95% up Ascorbyl Palmitate 137-66-6

Functions of Ascorbyl Palmitate in Food Supplements

1. ‌Antioxidant Protection‌

Acts as a lipid-soluble antioxidant, preventing lipid peroxidation by scavenging free radicals.

Enhances oxidative stability of fat-containing products due to its fat-soluble nature.

2. ‌Vitamin C Supplementation‌

Provides a bioavailable, lipid-compatible form of ascorbic acid (vitamin C).

3. ‌Regulatory Compliance‌

Approved as a food additive (E 304i) in various regions, including China, for applications in food preservation and fortification.

Advantages of Sinoway’s Ascorbyl Palmitate

1. ‌Synthesis Methods‌

‌Enzymatic Biosynthesis‌: Utilizes microbial lipases (e.g., from Yarrowia lipolytica) to catalyze esterification of ascorbic acid with palmitic acid under controlled conditions.

‌Chemical Synthesis‌: Involves direct esterification or transesterification processes, often optimized for higher yield and purity.

2. ‌Purification & Stabilization‌

‌Nanosuspension Technology‌: High-pressure homogenization (HPH) with stabilizers like sodium dodecyl sulfate or polysorbate 80 to improve chemical stability and bioavailability.

3. ‌Regulatory Approvals‌

New food additive applications in China undergo technical evaluation by agencies like the National Health Commission (NHC) and China National Center for Food Safety Risk Assessment (CFSA).

Key Trends in China (2022–2025)

1. Increased focus on innovative production techniques (e.g., nanotechnology) to enhance functional properties.

2. Strict adherence to safety evaluations for food additives, particularly those used in infant formulas.
