Anise (Pimpinella anisum L.) is one of the most important annual herbs of the Apiaceae family, widely cultivated in southern Spain. Their seeds are highly valued for culinary uses and for producing quality essential oils widely used in food and beverage products, as well as for industry, medicinal, and cosmetics applications. This study investigates the seed yield and essential oil content within a set of 50 anise accessions from worldwide origin, as well as their composition by GC–MS and GC–FID analysis. Accessions showed significant differences in the agronomic parameters measured, including plant height (cm), seed yield (kg ha⁻¹), and the Harvest Index (%), with accessions PA_87 (Spain), PA_47 (Greece), and PA_21 (unknown origin) being the most performant. Essential oil (EO) content varied between 0.8% and 5.7% across different genotypes, resulting in EO production values ranging from 0.1 to 300 kg ha⁻¹. Trans-anethole was identified as the dominant terpene, comprising 84.4% to 94.4% of the content, followed by eugenol (1.4% to 5.5%) and α-muurolene (1.4% to 7.2%). PCA analysis identified five distinct groups and one outlier, influenced by minor terpenes. Indeed, there was a strong negative correlation between estragole and pseudoisoeugenyl 2-methylbutyrate. This study underscores the significance of minor terpenes, which play crucial roles in defining unique aniseed chemotypes, allowing for the selection of cultivars optimized for specific uses in food, cosmetics, and pharmaceuticals. Additionally, these findings emphasize the impact of cultivar genetics on agronomic traits and EO profiles, suggesting the need for further research to optimize plant growth and yield and EO quality.

Hemp is a high-yield crop traditionally cultivated for fiber used in products such as paper, textiles, ropes, and animal bedding, and more recently for sustainable applications in biofuels, insulation, and bioplastics. Beyond fiber, hemp is rich in phytochemicals. More than 500 compounds including cannabinoids, terpenes, phenolics, phytosterols, and tocopherols are accumulated in leaves, flowers, and seeds, which are typically considered waste products in the fiber industry. These compounds exhibit antioxidant, anti-inflammatory, neuroprotective, and antimicrobial properties, which have stimulated research into their pharmaceutical potential. However, hemp phytochemicals also find applications in other industrial sectors, including agrochemistry as natural insecticides, cosmetics for skin and hair care, and food and dietary supplements due to their associated health benefits. In light of this, the present review aims to give an overview of the available literature on the most common applications of hemp tissues, hemp extract, and purified hemp phytochemicals in agrochemical, cosmetic, and food sectors. This will be helpful to critically assess the current state of knowledge in this field and contribute to the ongoing debate over the natural and sustainable applications of hemp by-products.

Illite, a clay mineral, is used in diverse fields such as agriculture, cosmetics, and the food-related industry due to its many advantages, including biocompatibility, UV protection, antibacterial activity, high adsorption capacity for hazardous substances, and cost-effectiveness. However, its relatively large size, broad size distribution, and irregular morphology limit its broader applications. This study investigated the control of particle size and distribution during wet ball milling (WBM) using five media—acetone, ethanol, water, aqueous NaCl solution, and aqueous phosphoric acid solution—over milling times of 2–10 h. Prolonged milling progressively reduced particle size and narrowed the size distribution. Acetone and ethanol exhibited notably superior size-reduction performance compared with the aqueous systems, among which phosphoric acid solution showed the least effectiveness, likely attributed to variations in their physicochemical properties, including viscosity (η) and surface tension (σ), and in their interfacial interactions with illite. Optimal milling in acetone for 10 h resulted in the smallest particles (~700 nm), the narrowest distribution, the largest specific surface area, and the highest moisture retention. Overall, these findings demonstrate that the physicochemical properties of the milling medium, which govern WBM efficiency through fluid dynamics and particle–medium interactions, thereby determine the size and distribution of milled particles.

The cosmetic industry is undergoing a deep transformation driven by rapid innovation, evolving consumer expectations, and increasing demands for sustainability. Formulators are required to design products that combine functional efficacy, stability, and appealing sensory properties while adopting environmentally responsible strategies. Traditional empirical and sensory-based approaches, though valuable, are often limited by high costs, time, subjectivity and lack of reproducibility. In this context, instrumental techniques provide an objective and predictive means to optimize product performance. Rheology, texture analysis, and tribology offer complementary insights into the structure, mechanical behavior, and interfacial phenomena of cosmetic formulations, all of which are closely linked to application behavior and sensory perception. Their integration enables a quantitative correlation between formulation composition, process conditions, and tactile performance. This review critically examines recent advances in the integrated use of rheology, texture analysis and tribology in cosmetic science, highlighting their role in sensory prediction, stability assessment, scale-up and eco-design. Together, these instrumental approaches support a more data-driven and innovation-oriented formulation paradigm, enabling database development and predictive modeling. Future research should prioritize database expansion, in vivo validation and machine learning integration to further improve sensory prediction and accelerate the design of advanced cosmetic formulations.

Roses held profound cultural and economic significance in ancient Greece and Rome, yet comprehensive documentation of their species diversity, cultivation practices, and horticultural innovations remains fragmented across archaeological, iconographic, and textual sources. This multidisciplinary study synthesizes evidence from classical texts, archaeological remains including recently identified rose stem fragments from Oplontis, and iconographic materials—including frescoes, coins, and mosaics—to reconstruct the horticultural systems and cultural landscape of roses in classical antiquity. Analysis of literary sources, particularly Theophrastus’s fourth-century BCE taxonomic descriptions, reveals systematic cultivation of diverse rose varieties with flowers ranging from white to deep crimson, including yellow variants, characterized by morphologies from simple to double forms and valued for fragrance intensity and re-blooming capacity. Archaeological evidence from sites such as Paestum, Pompeii, and Oplontis, including pollen samples, preserved wood fragments with diagnostic prickle patterns, and fresco representations, documents commercial rose production and specialized cultivation techniques that demonstrate significantly greater morphological diversity than textual sources alone indicate. Field research and collection documentation establish the origins of Mediterranean rose cultivation, while iconographic analysis identifies roses in religious ceremonies, festivals, and daily life contexts. Textual sources provide detailed propagation methods, seasonal management practices, and evidence of Mediterranean hybridization events, alongside extensive documentation of medicinal and cosmetic applications. Economic analysis reveals specialized trade networks, commercial production centers, and diverse applications in perfumery, garland making, and pharmaceutical industries. This research establishes that Greek and Roman civilizations developed sophisticated rose cultivation systems integrating botanical selection, horticultural innovation, and cultural symbolism that directly influenced medieval and Renaissance practices and informed modern trait categorization systems. These findings demonstrate the foundational role of classical antiquity in European rose heritage, revealing how ancient horticultural knowledge, species diversification through hybridization, and cultivation techniques created an unbroken transmission that shaped contemporary rose industries and established conservation priorities for this horticultural heritage.

In order to improve the utilization of alkali lignin (AL) as an effective component for ultraviolet (UV) shielding, demethylation and acetylation modification were carried out to improve the UV absorption performance of lignin. Then, lignin-based sunscreens were successfully prepared by mixing the modified lignin and commercial cream without UV shielding ingredients. The modified alkali lignin was comprehensively characterized in terms of its molecular weight, functional groups and structural properties by GPC, UV spectroscopy and ³¹P NMR. The results showed that the Mw of all three lignin feedstocks (AL, AL_MeOH and AL_Acetone) was decreased with prolonged demethylation time. Compared to the original feedstock, demethylated AL had a darker color and improved UV absorption performance due to the increased phenolic hydroxyl content (approximately 4.35 mmol/g). ³¹P-NMR spectra showed that the guaiacyl phenolic hydroxyl content decreased rapidly after acetylation, causing the sample color to become lighter. Among all lignin-based sunscreens, DAL_Acetone achieved the highest SPF value of 11.23, a 69.4% increase over its pre-reaction level and a 7.58-fold enhancement compared to the original lignin. In summary, this study opens a promising avenue for repurposing industrial lignin as a sustainable biomaterial in high-value sectors like UV-blocking agents and cosmetic formulations. Full article

Tyrosinase (EC 1.14.18.1) is a binuclear copper enzyme responsible for the rate-limiting steps of melanogenesis, catalyzing the hydroxylation of L-tyrosine and oxidation of L-DOPA into o-quinones that polymerize melanin. Beyond its physiological role in pigmentation, tyrosinase is also implicated in food browning and oxidative stress–related disorders, making it a key target in cosmetic, food, and biomedical industries. This systematic review, conducted following PRISMA guidelines, aimed to identify and analyze microbial metabolites with tyrosinase inhibitory potential as sustainable alternatives to conventional inhibitors such as hydroquinone and kojic acid. Literature searches in Scopus and Web of Science (March 2025) yielded 156 records; after screening and applying inclusion criteria, 11 studies were retained for analysis. The inhibitors identified include indole derivatives, phenolic acids, peptides, and triterpenoids, mainly produced by fungi (e.g., Ganoderma lucidum, Trichoderma sp.), actinobacteria (Streptomyces, Massilia), and microalgae (Spirulina, Synechococcus). Reported IC₅₀ values ranged from micromolar to milli-molar levels, with methyl lucidenate F (32.23 µM) and p-coumaric acid (52.71 mM). Mechanisms involved competitive and non-competitive inhibition, as well as gene-level regulation. However, methodological heterogeneity, the predominance of mushroom tyrosinase assays, and limited human enzyme validation constrain translational relevance. Computational modeling, site-directed mutagenesis, and molecular dynamics are proposed to overcome these limitations. Overall, microbial metabolites exhibit promising efficacy, stability, and biocompatibility, positioning them as emerging preclinical candidates for the development of safer and more sustainable tyrosinase inhibitors.

Numerous sectors of the food processing and oleochemical industries require oils with specific physicochemical properties. Fruit processing generates substantial waste potentially containing valuable raw materials for oil extraction. The significant volumes of apples and cherries processed in Poland prompted an assessment of their seeds’ suitability as oil sources. Seed dry matter, protein, and oil content were determined. The extracted oils were analyzed for acid value (AV), peroxide value (PV), oxidative stability, fatty acid composition, and sterol and tocopherol content. The predominant higher fatty acids identified in the sour cherry and sweet cherry kernel oils were linoleic acid (C18:2, n-6), with mean concentrations of 45.82% and 29.23%, respectively, and oleic acid (C18:1, n-9), accounting for 41.54% and 46.59%, respectively. Additional fatty acids detected included palmitic acid C16:0 (6.23% and 5.91%), palmitoleic acid C16:1, n-7 (0.29%), stearic acid C18:0 (1.36% and 3.11%), arachidic acid C20:0 (1.13%), α-eleostearic acid C18:3 (5.07% and 9.48%), and α-linolenic acid C18:3, n-3 (4.09%). Given the substantial proportion of the oil fraction containing numerous potentially biologically active compounds, including nutritionally valuable fatty acids, tocopherols, and phytosterols, apple, sour cherry, and sweet cherry seeds demonstrate considerable potential as raw materials for applications in the food, pharmaceutical, and cosmetics industries.

Olive pomace (OP), a by-product of olive oil production, is a sustainable resource rich in bioactive compounds with potential applications in cosmetics and pharmaceuticals. This study investigates the protective effects of olive pomace juice (OPJ) against H₂O₂-induced neuronal damage and LPS-induced inflammatory responses in HT22 and BV2 cells, respectively. OPJ suppressed H₂O₂-induced cell death and exerted anti-apoptotic effects by reducing the BAX/BCL2 ratio and caspase-3 cleavage. OPJ also mitigated neurodegenerative hallmarks by decreasing amyloid fibrils formation and inhibiting β-secretase and acetylcholinesterase (AChE) activity. Mechanistically, OPJ enhanced antioxidant response by upregulating Nrf2 and its downstream molecule HO-1, along with increasing mRNA levels of antioxidant enzymes, including catalase, SOD1, and GPx. OPJ further activated AMPKα–SIRT1–PGC1α signaling and CREB–BDNF–TrkB signaling, suggesting modulation of key antioxidant, anti-apoptotic, and neurotrophic pathways. In BV2 cells, OPJ downregulated pro-inflammatory cytokines (IL-6 and IL-1β) and decreased iNOS and COX-2 expression through suppression of NF-κB and MAPK signaling pathways. HPLC analysis identified hydroxytyrosol (10.92%) as the major active compound in OPJ, which compared with tyrosol (2.18%), and hydroxytyrosol exhibited greater neuroprotective and anti-inflammatory effects than tyrosol. This study highlights the potential of OPJ and its major compound, hydroxytyrosol, as functional agents for mitigating neurodegeneration-related cellular response, supporting its application in the food and pharmaceutical industries.

Sustainable strategies for revalorizing food industry by-products are increasingly relevant in the development of modern experimental dermato-cosmetic formulations. In this study, two semisolid cosmetic creams (R10 and EM-R10) were designed using recycled palm oil—physically purified after intensive frying—as the lipid phase. The recycled oil was incorporated strictly within a controlled experimental framework and does not imply cosmetic-grade regulatory compliance. The formulations incorporated distinct bioactive profiles: R10 combined apricot and pineapple extracts with lime essential oil, while EM-R10 integrated fir bud and green tea extracts alongside the same essential oil. Both preparations contained Fragard as a preservative and niacinamide and panthenol as vitaminic components. The physicochemical properties of the formulations were assessed through rheology, confocal microscopy, ATR-FTIR, SEM, DSC, and contact angle measurements. Antimicrobial activity was evaluated against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans using disk diffusion and broth microdilution assays. The results demonstrate that, despite partial thermal degradation, recycled palm oil retains modified structural features that influence formulation-related properties relevant to topical systems. EM-R10 showed superior spreadability, adhesion, stability, and diffusion-related performance, as well as improved antimicrobial activity, within the investigated experimental conditions, highlighting recycled palm oil as a promising sustainable lipid phase for experimental dermato-cosmetic formulations, pending further purification, toxicological evaluation, and regulatory compliance assessment.

We systematically analyze the advantages, limitations, economic and environmental trade-offs of each production route, and highlight recent innovations in bioavailability enhancement and metabolic engineering. This review aims to provide a holistic theoretical and technical framework for accelerating curcumin’s sustainable development and commercialization in high-value products. Full article

Bee-derived products such as apitoxin, royal jelly, propolis, bee pollen, and honey are increasingly being used as part of cosmetic products because all of them contain a large number of bioactive compounds with antioxidant, anti-inflammatory, antimicrobial, and regenerative properties, which enable them to be used for therapeutic purposes. The aim of this investigation was to assess the performance of an automated growth-based system in order to make a quantitative examination of the total aerobic viable counts in bee-derived personal care products using NF-TVC vials that contained a nutrient-based medium with dextrose as the carbon source. According to USP general chapter <1223>, pivotal validation criteria such as linearity, equivalence of results, operative range, precision, accuracy, ruggedness, limit of quantification, and limit of detection have demonstrated that the automated system can be used for a reliable total aerobic viable count. Moreover, the actual research demonstrated that polysorbates efficiently block the antimicrobiological potential of bioactive compounds, such as phenols, flavonoids, enzymes, peptides, and fatty acids, which naturally occur in apitoxin, royal jelly, propolis, bee pollen, and honey, allowing for efficient microorganism recovery from the bee-made products tested. Therefore, this AGBS could be applied efficiently within the cosmetic industry to assess the total aerobic viable count in bee-derived products such as capillary treatments, toothpaste, and anti-aging cream, affording several benefits associated with faster product release into the market.

The European chestnut (Castanea sativa Mill.) industry generates substantial amounts of underutilized biomass, including shells, leaves, and spiny burs. Distinguishing itself from existing literature, this review presents a novel, integrated life-science analysis that redefines these by-products as a complementary ‘bioactive triad’, ranging from metabolic regulators to anti-virulence agents, rather than interchangeable sources of polyphenols. Although traditionally discarded, these by-products are rich sources of polyphenols, ellagitannins, and flavonoids, with promising potential for nutraceutical, cosmetic, and pharmaceutical applications. This review examines recent advances in the valorization of chestnut by-products, focusing on extraction strategies, chemical profiles, and biological activities. Shell valorization has increasingly shifted toward green extraction technologies, such as subcritical water extraction and deep eutectic solvents, which strongly influence bioactive recovery and composition. Chestnut leaves emerge as a sustainable resource enriched in hydrolysable tannins with anti-inflammatory and quorum sensing-inhibitory properties, particularly relevant for dermatological applications. Spiny burs, often the most phenolic-rich fraction, display marked antioxidant activity and the ability to potentiate conventional antibiotics against pathogens such as Helicobacter pylori. Despite these promising features, major challenges remain, including cultivar-dependent chemical variability, the predominance of in vitro evidence, and safety concerns related to the accumulation of potentially toxic elements. Overall, while chestnut by-products represent valuable resources within circular bioeconomy frameworks, their successful industrial and practical translation will require standardized extraction protocols, robust bioavailability assessments, and well-designed in vivo and clinical studies to ensure safety and efficacy.
