Retort sterilization is an effective method for sterilizing edible bird nests, ensuring safety and extending shelf life. Here’s how to do it:
Retort Sterilization of Edible Bird Nest
- Preparation: Start by filling the jars with cleaned and prepared bird nest products, leaving some headspace. Seal the jars with sterilized lids.
- Preheat the Retort: Preheat the retort (a pressure cooker or specialized retort machine) to the desired temperature, usually around 121°C (250°F).
- Loading: Carefully place the sealed jars inside the retort, ensuring they’re evenly spaced to allow proper heat circulation.
- Sterilization Process: Heat the jars under pressure, typically at 15 PSI, for a specific time based on the product’s density and jar size (usually 30-45 minutes). This high-pressure heat kills bacteria and other pathogens.
- Cooling: After the sterilization cycle, gradually cool the jars within the retort to avoid thermal shock, which can cause breakage.
- Inspection: Once cooled, inspect the jars for proper sealing and store them in a cool, dry place.
