The consumption of animal- and plant-based protein food is increasing as the world population grows. Alternative protein sources that are nutritious, safe and sustainable are needed. There is a growing research interest in integrating wheat-based staple foods, such as pasta, with new ingredients that could also provide nutritional and health benefits. Despite their unquestionable nutritional value, new pasta formulations need to be evaluated in terms of technological/sensory quality. In this study, we assessed the quality and flavour of traditional egg pasta fortified with two alternative protein sources: hazelnut flour and cricket powder. It is known that a quality pasta tends to lose fewer solids during cooking. In parallel with classical evaluation of cooking and sensory characteristics, proton nuclear magnetic resonance (¹H NMR) spectroscopy of the metabolites released during the cooking process and volatile fingerprint analysis with quartz microbalance (QMB) electronic nose (E-nose) were performed. These approaches showed results complementary to those obtained from classical quality and sensory analyses, thus demonstrating the potential of ¹H NMR and E-nose in pasta quality assessment. Overall, the pasta fortification with cricket powder and hazelnut flour affected the matrix mobility by modulating the release of chemical components into the water during cooking and overcooking processes; moreover, it significantly altered the pasta sensory profile in terms of aroma and texture. This finding highlights the complexity of balancing technological improvement with sensory appeal in food product development. Full article

The growing demand for health-promoting food products has led to increased efforts to develop formulations enriched with probiotics and dietary fiber (DF). While traditional fermented foods remain widely recognized sources of probiotics, there is a pressing need to innovate novel, nutritious, and high-quality alternatives that also incorporate additional functional ingredients. In the context of sustainable consumption and health-conscious dietary trends, fruit and berry pomace has emerged as a promising source of DF with prebiotic potential, supporting the growth and activity of beneficial gut microorganisms. A growing body of research emphasizes the potential of pomace valorization, showcasing its relevance in the development of value-added food products. This review explores the key features and selection principles for probiotic strains, particularly those from the former group of Lactobacillus species, alongside opportunities for combining probiotics with fruit and berry pomace in functional food matrices. Special attention is given to the physiological and technological attributes of DF derived from pomace, which are critical for their successful application in food systems and their potential synergistic effects with probiotics. Although numerous probiotic-enriched products are currently available, DF remains an underutilized component in many of these formulations. Research has predominantly focused on dairy-based applications; however, the increasing demand for plant-based diets calls for a shift towards non-dairy alternatives. Looking forward, future innovations should prioritize the integration of probiotics and pomace-derived DF as symbiotic systems into plant-based food products, with an emphasis on their dual roles as nutritional enhancers and potential prebiotics.

The study aimed to produce semolina pasta enriched with walnut or hazelnut oil cake and to investigate its nutritional and technological properties. The pasta was prepared by substituting 10% of semolina with walnut or hazelnut oil cakes. The chemical composition, antioxidant properties, and culinary characteristics of the pasta were determined. Additionally, the texture and color of uncooked and cooked pasta were examined using instrumental techniques. The enriched pastas showed higher protein, fat, ash, and dietary fiber contents compared to standard pasta (SP). Walnut oil cake pasta (WOCP) had the highest protein content, amounting to 15.8 g/100 g dry weight (d.w.), while hazelnut oil cake pasta (HOCP) had the highest dietary fiber content (6.75 g/100 g d.w.). Moreover, the enriched pastas showed significantly higher antioxidant potential and total phenolic content, both before and after cooking. The total phenolic content (TPC) of cooked pasta ranged from 88.85 mg GAE/100 g d.w. (SP) to 145.48 mg GAE/100 g d.w. (WOCP). Compared to SP, the developed pastas required cooking times of 2–3 min longer and showed higher water absorption, accompanied by increased cooking losses. They were characterized by a specific, dark color and showed reduced hardness and lower elasticity after cooking compared to SP. Pasting properties further suggested that starch swelling was restricted by the nut oil cakes. Overall, incorporating walnut and hazelnut oil cakes enhanced the nutritional profile and imparted notable health-promoting attributes to the pasta, underscoring the potential of these by-products as functional ingredients in pasta formulations.

Background: Type 2 diabetes (T2D) has become a serious global public health concern. Liubao tea (LBT) has demonstrated beneficial effects on gut microbiota and glucose-lipid metabolism, holding promising therapeutic potential for T2D; however, its underlying mechanisms remain unclear. This study aims to elucidate the potential mechanisms of Liubao tea extract (LBTE) against T2D. Methods: LC-MS technology was used to identify the chemical components of LBTE and combined with network pharmacology and molecular docking to screen its potential active ingredients and targets for improving T2D. Therapeutic efficacy was assessed in high-fat diet/streptozotocin (HFD/STZ)-induced diabetic mice via serum biochemical analyses and histopathological examinations. Serum metabolomics, 16S rRNA sequencing, quantification of short-chain fatty acids (SCFAs), quantitative real-time PCR (qPCR), and antibiotic-treated pseudo-germ-free models were employed to elucidate the underlying mechanisms. Results: LBTE effectively reduced blood glucose levels and improved lipid metabolism, primarily by promoting hepatic glycogen synthesis and suppressing glycerophospholipid synthesis. LBTE also alleviated hepatic inflammation by modulating inflammatory cytokine expression. Additionally, LBTE reshaped the gut microbiota profiles by decreasing harmful bacteria and increasing SCFA-producing bacteria, resulting in elevated fecal SCFAs. SCFAs contributed to improving hepatic metabolism and inflammation, enhancing intestinal barrier function. Notably, these effects were abolished by antibiotic-induced microbiota depletion, confirming the microbiota-dependent mechanism of LBTE. Quercetin, luteolin, genistein, and kaempferol were considered as potential active ingredients contributing to the antidiabetic effects of LBTE. Conclusions: These findings provide novel perspectives on the viability of LBTE as a complementary strategy for T2D prevention and management. Full article

As a highly disabling chronic inflammatory disease, rheumatoid arthritis (RA) necessitates novel interventions. Liupao tea is a traditional Chinese dark tea known for its favorable anti-inflammatory properties. This study aims to elucidate the active ingredients and action mechanisms underlying the therapeutic effects of Liupao tea extract (LPTE) in RA. LPTE was preliminarily characterized by LC-MS technology. Network pharmacology and molecular docking predicted anti-RA compounds, targets, and pathways, with key compounds identified using chemical standards. The effect of LPTE on the collagen-induced arthritis mouse model was evaluated through serum biochemical analysis, micro-CT imaging, and histopathological analyses. Integrated serum metabolomics, 16S rRNA sequencing, MetOrigin analysis, SCFA metabolomics, and quantitative real-time PCR elucidated gut–joint axis mechanisms. LPTE effectively attenuated RA symptoms by reducing bone destruction and joint inflammation. Notably, LPTE reshaped gut microbiota by enriching key families such as Monoglobaceae, Eggerthellaceae, and Desulfovibrionaceae, thereby promoting SCFA production. Increased SCFA levels enhanced intestinal barrier integrity and exerted joint-protective and anti-inflammatory effects by upregulating tight junction proteins and activating SCFA receptors. LPTE also modulated arachidonic acid metabolism by affecting key genes such as Alox5, Ptgs2, and Cbr1. These effects collectively reduced the levels of pro-inflammatory cytokines and increased the expression of anti-inflammatory cytokines in joints. Additionally, quercetin, luteolin, ellagic acid, and kaempferol were identified as major anti-RA bioactive compounds in LPTE. Taken together, this study provides preliminary evidence that LPTE mitigates RA by regulating the gut–joint axis mediated via fatty acid metabolism. Full article

Background/Objectives: The melt-spinning process has seen limited application in the pharmaceutical industry. However, nano- and microfibrous structures show significant potential for novel drug delivery systems, due to their high specific surface area. To facilitate broader adoption in pharmaceutical technology, critical parameters influencing fiber quality and yield must be investigated. In this study, we aimed to develop an isomalt-based microfibrous carrier system for active pharmaceutical ingredients. Methods: The effects of different isomalt compositions—specifically, varying ratios of GPS (6-O-α-d-glucopyranosyl-d-sorbitol) and GPM (1-O-α-d-glucopyranosyl-d-mannitol)—as well as key process parameters, were systematically investigated to optimize fiber formation. The prepared fibers underwent different treatments. Morphological changes were monitored with a microscope, and microstructural changes were studied using a differential scanning calorimeter and X-ray diffractometer. The macroscopic behavior of the fibers was evaluated by image analysis under monitored conditions. Results: Statistical analysis was used to determine the optimal setting to produce isomalt-based fibers. We found that storage over ethanol vapor has a positive effect on the stability of the fibers. We successfully prepared ibuprofen sodium-containing fibers that remained stable after alcohol treatment and enabled drug release within 15 s. Conclusions: It was found that the applied GPS:GPM isomalt ratio significantly influenced fiber formation and that storage over ethanol positively influenced the processability and stability of the fibrous structure. An isomalt-based microfibrous system with advantageous physicochemical and structural properties was successfully developed as a potential drug carrier. The system is also resistant to the destructive effects of ambient humidity, enabling preparation of suitable dosage forms. Full article

Stevia rebaudiana leaves and extracts need to be promptly dried after harvest to prevent microbial activity and preserve their bioactive compounds, including glycosides, flavonoids, and essential oils. Effective drying also reduces moisture and volume, which lowers packaging, storage, and transportation costs. Therefore, innovative drying methods are necessary to maintain stevia’s physicochemical, sensory, and nutritional properties for functional food formulations. This review evaluates various drying technologies for stevia leaves and extracts, including convective hot air, infrared, vacuum, microwave, freeze, and shade drying, and their impacts on product quality and energy efficiency. It also explores the growing applications of dried and extracted stevia in food products. By comparing different drying methods and highlighting the benefits of stevia in these food formulations, this investigation aims to identify future research directions and optimization strategies for utilizing stevia as a natural sweetener and functional ingredient. Convective hot air drying at higher temperatures was found to be the most energy-efficient, though several studies have reported moderate degradation of key bioactive compounds such as stevioside and rebaudioside A, particularly at elevated temperatures and extended drying times. Infrared drying enhanced antimicrobial activity but resulted in lower levels of polyphenols and antioxidants. Vacuum drying effectively preserved anti-inflammatory compounds like flavonoids. Microwave drying presented strong protection of antioxidant activity and superior particle morphology. Freeze drying, while less energy-efficient, was the most effective at retaining antioxidants, polyphenols, and volatile compounds. Shade drying, though time-consuming, maintained high levels of polyphenols, flavonoids, and essential oils. Advanced techniques like spray drying and electrospraying have been reported to enhance the sensory qualities and stability of stevia extracts, making them ideal for food applications such as dairy and baked products, confectionery, syrups, snacks, jams, preserves, and meat products. Overall, stevia not only serves as a natural, zero-calorie sweetener but also contributes to improved health benefits and product quality in these diverse food formulations. Full article

Allergic contact dermatitis is one of the most common adverse events associated with cosmetic use. Accordingly, assessment of skin sensitisation hazard is required for safety evaluation of cosmetic ingredients. The transition to the use of alternative methods for testing has made skin sensitisation an intense field in the past decades. The first alternative methods have been in place for almost a decade, but none as stand-alone replacement for the reference murine Local Lymph Node Assay (LLNA). While strategies to combine data from several methods are being evaluated and refined, individual methods face technical limitations. These include issues related to their applicability to highly lipophilic substances and the lack of reliable potency estimation, which remain important obstacles to their widespread adoption as replacement for animal methods. The unique characteristics of in vitro skin models represented an attractive alternative, potentially overcoming these limitations and offering a more physiologically relevant environment for the assessment of the response in keratinocytes and dendritic cells. In this review, we recapitulate how reconstructed human skin models have been used as platforms for skin sensitisation testing, including the latest approaches using organ-on-a-chip and microfluidic technologies, aimed to develop next-generation organotypic skin models with increased complexity and monitoring capabilities.

Several potential alternatives to develop analog rice, including sago and corn flour, can be developed with the addition of moringa leaf powder due to its high nutritional composition and bioactive compounds, particularly high protein, iron, phytosterols, and flavonoids, which are suitable for breastfeeding women. However, as a new product, besides considering its nutritional value, developing the preferred and acceptable formulation of analog rice remains challenging. This research aims to gain the best formulation and investigate the physicochemical and sensory properties. Three formulations of analog rice were applied in this study utilizing extrusion technology, comprising sago, corn flour, and moringa leaf powder in ratio variations as follows: A, 60:37:3; B, 70:25:5; C, 80:10:10. Overall, the analog rice produced had a green color, a sticky texture, a distinct moringa aroma, and a slightly bitter taste, with Formulation C being most preferred (overall organoleptic value of 2.5, categorized as neutral), containing 6.22 ± 0.83% moisture, 1.04 ± 0.07% ash, 4.08 ± 0.17% protein, 0.46 ± 0.09% fat, 88.21 ± 0.59% carbohydrate, 3.42 ± 1.54% crude fiber, 382.62 ± 3.75 Kcal, 40.12 ± 13.38 ppm iron, 1.09 ± 0.05% sitosterol, 1.16 ± 0.03% stigmasterol, and 0.19 ± 0.07% flavonoid levels. The analog rice provides high energy and lactation-supporting bioactive compounds (iron, phytosterols, and flavonoids), demonstrating potential as a sustainable dietary intervention. This study offers a novel approach through the development of extruded analog rice, which transforms local ingredients into a functional food targeting maternal nutritional gaps by synergizing sago, corn flour, and moringa leaf powder.

The genera Parageobacillus and Geobacillus comprise thermophilic, spore-forming bacteria. The extraordinary heat resistance of their spores, together with their ability to form biofilms and produce thermostable enzymes, makes them a relevant cause of spoilage in shelf-stable, heat-treated products like dairy and canned foods. However, these same biological traits offer valuable opportunities for the food industry. In this context, the purpose of this review is to describe the challenges posed by (Para)Geobacillus spp. as food spoilage agents, while also highlighting their existing and prospective applications in the food industry. In terms of food safety, G. stearothermophilus spores are used as biological indicators in commercially available tests to detect antibiotic residues in food within a few hours. Additionally, (Para)Geobacillus can be exploited for the fermentation of agri-food residues to produce high-value compounds such as biofuels, food ingredients and technological adjuvants, and compost. Their thermostable enzymes—such as amylases, xylanases, L-arabinose isomerases, β-galactosidases, lipases, proteases, and L-asparaginases—have potential applications in food processing and ingredient production. However, several challenges persist, including limited knowledge on genetic diversity, physiology, and metabolism, as well as low yields of biomass and target compounds. These issues reinforce the need for further studies to unlock their full potential. Full article

Seeds of Cucurbitaceae crops represent a promising yet underexplored source of bioactive compounds with potential applications beyond nutrition, particularly in the cosmetics industry. This review examines the seeds of Citrullus lanatus (watermelon), Cucumis melo (melon), and Cucurbita pepo (pumpkin), focusing on their biochemical composition and evaluating their functional value in natural cosmetic development.

Sociotechnical systems (STSs) are generally assumed to be systems that incorporate humans and technology, strongly depending on a sustainable equilibrium between the following nondeterministic social context ingredients: social structures, roles, and rights, as well as the designers’ Holy Grail, the deterministic nature of the underlying technical system. The fact that the relevant social concepts are more mature than the supporting technologies qualifies the digital transformation of sociotechnical systems as a reengineering rather than an engineering endeavor. Preserving the social mission throughout the digital transformation process in varying social contexts is mandatory, making the digital twins (DT) methodology application a contemporary research hotspot. In this research, we combined continuous transformation STS theory principles, an observer-based system-of-sociotechnical-systems (SoSTS) architecture model, and digital twinning methods to address common STS context representation challenges. Additionally, based on model-driven systems engineering methodology and meta-object-facility principles, the research specifies the universal meta-concepts and meta-modeling templates, supporting the creation of arbitrary sociotechnical systems’ external context digital twins. Due to the inherent diversity, significantly influenced by geopolitical, economic, and cultural influencers, a higher education external context specialization illustrates the reusability potentials of the proposed universal meta-concepts. Substituting higher-education-related meta-concepts and meta-models with arbitrary domain-dependent specializations further fosters the proposed universal meta-concepts’ reusability. Full article

The cosmetic industry is growing at an impressive rate worldwide. In the cosmetic field, natural-origin ingredients represent the new frontier in this industry. Among the main components of cosmetics, lipids, emulsifiers, rheological modifiers, preservatives, colorants, and antioxidants can be found. These compounds form emulsions, which are among the main cosmetic formulations. An important aspect in this regard is the evaluation of emulsions’ stability over time and emulsions’ production methodology. In this paper, a comparison is made between two emulsion production technologies, the Standard and the “One-Pot” methods, through the characterization of the raw material ABWAX^® Revomul, a multifunctional wax for cosmetic use which consists of a low-melting structuring wax of vegetal origin (Rhus wax) and a natural emulsifier (Polyglyceril-3 Stearate). First, we evaluated the affinity between the wax raw materials and emollients of different chemical nature; then, we analyzed the impact of the production method on the emulsions to identify similarities and differences. ABWAX^® Revomul demonstrated a high level of effectiveness in regard to stabilizing oil-in-water emulsions. This study suggests that from an industrial point of view, the application of the two procedures allows products with different characteristics to be obtained, consequently allowing a specific method to be chosen to obtain the desired product.
