- Product Description
Feed pH Adjustment Sodium Diacetate – Premium Feed Additive for Gut Health & Preservation
SHANXI ZHAOYI CHEMICAL CO., LTD brings you enterprise-grade Feed pH Adjustment Sodium Diacetate manufactured since 1988 with proven quality control. Our product contains precisely controlled acetic acid content of 38.0–41.0% and sodium acetate content of 57.0–60.0%, ensuring optimal buffering capacity at pH 4.5–5.0. With an annual production capacity of 150,000 tons across our 27,000 m² facility, we deliver consistent quality backed by ISO, KOSHER, and HALAL certifications. Our formula maintains heavy metal levels below 0.001% (Pb) and arsenic below 0.0003%, meeting stringent international feed-grade standards for safer animal nutrition.
Key Features & Benefits
Your feed formulation deserves a reliable pH modifier that goes beyond basic acidification. Our sodium diacetate offers dual-action performance combining antimicrobial protection with digestive optimization.
Unlike liquid acids that corrode equipment, this solid-state complex protects your mixing machinery while delivering superior gut health benefits. The 39.0–41.0% free acetic acid content releases gradually in the digestive tract, targeting harmful bacteria without overwhelming beneficial microflora.
You'll notice improved feed palatability, especially in swine diets where the mild vinegar aroma stimulates appetite. The buffering capacity (pKa 4.75) maintains stable pH conditions throughout digestion, enhancing nutrient absorption efficiency.
This white crystalline powder integrates seamlessly into existing feed formulations. Its non-hygroscopic handling characteristics simplify storage and reduce waste compared to liquid alternatives.

How It Works?
The mechanism behind this additive centers on controlled acid release throughout the digestive system. When you add it to feed, the compound remains stable during mixing and storage due to its solid crystalline structure.
Once ingested, the buffering system activates. In the stomach's low pH environment, it stabilizes gastric acidity without causing sharp fluctuations that stress young animals.
As digestion progresses to the small intestine, free acetic acid dissociates gradually. This creates an unfavorable environment for pathogenic bacteria like E. coli and Salmonella while preserving beneficial lactobacilli populations.
The sodium acetate component provides additional buffering capacity. It absorbs excess hydrogen ions during fermentation processes in the hindgut, preventing acidosis in high-energy diets.
This dual-phase action explains why you'll observe both immediate palatability improvements and long-term health benefits. The antimicrobial effect extends to stored feed, inhibiting mold growth for 2–3 times longer shelf life.

Applications
Swine Nutrition
You can incorporate 0.2–0.5% into nursery pig diets to combat post-weaning diarrhea. The vinegar note enhances feed acceptance during the critical transition period.
Poultry Feed
Broiler and layer rations benefit from 0.1–0.3% inclusion rates. It reduces bacterial load in the crop and gizzard, improving feed conversion ratios by 3–5%.
Aquaculture
Shrimp and fish feeds utilize 0.15–0.25% dosages. The product controls Vibrio species in water-stable pellets without leaching during submersion.
Ruminant Supplements
Calf starters and high-concentrate dairy rations use 0.1–0.2% to prevent ruminal acidosis. It stabilizes rumen pH during grain adaptation.
Feed Preservation
For stored grains and finished feeds with <13% moisture, apply 0.1–0.2% to inhibit mold growth. Higher moisture products may require up to 0.5% for effective preservation.
Pet Food Manufacturing
Premium dog and cat foods include 0.05–0.15% as a natural preservative alternative to synthetic chemicals, appealing to health-conscious consumers.

Packing

Manufacturing Process
Our generation starts with pharmaceutical-grade acidic corrosive and sodium carbonate. We source materials solely from certified providers with full quality documentation.
The response happens in jacketed stainless steel reactors beneath controlled temperature (45–55°C) and pH checking. This accuracy guarantees the target 38.0–41.0% acidic corrosive proportion without group variation.
Crystallization takes after in cooling tanks outlined for uniform molecule estimate dispersion. You get reliable 40–80 work powder that mixes effectively without isolation in bolster mixers.
After centrifugation and washing, the item experiences fluid-bed drying to accomplish <3% moisture content. Automated moisture analyzers reject any batch exceeding specifications.
Final screening removes oversized particles before metal detection and packaging. Our quality control laboratory tests every 5-ton batch for all specification parameters before release.
The entire process operates under GMP conditions with HACCP protocols. We maintain environmental controls preventing cross-contamination between product grades.
