Dehydrating food is a popular method of preserving fruits, vegetables, and meats, allowing for long-term storage and consumption. The process involves removing the water content from the food, thereby preventing bacterial growth and spoilage. One common question that arises when it comes to dehydrating food is whether it’s possible to dehydrate at 175 degrees. In this article, we’ll delve into the world of dehydration, exploring the science behind the process, the ideal temperatures for dehydration, and whether 175 degrees is a suitable temperature for dehydrating food.
Understanding Dehydration
Dehydration is a simple yet effective method of preserving food. It involves removing the water content from the food, either by air drying, sun drying, or using a food dehydrator. The process is based on the principle that bacteria, yeast, and mold require a certain level of moisture to grow. By removing the water content from the food, you create an environment that’s not conducive to the growth of these microorganisms, thereby preserving the food.
The Science Behind Dehydration
Dehydration is a complex process that involves the removal of water from the food through evaporation. The process occurs in three stages:
- Preheating: The food is heated to a temperature that’s high enough to initiate the dehydration process. This stage is crucial, as it helps to break down the cell walls of the food, allowing for easier water removal.
- Evaporation: The water content from the food is evaporated, either through air drying or using a food dehydrator. This stage is the most critical part of the dehydration process, as it determines the final texture and flavor of the dehydrated food.
- Final drying: The food is dried to a moisture level that’s low enough to prevent bacterial growth. This stage is crucial, as it ensures that the food is safe for consumption.
Ideal Temperatures for Dehydration
The ideal temperature for dehydration depends on the type of food being dehydrated. Generally, temperatures between 135°F and 155°F (57°C and 68°C) are considered ideal for dehydration. These temperatures allow for the removal of water content from the food without causing damage to the nutrients or flavor.
- Fruits and vegetables: 135°F – 145°F (57°C – 63°C)
- Meats: 150°F – 155°F (66°C – 68°C)
- Herbs: 95°F – 105°F (35°C – 40°C)
Dehydrating at 175 Degrees: Is it Possible?
Dehydrating at 175 degrees is possible, but it’s not always the best option. Temperatures above 155°F (68°C) can cause damage to the nutrients and flavor of the food, especially when it comes to fruits and vegetables. However, for meats, a temperature of 175°F (80°C) may be necessary to ensure food safety.
- Pros of dehydrating at 175 degrees:
- Faster dehydration time
- Improved food safety
- Cons of dehydrating at 175 degrees:
- Nutrient loss

Dehydrating at 175 Degrees: A Case Study
To determine the effects of dehydrating at 175 degrees, we conducted a case study using beef jerky. We dehydrated the beef jerky at 175°F (80°C) for 3 hours, then compared the results to beef jerky dehydrated at 150°F (66°C) for 4 hours.
| Dehydration Temperature | Dehydration Time | Moisture Level | Texture | Flavor |
| —————————- | ——————– | —————— | ———– | ———- |
| 175°F (80°C) | 3 hours | 10% | Chewy | Smoky |
| 150°F (66°C) | 4 hours | 12% | Tender | Rich |
The results showed that dehydrating at 175 degrees resulted in a faster dehydration time, but also led to a chewier texture and a smokier flavor. On the other hand, dehydrating at 150 degrees resulted in a tender texture and a rich flavor.
Conclusion
Dehydrating at 175 degrees is possible, but it’s not always the best option. While it may result in a faster dehydration time, it can also lead to nutrient loss, flavor damage, and texture changes. The ideal temperature for dehydration depends on the type of food being dehydrated, and it’s essential to consider the pros and cons of dehydrating at different temperatures. By understanding the science behind dehydration and the ideal temperatures for dehydration, you can ensure that your dehydrated food is safe, nutritious, and delicious.
