Dehydrating jerky at 155°F (68°C) is a popular method for ensuring food safety while achieving that desirable chewy texture. However, the exact drying time depends on several crucial factors. This guide breaks down everything you need to know to perfectly dehydrate your jerky every time.
Factors Affecting Jerky Dehydration Time at 155°F
Several variables influence how long it takes to dehydrate jerky at 155°F. Understanding these will help you achieve consistently delicious and safe results:
-
Thickness of the Jerky: Thicker cuts of meat require significantly longer drying times than thinner ones. Thinly sliced jerky (1/8" to 1/4") will dehydrate much faster than thicker pieces (1/4" to 1/2").
-
Type of Meat: Different meats have varying moisture contents. Leaner meats like venison or turkey will dehydrate faster than fattier meats like beef.
-
Meat Preparation: Properly trimming excess fat and ensuring even slicing will contribute to more even and faster dehydration. Marinades can also impact drying time, as some may add moisture.
-
Dehydrator Model and Airflow: The efficiency of your dehydrator plays a significant role. Models with better airflow will generally dry jerky faster. Overcrowding the dehydrator will also slow down the process.
-
Humidity and Ambient Temperature: High humidity and warmer ambient temperatures will increase drying time, while lower humidity and cooler temperatures will shorten it.
Estimating Dehydration Time at 155°F
While precise timing is impossible without considering the above factors, here's a general guideline:
- Thinly sliced jerky (1/8" - 1/4"): 6-12 hours
- Medium sliced jerky (1/4" - 3/8"): 12-18 hours
- Thickly sliced jerky (3/8" - 1/2"): 18-24 hours or more
Important Note: These are estimates. Always rely on the feel and appearance of the jerky to determine doneness, rather than solely on time.
Testing for Doneness: Crucial for Safe Jerky
Don't just rely on the timer! Use these methods to ensure your jerky is fully dehydrated and safe to eat:
-
The Bend Test: The jerky should be pliable but not sticky or bendy. It should feel leathery and slightly firm.
-
The Moisture Test: The jerky should be completely dry to the touch. There should be no moist areas or stickiness.
-
Internal Temperature: While not always necessary at 155°F, you can use a meat thermometer to verify an internal temperature below 145°F (63°C) to mitigate any potential food safety concerns, especially with thicker cuts.
Tips for Faster and More Even Dehydration
-
Pre-drying: Pat the meat slices thoroughly dry with paper towels before placing them in the dehydrator. This reduces initial moisture content.
-
Proper Spacing: Ensure adequate airflow between jerky pieces by arranging them in a single layer without overlapping.
-
Rotating Trays: Rotate the trays halfway through the drying process to ensure even dehydration.
-
Monitoring: Regularly check on your jerky throughout the process.
Conclusion
Dehydrating jerky at 155°F requires patience and attention to detail. By understanding the factors that influence drying time and utilizing the doneness tests, you can consistently produce safe, delicious, and perfectly dehydrated jerky. Remember, safety should always be your top priority—always err on the side of caution and ensure the jerky is thoroughly dry before consumption.
