“…The newly fabricated materials are intended for application in packaging, requiring a thorough safety assessment. 42 The liver, being the largest organ in the human body and anatomically a highly metabolic organ, is susceptible to the effects of various toxins present in the systemic circulation. Additionally, it plays a vital role in removing xenobiotic compounds from the blood.…”

A biopolymer-based formulation for robust and active food packaging material was developed. This material consisted of a blend of three biopolymers (guar gum−sodium alginate−icarrageenan) reinforced by cellulose nanocrystals (CNC) alongside the integration of silver nanoparticles (AgNPs) with varying sizes. The CNC utilized in this process was derived from cloth waste lint (CWL) generated from a household cloth dryer machine. This CNC synthesis underwent a series of solvent treatments to yield the CNC used in the composite. CNC and AgNPs were incorporated into the tribiopolymeric blend matrix to construct a nanocomposite film that showed excellent tensile strength (∼90 MPa). The nanocomposite film also exhibited antimicrobial activity against Escherichia coli ATCC 25922 and Bacillus cereus MTCC 1272. In this report, it was demonstrated that the zone of inhibition against E. coli and B. cereus depends on the variation of size and amount of AgNPs inside the polymeric matrix. The practical applicability of such a film was also demonstrated by applying it to sliced bread and the enhancement of the shelf life of the raped bread was compared with a control. Thus, the guar gum−sodium alginate−i-carrageenan tribiopolymer blend with a cloth waste lint extracted cellulose nanocrystal composite film is antimicrobial, hence, an excellent candidate as an active packaging film.

“…The packaging material's ability to negatively impact the environment after its purpose can be identified by studying the interaction of the films with the soil. 42 The soil degradation percentage per day of the films was experimented as 6.12% for film 1, 2.16% for film 2, 3.13% for film 3, and 2.81% for film 4 (Supporting Information: Table S4).…”

Nanotechnology offers an innovative application as an eco-friendly food packaging film fabricated along with a degradable active mixture (AM). The AM is an assortment of alloyed metal oxide nanoparticles (Ag–ZnO), citron powder (AA), and Curcuma peel powder (CPP). Alloyed nanoparticles (NPs) were observed to exhibit a hexagonal structure from the experimental X-ray diffraction. Compositional and morphological study of the NPs (22.69 nm) and AM (32 nm) was done using energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and ζ- potential was observed to be −14.7 mV, indicating the stability of NPs. The prepared film was observed to be more effective with antibacterial analysis against Escherichia coli, exhibiting 72% of inhibition and antioxidant activity with IC50: 51.56% using the 2,2 diphenyl-1-picrylhydrazyl (DPPH) assay. Film 1, Film 2, Film 3, and Film 4 were fabricated with the AM and observed to be perfectly encapsulated by PVA using XRD. FESEM images of the film exhibit the aggregation of NPs with biocomposites in perfect distribution. The mechanical properties such as Young’s modulus, elongation at break, tensile strength, and ultimate tensile strength (UTS- 5.37 MPa) were experimented for the films. The degradation rate was observed to be 6.12% for film 1 using the soil burial method. The study emphasizes that NPs along with biocomposite upgrade the sustainability of the packaging film with improved mechanical and physicochemical properties. The synthesized film with biomaterials could be used as a “green” food package to store fruits, vegetables, and sweets in the food industry.

“…8 To impart the anticipated properties to starch, various approaches have been implemented, including modification of starch, 9,10 plasticization using various low molecular weight plasticizers, 11–13 eutectic solvents, 14 blending of polymers, 15–18 reinforcement of active ingredients such as essential oils, 19–21 natural extracts, 22,23 and nanoparticles ( e.g. , quantum dots, 14 cellulose, ceramics, 13 metals and metal oxides 24 ). The property improvement approaches were quite successful; however, more attention is required so that edible starch-based packaging could increase the market share of EFs in the packaging industry.…”
