L-Phenylalanine | Food & Pharma Grade Bulk Factory Supply (CAS 63-91-2

Why Global Importers Keep Sourcing L-Phenylalanine?
L-Phenylalanine is an essential amino acid with rigid demand in the food and pharmaceutical industry, which cannot be synthesized by the human body.
As an indispensable core precursor material for manufacturing Aspartame (low-calorie sweetener), it is also widely applied in medical amino acid infusions, functional foods and synthesis of peptide medicines. Sweetener manufacturers, health product factories and pharmaceutical companies maintain continuous purchasing all year round.
L-Phenylalanine with consistent stable quality can effectively improve the conversion rate of synthetic reactions, reduce by-products, cut production loss and overall manufacturing costs. It is the primary standard for buyers to select long-term suppliers. We adopt fermentation technology for production, strictly control heavy metals and related impurities, and our products meet import standards for food and pharmaceutical raw materials in multiple countries.

Frequently Asked Questions
Q1: Is L-Phenylalanine the primary raw material for Aspartame?
A: Yes. L-Phenylalanine and L-Aspartic Acid are two core raw materials for industrial Aspartame production. Its purity directly affects the conversion efficiency of finished products.
Q2: Can you provide samples for lab testing?
A: Samples are available for evaluation. We can arrange sample shipments as requested. Bulk orders can be negotiated after your lab test passes.
Q3: Does your product meet food and pharmaceutical import standards in Europe and America?
A: Complete test documents can be supplied. Our specifications comply with general standards of food grade and pharma grade to support customs review globally.
