Butterfly Pea vs Synthetic Blue Dye: The Clean-Label Case

Manufacturers replacing FD&C Blue No. 1 (Brilliant Blue FCF) with a plant source increasingly land on butterfly pea, and THS IMPEX LLP exports it (Clitoria ternatea, CAS 2055943-25-0) grown in Bareilly, Uttar Pradesh, India under HSN 0603. This is the clean-label comparison a formulator actually has to make, not a marketing slogan.

Natural anthocyanin vs certified synthetic

Brilliant Blue FCF is a petroleum-derived synthetic dye that requires FDA batch certification, whereas butterfly pea delivers its blue from anthocyanins and, as an extract, is listed under 21 CFR 73.69 as a colour additive exempt from certification. For a brand building a recognisable ingredient list, natural blue colourant from a single named botanical is the stronger clean-label story.

The regulatory tailwind

Regulatory pressure on synthetic dyes is real: the FDA revoked the authorisation for FD&C Red No. 3 in January 2025 and continues to scrutinise artificial colours. That pushes food and beverage manufacturers toward anthocyanin-rich botanicals such as butterfly pea at genuine commercial scale, which is the demand THS IMPEX supplies into across 50+ countries.

The trade-offs to plan for

A natural colourant is not a drop-in for a synthetic one. Butterfly pea is pH-sensitive, holding blue near neutral (about pH 6–7) and shifting purple to pink below pH 3, and it carries a subtle floral note a synthetic dye does not. THS IMPEX whole dried flowers, grown in Bareilly under HSN 0603 with an ORAC above 5000 μmol TE/g and a 24-month shelf life, let a formulator dial infusion strength to hit a target shade.

Sourcing the switch

THS IMPEX packs butterfly pea in 1 kg, 5 kg and 25 kg PP bags, dispatches within 7–10 business days, and traces every lot to Bareilly and GSTIN 36AAXFT6971E1ZF. To trial the switch from synthetic blue, request a sample or bulk quote at varshika@thsimpex.com or +91 8465819711.
