Applied fungi · Helsinki

Applied mycology for functional ingredients.

Peter Petros, applied mycologist and engineer. I advise on all-things fungi specialising in functional-food ingredient industry, medicinal mushroom cultivation, processing, extraction, optimizations and even regulatory routes. I also take on fungal-bioeconomies, for future forestry and land restoration.

Typical questions

What I am asked (Medicinal Mushroom Industry)

Each maps to a work package, or to a single conversation. With a spec and claims in hand, start with the Spec & Claim Check (Medicinal Mushroom Industry): weekly queue at no charge, or a priority route credited against a pack.

β-glucan or triterpene contents are not competitive enough.Extraction Pack →
Can we utilise mycelium and save on fruiting - is this backed by science?Production Pack →
Bags, containers, lighting or bioreactor - what do I require for operations at scale, maintaining consistent yields.Production Pack →
Which markets are open to this new fungi-based ingredient: EU novel food, US GRAS, TGA...?Regulatory Pack →
Is there any in vitro, in vivo or clinical evidence for these compounds and what claims can we make?Commercialisation Pack →
The tincture formulation is unstable - how can it be improved? What QC specification can we construct?Commercialisation Pack →

Defined scope · agreed deliverables

Work packages

Medicinal mushrooms and functional ingredients. Each pack: consultations, a written briefing, agreed recommendations.

Production Pack

Species and strain, liquid culture and spawn, substrates, solid-state fermentation, grow-room and factory layout, growth parameters, pure mycelium, bioreactor design and scale-up.

Consultations · production briefing · recommendations for set-up and scale-up

Details →
Extraction Pack

Target compounds and fractions for a supplement, food ingredient or cosmetic: solvent-to-solid ratios, method selection and optimisation, technique evaluation, formulation direction.

Consultations · extraction briefing · recommendations on method, ratios and formulation

Details →
Commercialisation Pack

Compounds of interest; what the in vitro, in vivo and clinical evidence supports; formulation stability and quality control.

Consultations · evidence and quality briefing · recommendations for stability and QC

Details →
Regulatory Pack

Market analysis and regulatory sweep. Route to EFSA, US FDA, TGA or another authority; self-affirmed GRAS where the ingredient allows.

Consultations · regulatory briefing · agreed next steps

Details →

Also scoped per project: circular bioeconomy, Finnish forestry, nature-based solutions. Lectures and workshops on request.

Process

How an engagement runs

1
Intro call
45 minutes, no charge. Whether a pack fits, or a conversation is enough.
2
Scope
One page: goals, deliverables, timeline. Usually within a week.
3
Sessions
Scheduled video meetings with slides, followed by written summaries.
4
Deliverable
The briefing or plan, then a follow-up call.

Remote worldwide; on-site in Finland and the Nordics by arrangement. Larger projects and retainers are quoted separately.
