Fungal Fermentation Replaces Part of Cocoa Powder in Extender Blends
Developers are using koji and mycelial fermentation to convert sunflower seeds, oats, and faba beans into roasted powders that mimic cocoa colour and bitterness, and chocolate makers blend them at 20% to 40% with cocoa to cut cost and volatility. Fermentation raises pyrazine and aldehyde levels that create roasted, nutty notes, and cuts bitterness in raw seeds. Pilot volumes of 100 to 1,000 tonnes a year have reached bakery, ice cream, and confectionery customers. Flavour parity is best in dark applications, since milk chocolate needs caramel notes, and buyers demand consistent batch quality before they commit to long contracts.
Market Impact: cocoa prices tripled since 2022
