A tomato paste certificate of analysis (CoA) is a critical document that provides detailed information about the quality and safety of tomato paste. It allows buyers, manufacturers, and distributors to verify whether a batch meets both industry standards and specific buyer requirements.
Here is an example based on a 36–38% Brix cold break tomato paste:
1. Product Overview
| Parameter | Value |
|---|---|
| Date of Production | 21.08.2025 |
| Date of Expiry | 21.08.2027 |
| Brix % | 36.77 |
| Bostwick (cm/30s) | 8.0 |
| Lycopene (mg/100g) | 76 |
| A/B | 2.3 |
| pH | 4.23 |
| Total Acid (%) | 6.52 |
| HMC | 19 |
These specifications represent a high-concentration cold break tomato paste, suitable for sauces, condiments, and food processing applications requiring thicker consistency and higher color stability.
2. Understanding Key Quality Parameters
Brix %
- Indicates total soluble solids.
- 36–38% Brix: Concentrated paste, thicker, suitable for industrial applications.
- Lower Brix: thinner paste, suitable for soups or beverage applications.
Bostwick Consistency
- Measures flow rate (cm/30s).
- Example: 8.0 cm/30s indicates medium viscosity; lower values = thicker paste, higher values = more fluid.
Lycopene Content
- Determines color and antioxidant properties.
- Typical range: 60–80 mg/100g for high-quality concentrated tomato paste.
- Our example: 76 mg/100g, indicating rich red color.
pH & Total Acidity
- pH 4.2–4.5 ensures microbial stability.
- Total acid 5–7% for proper flavor balance and shelf life.
A/B Ratio
- Reflects the color balance of red pigments.
- Typical range: 2.0–3.0; 2.3 is within ideal range.
3. Microbiological Safety
| Test | Result | Standard |
|---|---|---|
| Coliforms | Not Detected | <10/g |
| Salmonella | Not Detected | Negative |
| Total UFC | <100/g | <100/g |
| Yeasts & Molds | <100/g | <100/g |
These results indicate excellent microbiological safety, suitable for both industrial use and consumer products.
4. Heavy Metal Limits
| Metal | Result | Maximum Limit |
|---|---|---|
| Copper (Cu) | <10 mg/1000g | 10 mg |
| Lead (Pb) | <1.0 mg | 1.0 mg |
| Arsenic (As) | <0.5 mg | 0.5 mg |
| Mercury (Hg) | <0.2 mg | 0.2 mg |
The batch meets all standard heavy metal safety requirements.
5. How to Use a Tomato Paste CoA to Verify Your Product
When reviewing a certificate of analysis:
- Check Brix %: Ensure the concentration matches your formula.
- Compare viscosity and flow: Bostwick and HMC values indicate processing behavior.
- Assess color and lycopene: Verify consistency with desired color.
- Confirm pH and acidity: Ensure stability and safety.
- Review microbiology & heavy metals: Verify compliance with regulations.
If all indicators fall within typical ranges, the product can be considered compliant and suitable for your application.
