Protein Legume Supply-Chain Volatility Due to El Niño-Driven Yield Swings

Severe weather conditions have significantly impacted pulse crop production in Canada and Australia, causing substantial reductions in pea and fava bean availability for processing. These supply constraints have triggered widespread price increases throughout the contract manufacturing chain, particularly affecting the production costs of plant-protein isolates. In response, food manufacturers are implementing strategic measures, including geographical diversification of ingredient sourcing and increased investments in alternative protein production methods such as microbial fermentation and cellular agriculture, to minimize their exposure to climate-related supply disruptions.

Regulatory Restrictions Impact Insect Protein Adoption

Regulatory frameworks for insect proteins remain fragmented and restrictive, particularly in Western markets where consumer acceptance is already challenging. The UK's transition away from EU regulations resulted in stricter requirements, with only four insect species maintaining valid applications by 2024, while other edible insects must be removed from the market pending authorization ^{[3]Food Standards Agency, “Transitional Arrangements for Novel Foods,” food.gov.uk}. Allergenicity concerns, particularly cross-reactivity with crustaceans, impact regulatory assessments and labeling requirements. This creates additional compliance challenges for manufacturers, as they must implement strict protocols for allergen testing, documentation, and consumer safety warnings.^{[4]EFSA, “Safety Assessment of UV-Treated Mealworm Powder,” efsa.europa.eu}.
