In early January 2026, The Washington Post published an in-depth analysis by Andrew Van Dam titled “Why are malnutrition deaths soaring in America?” that examined a sharp rise in US deaths attributed to malnutrition, particularly among older adults. Using Centers for Disease Control and Prevention (CDC) mortality data, the report indicates that deaths listing malnutrition as the underlying cause have increased roughly sixfold over the past decade, with adults aged 85 and older experiencing the fastest increase. Van Dam explains that this increase reflects both nutritional vulnerability among older Americans and improved clinical recognition and reporting of malnutrition as a diagnosable condition rather than merely a symptom of other diseases (Van Dam, Washington Post, January 5, 2026). Malnutrition among older adults is not a fringe issue—it has real health consequences. Independent health research shows that malnutrition in people over 65 often leads to longer hospital stays, higher risk of complications and falls, and worse recovery outcomes. Even among older adults living at a normal weight, inadequate intake of protein and micronutrients increases morbidity and mortality. (Edmisten, A. 2003. “Malnutrition and Food Insecurity in Older Adults.” North Carolina Medical Journal 84, no. 2: 106–109. https://doi.org/10.18043/001c.73010) These data highlight a gap between what older adults physiologically need and what the current food system provides. Aging bodies require higher protein density, better micronutrient bioavailability, easier-to-chew textures, and highly palatable foods that stimulate appetite, yet the lowest-cost foods available to many seniors are often energy dense but nutrient poor. When food prices rise faster than Social Security and fixed incomes, people shift toward cheaper, shelf-stable products that are low in protein, fiber, and micronutrients, accelerating muscle loss, frailty, and immune decline. Food insecurity among older Americans has reached historically high levels in recent years. The USDA's Economic Research Service reports that in 2023, 9.3% of households with an adult aged 65 or older experienced food insecurity at some point during the year, with even higher rates among seniors living alone. Rising food prices and the erosion of fixed incomes have made it increasingly difficult for older adults to reliably access nutritious food (US Department of Agriculture, Economic Research Service. 2024. “Food Insecurity in Households With Older Adults.” Charts of Note. https://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=111151). Formulation choices determine whether affordable foods deliver 25 g of high-quality protein per meal; meaningful vitamins D and B12, iron, zinc, and omega-3s; and textures suitable for dysphagia and dentition loss. Processing methods shape whether nutrients remain bioavailable, whether flavor and aroma stimulate appetite, and whether foods are culturally familiar and emotionally comforting to older consumers. In a stagflationary environment where food affordability is under pressure, the food sector cannot rely on premium nutrition products alone; it should look to provide low-cost, high-nutrition foods that work within SNAP, Meals on Wheels, and long-term care budgets. Formulation decisions that improve protein density, micronutrient delivery, texture, and affordability can help older adults remain healthy and independent. The following are highlights of studies published in the Journal of Food Science during the past month and address many areas such as consumer acceptance, food security, food nutrition, food production sustainability, and food safety: This research demonstrates that extruded rice desserts fortified with micronized dispersible ferric pyrophosphate (MDFP) can significantly improve iron bioavailability while maintaining strong sensory acceptance among children—an important advance for food-based strategies to combat iron deficiency anemia. Iron deficiency remains one of the most widespread micronutrient challenges globally, particularly among school-aged children. While ferric pyrophosphate is widely used in fortification due to its sensory stability, its low solubility has historically limited absorption. This research shows that embedding MDFP into an extruded rice matrix overcomes that limitation, effectively transforming a traditional rice dessert into a high-performance iron delivery system. In a controlled feeding study using Wistar rats, iron-fortified rice desserts prepared with either cow's milk or soy soluble protein extract significantly improved iron nutritional status compared with standard control diets. Importantly, the choice of liquid ingredient did not compromise iron absorption. The findings suggest that extrusion reduces mineral aggregation and promotes more direct interaction with intestinal absorption sites. The study also addressed a critical hurdle in child nutrition programs: acceptance. Sensory testing with school-aged children showed that the fortified rice desserts were well received, indicating that nutritional gains did not come at the expense of taste or texture. The researchers state that incorporating MDFP into extruded rice products offers a low-cost, scalable, and culturally familiar approach to iron fortification. And, it is particularly suited to regions where rice-based foods are dietary staples. https://doi.org/10.1111/1750-3841.70805 This study demonstrates that sumac sorghum bran can be successfully incorporated into expanded, corn-based extruded snacks to significantly boost antioxidant content while maintaining acceptable physical and sensory qualities. The research evaluated how bran inclusion levels and extrusion processing conditions influence product performance. Using a three-factor response surface methodology, the authors tested sorghum bran inclusion rates from 0% to 30%, screw speeds from 150 to 300 rpm, and feed rates from 9 to 25 kg/h. As expected, higher bran levels reduced expansion ratio and increased product density, reflecting the fiber-rich nature of sorghum bran. However, these changes were accompanied by substantial gains in nutritional functionality, including marked increases in total phenolic content and oxygen radical absorbance capacity (ORAC). Optimization modeling identified 20% sorghum bran, a screw speed of 184 rpm, and a feed rate of 21.76 kg/h as the best overall conditions. This formulation achieved a strong balance of expansion (ER 3.25), high antioxidant potential (4832 µg GAE/g total phenolics; 165 µmol TE/g ORAC), and moderate tannin levels. The researchers concluded that the use of tannin-rich sorghum bran as a functional ingredient for developing antioxidant-enhanced extruded snacks can upcycle grain byproducts into value-added, healthful foods. https://doi.org/10.1111/1750-3841.70840 Researchers from China have identified the root cause of package swelling in Hubei broad bean paste, a traditional fermented food, and demonstrated an effective strategy to prevent this spoilage defect. The research addresses a persistent quality issue that leads to product rejection, economic losses, and reduced consumer confidence in fermented paste products. The research team isolated a dominant gas-producing bacterium from swollen cans and identified it as Clostridium tyrobutyricum strain LG12 using 16S rDNA sequencing. Physiological characterization showed that the organism thrives under conditions typical of fermented paste production, growing optimally at pH 5–7, tolerating salt concentrations up to 10%, and surviving intense heat treatment, including 20 min at 100°C. These traits help explain why the bacterium can persist through conventional processing steps. Traceability analysis revealed that the contamination originated from fermented chili, a key raw material used in Hubei broad bean paste formulations. This finding highlights the importance of ingredient-level microbial control in traditional fermentation systems. To address the problem, the researchers evaluated several food-grade antimicrobials for their ability to suppress bacterial growth. An optimized combination of nisin, ε-polylysine hydrochloride, and sodium diacetate achieved more than 99% inhibition in laboratory tests. When applied directly to the broad bean paste system, this formulation successfully prevented gas formation and package swelling under processing conditions. https://doi.org/10.1111/1750-3841.70849 Researchers based primarily in India, with collaboration from South Korea, have developed a biodegradable, pH-responsive intelligent packaging film that visually indicates chicken freshness in real time. The study reports the fabrication of a composite film made from dual-modified elephant foot yam (Amorphophallus paeoniifolius) starch, blended with polyvinyl alcohol (PVA) and enriched with an anthocyanin-rich butterfly pea flower (Clitoria ternatea) extract. The approach targets growing industry demand for sustainable packaging materials that can both reduce plastic use and actively communicate product quality. The butterfly pea extract provides the film's sensing function. Rich in anthocyanins and flavonoids such as rutin, delphinidin, and quercetin, the extract undergoes distinct, reversible color changes as pH increases during meat spoilage. Structural and spectroscopic analyses confirmed that the extract was well dispersed within a semicrystalline starch–PVA matrix, allowing the film to retain mechanical integrity while remaining highly responsive to pH variation. Incorporation of the extract increased film thickness modestly while improving moisture barrier performance and dramatically enhancing color sensitivity across a broad pH range. Film performance was optimized at moderate extract levels. At 3% butterfly pea extract, the films showed the best balance of tensile strength and flexibility, along with strong antioxidant and antimicrobial activity against common foodborne bacteria. When applied to chicken packaging, the films exhibited clear, progressive color shifts that closely tracked established freshness indicators, including microbial growth, rising pH, lipid oxidation, and total volatile basic nitrogen. Overall, the work demonstrates that elephant foot yam starch, an underutilized tropical crop, can be successfully transformed into a smart, biodegradable packaging material capable of real-time freshness monitoring. The findings point to a scalable strategy for integrating natural colorimetric sensors into sustainable food packaging, with potential benefits for shelf-life management, food safety, and waste reduction across poultry and other perishable protein categories. https://doi.org/10.1111/1750-3841.70758 This study by researchers from Italy provides a detailed sensory and chemical description of rosemary essential oil, revealing how genotype and geographic origin shape its characteristic aroma. The group analyzed essential oils from six rosemary genotypes using descriptive sensory analysis alongside gas chromatography–olfactometry and GC–MS to identify the compounds most responsible for rosemary's distinctive odor profile. Sensory evaluation showed clear differences among the oils, particularly in rosemary-like, eucalyptus/balsamic, and fruity notes. These perceptual differences were supported by analytical data: a total of 32 odor-active compounds were detected, with seven compounds emerging as dominant contributors to overall aroma intensity. These included well-known rosemary markers such as 1,8-cineole and α-pinene, alongside linalool and fenchol, as well as highly potent compounds present at extremely low concentrations. The study indicates that 1-hexen-3-one and β-damascenone are impactful odorants in rosemary essential oil, with 1-octen-3-one and fenchol also shown to play a large sensory role. Despite their trace-level concentrations, these compounds exhibited high odor activity values. https://doi.org/10.1111/1750-3841.70786 Guarana-based beverages—consumed in Brazil for their energizing and functional properties—appear far more microbiologically robust than previously assumed. While earlier studies have identified potentially harmful bacteria in guarana powders, sticks, and soda fountain systems, this work provides the most comprehensive assessment to date of whether those microorganisms can actually survive and grow in finished guarana beverages. Researchers evaluated the stress tolerance, enzymatic activity, and antimicrobial resistance of 17 bacterial isolates recovered from the guarana production chain, including Bacillus cereus, Klebsiella, Cronobacter, Pseudomonas, and Salmonella. Most isolates grew well only under moderate conditions—neutral pH and temperatures between 25°C and 42°C—and were strongly inhibited by acidic environments (pH ≤3.5), extreme temperatures, and reduced water activity. Several isolates, particularly B. cereus, showed lipolytic and proteolytic activity associated with spoilage potential, and some displayed resistance or intermediate resistance to multiple antibiotics, underscoring upstream food safety concerns tied to raw ingredients. Crucially for beverage manufacturers, none of the tested bacteria were able to grow in commercial guarana beverages. When eight representative isolates were inoculated into six different products—three reconstituted guarana-flavored powdered drinks and three ready-to-drink refreshments—all formulations produced rapid population declines, with reductions of up to 6 log units. The strongest inhibitory effects were observed in reconstituted powdered drinks with pH values near 3.0, while ready-to-drink beverages also consistently suppressed microbial survival over time, even at temperatures favorable for bacterial growth. This research indicates that although contamination risks exist earlier in the guarana supply chain, the intrinsic acidity of finished guarana beverages provides a substantial safety barrier. The study demonstrates the importance of controlling postprocess contamination while also confirming that current guarana beverage formulations—both powdered and ready to drink—are inherently antagonistic to bacterial growth, supporting their microbiological stability and shelf life. https://doi.org/10.1111/1750-3841.70848 Nonthermal preservation technologies are gaining momentum as the seafood industry seeks to extend shelf life without compromising sensory quality. This cross-cultural study examines whether mild osmotic dehydration can meet consumer expectations in different European markets, using gilthead seabream fillets as a model product. The research compared consumer responses in Greece and Denmark, two countries with distinct fish cultures and consumption habits. A total of 158 consumers evaluated treated and untreated fillets over 9 days of chilled storage, rating liking and sensory characteristics using hedonic scales and check-all-that-apply (CATA) descriptors. Results showed clear cultural differences in how freshness, treatment, and specific sensory cues influenced acceptance. Greek consumers were strongly driven by perceptions of freshness, with marine notes supporting liking and fishy off-flavors acting as major deterrents, regardless of treatment. In contrast, Danish consumers responded more positively to the osmotically treated fillets, with umami and juiciness emerging as key drivers of liking and lactic sour notes limiting acceptance. Treatment effects mattered more in Denmark than in Greece. While Greek consumers tended to prioritize traditional freshness cues linked to daily exposure to fresh fish, Danish consumers—who generally have less routine access to very fresh seafood—were more receptive to the mild preservation approach. Across storage time, osmotically treated fillets maintained sensory appeal better, particularly for Danish participants, indicating a stronger market fit in Northern European contexts. Mild osmotic dehydration shows clear potential to extend the market reach of chilled fish products, but success depends on aligning sensory profiles and communication strategies with local food culture. Understanding how different consumer groups define freshness, off-flavors, and desirable texture will be critical for translating promising preservation technologies into commercially successful products across borders. https://doi.org/10.1111/1750-3841.70854 These researchers from the Armand-Frappier Santé Biotechnologie Research Centre have developed a biobased active packaging film that blends gelatin with ethyl cellulose to overcome gelatin's usual weaknesses in water resistance and barrier performance. In the optimized base film (gelatin:ethyl cellulose at 1:2), the ethyl cellulose network sharply reduced water solubility compared with gelatin alone, creating a more stable, packaging-ready matrix. The team then used trans-cinnamaldehyde (a GRAS flavor compound) as both a bioactive ingredient and a chemical crosslinker and incorporated silver nanoparticles as an additional antimicrobial agent, aiming to produce a stronger, less permeable, and microbiologically protective film suitable for direct contact with sliced meat. The resulting crosslinked nanocomposite delivered major functional gains. Crosslinking reached about 57%, and film performance improved on multiple fronts—water solubility dropped to ∼0.33%, water vapor permeability decreased to ∼2.39 g·mm·m−2·day−1·kPa−1, and tensile strength increased to ∼9.6 MPa. Thermal stability also increased substantially, with maximum decomposition temperatures reported in the ∼370°C–380°C range and a glass transition temperature around 29.5°C. FTIR data supported the proposed chemistry—covalent amide/imine formation between cinnamaldehyde and gelatin (consistent with Schiff-base-type reactions) and hydrogen-bond-driven stabilization between gelatin and ethyl cellulose—helping explain the denser, more water-resistant polymer network. The films showed broad antibacterial activity against both pathogens and spoilage organisms, with in vitro inhibition reported across roughly a 27%–54% range. In a practical in situ trial on chilled sliced meat, packaging with the cinnamaldehyde–silver nanoparticle nanocomposite significantly slowed microbial growth and extended usable shelf life by up to 9 days. For meat processors and packaging developers, the study indicates that gelatin–ethyl cellulose films loaded with trans-cinnamaldehyde and AgNPs can be a promising technique to achieve more sustainable, high-performance active packaging. https://doi.org/10.1111/1750-3841.70851 As food manufacturers look for that deliver nutrition and functionality, can be a practical ingredient In this researchers evaluated made with conventional using the model to and antioxidant alongside nutritional and key quality with the control delivered a different nutrition higher protein dietary and and in vitro the showed significantly total and higher also min in the intestinal while conventional showed a more potential for improved in a processing the ingredient did not compromise water absorption and were not significantly different from the The major was was a by consumers.
