Ascorbic Acid Granulation 97%--Sunway (Hangzhou) Biotechnology Co., Ltd.

Overview

Product Overview & Core Technical Identity

SUNWAY supplies premium Ascorbic Acid Granulation 97 (97 SF, Direct Compressible Vitamin C Granule) sourced from NHU COVITAS, fully compliant with internal enterprise standard NHU/HLJSTPZBQC329, FCC and USP specifications. This free-flow coated VC granule adopts HPMC slow-release coating technology, effectively reducing dust generation and inhibiting oxidation discoloration during production, storage and high-temperature processing. Compared with common fine VC powder, it features superior flowability, low hygroscopicity and excellent direct tableting performance, widely applied in chewable tablets, compound nutrition granules, feed premixes and functional food systems. Every batch completes full physical, chemical and microbial comprehensive testing, with 12-month sealed sample retention to realize complete quality traceability. Mixed consolidated shipment with sodium ascorbate, calcium ascorbate and other vitamin derivatives is supported to cut customers' integrated procurement and logistics costs.

Functions

Physiological Functions & Industry Application Logic

Ascorbic Acid Granulation 97 retains complete biological activity of natural Vitamin C, while solving the inherent drawbacks of common fine VC powder such as dusting, easy deliquescence and fast oxidation:

Core Vitamin C Nutritional Activity Participate in human collagen synthesis, boost immune function, accelerate wound repair, promote iron absorption and eliminate free radicals to prevent scurvy. The granulated coated structure reduces gastrointestinal irritation compared with raw VC powder.

Excellent Processing Performance for Tableting Uniform granularity and ideal bulk density deliver outstanding flowability, no segregation during mixing with minerals and multi-vitamins; low dust avoids workshop pollution, perfectly adapted for direct compression of chewable VC tablets and compound nutrition granules without extra binders.

Enhanced Anti-Oxidation & Thermal Stability HPMC coating layer isolates VC from air, moisture and light, effectively slow down discoloration and potency loss during high-temperature granulation, baking and long-term shelf storage, superior to uncoated VC powder.

Livestock Anti-Stress Fortifier Slow-release granule form maintains stable VC activity in feed premix for long storage; relieve breeding & transportation oxidative stress of poultry, swine and aquatics, improve eggshell quality and juvenile survival rate.

Food Anti-Browning Stabilizer Used in baked goods, nutrition powder and solid drinks to inhibit enzymatic browning of fruit raw materials, retain natural color without sour taste interference on finished products.

Key Property Reminder: Although coated for stability, long-term exposure to strong sunlight, high humidity and heavy metal ions will still trigger gradual activity attenuation after unpacking.
