene(HDPE) Bottle, (vii) Aluminum Cans, (viii) Glass(Emerald Green) and (ix) Cartoon bottles (250 ml size) were dispensed in the aseptic condition with Pasteurized camel milk (80 ˚C,16s) for two seasons Summer and Winter and stored immediately inside the chiller at 5 ˚C for 30 days, The camel milk samples were examined for microbial quality, sensory evaluation, also food packaging materials were examined for overall migration test, approximate shelf life of the pasteurized camel milk at temperature 5 ˚C in all types of packaging materials in our study period 30 days, Sensory Evaluation results shown that there is significant differences within best packaging materials, so we can say best packaging materials not same in summer and winter. We see also the best packaging materials is not same in winter of all type of Sensory Evaluation with one ranking (PS, HDPE) respectively, but not difference in summer, so the best in winter is (PP - PS – PET) respectively, lastly the overall migration test analysis for the food packaging materials shown that there are no significant differences within packaging materials. So we can say responds in group equally at all packaging materials and all samples meets the specification limits as per Article 12, EU 10/2011.

Recent Developments

Purpose The purpose of this paper is to acquaint the readers with recent developments in biopolymer-based food packaging materials like natural biopolymers (such as starches and proteins), synthetic biopolymers (such as poly lactic acid), biopolymer blending and nanocomposites grounded on natural and synthetic biopolymers. This paper is an attempt to draw the readers towards the advantages and attributes of new era polymers to diminish the usage of traditional non-biodegradable polymers. Design/methodology/approach Plastic packaging for food and associated applications is non-biodegradable and uses up valuable and treasured non-renewable petroleum products. With the current focus on researching alternatives to petroleum, research is progressively being channelized towards the development of biodegradable food packaging, thereby reducing adverse impact on the environment. Findings Natural biopolymer-based nanocomposite packaging materials seem to have a scintillating future for a broad range of applications in the food industry, including advanced active food packaging with biofunctional attributes. The present review summarizes the scientific information of various packaging materials along with their attributes, applications and the methods for production. Originality/value This is an apropos review as there has been a recent renewed concern in research studies, both in the industry and academe, for development of new generation biopolymer-based food packaging materials, with possible applications in many areas.
