Basic Parameters

Chemical Name: Sodium Bicarbonate
Molecular Formula: NaHCO₃
English Name: Sodium Bicarbonate / Baking Soda
Common Names: Baking Soda, Sodium Hydrogen Carbonate
CAS No.: 144-55-8
EC No.: 205-633-8
HS Code: 2836300000
Appearance: White crystalline powder, odorless, slightly salty, and alkaline
Properties: Aqueous solutions are weakly alkaline. Sodium bicarbonate begins to decompose at approximately 50°C and rapidly releases CO₂ when reacting with acids. It tends to cake when exposed to moisture.

Food Grade Sodium Bicarbonate

Standard: GB 1886.214 — National Food Safety Standard for Food Additive Sodium Bicarbonate

Food-grade sodium bicarbonate is subject to strict limits on heavy metals, including lead, arsenic, and cadmium, as well as other potentially harmful impurities. It is suitable for food and feed-related applications when used in accordance with applicable regulations and standards.

Main Applications

1. Food Processing

Baking Leavening Agent
Widely used in bread, biscuits, cakes, pastries, fried dough sticks, fried dough twists, and other baked or fried foods. When heated or reacted with acids, sodium bicarbonate releases carbon dioxide, helping dough rise and improving texture. It is commonly combined with citric acid, monocalcium phosphate, and other acidulants to produce baking powder.

Flour and Dough Processing
Used in steamed buns, noodles, dumpling wrappers, and other flour-based products. It can neutralize lactic acid and other organic acids produced during fermentation, helping improve color and texture while reducing sourness.

Meat Processing
Used as a meat tenderizing and processing aid. It can improve water-holding capacity and help produce a more tender texture. Applications include meatballs, sausages, and other processed meat products.

Fruit & Vegetable Processing
Used in fruit and vegetable washing and processing, as well as in certain color-protection and pH-adjustment applications. It can also be used in specific produce-cleaning processes.

Beverage & Fermentation Industries
Used as an acidity and pH regulator in carbonated beverages and fermented drinks. It can also be used for pH adjustment in brewing and other fermentation processes.

Seasonings & Pickled Foods
Used in sauces, marinades, and pickled foods to regulate acidity and alkalinity.

2. Drinking Water & Water Treatment

Food-grade sodium bicarbonate for water treatment can be used in drinking water applications to adjust pH and alkalinity and help improve water quality.

Applications include:

Tap water treatment

Bottled water processing

pH adjustment

Alkalinity adjustment

3. Feed Additive

Dairy and Beef Cattle:
Used as a rumen buffer to help maintain an appropriate rumen pH, reduce the risk of acidosis, and support normal milk production.

Poultry:
Used to help birds cope with heat stress and support normal eggshell quality.

Aquaculture:
Used to help regulate acid-base balance and maintain appropriate buffering capacity in feed or water, depending on the application.

4. Household & Daily-Use Applications

Sodium bicarbonate can be used for:

Fruit and vegetable washing

Dishware cleaning

Refrigerator deodorizing

Household cleaning formulations

5. Pharmaceutical & Personal Care Raw Materials

Used as a raw material in:

Mouthwash and oral-care products

Personal care and cleansing products

Certain pharmaceutical formulations

Important: Food grade does not necessarily mean pharmaceutical grade. Food-grade sodium bicarbonate must not be directly used as a pharmaceutical product or medicinal treatment unless it meets the applicable pharmaceutical standards and requirements.

Industrial Grade Sodium Bicarbonate

Industrial-grade sodium bicarbonate is manufactured for industrial applications and does not meet food-grade hygiene requirements. Compared with food-grade products, industrial-grade sodium bicarbonate generally has less stringent impurity and heavy-metal specifications.

Strictly prohibited for human consumption and must not be used in food or feed applications.

Industrial-grade sodium bicarbonate is manufactured according to applicable industrial standards and may contain higher levels of impurities than food-grade products.

Main Applications

1. Flue Gas Treatment & Deacidification

One of the major applications of industrial-grade sodium bicarbonate.

Widely used for dry and semi-dry flue gas desulfurization and deacidification in:

Power plants

Industrial boilers

Waste incineration plants

Other industrial emission-control facilities

Fine sodium bicarbonate powder is injected into the flue gas, where it reacts with acidic pollutants such as:

Hydrogen chloride (HCl)

Sulfur dioxide (SO₂)

Hydrogen fluoride (HF)

The resulting solid residues are relatively easy to collect and handle, making sodium bicarbonate an effective reagent for dry flue gas deacidification.

2. Wastewater Treatment

Used as:

A neutralizing agent for acidic wastewater

A pH adjustment agent

An alkalinity source in certain biological wastewater treatment systems

3. Rubber & Plastics Industry

Used as a foaming agent or auxiliary processing material in:

Rubber foaming

PVC production

Artificial leather manufacturing

Other polymer processing applications

4. Detergent & Chemical Industries

Used as a raw material or auxiliary ingredient in:

Industrial detergents

Washing powders

Compound cleaning agents

Industrial degreasing formulations

It can also be used to neutralize acidic components and assist in industrial cleaning processes.

Important: Industrial-grade sodium bicarbonate must not be used for cleaning tableware, food-contact surfaces, or other applications involving food contact unless the finished formulation is specifically approved for such use.

5. Fire Protection

Used as a raw material for certain dry chemical fire extinguishing agents, including BC-type dry chemical fire extinguishing powder.

6. Textile & Dyeing Industry

Used as a buffering and pH-regulating agent during textile dyeing and processing to help maintain stable dye-bath conditions.

It can also be used during textile washing and neutralization processes.

7. Leather Industry

Used in leather tanning, processing, and neutralization processes to adjust and control the pH of leather materials.

8. Mineral Processing & Metallurgy

Used as a pH regulator in mineral flotation processes and as an auxiliary material in certain metallurgical applications.

9. Other Industrial Applications

Industrial-grade sodium bicarbonate can also be used for:

pH adjustment in electroplating solutions

Industrial pipeline cleaning

Construction material additives

Chemical processing

Other industrial neutralization applications
