Analitik giriş
International trade in processed tomato products is a dynamic food-industry value chain. Hot Break vs. Cold Break defines pectin structure, rheology, color, and aroma. Cold break at 60–75°C allows controlled pectin hydrolysis — fluid paste, bright red color — ideal for tomato juice, soups, spray-dried powder, and low-viscosity sauces.
Iran operates vacuum evaporation and 220 L aseptic drums for EAEU and GCC markets. Procurement without rigorous COA (Bostwick, HMC, a/b) raises plant and customs risk.
1. Biochemistry: cold vs. hot break
PME and PG release on crushing. Hot break at 90–98°C preserves pectin networks; cold break lowers structural viscosity and protects lycopene and fresh aroma.
| Index | Cold break | Hot break |
|---|---|---|
| Pre-heater | 60–75°C | 90–98°C |
| Bostwick | 6–10 cm | 3–6 cm |
| a/b | > 2.1 | 1.9–2.1 |
| Evaporator Brix | 36–38% | 28–32% |
2. COA and physicochemical specs
NTSS 28–30 or 36–38%; Bostwick 6–10 cm @ 12.5 Brix; a/b ≥ 2.1; lycopene ≥ 50 mg/100 g; pH 4.0–4.4; HMC < 40%; burnt specks ≤ 5–7/10 g; heavy metals per destination.
3. Downstream applications
- Tomato juice and nectars
- Soups and consommés
- Fish in tomato sauce
- Spray-dried tomato powder
4. Iran production and exports
Southern, northwestern, and northeastern basins with complementary seasons; exports to Russia, Iraq, UAE, and CIS. Iranco aligns RFQs with export-grade plants.
5. Aseptic pack and storage
