Bio-based Kojic Acid

How Bio-based Kojic Acid is Produced

Key Pathways:

1. Traditional Fungal Fermentation
• Kojic acid is naturally secreted by Aspergillus oryzae, Aspergillus flavus, and Aspergillus parasiticus when grown on carbohydrate-rich substrates like rice, corn, or molasses.
• The fermentation broth is filtered and kojic acid is recovered by crystallization.
2. Optimized Substrate Fermentation
• Agro-industrial wastes such as sugarcane bagasse, cassava peel, or molasses are used as carbon sources, reducing costs and improving sustainability.
3. Metabolic Engineering (Emerging)
• Engineered microbial strains (e.g., Yarrowia lipolytica, E. coli) are being explored to convert glucose directly into kojic acid, improving yields and process control.

Feedstocks: Glucose, starch hydrolysates, rice polish, molasses, agro-wastes.

Case Study: Glico (Japan) – Industrial Kojic Acid Production

Highlights:

• Glico has been producing cosmetic-grade kojic acid via Aspergillus fermentation since the 1980s.
• The product is widely used in dermatology and skincare, especially across Asia.
• Glico maintains strict quality and microbial strain controls to ensure purity and safety.

Timeline & Outcome:

• 1988: Kojic acid launched as a cosmetic whitening agent by Glico.
• 1990–2005: Became a staple ingredient in Japanese and Korean beauty products.
• 2018–2023: Glico expands kojic acid into Europe and North America through export partnerships.

Global Startups Working on Bio-based Kojic Acid

• Glico (Japan) – Global pioneer and main supplier of cosmetic-grade kojic acid.
• Symbiobeauty (Malaysia) – Uses local agro-waste for fungal fermentation of kojic acid.
• MycoTechnology (USA) – Investigating fungal metabolites for cosmetic and nutraceutical use.
• Evolva (Switzerland) – Exploring synthetic biology-based production of rare fungal metabolites, including kojic acid derivatives

India’s Position

• India has no commercial kojic acid manufacturing facility as of now.
• Domestic demand is rising in cosmetics, skin care, and food preservatives, especially with increasing awareness of natural whitening agents.
• India’s abundant sugar and starch waste streams offer low-cost feedstock potential.

Commercialization Outlook

Market & Demand

• Global kojic acid market: ~$80–100 million (2024), CAGR ~7.2%.
• Applications:
• Skincare and dermatological creams
• Food preservation (anti-browning agent)
• Antioxidant additives in pharma and supplements
• Biopigment and resin intermediates

Key Drivers

• Rising consumer preference for plant-based, non-toxic skin lightening agents.
• Clean-label trends in cosmetics and food industries.
• Emerging use in cosmeceuticals, anti-aging creams, and bio-preservatives.
• Growing exploration of mycofermentation as a platform for high-value chemicals.

Challenges to Address

• Low yield and product inhibition during fungal fermentation.
• Need for high-purity and stable forms for skincare formulations.
• Difficulty in scaling up solid-state fermentation systems.
• Regulatory clarity required for new biotech-produced cosmetic ingredients in India.

Progress Indicators

• 1988–1990: Kojic acid enters Japanese cosmeceutical markets (Glico).
• 2000–2015: Expanded to ASEAN and Korean markets.
• 2018–2023: Cosmetic-grade kojic acid accepted in EU and US markets.
• India: CSIR and academic research on molasses and starch-based fungal fermentation; no industrial-scale production yet.

Kojic acid production via traditional fungal fermentation is at TRL 9 globally (fully commercial), while synthetic biology or engineered strain-based production is at TRL 5–7. In India, kojic acid remains at TRL 3–4, with R&D focused on substrate optimization and fungal isolation.

Conclusion

Bio-based kojic acid is a proven, high-value cosmetic and food ingredient that exemplifies the power of fungal fermentation. Its commercial success in Japan and Korea — particularly through Glico’s long-standing production — has paved the way for clean-label, allergen-free skincare formulations. As global demand for natural cosmeceuticals rises, kojic acid’s sustainability and biological origin give it a clear market edge. India, with its rich microbial biodiversity and agro-waste streams, has both the technical foundation and feedstock base to participate in this niche, provided scale-up infrastructure and regulatory clarity are strengthened.
