- Product Description
Bread Sodium Acetate Trihydrate - Food Grade Bakery pH Regulator & Preservative
At Shanxi Zhaoyi Chemical Co., Ltd., we manufacture premium Bread Sodium Acetate Trihydrate (CAS NO. 6131-90-4) specifically engineered for the bakery industry. With over 35 years of expertise since 1988 and an annual production capacity of 150,000 tons across our 27,000 m² facility, we deliver consistent quality that meets international food safety standards. Our product achieves ≥99.0% purity with heavy metals controlled below 2ppm, making it your reliable solution for rope spoilage prevention and dough pH optimization. The trihydrate form (CH3COONa·3H2O) dissolves rapidly at temperatures above 58°C, ensuring uniform distribution throughout your dough matrix while extending shelf life by 7-10 days at just 0.3%-0.5% addition rates.
Key Features & Benefits
The product solves critical challenges in commercial baking operations. You get effective rope spoilage control by inhibiting heat-resistant Bacillus subtilis bacteria that survive baking temperatures.
Our product maintains optimal pH levels between 4.5-5.5 without harsh acidity. This creates the perfect environment for yeast fermentation and gluten network development in your dough.
You'll experience extended shelf life of 7-10 days in high-moisture bakery products. The trihydrate crystalline structure dissolves quickly during mixing, distributing evenly throughout your formulation.
The mild acetic character won't overpower your bread's natural flavor profile. You can confidently use it in sweet breads, whole wheat varieties, toast, and savory applications.

How It Works?
Your dough benefits from multiple mechanisms when you add this trihydrate salt. The acetate ion acts as a conjugate base, forming a buffer system that resists pH changes during fermentation.
During mixing, the crystals dissolve rapidly in the aqueous dough phase. The released acetate ions create an acidic environment unfavorable to rope-forming bacteria while supporting beneficial yeast activity.
The buffering capacity stabilizes enzymatic activity throughout your fermentation window. Proteases and amylases work efficiently within this controlled pH range, developing optimal gluten structure and flavor compounds.
During baking, residual acetate continues to suppress bacterial spore germination. This protective effect extends into your product's shelf life, maintaining crumb integrity and freshness.
