The defatted sesame kernel is a high-quality source of polysaccharides. However, there is a lack of research on the extraction, purification, structural characterization, and application of polysaccharides from defatted sesame kernel. This study primarily aimed to characterized the structural features of polysaccharides from sesame kernel and investigated their potential applications. Polysaccharides were extracted from defatted sesame kernel using ultrasound-assisted alkali extraction with 5 % (w/w) KOH at 50 °C for 30 min. Following decolorization, deproteinization, and column chromatography with NaCl elution (0, 0.1, 0.3, 0.5, and 0.7 mol/L), five purified polysaccharide fractions (SMP-1, SMP-2, SMP-3, SMP-4, SMP-5) were obtained. The composition and antioxidant activity of polysaccharides were analyzed. SMP-2 was the dominant fraction (36.5 %) and composed of arabinose (42.9 %), galactose (33.3 %), rhamnose (10.2 %), glucuronic acid (6.8 %), and others. The linkage types of SMP-2 are mainly characterized by a linear backbone of (1→5)-linked α-l-arabinofuranosyl units. Additionally, the study found that SMP-1, SMP-2, and SMP-3 remained stable below 250 °C, suggesting their potential use in thermally processed foods requiring heat-resistant polysaccharides. SMP-4 and SMP-5 exhibited pronounced free radical scavenging activities. These findings provide valuable insights for the in-depth research and industrial application of sesame polysaccharides.

Thermal properties of mustard protein isolate (MPI) were evaluated by differential scanning calorimetry. MPI is mainly composed of albumins 2S and globulins 12S fractions as the major protein fractions. Also, different conditions affected thermal stability of the used MPI such as the protein concentration, the heating rate, pH of the dispersing medium, addition of different amount of sugar and salts (NaCl or CaCl2). Results revealed that all these conditions must be considered when MPI is used as ingredient in different food matrices, particularly in those subjected to heat treatment such as cooking. Feasibility of beef patty making by using MPI as ingredient was also studied at 1, 2 and 3 % level on meat basis. This study showed that all fresh patties looked similar as the control; indicating that the visual acceptability of the MPI-added beef patty is good. TBARS values were evaluated for fresh samples stored at 4 °C for 24 h and -20 °C after 6 months. Results showed that MPI-added patties have the lowest TBARS values. Also, MPI-added beef patty cooking yield was higher than control (78.27 ± 1.03 %) when MPI was added at 3 % level. This study demonstrated the potential of using MPI in beef patty because of its antioxidant protective effect and good technological impact on product quality.

This study systematically evaluated the mechanistic effects of four stabilization technologies—infrared (IR), vacuum-assisted infrared (IR-VC), hot air-assisted IR (IR-HA), and radio-frequency (RF)—on rice bran oil yield, lipid stability, and bioactive compound retention. All treatments were designed to deliver comparable thermal energy inputs, enabling quantitative comparisons. Among the methods, IR-VC achieved the highest extraction yield (8.87 g/100 g dry basis), while RF treatment provided the strongest suppression of hydrolytic and oxidative deterioration, resulting in the lowest acid value (14.86 mg KOH/g) and peroxide value (6.16 meq O2/kg) after 8 weeks of storage. Shelf-life projections based on free fatty acid accumulation at 30 °C indicated substantial extensions: RF (39.2 days), IR-VC (27.4 days), IR (16.8 days), and IR-HA (13.4 days), compared with only 1.7 days in non-stabilized controls. IR-VC preserved the highest levels of bioactive compounds during 8-week storage, including γ-tocotrienol (1033 mg/kg), α-tocopherol (360 mg/kg), and γ-oryzanol (6920 mg/kg). These results demonstrate that IR-VC offers a balanced strategy for maximizing oil recovery and bioactive retention, while RF is most effective for extending storage stability. The mechanistic insights provided here can guide engineering design and optimization of rice bran stabilization processes for commercial RBO production.

Agrifood side streams from pumpkin processing—seed press-cake and seed hulls—provide underexploited sources of proteins, fibers, lipophiles, and phenolics. This review links green-extraction chemistry to structure–function behavior of pumpkin seed proteins. We evaluate extraction and modification routes by how well they serve food end-uses, grading evidence across yield, purity, digestibility, and interfacial/gel performance. We show that aligning process sequence with function—oil polishing and phenolic tuning before protein isolation, then moderate structure modification—outperforms one-step approaches for neutral-pH beverages, while alkali ± intensification suffices for savory bakery/meat systems. We map molecular determinants to solubility, interfacial activity—emulsifying activity index (EAI) and emulsion stability (ES)—foaming, and gelation, and how phenolics and antinutrients modulate functionality, digestibility, and bioaccessibility. A matrix benchmarks supercritical carbon dioxide (SC-CO₂), deep eutectic solvents (DES), subcritical ethanol–water, pH-shift/isoelectric precipitation, enzyme-assisted routes, and physical intensification for selectivity, scalability, and eco-metrics. Moderate ultrasound or heat-assisted pH-shifting increases solubility and emulsification; mild thermal/alkaline regimes reduce phytic acid and trypsin inhibitors and raise in-vitro protein digestibility (≈86→96%); protein–polysaccharide hybrids enhance oxidative stability. We outline a zero-waste biorefinery sequencing SC-CO₂ for oil; DES or subcritical ethanol–water for phenolics; and aqueous/enzymatic steps for proteins/peptides with solvent recycling. We conclude with priorities for standardization, bioavailability, scale-up, and clean-label formulation.

This review examines the effectiveness of green techniques, including Ultrasound-Assisted Extraction (UAE) and Deep Eutectic Solvents (DES), for extracting polyphenols from fruit waste. DES significantly extracts bioactive compounds and ensures high selectivity, sustainability, and enhanced solubility. The combined effect of UAE-DES enhances extraction yield, reduces processing time, and decreases solvent use, making it a greener alternative to conventional extraction methods. UAE-DES synergy maximizes yield with reduced energy consumption, while also serving as a substitute for toxic organic solvents in environmentally friendly extraction processes. The UAE technique utilizes high-frequency sound waves to disrupt cell walls, whereas DES employs environmentally friendly solvents for the selective extraction of phytocompounds. The review examines the effect of process parameters, including those of UAE and DES, on extraction efficiency, such as solvent type, temperature, and time. The extracted polyphenols were further evaluated for their antioxidant activity, bioavailability, and potential health benefits. In addition, the review examines the potential applications of the extracted polyphenols in the food, pharmaceutical, and cosmetic industries, leveraging their natural preservative, flavor-enhancing, and therapeutic properties. This study aims to provide methods for converting fruit waste into useful, health-benefiting compounds, thereby promoting sustainability by reducing waste and valorizing natural resources.

Brown seaweed, a type of marine macroalgae, is a sustainable resource for human consumption that plays an important role in several cultures, including Aotearoa New Zealand. Brown seaweeds have a relatively high content of phenolic compounds and, exclusively, phlorotannins, which have garnered increasing attention due to their bioactive properties. Applications of these phenolic compounds have been developed for therapy, food additives, material manufacturing, and fertilisers. Among these, their antioxidant property is especially important for the food industry, but limited research has been conducted. This review investigated the nutrition profile of New Zealand brown seaweed species, which are rich in macronutrients, and addressed safety concerns regarding heavy metals and iodine. Phlorotannin content, extraction methods, and their promising antioxidant activities were then compared between New Zealand and global brown seaweeds. According to the current research, they have comparable phlorotannin content and antioxidant activities. More importantly, the potential of applying brown seaweed species as an antioxidant in food matrices was explored. Although successful trials have utilised (New Zealand) brown seaweed extracts as antioxidants for various foods, their widespread commercial use remains rare. The seaweed industry in New Zealand has not been established, and the seaweed is heavily reliant on wild harvest and imports. In conclusion, more effort is needed to develop a comprehensive, evidence-based understanding of New Zealand's brown seaweeds, ultimately enabling the commercialization of this promising resource as antioxidants in food products.

Value added food bars rich in bioactive and antioxidant content developed by diverse amalgamations of agro-industrial products offer numerous health benefits that extend beyond basic nutritional value. The objective of this research was to develop and evaluate flaxseed food bars with 70 % (T1), 60 % (T2) and 50 % almond butter (T3). The study also aimed to explore their physicochemical, microbial, sensory as well as antioxidant attributes throughout a 60-day storage. Results revealed a notable improvement in the total phenolic (TP) content and antioxidant activity of the food bar (T1). TP content reached a peak value of 38.69 ± 0.72 mg GAE/100 g (T1) while the lowest value (36.29 ± 0.68 mgGAE/100 g) was recorded in T3. Similarly, DPPH radical scavenging activity peaked at 79.37 ± 0.72 molAAE/100 g in T1, and was lowest (76.97 ± 0.75 molAAE/100 g) in T3. T1 also showed significantly high (p≤0.05) fiber content (6.56 ± 0.06 %). Yeast and mold count varied from a minimum of 1.43 ± 0.09 CFU/g (T1) to a peak of 1.99 ± 0.12 CFU/g (T3) and similarly, total plate count ranged from 2.28 ± 0.12 CFU/g (T1) to 2.92 ± 0.09 CFU/g (T3). Oat-flaxseed bars with 70 % almond butter (T1) emerged as a preferred option for the consumers based on the significantly high (p≤0.05) color, texture, mouthfeel, and overall acceptability results.

In this study, Abelmoschus esculentus (L.) Moench polysaccharides (APs) were prepared by mild acid extraction and ethanol precipitation, followed by purification with ion-exchange chromatography on a DEAE Sepharose Fast Flow column. The crude polysaccharides (AP-Crude) were purified to obtain AP2. The backbone of AP2 mainly consists of (1→4)-linked galactose, (1→4)-linked glucose, (1→2,4)-linked rhamnose, and (1→2)-linked rhamnose residues, with terminal glucose and galactose units. AP2, with an average molecular weight of 182.5 × 10³ g/mol, was further modified by hydrolysis (HS), producing the derivatives AP2-HS1, AP2-HS2, and AP2-HS3, with average molecular weights of 107.2 × 103, 52.6 × 103, and 19.8 × 103 g/mol, respectively. The immune-enhancing effects of AP2 and its derivatives were evaluated, showing significant increases in NO and PGE2 production. Interestingly, AP2-HS1 exhibited greater immune-enhancing potential than the other fractions. AP2-HS1 also upregulated the expression of COX-2, iNOS, TNF-α, IL-1β, and IL-6 by promoting phosphorylation of ERK, JNK, p38, and p65. Additionally, AP2 and its derivatives enhanced radical scavenging activity against DPPH, ABTS⁺, and •OH. These results demonstrate that all polysaccharides possess antioxidant activity and activate macrophages through the MAPK and NF-κB pathways. Overall, partial hydrolysis effectively enhanced the antioxidant and immunomodulatory functions of AP2, with AP2-HS1 showing the strongest potential as a macrophage-activating immunomodulator. The work delivers a functional, food-grade immunomodulator that supports food and nutrition security, sustainable use of agricultural resources, and functional-ingredient development for industrial adoption.

AP2, with an average molecular weight of 182.5 × 10³ g/mol, was further modified by hydrolysis (HS), producing the derivatives AP2-HS1, AP2-HS2, and AP2-HS3, with average molecular weights of 107.2 × 10<sup>3</sup>, 52.6 × 10<sup>3</sup>, and 19.8 × 10<sup>3</sup> g/mol, respectively. The immune-enhancing effects of AP2 and its derivatives were evaluated, showing significant increases in NO and PGE<sub>2</sub> production. Interestingly, AP2-HS1 exhibited greater immune-enhancing potential than the other fractions. AP2-HS1 also upregulated the expression of <em>COX-2, iNOS, TNF-α, IL-1β</em>, and <em>IL-6</em> by promoting phosphorylation of ERK, JNK, p38, and p65. Additionally, AP2 and its derivatives enhanced radical scavenging activity against DPPH, ABTS⁺, and •OH. These results demonstrate that all polysaccharides possess antioxidant activity and activate macrophages through the MAPK and NF-κB pathways. Overall, partial hydrolysis effectively enhanced the antioxidant and immunomodulatory functions of AP2, with AP2-HS1 showing the strongest potential as a macrophage-activating immunomodulator. The work delivers a functional, food-grade immunomodulator that supports food and nutrition security, sustainable use of agricultural resources, and functional-ingredient development for industrial adoption.</div></div>","PeriodicalId":73040,"journal":{"name":"Food chemistry advances","volume":"9 ","pages":"Article 101142"},"PeriodicalIF":0.0,"publicationDate":"2025-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foodomics is an emerging multidisciplinary field that applies omics technologies such as genomics, proteomics, metabolomics, transcriptomics, and nutrigenomics to improve the understanding of food composition, quality, safety, and traceability. This review highlights recent advances in analytical methods for assessing nutrient profiles, identifying contaminants, and verifying food authenticity. Case studies demonstrate the practical impact of Foodomics, including metabolomics for authenticating horse milk adulteration, proteomic profiling for tracing seafood species and dairy product origins, and transcriptomic approaches for monitoring flavonoid biosynthesis in seeds and nitrogen stress responses in apple plants. In cereal and fruit-based products, Foodomics has also been employed to assess processing impacts through volatile fingerprinting and enzyme activity profiling. Despite these successes, widespread adoption is limited by high costs, data complexity, and the need for advanced bioinformatics and technical expertise. The variability of food matrices and dynamic processing environments presents further analytical challenges. A more balanced view of the field is necessary, including critical evaluation of methodological limitations and reproducibility concerns. Future directions involve integrating omics data with technologies such as machine learning and blockchain to enhance predictive modeling and supply chain transparency. Advancements in portable and affordable platforms along with standardization of protocols will be essential for broader implementation, particularly in developing countries. Collaboration among researchers, industry, and regulators will be vital to establish clear regulatory frameworks and realize the full potential of Foodomics in improving food safety and public health outcomes.

This study aimed to combine headspace gas chromatography ion mobility spectrometry (HS-GC-IMS) with chemometric analysis to investigate the differences in physicochemical characteristics and volatile organic compounds (VOCs) among walnut oils obtained through three different processing methods: hydraulic cold pressing of walnut kernels with the seed coat (DPM), hydraulic cold pressing of walnut kernels without the seed coat (QPM), and supercritical CO2 extraction of walnut meal left after hydraulic pressing of walnut kernels without seed coat (QPC). A comprehensive analysis of the physicochemical characteristics, VOCs, and fatty acid composition of the walnut oils was conducted, accompanied by correlation analysis. The results indicate that QPC exhibited the highest peroxide value (POV) at 0.16 g/100 g. Concurrently, QPC acid value (AV) was significantly higher than that of DPM and QPM by 0.24 mg/g and 0.26 mg/g, respectively (p < 0.05). The ratio of polyunsaturated fatty acid (PUFA) to monounsaturated fatty acid (MUFA) was 7.75, which is consistent with the characteristic high-PUFA profile of walnut oil. A total of 50 volatile organic compounds (VOCs), including aldehydes, alcohols, ketones, esters, acids, and terpenes, were identified using HS-GC-IMS technology. Partial Least Squares Discriminant Analysis (PLS-DA) identified 20 characteristic VOCs (VIP>1). The study further revealed significant correlations among the physicochemical quality of walnut oil, its fatty acid composition, and these key VOCs. This research provides essential theoretical insights for assessing how different processing conditions influence nutrient retention and VOCs profiles in walnut oil.
