Sodium Ascorbate--Sunway (Hangzhou) Biotechnology Co., Ltd.

Overview

Product Overview & Core Technical Identity

SUNWAY supplies premium Food Grade Sodium Ascorbate (Vitamin C Sodium Salt, E301) fully compliant with GB 1886.44-2016 Premium Grade, USP, JECFA and FCC monographs. It is a neutral buffered water-soluble vitamin C derivative synthesized via standardized recrystallization process, featuring mild weak alkaline pH, superior oxidation resistance compared to pure L-Ascorbic Acid, and high water solubility without strong sour irritation. Our material adopts strict heavy metal and solvent control system, stable batch purity, and full-index HPLC testing for every batch, with 12-month sealed sample retention to realize full quality traceability. Mixed consolidated shipment with calcium ascorbate, vitamin series and mineral raw materials is available to reduce customers' integrated procurement and logistics expenses.

Functions

Physiological Functions & Industry Application Logic

Sodium Ascorbate is a neutral buffered form of Vitamin C with identical nutritional activity as L-Ascorbic Acid, overcoming the strong acidity defect of pure VC and delivering dual values of nutritional fortification and food anti-oxidation:

Complete Vitamin C Physiological Activity Participate in human collagen synthesis, boost immune cell activity, accelerate wound repair, promote iron absorption, resist free radical oxidative damage, and prevent scurvy. The buffered sodium salt form causes less gastric irritation for sensitive stomach populations.

Neutral Anti-Browning Food Preservative Weak alkaline aqueous system will not acidify protein, dairy and fruit formulas; effectively inhibit enzymatic browning of fruits, vegetables and meat products, restrain lipid peroxidation to extend shelf life of baked goods, beverages and cured food.

Stable Nutritional Fortifier Less prone to discoloration and potency loss during high-temperature sterilization, baking and long-term storage than pure ascorbic acid; suitable for neutral/weak alkaline nutritional powder and chewable tablet formulas.

Livestock Anti-Stress Additive Supplement VC nutrition for poultry, swine and aquatics, relieve breeding & transportation oxidative stress, improve eggshell quality, animal fur gloss and juvenile survival rate, delay feed rancidity.

Mild Cosmetic Antioxidant Raw Material Neutral pH avoids skin acid irritation, scavenge UV-induced free radicals, brighten dull skin and support epidermal collagen regeneration in skincare toners and lotions.

Key Property Reminder: Although more stable than L-Ascorbic Acid, long-term exposure to strong light, high humidity and heavy metal ions will trigger yellowing and activity attenuation of sodium ascorbate powder.
