When purchasing sodium bicarbonate (baking soda) for industrial, food, feed or cosmetic production, two core parameters determine your final product performance: purity grade and particle size / mesh. Wrong selection will cause unstable reaction, poor mixing, extra cost or non-compliance issues. This guide helps global buyers pick the right sodium bicarbonate according to their production workflow.
1. Choose the Right Purity Grade Based On Industry & Compliance
Purity defines impurity limits, heavy metal content and regulatory certification. Never mix grades across different industries.
Food Grade Sodium Bicarbonate (≥99.0%) Meets FCC / E500 standard. Strict control on heavy metals, arsenic and chloride. For bakery, beverage, food processing, fruit & vegetable washing. Mandatory for all food-contact production lines.
Feed Grade Sodium Bicarbonate (≥98.5%) Specially designed for ruminant animal feed. Used as a rumen buffer for dairy cows and sheep. Balances stomach pH and improves feed utilization. Cost-effective for livestock farms.
Industrial Grade Sodium Bicarbonate For environmental protection, flue gas desulfurization, sewage pH adjustment, soda blasting, rubber & textile processing. Higher impurity tolerance, competitive bulk price for large-volume non-food projects.
Pharma Grade Sodium Bicarbonate (≥99.5%) Ultra-low heavy metals, follows USP standard. For antacids, effervescent tablets and medical auxiliary materials. Required for pharmaceutical manufacturing.
Key tip: Higher purity does not always equal better value. Pick the minimum qualified grade to meet your regulatory requirements and control raw material cost.
2. Select Particle Size (Mesh) By Reaction Speed & Mixing Demand
Particle size directly impacts dissolution speed, reaction rate, flowability and dust level.
Ultra-fine powder (150–200 mesh) Fast dissolving, excellent uniform dispersion. Ideal for cosmetics, fine food additives, pharmaceutical excipients. Good for liquid mixing and low-residue formulations.
Fine powder (80–120 mesh) Most popular food grade size. Widely used in bakery, biscuits, beverage production. Mix evenly with flour and release CO₂ steadily during heating.
Medium granules (40–70 mesh) Balanced flowability and dissolution. Mainly for feed additives. Less dust during automatic feeding, easy mixing with feed raw materials.
Coarse granules (20–40 mesh) Slow reaction speed, low caking risk. Best for flue gas treatment, water treatment and soda blasting. Larger particles extend contact time with waste gas or wastewater.
Key tip: If your production line has spraying, continuous reaction or dry mixing processes, we can customize particle distribution according to your technical sheet.
3. Common Mistakes When Buying Sodium Bicarbonate
Blindly choosing high-purity grade for industrial use, raising unnecessary raw material cost.
Using coarse granules for food production: poor dispersion, uneven leavening effect.
Using industrial grade for food/feed: fails safety inspection, triggers compliance risks.
Ignoring particle distribution: wide size range causes unstable batch performance.
