Quick Answer
Under-dehydrating jerky can lead to bacterial growth, foodborne illnesses, and a product that's not shelf-stable. Under-dehydration increases the risk of contamination and spoilage. It can also result in a jerky that's tough or chewy.
Insufficient Dehydration Risks
When jerky is under-dehydrated, the high moisture content creates an ideal environment for bacteria to grow. This can lead to foodborne illnesses, such as botulism, if the jerky is not stored properly. Staphylococcus aureus, E. coli, and Salmonella are common bacteria that can contaminate under-dehydrated jerky.
Dehydration Techniques for Jerky
To avoid under-dehydration, it’s essential to use a combination of temperature and time when dehydrating jerky. A temperature range of 135°F to 155°F (57°C to 68°C) is ideal for most meats. Dehydrating time can vary depending on the thickness of the meat, but generally, it takes 3 to 4 hours to dehydrate 1/4 inch thick slices of meat. It’s crucial to monitor the temperature and time to ensure proper dehydration.
Dehydrator Settings and Guidelines
For optimal results, use a food dehydrator set between 135°F and 155°F (57°C to 68°C). Monitor the jerky’s internal temperature to ensure it reaches 160°F (71°C) to prevent bacterial growth. If using a solar dehydrator, aim for a temperature range of 140°F to 150°F (60°C to 65°C). It’s essential to follow the manufacturer’s guidelines for specific dehydrator models, as some may have unique settings or requirements.
