Advances in recombinant protein bioprocessing: integrating technological innovation and environmental sustainability.

7 November 2026

A literature review assessed recombinant protein bioprocessing through technology and biomanufacturing readiness levels, alongside environmental measures such as life-cycle assessment and process mass intensity. It examined precision fermentation, AI-guided control and digital twins. Microbial production, including Escherichia coli, offered scalable, low-cost output, while reported emissions were about 20 kg CO2 equivalent per kg of product, against 351 kg for conventional pharmaceutical synthesis. Barriers to industrial scale-up remained, especially in emerging economies, supporting closer integration of technical planning and sustainability measures.

Valorizing watermelon rind waste into Plant-Based scaffolds for Proof-of-Concept cultivated meat production in a dynamic Fixed-Bed bioreactor.

7 November 2026

Researchers tested decellularised watermelon rind as a cultivated meat scaffold in a controlled fixed-bed bioreactor. They used 10% Tween-20 instead of Triton X-100, coated the material with Synthemax II and grew mouse C2C12 muscle cells for seven days. Residual DNA fell below 25 ng/mg, while porosity reached 85.6% and stiffness measured 36.8 ± 5.9 kPa. Dynamic culture produced greater metabolic activity and cell coverage than static culture. Cells differentiated and entered the scaffold. The constructs stayed intact after cooking.

Why cell agriculture struggles with meat and opportunities for non-food tissues.

7 November 2026

The authors argue that cultivated meat faces linked production and market constraints, making non-food products a distinct route rather than an easy escape. Their opinion article examines interactions among tissue depth, blood-vessel formation, stable cell behaviour, culture-medium cost, reactor size, food safety and public acceptance. It then applies this framework to simpler cell products and non-food tissues, where identity, function, lifespan, regulation and economics reshape the limits. Diversification therefore demands separate product strategies.

RNA thermometers as temperature-dependent tools for enhanced recombinant protein production in precision fermentation.

7 November 2026

An RNA thermometer raised temperature-controlled recombinant protein output in E. coli, which could help precision fermentation direct more carbon towards products without chemical inducers. Researchers placed fluorescent EmGFP under a fourU thermometer and tested cultures from 25°C to 40°C. Output peaked at 35°C, with specific productivity 2.6-fold above a derepressed control; the strongest regulatory effect occurred at 35.5°C. Product carbon allocation rose, while biomass and carbon dioxide allocation changed little. Product-per-acetate yield more than tripled at induction temperature. The system warrants further work on combined temperature and feeding control.

Sonication: A sensory engineering approach reshaping consumer acceptance for novel foods.

7 November 2026

A review assesses whether non-thermal ultrasound can improve acceptance of cultivated meat and other novel foods by changing sensory properties, a key barrier to repeat purchases. The authors combine research from sonochemistry, sensory science, economics, policy and marketing. They propose that ultrasound can alter flavour, texture, aroma and colour in plant, algae and insect proteins. Direct consumer evidence remains scarce, however. Better sensory quality may help, but price, labelling, food neophobia, cultural disgust and media influence still shape buying behaviour.

SCIENCE

Next-generation precision fermentation: integrating engineered cell factories, bioprocess intensification, and smart bioprocessing.

7 November 2026

Precision fermentation depends on combining engineered microbes with scalable processing, rather than improving strains alone, a distinction that shapes whether laboratory results can reach commercial production. The review examines microbial hosts, iterative strain design and multi-omics, intensified bioreactors, real-time monitoring and AI control, plus economic and environmental assessment. Case studies span artemisinin, insulin, organic acids, QS-21 and biopolymers. Feedstock variation, mass transfer, product recovery and costs remain barriers. Integrated design and early assessment offer the more credible route to scale.

β-lactoglobulin a new whey: Computational redesign improves stability and nutritional composition

7 November 2026

Researchers redesigned β-lactoglobulin to improve heat tolerance, production yield and branched-chain amino acid content, showing how computational methods may alter food protein performance and nutrition. ProteinMPNN changed up to 20% of the sequence, while PyRosetta identified sites for replacing as many as ten residues. Tests found variants retained similar secondary structures and oligomeric states. ProteinMPNN designs raised titres and thermal stability by up to 15°C. Enriched versions showed altered acid solubility. Surface hydrophobicity had some predictive value for yield. Broader predictive value remains unproven.

Induced Pluripotent Stem Cells in Non-Model Species: Applications and Challenges

7 November 2026

A review examines induced pluripotent stem cells in non-model species, where limited genomic data, reagents and culture methods constrain research relevant to conservation, medicine, agriculture and toxicology. It assesses reprogramming methods and applications including genetic rescue, laboratory-derived gametes, species-specific disease models, climate tolerance, disease resistance, cultivated meat and pollution testing. The authors find that vertebrates share the main biological machinery for pluripotency, while practical tools remain scarce. Progress depends less on biological feasibility than on building species-specific research infrastructure.

SCIENCE

An overview of the use of proteomics and peptidomics to characterize alternative protein foods.

7 November 2026

Proteomics and peptidomics are being applied to foods made from plants, insects, algae, fungi and cell agriculture, offering molecular checks beyond standard composition tests. This review examines mass spectrometry methods for identifying protein sources, spotting adulteration, assessing allergens, and measuring structure, digestion and peptide release. It also covers biomarkers drawn from conventional meat research and their use across newer protein matrices. Validated markers could support safety, nutrition, authenticity, formulation and regulation, though the abstract reports no new experiments.

Consumer Awareness, Perceptions and Acceptance of Mycoprotein Foods: An Exploratory Survey in China

7 November 2026

Chinese consumers showed broad interest in mycoprotein foods after receiving basic product information, but limited knowledge and cooking confidence may hinder purchases. An online survey of 1,197 adults measured awareness, perceptions and intentions, using paired comparisons and regression. Some 60.2% had heard of mycoprotein, while 11.6% claimed strong knowledge. After an explanation, 86.7% would try it and 76% would consider buying it. Taste expectations, curiosity, nutrition, confidence and worry shaped intentions, making practical guidance central to product testing and communication.

Potentially food-compatible cellulose acetate scaffolds functionalized with galactomannan and L-alanine: Effects on collagen production and early myogenic responses-A preliminary study.

7 November 2026

Researchers tested modified cellulose acetate fibres as candidate cultured-meat scaffolds, seeking a mix of muscle-like mechanics and useful cell responses. They added galactomannan, L-alanine or both, then measured material properties and responses in fibroblasts and myoblasts. The additions retained the fibre structure, increased fibre width, water affinity and stiffness, and produced elasticity similar to skeletal muscle. Initial cell attachment fell slightly. The combined formulation increased expression of Myf5, MyoD and COL1A1. These early results warrant further optimisation, not conclusions about tissue formation.

Food-Derived Umami Peptides: Linking Candidate Discovery, Experimental Validation, and Food Applications.

7 November 2026

Food-derived umami peptides are reviewed as tools for preserving savoury taste in alternative proteins and cultivated meat while reducing salt and standard seasonings. The authors compare protein sources and discovery methods, from sensory screening to virtual digestion, peptidomics and AI-led candidate selection. They assess chemical, sensory, instrumental and receptor evidence, alongside formulation, processing and production constraints. The review finds that structural modelling can explain mechanisms but cannot replace functional tests. Practical use now depends on open datasets, reproducible models and repeated food trials covering dose, off-flavours, yield and cost.

Evaluation of scaffold properties for cell-cultured food based on protein sources and their mixtures.

7 November 2026

Researchers compared edible scaffolds made from soy, pea and faba bean proteins, alone and in blends, to assess their suitability for cultivated meat. They measured physical, mechanical and cell-growth properties. All were pale yellow and porous. Soy absorbed the most water among single-protein samples, while adding soy improved uptake in pea or faba formulations. Blends degraded more after 48 hours and were harder and chewier. Single proteins supported better attachment and growth, led by faba bean. Protein choice presents a trade-off between texture and cell performance.

High-Level Mycoprotein Production through Metabolic Regulation of Concanavalin A-Like Lectin/Glucanase Domain-Containing Protein in Fusarium venenatum

7 November 2026

Deleting FvCLG in Fusarium venenatum raised protein content and curtailed ethanol formation, pointing to a genetic route for reducing carbon waste in fungal protein production. Researchers grew the FG31 deletion strain in a five-litre fermenter and compared it with the wild type. Protein reached 61.34%, up 22.41%, while glucose conversion into biomass and protein rose 44.02% and 76.41%, respectively. Transcriptomics found higher expression of nitrogen metabolism genes tied to amino acid synthesis and lower expression of glycolysis genes linked to ethanol. FvCLG warrants further testing as a production target.

A Reduced-Component Serum-Free Medium Supports Rapid Adipogenic Differentiation of Bovine Adipose-Derived Stem Cells under Serum-free Conditions

7 November 2026

Bovine adipose stem cells formed fat quickly in a five-component serum-free medium, potentially easing the timing mismatch between fat and muscle production in cultivated meat. Researchers tested AdB5 using lipid staining, transcriptomics, mixed-cell cultures and three-dimensional constructs. Lipid appeared on day two. By day 10, stained area was about 65 times larger than with standard serum-based culture. Gene activity showed early adipogenic changes, altered fatty acid metabolism and matrix remodelling. AdB5 also supported fat and muscle differentiation together. Evidence shows AdB5 can narrow the timing gap in these cultures.

Nutritional quality, sensory profile and textural improvement of mycoprotein nuggets derived from Rhizopus oligosporus with incorporation of various binding agents

7 November 2026

Rhizopus oligosporus mycoprotein nuggets offered nutritional gains over vegan and chicken products, but fell short of chicken on consumer preference, defining the main product challenge. Researchers compared nutrition and sensory ratings across the three nugget types, then used texture profile analysis to test three binders. The mycoprotein version had less fat, more fibre and essential amino acids, and a better fatty-acid profile. Modified tapioca starch at 10% increased hardness and chewiness most, though the mechanism behind the binders remains unclear.

Synthesis and Characterization of Naringin Phenolate Salts for Cultivated Meat.

7 November 2026

Researchers synthesised phenolate salts of naringin, a natural flavonoid, as possible cell-growth aids that could reduce cultivated meat’s reliance on costly growth factors. They prepared sodium, potassium, calcium and tetrabutylammonium forms, then verified their structures and tested solubility, reversibility and biological effects. Sodium and potassium salts dissolved readily in water, while calcium and tetrabutylammonium versions were less soluble. Acid treatment reversed salt formation. Early tests suggest selected salts may support cell proliferation, but evidence for use in cultivated meat remains preliminary.

SCIENCE

A data-driven evaluation of Optimization techniques in Cell Culture Media.

7 November 2026

Cell-culture media optimisation methods were compared on measured datasets, giving cultivated-food researchers evidence beyond simulations for reducing costly experiments. The authors tested optimisers on six published datasets with two benchmarks: one revealed hidden formulations sequentially, while the other set a fixed evaluation budget. Tests covered four surrogate models, two difficulty settings and batch sizes of one to 20. Gaussian-process Bayesian optimisation used the fewest evaluations, beating classical experimental designs and random search even when noise and multiple optima narrowed its lead. More complex models brought no gain.

Alterations of Fusarium venenatum mycelium upon sequential processing mediate the interfacial behavior and emulsion stability.

7 November 2026

Sequential nucleic acid removal and sterilisation weakened the emulsifying function of Fusarium venenatum mycelium, exposing a trade-off between food safety and product performance. Researchers measured composition, surface structure, mechanics, interfacial activity and emulsion stability after each processing step. Protein content fell from 50.96% to 43.47%, while atomic force microscopy showed rougher, flatter and less uniform surfaces. Untreated mycelium stabilised emulsions during storage, heating and salt exposure. Nucleic acid-removed material remained functional at higher concentrations, but sterilised material coalesced most readily. Processing conditions therefore need tighter control.

Microfluidic intestinal-chips as next-generation modeling strategies: Multifaceted emerging applications in food research, functional foods and personalized nutrition.

7 November 2026

A review assesses microfluidic intestinal chips as models for food research, finding they could improve tests of nutrition, safety and individualised diets while aiding cultivated meat and other new foods. It examines chip designs and applications, alongside links with biomaterials, stem cells, gene editing, 3D bioprinting and artificial intelligence. The authors say current systems still fail to reproduce key features, including nerves, blood flow and whole-body immune responses. These gaps make the platform useful, but not yet a full proxy for the human gut.

Impact of mycoprotein incorporation on the textural properties of hybrid yogurt gels

11 October 2026 · Proteins in Food Systems · Probiotics and Fermented Foods · Polysaccharides Composition and Applications

Fusarium venenatum and Nectria protein extracts had opposing effects in hybrid yoghurt, making source, dose and culture central to lower-dairy gel performance. Researchers replaced 0%, 20%, 60% or 100% of milk protein and used either L. helveticus or VIBE starter cultures. They tracked fermentation, rheology, viscosity and water loss during cold storage. Nectria raised elasticity and water retention, though high doses reduced viscosity. High Fusarium substitution weakened elasticity and increased water loss. VIBE improved viscosity and retention, but full replacement constrained L. helveticus acidification. Formulation choices therefore remain decisive.

Biotechnological Innovations in Food Technology: From Precision Fermentation to Sustainable Food Manufacturing

11 October 2026 · Microbial Metabolic Engineering and Bioproduction · Biochemical and biochemical processes · Advanced Scientific Research Methods

A review assesses how biotechnology moves into food production, because laboratory results alone do not ensure viable manufacturing. It synthesises research on precision fermentation, engineered microbes, enzymes, waste-stream use, scale-up, safety, regulation and public acceptance. Findings show that biological output must be considered alongside feedstocks, product recovery, food function, consistency and cost. Fermentation can make proteins, flavours, pigments, vitamins, enzymes and microbial biomass, while variable waste inputs hinder standardisation. The authors call for early life-cycle and economic analysis from organism design to market.

Transitioning from Lab to Industry in Cellular Agriculture: Pre- and Post-Cultivation Tissue Maturation Strategies

11 October 2026 · Tissue Engineering and Regenerative Medicine · 3D Printing in Biomedical Research · Meat and Animal Product Quality

A review of cultivated meat maturation methods examines how tissue structure and mechanics might move from laboratory work towards industrial production. It covers research published through 2026 on bioprinting, electrospinning, plant scaffolds, freeze-drying, ice templating, surface moulding, edible microcarriers and cell sheets. The reviewed literature finds that combining methods can improve fibre orientation, nutrient transport, extracellular matrix formation, metabolism and mechanical traits. Responsive scaffolds and adaptable culture systems may also enable tunable tissue behaviour, though industrial sustainability remains a prospect rather than an established result.

Cellular Agriculture Beyond Anthropocentrism: Speaking of Animals in an “Animal-Free” Future

11 October 2026

A critical animal-ethics analysis examines cultivated meat and fish, precision fermentation, and milk made from mammary epithelial cells, arguing that excluding animals from debate weakens ethical and policy scrutiny. The paper assesses how these methods alter reliance on animal bodies, the use of animals as means, and relations between humans and animals. It argues that discussion centred on sustainability, scale, regulation and consumer acceptance can invoke animals to justify innovation while omitting them from assessment. Credible deliberation must move beyond human interests.
