Microbial Metabolic Engineering and Bioproduction
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.

Proteins in Food Systems
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.

Proteins in Food Systems
A review assesses plant proteins from major crops as edible scaffolds for cultivated meat, a route that could reduce dependence on animal materials and lower environmental effects. It compares extraction methods and newer processing technologies, then examines extrusion, freeze-drying, electrospinning, hydrogels and polymer blends. The authors find that purity and processing shape scaffold strength, pore structure and cell compatibility. However, better support for muscle-cell attachment, growth and maturation, along with repeatable scale-up, remains necessary before these materials can fulfil that role.
