“…This value is among the best of the state-of-the-art Ag-based antibacterial materials (1.4, 3.8, 4.5, 6.3 μg Ag cm −3 ). 24–27 The effective antibacterial activity of Ag@Zn-MOF can be attributed to the homogenously dispersed Ag sites within the alkene-functionalized Zn-MOF, which maximizes the accessibility of Ag species and reduces the use of Ag.…”

“…In fact, AP is an option, with the rationale of releasing bioactive into FPK to improve and prevent undesirable microbial growth and provide quality and safety (Jafarzadeh, Alias, et al., 2017; Jafarzadeh, Ariffin, et al., 2017). Hence, AP is gaining attention from researchers, scientists, and industries because it can simultaneously provide longer shelf life, safety, quality, and biodegradability (Babaee et al., 2022; Garavand, Rouhi et al., 2022; Zhang, Biesold, et al., 2022; Zhang, Lin, et al., 2022). AP can be defined as biodegradable packaging that carries bioactives, such as antioxidants, anti‐browning, agents, colorants, and NMs, to improve food products’ quality, safety, and shelf life and reduce the risk of microbial growth (Jafarzadeh, Hadidi, et al., 2022).…”

Non‐biodegradability and disposal problems are the major challenges associated with synthetic plastic packaging. This review article discusses a new generation of biodegradable active and smart packaging based on porous nanomaterials (PNMs), which maintains the quality and freshness of food products while meeting biodegradability requirements. PNMs have recently gained significant attention in the field of food packaging due to their large surface area, peculiar structures, functional flexibility, and thermal stability. We present for the first time the recently published literature on the incorporation of various PNMs into renewable materials to develop advanced, environmentally friendly, and high‐quality packaging technology. Various emerging packaging technologies are discussed in this review, along with their advantages and disadvantages. Moreover, it provides general information about PNMs, their characterization, and fabrication methods. It also briefly describes the effects of different PNMs on the functionality of biopolymeric films. Furthermore, we examined how smart packaging loaded with PNMs can improve food shelf life and reduce food waste. The results indicate that PNMs play a critical role in improving the antimicrobial, thermal, physicochemical, and mechanical properties of natural packaging materials. These tailor‐made materials can simultaneously extend the shelf life of food while reducing plastic usage and food waste.

“…Spraying is a widely used operation to disperse liquid into small droplets and apply droplets onto target surfaces including spraying plant nutrient solutions, fresh-keeping agents, pesticides, disinfectants, and so on. − However, only about 25–50% of the spraying liquid could deposit on target surfaces . The rest of the liquid was wasted due to floating in air as tiny droplets or rolling off from the target surface, also leading to environmental pollution.…”

Spraying is a common way to coat solutions onto surfaces evenly. Improving spraying effectiveness can avoid wasting solutions and reduce pollution. In this study, a trace amount of natural polysaccharide, konjac glucomannan (KGM), was added into solutions to regulate the spraying performances including the breakup of liquid jets, size of produced droplets, and collision and spreading of droplets on both superhydrophobic and hydrophilic surfaces. The shear viscosity, extensive viscosity, and surface tension of the KGM solutions were tested. The results of spraying experiments showed that adding KGM inhibited the liquid jet from breaking into small droplets, avoided the breakage of droplets on superhydrophobic surfaces, and promoted the spreading of liquid films on hydrophilic surfaces. The numerical simulation showed the stretching of single macromolecules and quantified the energy stored in molecular chains in a shear-dominated flow field during the spreading of droplets on surfaces and an elongationaldominated flow field during the breakage of a liquid bridge. The storage and dissipation of energy during the stretching and relaxing of KMG macromolecules were important origins of the increase in the colloid viscosity and molecular mechanisms of the effect of the KGM additive on spraying performances. This study provided an understanding and a strategy for optimization and application of spraying additives.
