Why It Matters
Tofu makers and the fast-growing plant-protein sector buy glucono-delta-lactone, calcium sulfate and calcium chloride as protein coagulants and firming agents to set soy and other plant-protein gels. Demand grows as plant-based manufacturing scales
Solution Approach
Tofu makers and the fast-growing plant-protein sector buy glucono-delta-lactone, calcium sulfate and calcium chloride as protein coagulants and firming agents to set soy and other plant-protein gels. Demand grows as plant-based manufacturing scales RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Formulation Workflow
1
Process & Compliance Review
Map the application and contact points, and confirm food-grade and regulatory status (FCC/USP, Kosher/Halal, allergen) for every input.
2
Ingredient & Grade Selection
Select the right grade of acidulant, preservative, emulsifier, stabilizer, or processing aid for the formulation, label, and sensory targets.
3
Bench Trial & Dosing
Validate use level and performance in a bench or pilot batch, and specify packaging and lot traceability suited to food-safety requirements.
4
Quality & Shelf-Life Validation
Verify finished-product quality, microbial stability, and shelf life, and lock the spec with a CoA and document control for audits.
Recommended Chemistries (3)
Glucono Delta-Lactone (GDL)
CAS 90-80-2
