1. For Animal Feed & Gut Health: Sodium butyrate (CAS 156-54-7) is a widely used feed additive that supports intestinal health in poultry, swine and ruminants, promoting villus development, gut barrier function and nutrient absorption for improved growth performance.
2. For Feed Acidification & Palatability: As a short-chain fatty acid salt, sodium butyrate helps lower intestinal pH and improves feed intake and digestibility in animal diets, supporting intestinal environment balance in livestock and aquaculture production.
3. For Food Flavoring Applications: Food-grade sodium butyrate serves as a flavoring additive and raw material for butter-type flavor esters, supporting flavor development in processed foods, snacks and seasoning applications.
4. For Chemical Intermediates & Esters: Sodium butyrate is an intermediate for producing butyric acid esters and butyrate derivatives used in flavors, fragrances and fine chemical synthesis.
5. Consistent Quality For Global Industry: Supplied as high-purity white crystalline powder in feed, food and industrial grades with consistent quality and flexible packaging, sodium butyrate gives feed, food and chemical manufacturers a dependable short-chain fatty acid salt with stable supply.
