“…The OTR values of NI/MSN membrane and 1MSN/NI/PLA membrane were reduced by about 14.81% and 27.31%, respectively, relative to PLA membrane. The addition of modified nisin and MSN to the PLA matrix increases the distance of O 2 through the route, forming a zigzag route that acts as a barrier to O 2 30,40 . And for 2MSN/NI/PLA and 3MSN/NI/PLA membranes, the reductions were 32.87% and 34.72%, respectively.…”

Nisin was loaded in mesoporous silica nanoparticles (MSN) (0, 1, 2 and 3 wt%) and incorporated into poly (lactic acid) (PLA) matrix by casting method. The mechanical property, water vapor permeability, thermal property, and antimicrobial property of PLA nanocomposite films were measured. And the internal structure of the composite film was observed through the Scanning electron microscope. Meanwhile, the kinetic of nisin releasing from food simulated solution was investigated and the migration model was established. The result showed that mesoporous silica had an effect on the mechanical and thermal property of the composite films. Both water vapor transmission rate (WVP) and oxygen permeation rate (OTR) decreased, especially for 3MSN/NI/PLA, where WVP decreased by about 9.64% and OTR decreased by 35.19%, which was beneficial to improve the preservation effect. With the addition of MSN, the amount of loaded nisin increased, and at 3MSN/NI, the nisin loading reached 88.75%, and the mesoporous silica could effectively control the release of nisin, thus prolonging the preservation effect. The release kinetic of nisin was described by Fick's law and Weibull's model. In short, the PLA nanocomposite film has the potential to be used as an antimicrobial active film by adding nisin as an antimicrobial agent.Highlights A biodegradable antimicrobial food grade film was prepared. Nisin was added to the films as an antimicrobial agent. The ordered mesoporous structure of MSN was used as a carrier of antimicrobial agent. The film effectively inhibits E. coli and S. aureus by controlling the release of nisin. Fick's law and Weibull's model were used to describe the release kinetics of Nisin.

“…319 PLA has been granted "Generally Recognized as Safe" (GRAS) status by the US Food and Drug Administration (FDA) and can be used as a packaging material capable of coming into contact with food and beverages (Figure 6). [320][321][322][323] PLA can be used to produce plastic bottles for water; however, its barrier properties are low and therefore it is not recommended for storing some types of beverages. 324 Regarding its mechanical performance, PLA is brittle, [325][326][327] with less than 10% elongation at break 328,329 and has low impact resistance (commonly mentioned value: 2.5 kJ/m 2 ), [330][331][332] so its use is limited for some applications.…”

The limited degradation of synthetic polymers used in food packaging when discarded in the environment is a major concern for society. Therefore, industry and academia have sought to develop biodegradable and eco-friendly materials for single-use in packaging. An interesting alternative for the food industry is biodegradable polymeric films, which is why different biopolymers have been used in the production of sustainable packaging. It is worth mentioning that the use of biodegradable polymers is one of the most successful innovations in the industry to address issues related to the environment. Among the available raw materials, starch extracted from different renewable sources is very promising for this purpose, due to its abundance, low-cost compared to other polymers and ability to produce non-toxic films. However, when used alone, pure starch has many limitations, which can be overcome by developing a mixture with other polymers (polymer blends), preferably from renewable and biodegradable sources, such as poly(lactic acid) (PLA). In this context, the absence of literature reviews evidencing the results of the application of films in foods led us to write this article, given the importance of polymer blends produced with different types of starch (cassava, corn, pea, potato, rice and wheat) and the PLA matrix. According to the results, it is clear that polymer blends based on PLA/Starch for food packaging are very promising, already being part of the industries solutions, aiming to minimize the large volume of plastic waste of petrochemical origin discarded in nature. Obviously, as with any technology, more research is needed to further improve the performance of the films, and while much research has made great strides, there are still limitations that prevent the commercialization of these materials.

Porphyrinic Metal–Organic Framework-Loaded Polycaprolactone Composite Films with a High Photodynamic Antibacterial Activity for the Preservation of Fresh-Cut Apples

Food-borne diseases caused by fresh fruits and vegetables seriously threaten human health. The polycaprolactone (PCL) polymer with good biodegradability has drawn growing interest in packaging and protecting of fresh fruits and vegetables. The disadvantage of pure PCL as a packaging material is the lack of the antibacterial function. Photodynamic sterilization as a safe and effective antibacterial method is now the emerging means for food safety. Therefore, the porphyrinic metal–organic framework MOF-545 as a highly effective photosensitizer was incorporated with PCL to prepare a biodegradable antibacterial composite film. The incorporation of MOF-545 nanorods significantly enhanced the hydrophilicity and mechanical strength of the film while slightly decreasing the transparency. The PCL/MOF-545 (10%) film exhibited the strongest antibacterial activity under a white LED light. This film was used for packaging fresh-cut apples and effectively killed 96% of the microorganisms, also delaying the apples’ discoloration and water loss. The PCL/MOF-545 film showed great potential for the antibacterial packaging of fruits and vegetables.
