We supply high-quality and fresh Thaumatococcus daniellii arils — the natural source of the sweet protein Thaumatin, used by flavor and ingredient companies worldwide.

B.To (Build Together) operates in Cameroon, working directly with local farmers and artisans to ensure ethical sourcing and sustainable production.

Our ~250 artisans perform manual extraction with special knives to preserve the natural purity and sweetness of the arils. This handcrafted process ensures exceptional quality and consistency.

We guarantee quality at every stage — from fruit selection and extraction to temperature controlled storage and shipment. Each batch is extracted with 24 hours after reception and undergoes strict quality checks before dispatch.

B.To can deliver up to 50 tonnes of Thaumatin arils in a year, depending on seasonal availabilty and client requirements, this quantity can slightly differ.

We sure do!
We supply fresh Thaumatin arils to international partners outside Africa.

We collaborate with over 100 local farmers, promoting fair wages, ethical labor, and eco-friendly harvesting practices to support both people and the environment.

All arils are kept under strict temperature-controlled conditions to preserve freshness, stability, and sweetness until they leave our warehouse. Just reach out if you require your order to be stored at a specific temperature.

It depends. We can provide evidence of export certifications upon request. However, product specifications can not be provided as we do not grow the fruits ourselves and these also greathly depends on the season of the year and the soil used for farming. We are nontheless open to sending samples to sustomers for quality check.
