As a Chinese tomato paste exporter rooted in Xinjiang’s golden tomato growing belt, we have developed our exclusive 3-step sterile locking process that keeps fresh tomato flavor fully preserved even after 6 months of transoceanic transport. This breakthrough is breaking the long-standing stereotype among global buyers that long-distance shipping will inevitably damage the quality of canned tomato products.
Our 3-Step Sterile Flavor Locking System
1. 3-Second Instant Ultra-High Temperature Sterilization
We abandoned the traditional 20-minute prolonged sterilization method that damages nutrients. Our freshly pulped tomato material is heated to 137°C for no more than 3 seconds. This eliminates all harmful microorganisms while retaining over 90% of the original vitamin C and natural lycopene that would be destroyed in long-time heating.
2. Full Positive Pressure Aseptic Filling
Our entire filling workshop maintains 10Pa positive pressure filtered sterile air, which completely blocks external bacteria from entering the production line. Every piece of packaging material goes through ultraviolet disinfection and hot water rinsing before touching our tomato paste, making sure no secondary pollution happens during canning.
3. Residual Oxygen Controlled Below 0.3%
Before sealing every can, we pump out all residual oxygen inside the container, bringing the internal residual oxygen rate down to less than 0.3%. This step effectively stops oxidative deterioration during long sea voyages, so our tomato paste will never develop stale or metallic off-flavors even after half a year on the ocean.
Verified Performance With Our Global Clients
Since we fully applied this new process in 2024, we have delivered over 120 containers of this tomato paste to markets across the European Union, South Africa, Southeast Asia and the Middle East. Third-party sampling tests we arranged after 6 months of ocean transportation show that our product’s flavor retention rate reaches 94%, far higher than the 72% average level of traditional tomato paste products in the international market.
Frequently Asked Questions
- Q: Does this 3-step process raise your production costs a lot?
A: Our overall production cost only increases by around 6%, but it reduces the return rates caused by flavor deterioration for our overseas customers by over 90%, bringing much higher long-term supply chain value for importers. - Q: Can this technology work for different packaging sizes?
A: Absolutely. Our system supports full compatibility from 70g consumer glass jars to 220kg industrial aseptic bags, covering all mainstream packaging specifications in the global tomato sauce trade. - Q: Do you add any extra preservatives or additives in this process?
A: No, we rely entirely on physical sterilization and oxygen control for the whole process. Our finished product contains no artificial preservatives, artificial colors or synthetic flavorings, and it fully meets EU food safety standards. - Q: How does Xinjiang’s raw material advantage work with this process?
A: The processing tomatoes we source locally have high natural solid content and low water activity. When combined with our 3-step sterile system, the natural flavor foundation of our product is far more stable than those made from diluted raw materials. - Q: What is the minimum order quantity for this flavor-locking version of your tomato paste?
A: Our minimum MOQ is 1 × 20ft container. We also welcome buyers to arrange a 200kg sample batch for flavor verification before placing a formal bulk order. - Q: Can you provide third-party test reports to prove the 6-month flavor retention effect?
A: We can provide you with complete test data including flavor comparison reports, microbial inspection certificates and residual oxygen detection records issued by authorized international food testing institutions.
