This study contemplates the factors that influence consumer intention, before and during the eruption of COVID-19, for the selection of healthy packaged food in Pakistan. The extant studies have identified two distinct attitudes of consumers about food label information: one is its usefulness and the second elucidates the avoidance. Hence forth, the current study contributes to the extant literature while signifying both reasons which motivate consumers to read food labels and reasons which discourage consumers from consult food labels at the point of purchase. Moreover, the impact of subjective norms and self-efficacy for healthy packaged food intentions has also been examined for both before the emergence of COVID-19 and during the spread of COVID-19. The underpinning of the proposed model has been justified by the behavioral reasoning theory. The cross-sectional data of 14,455 students has was collected from 10 universities through Microsoft Teams and Zoom. AMOS 21 was employed for the final analysis. The results indicate that before COVID-19 the subjective norms and self-efficacy were not the stimulating factors for the selection of healthy packaged food. On the contrary, during the COVID-19 outbreak, the subjective norms and self-efficacy divulged a significant effect. Moreover, the reasons to consult food labels are positively significant whereas the reasons to avoid food labels have negatively affected the consumer, both before COVID-19 and during COVID-19 outbreak, while endorsing healthy packaged food. Conclusively, COVID-19 has been proved to be a deterrent for unhealthy packaged food lovers while being a blessing for healthy packaged food.

With the worldwide transformation to a circular and low-carbon economy, the demand for sustainable materials has skyrocketed in recent years. Of various methods, sustainable and biodegradable biopolymers derived from renewable bioresources have received significant interest. Synthetic biodegradable biopolymers offer tremendous advantages over natural biodegradable biopolymers due to their stability, flexibility, and a wide range of achievable properties to fit several applications.

Biodegradable plastics are increasingly utilized in packaging, driven by green chemistry and environmental responsibility. Among them, poly(L-lactic acid) (PLLA) stands out due to its biodegradability and biocompatibility. However, its limited gas permeability and selectivity hinder its application in produce preservation.

The advancement of active packaging for food conservation has attracted considerable interest over time. In the present study, we aims to create and examine active films composed of chitosan (CS), poly(vinyl alcohol) (PVA), and syzygium guineense plant extract (SYZ) for potential use in food preservation. We examined the impact of ethanol extracts from the SYZ plant on the films' tensile strength, physical, antibacterial, and anti-oxidant properties.

In this study, a pyrolysis-gas chromatography/mass spectrometry method was established to quantify microplastics (MPs) released from plastic food containers during rinsing and migration. The inner surface of actual samples was rinsed with deionized water, and the MPs in rinse water were collected through a glass fiber membrane with pore size of 1 μm. Subsequently, thoroughly cleaned polypropylene (PP) food packaging containers were selected for migration tests under different simulants, migration temperatures, and migration times.

The present study included the environmentally friendly production of stable nickel nanoparticles (NiO NPs) using lemon and tomato, followed by their analysis and evaluation for their antibacterial properties against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Bacillus cereus. The Nickel oxide nanoparticles produced exhibited their maximum absorption at 276 nm in the UV-vis spectrum. The image captured FESEM revealed smooth nanofibers with an average diameter of around 259 ± 3.
