“…This could be related to the significantly higher presence of ashes in PO biomass (Table 1), which were not completely eliminated by the simplified extraction method (Table 2), thus yielding nanocrystals with lower cellulosic and hemicellulosic contents but a significant amount of additional compounds such as ashes. [38,39] On the other hand, as expected, CNC-BG showed major quantities of glucose and xylose, while other acid labile sugars like arabinose, typically present in the arabinoxylan structures even after the malting of the grains, [40] were seen to be removed after the extraction of the nanocrystals. In this case, the presence of a significant quantity of recalcitrant proteins was still observed after CNC purification (Table 2).…”

Novel and more sustainable sound absorbing materials are produced through the valorization of waste biomass sources by following circular economy principles. Cellulosic nanocrystals (CNC) were extracted from Posidonia oceanica dead leaves, spent barely grains, and kale stems using a simplified purification protocol. These nanocrystals are used to prepare cellulosic aerogels, evaluating the effect of three parameters, namely, concentration (0.5–4%), CaCl2 and poly(lactic acid) (PLA) incorporation (hybrid aerogels), on their sound absorption properties. Aerogels from 4% suspensions show the highest sound absorption, outperforming benchmark rockwool and polyester—two modern commonly‐used sound absorbers. Moreover, PLA coating also improves the sound absorption performance of the most aerogels. CNC from KS aerogels are selected as the optimum at both high (500–6000 Hz) and low (100–1500 Hz) frequency ranges. Overall, these results represent a new proof‐of‐concept of waste biomass conversion to high‐performance cellulosic aerogels that have excellent sound absorbing properties.

“…In addition, consumers are now eager to support food products that are aware of the sustainable living lifestyle [ 2 ]. Therefore, biocomposite packaging films have been widely applied on several food product types, using various biopolymers [ 3 ], rice [ 1 ], corn [ 4 ], soy protein isolate [ 5 ], gelatin [ 6 ], chitosan [ 7 ], polylactic acid [ 8 ], etc. However, the application of bio-based food packaging must ensure the safety and quality of food products [ 9 , 10 ].…”

“…The primary difficulties of the bio-based packaging film, such as low cost-efficiency and low degradation rate, have limited their implementation as food packaging [ 1 ]. At the same time, rice starch-based packaging film has been a promising alternative to biopolymer packaging due to its abundantly available nature, low cost, and good film-forming ability [ 14 , 15 ].…”

Dragon Fruit Peel Extract Enriched-Biocomposite Wrapping Film: Characterization and Application on Coconut Milk Candy

Bio-based film is an eco-friendly alternative to petroleum-based packaging film. The effects of biocomposite wrapping film enhanced with dragon fruit peel extract (0, 2% w/v, respectively) and currently used commercial packaging film (polypropylene; PP) on coconut milk caramels during storage (30 °C, 75% RH, nine days) were studied. Both 0% and 2% DPE-enriched biocomposite films were thicker and had higher water vapor permeability and solubility than the PP film but poorer mechanical characteristics. In addition, the 2% film possessed antioxidants and antioxidant ability. A FESEM micrograph revealed the rough surface and porous path of the biocomposite films. Over the storage time, the moisture content, water activity, and springiness of the coconut milk caramel candy wrapped in the PP and all DPE-enriched biocomposite films were not significantly altered. However, the lipid oxidation as the thiobarbituric acid reactive substance (TBARS) and hardness of all coconut caramels were significantly (p < 0.05) increased during storage. Furthermore, the hardness of coconut candy covered in the control (0% DPE) biocomposite film was more pronounced on day nine of storage. However, the changes in quality characteristics of the coconut candy wrapped in each film type need to be better established. The investigating factors influencing the quality deterioration of coconut milk candy should be further identified to mitigate their effects and extend the shelf-life of the coconut candy.

“…477,478 The application of rice starch has been widely investigated for the development of sustainable films. [479][480][481][482][483][484] Mangaraj et al 159 produced biodegradable films based on PLA/Rice starch (10% by weight) with the incorporation of two reagents (benzoyl peroxide and glycidyl methacrylate) by blown film extrusion. According to the obtained results, the T g of the film reduced from 65.26 to 60.46°C.…”

Polymers from Renewable Resources

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.
