When it comes to making delicious jerky, many people wonder if a dehydrator truly cooks the meat or just dries it out. The answer lies in understanding the science behind dehydration and the unique characteristics of a dehydrator. In this article, we’ll delve into the world of dehydrating and explore the process of making jerky, discussing the role of heat, moisture, and time in creating the perfect snack.
What is a Dehydrator, and How Does it Work?
A dehydrator is an electrical appliance designed to remove moisture from food, preserving it for later consumption. It works by circulating hot air around the food, causing the water molecules to evaporate. This process is similar to sun drying, but with a dehydrator, you have more control over the temperature, humidity, and air circulation.
Dehydrators typically consist of a heating element, a fan, and multiple trays for holding the food. The heating element warms the air, which is then circulated by the fan, ensuring even drying. The temperature and time settings can be adjusted to suit the type of food being dehydrated.
The Science of Dehydration
Dehydration is a complex process that involves the removal of moisture from food. When food is heated, the water molecules inside the cells turn into vapor and escape, causing the food to dry out. There are three stages of dehydration:
- Preheating: The food is heated to a temperature that allows the water molecules to turn into vapor.
- Constant rate period: The water molecules evaporate at a constant rate, causing the food to dry rapidly.
- Falling rate period: The water molecules evaporate more slowly, and the food continues to dry at a slower rate.
Does a Dehydrator Cook Jerky?
Now that we understand how a dehydrator works and the science behind dehydration, let’s address the question: does a dehydrator cook jerky? The answer is a bit more complicated than a simple yes or no.
When making jerky, the goal is to dry the meat to a point where it’s safe to eat and has a chewy texture. A dehydrator can help achieve this by removing excess moisture from the meat. However, the temperature and time settings used in a dehydrator are typically lower than those used in cooking.
In a dehydrator, the temperature is usually set between 135°F and 155°F (57°C and 68°C), which is lower than the temperature used in cooking. The low heat and air circulation help to dry the meat without cooking it. However, the heat can still cause some chemical reactions to occur, such as the denaturation of proteins and the breakdown of connective tissues.
The Role of Heat in Dehydrating Jerky
Heat plays a crucial role in dehydrating jerky, but it’s not the same as cooking. The low heat used in a dehydrator helps to:
- Denature proteins: The heat causes the proteins in the meat to unwind and reorganize, making the meat more tender and easier to chew.
- Break down connective tissues: The heat helps to break down the connective tissues in the meat, making it more palatable.
- Kill bacteria: The heat can help to kill bacteria and other microorganisms that may be present on the surface of the meat.
However, the heat used in a dehydrator is not enough to cook the meat thoroughly. The internal temperature of the meat may not reach a safe minimum internal temperature, which is 165°F (74°C) for beef, pork, and lamb, and 180°F (82°C) for poultry.
How to Make Jerky in a Dehydrator
Making jerky in a dehydrator is a relatively simple process that requires some basic ingredients and equipment. Here’s a step-by-step guide to making jerky in a dehydrator:

- Bowl
Preparing the Meat
Before dehydrating the meat, it’s essential to prepare it properly. Here’s how:
- Slice the meat: Slice the meat into thin strips, about 1/4 inch (6mm) thick.
- Marinate the meat: In a bowl, mix together the soy sauce, brown sugar, smoked paprika, garlic powder, and salt. Add the sliced meat and marinate for at least 30 minutes.
- Pat dry the meat: Remove the meat from the marinade and pat it dry with paper towels to remove excess moisture.
Dehydrating the Meat
Once the meat is prepared, it’s time to dehydrate it. Here’s how:
- Set the temperature: Set the dehydrator to 145°F (63°C).
- Place the meat: Place the meat strips on the trays, making sure not to overlap them.
- Dehydrate: Dehydrate the meat for 3-4 hours, or until it reaches the desired level of dryness.
Conclusion
In conclusion, a dehydrator does not cook jerky in the classical sense. Instead, it uses low heat and air circulation to dry the meat, making it safe to eat and giving it a chewy texture. The heat used in a dehydrator can cause some chemical reactions to occur, such as the denaturation of proteins and the breakdown of connective tissues. However, the heat is not enough to cook the meat thoroughly, and the internal temperature of the meat may not reach a safe minimum internal temperature.
By understanding the science behind dehydration and the unique characteristics of a dehydrator, you can make delicious jerky at home. Remember to always follow safe food handling practices and to cook the meat to a safe internal temperature if you’re unsure.
