Thermal processing is not only a preservation method — it’s a critical regulatory and safety requirement. For exporters, understanding the distinctions between different heat treatments is essential to ensure compliance with international standards such as Codex Alimentarius, EU regulations, FSIS, and APEDA guidelines.
Here’s a breakdown of the main heat treatment categories
Pasteurisation
Process: Moderate heat (typically 60–90°C) for a defined time to inactivate vegetative pathogens.
Objective: Reduction of microbial load while maintaining nutritional and sensory attributes.
Applications: Dairy, juices, egg products.
Export relevance: Pasteurised products must demonstrate validated time–temperature combinations and post-process handling controls to meet import country microbiological criteria.
Sterilisation / UHT Treatment
Process: Exposure to ≥110°C (often 121°C for canning or 135–150°C for UHT) to achieve commercial sterility.
Objective: Eliminate all viable microorganisms and spores.
Applications: Canned foods, shelf-stable milk, sauces.
Export relevance: Requires process validation, container integrity testing, and sterility assurance documentation to comply with destination country food safety authorities.
Cooking / Thermal Processing
Process: Controlled heating above 70°C (core temperature) depending on product type.
Objective: Achieve pathogen lethality (e.g., Listeria, Salmonella) while maintaining organoleptic quality.
Applications: Ready-to-eat seafood, meat, and plant-based meals.
Export relevance: Validation through microbial challenge studies and thermal profiling is often mandatory for approval in regulated markets.
Why Heat Treatment Compliance Matters
Each importing country enforces its own sanitary and phytosanitary (SPS) measures relating to heat treatment — including:
– Validated process schedules and thermal lethality documentation (F₀, P₀ values).
– Post-process handling protocols to prevent recontamination.
– Third-party certifications (e.g., ISO 22000, HACCP, BRCGS).
Failure to meet these requirements can result in border rejections, detentions, or product recalls, leading to financial and reputational risks.
How Amivet Exports Supports Exporters
✅ Develop and validate thermal process schedules compliant with target market regulations.
✅ Prepare technical documentation and process validation reports for export certification.
✅ Liaise with regulatory authorities and inspection agencies to streamline approvals.
✅ Conduct pre-shipment quality audits and ensure ongoing compliance across product categories.
