Sodium Bicarbonate

Chemical name: Baking soda, bicarbonate of soda
CAS number: 144-55-8
Chemical formula: NaHCO3
Molecular weight: 84.01

Sodium Bicarbonate, baking soda, NaHCO3, CAS 144-55-8, is a white odourless crystalline powder with a salty taste, easily dissolved in water to a weakly alkaline solution and insoluble in ethanol. The food grade is supplied at 99.0-100.5% against GB 1886.2-2015 from an annual output of 100,000 tons. Beyond baking it has a distinct role in feed, where it buffers rumen acidity, supports calcium metabolism and helps animals shed heat load.

Why buyers specify this grade

Assay 99.0-100.5% against quality standard GB 1886.2-2015
Annual output of 100,000 tons, so volume supply is not a bottleneck
One material covering food leavening, beverage CO2 generation and feed buffering
Known solubility, 8.8% at 15 deg C and 13.86% at 45 deg C, for accurate solution make-up
HS code 2836300000 declared for customs

Quality control

Food grade released against GB 1886.2-2015 at 99.0-100.5%
TDS and MSDS issued with the order, sample COA on request

Where it is used

Leavening agent in the food industry and carbon dioxide generator in soda and cold drinks
Preservative for butter
Biscuit and cake leavening in combination with ammonium bicarbonate, at 20 g/kg in wheat flour
Solid refreshing beverages formulated with citric acid or tartaric acid to generate CO2
Acidity regulator and chemical leavening agent in general food use
Feed supplementation for sodium supply, calcium metabolism and heat stress relief

Who buys it

Bakeries and biscuit manufacturers
Beverage and effervescent powder producers
Dairy and butter processors
Feed mills and ruminant nutritionists
Poultry producers managing heat stress and eggshell quality

Problems it solves

Heat stress cutting intake and performance, where bicarbonate helps carry heat away as CO2 is released in the digestive tract
Thin eggshells where phosphorus levels are not held at the optimum
Rumen acidity and poor calcium metabolism in high-yielding animals
Effervescent drink powders that need a controlled CO2 source paired with a food acid

Packing and options

Food grade or feed application confirmed at order
Packing format confirmed at quotation

How it compares

Ammonium bicarbonate gives a stronger puff and leaves no residue, but releases ammonia. Sodium bicarbonate is gentler, contributes sodium and is safe in products where ammonia odour would be noticed. In biscuit and cake work the two are commonly formulated together.

Handling and storage

In wheat flour leavening the addition amount is 20 g/kg
Combine with citric or tartaric acid for solid refreshing beverages that generate CO2
Store dry and sealed, away from heat and moisture
In feed, dose against the ration and the heat-stress management plan

FAQ

Sodium Bicarbonate questions buyers ask

What assay and standard do you supply

Food grade sodium bicarbonate at 99.0% to 100.5% against quality standard GB 1886.2-2015.

How much is used in baking

As a leavening agent formulated with ammonium bicarbonate for biscuits and cakes, the addition amount in wheat flour is 20 g/kg.

Why is it added to animal feed

It supplies sodium to maintain blood sodium concentration, supports calcium metabolism, helps maintain the phosphorus level needed for eggshell formation, and releases CO2 in the digestive tract which carries away heat and helps the animal resist hot conditions.

How soluble is it

Easily dissolved in water at 8.8% at 15 deg C and 13.86% at 45 deg C, giving a weakly alkaline solution. It is insoluble in ethanol.

What is the HS code

2836300000.

Can you supply large volumes

Yearly output is 100,000 tons, so container and bulk quantities are routine.
