Consumer Perception and Behavior for Sustainable Market Success
No full textThe bioeconomy is one of the most significant economic sectors in the global economy, and numerous biobased products and services have been developed in recent years. Most assessments in the field of biobased products focus on process development, technologies, and sustainability assessment. In addition to the most common focus, one of the key areas is the understanding of consumer trends, which are a critical factor in biobased products. These trends are driven by psychological, economic, social, and cultural factors, and their assessment must be developed considering factors like gender, age, income, regional culture, and labeling. Developing effective strategies to introduce biobased products into the market is essential for advancing sustainable development and must be given due emphasis
Impact of UV-C Exposure on the Chemical Profile and Functional Properties of Grape Seed Oil
No full textThe impact of UV-C radiation (25.0 mJ/cm², 253 nm) on grape seed oil was studied relative to varying exposure times (0, 30, and 60 min) to assess structural and biological changes. Gas chromatography-mass spectrometric analysis identified major chemical constituents such as n-hexadecenoic acid, oleic acid, and 2,6-bis(3,4-methylene dioxyphenyl)-3,7-dioxa bicyclo (3.3.0) octane, with trace amounts of other compounds that notably increasing after 60 min of exposure. Antimicrobial activity against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, and Candida albicans increased progressively with exposure time, with the 60-min treated oil showing the strongest inhibitory zones, comparable to standard drugs. However, no significant effects were observed against Penicillium glabrum and only weak inhibition toward Salmonella typhi (10±0.4 mm). Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values were markedly reduced after UV-C treatment, highlighting enhanced antimicrobial potency. Furthermore, applying 75% of the MIC from 60-min treated oil markedly elevated its anti-hemolytic activity. Extended UV-C exposure also enhanced anti-inflammatory and anti-Alzheimer effects, suggesting improved therapeutic potential. Overall, results indicated that controlled UV-C irradiation substantially modifies the chemical profile and boosts the biological activities of grape seed oil. Further investigation is required to optimize exposure duration and elucidate the underlying mechanisms
Wildfire Management: Canada’s Carbon Opportunity and a Lesson for All
No full textCanada’s recent wildfires have released well over half a gigaton of carbon dioxide in a single season, which on par with the annual emissions of Japan or Germany. Removing this volume through engineered carbon capture would cost more than one trillion dollars, yet only a fraction of that is spent on wildfire suppression and sustainable mitigation. Proactive forest management, which includes thinning, harvesting, and putting fuel wood to productive use, offers a far more cost-effective path, reducing fire intensity while creating low-carbon products and rural jobs. Redirecting even a small share of carbon-offset spending toward such projects could fund lasting prevention. For both Canada and elsewhere, investing in prevention is sound climate policy and an economic imperative

Humins: Still-unknown Antagonists in Polysaccharides Valorisation
No full textAmong the primary objectives of modern biorefineries is the production of furfural, hydroxymethyl furfural, and their derivatives, which are key compounds for the synthesis of widely used fine chemicals, including plastics and other everyday materials. However, the industrial development of these processes is hindered by the formation of unwanted by-products, most notably humins. Humins are highly cross-linked macromolecules of complex nature with limited technological applications. This editorial offers a brief overview of the “humin issue”, discussing the challenges posed by these materials from an analytical perspective. Despite considerable efforts towards their characterization, the structure of these materials remains largely unresolved, representing an ongoing challenge for green chemistry and the optimization of biorefinery processes

No full textLignocellulosic biomass provides a sustainable substitute for fossil resources in energy, materials, and products. This editorial highlights important developments in biotechnological and bioprocessing methods while analyzing the present pace and trajectory of lignocellulosic valorization. Despite encouraging developments, there are still many obstacles to widespread adoption, such as sociopolitical acceptance, economic viability, and technical complexity. To overcome these obstacles and to hasten the necessary shift to a genuinely sustainable bioeconomy, there is a vital need for integrated biorefinery approaches, sophisticated feedstock engineering, and encouraging policy frameworks. This editorial emphasizes how urgent it is to work together in order to fully utilize lignocellulosic resources
Effect of Gelatin/Xanthan Gum Ratios on Jackfruit Leaf Extract Nanoemulsion Gel Stability and Properties
No full textNanoemulsions were formulated as hydrogels, incorporating extract from jackfruit leaf (JLE) and consisting of a blend of xanthan gum and fish gelatin (XAN-GEL). Utilizing the spontaneous emulsification technique, single xanthan gum (XAN), single fish gelatin (GEL), and XAN-GEL blends were hydrated at a mass ratio (0.5 to 2.5% w/v) and were prepared and subsequently assessed for various parameters such as droplet size, polydispersity index (PDI), zeta potential, colloidal stability, and viscosity. Additionally, plain nanoemulsion (NE) and carbomer were synthesized as control samples for comparative analysis. The droplet size, PDI, and zeta potential values of the developed nanoemulsion and gelled nanoemulsion fell within the ranges of 131 to 223 nm, 0.23 to 0.33, and -27.3 to -47.3 mV, respectively. Notably, all formulations exhibited stability except for the lower amount of XAN ratio blends at 1.0% (MD) and 0.5% (ME). Furthermore, all stable nanoemulsion gels demonstrated shear thinning behavior, and the highest amount of XAN ratio blends at 2.0% (MA) enhanced the viscosity of the nanoemulsion by fine tuning the rheological characteristics of the targeted gelled nanoemulsion suitable for future topical drug delivery application
Application of Synthetic-based Furniture Varnish to Various Wood Species: Comparison of Color Parameters
No full textSynthetic-based furniture varnish (colorless and glossy) was applied in two coats using a brush to the following wood types: lemon (Citrus limon (L.) Burm.), black pine (Pinus nigra Arnold), kotibé (Nesogordonia papaverifera), iroko (Milicia excelsa Welw. C.C. Berg), and loquat (Eriobotrya japonica Lindl.). The color parameters [b*, ho, L*, a*, and C*, ∆a*, ∆L*, ∆C*, ∆H*, ∆b*, and ∆E*] of the varnished and unvarnished surfaces were compared. The analysis of variance results for all color parameters revealed significant effects for wood type, varnish application, and their interaction. When the ∆E* values derived from color formulas were sorted from the lowest to the highest, they were ordered as follows: lemon, black pine, kotibé, loquat, and iroko. After varnish application, decreases in L* values were observed across all wood types, while increases in b* and C* values were detected. In black pine wood, the a* and ho values increased. Additionally, for iroko, loquat, and kotibé woods, there was an increase in the a* parameter, while ho values decreased for these wood types. Overall, the varnish application resulted in color changes in the wood materials.
Application of Symbolic Language and Pattern Innovation of Chaoshan Peach Cake Mold in Paper Packaging Design
No full textTo explore the symbolic language of the Chaoshan peach cake mold and its innovative applications in modern design, the material form and cultural connotations of the mold patterns were analyzed from a semiotic perspective. Through a symbolic language of the primary pattern elements, the essence of the traditional culture they embody was revealed. Building on this analysis, the generative rules of shape grammar were applied to creatively reinterpret and recombine these traditional pattern elements, resulting in a set of innovative designs that retain the essence of traditional culture while incorporating modern design aesthetics. Furthermore, these innovative patterns were implemented in paper packaging design, and their effectiveness was validated through product evaluation. Through an in-depth exploration and innovative application of the symbolic language of the Chaoshan peach cake mold, a successful fusion of traditional cultural symbols and contemporary design concepts was achieved. This approach provides a new pathway for the inheritance and innovation of Chaoshan peach cake mold culture and offers insights into the modern transformation of other traditional cultures
Chemical Control on Contamination Caused by Three Molds in Edible Mushroom Production
No full textThis experiment aimed to test the effectiveness of four antifungal chemicals in controlling mold contamination in edible mushroom production. The antifungal chemicals were terbinafine hydrochloride, prochloraz, azoxystrobin, and sodium dichloroisocyanurate. The inhibitory effects of the chemicals were evaluated for inhibition on Cladosporium sp., Aspergillus niger, and Neurospora sp. The mycelia of the three molds and Morchella sextelata were cultured individually and co-cultured on plates with different concentrations of these chemicals, and then the mycelial growth was observed. By comparing the growth areas under the same conditions, the appropriate concentrations of each chemical were determined. The results indicated that terbinafine hydrochloride and prochloraz significantly inhibited the mycelial growth of all three mold species at certain concentrations, whereas their impact on the mycelial growth of M. sextelata was not significant. These results suggest that these two chemicals are effective in controlling the mycelial growth of the three molds, potentially increasing the yield and quality of M. sextelata and reducing mold contamination during storage and transportation.
