That process not only increases the shelf life of food but concentrates flavor and nutrients removing moisture. An advanced food dehydrator allows you to quickly and easily convert almost any food into a healthy snack or meal, while simultaneously recycling food waste. Here’s the science behind food dehydration and how it preserves nutrients and flavors.
What is Food Dehydration?
Food dehydrating is the process of removing moisture content from food products to make them last longer. Moisture is a breeding ground for bacterial, mold, and yeast growth, all of which can spoil your food. It starves the food of moisture and freezes to kill any chance of microbial action. This method has been used for centuries to preserve everything from fruits and vegetables to meats, through sun-drying, air-drying, and a variety of other methods. Food dehydrators in the modern day have transformed this process by using a controlled environment with proper temperature and airflow settings. They can also offer you other useful tools for dehydrating foods, including fruits and vegetables, meat, and herbs, at home while preserving their flavors and textures.
The Science Behind Food Dehydration
Water activity and controlled application of heat are the scientific principles behind food dehydration. Water molecules are trapped within the structure of the food so that when heat is applied during a certain process, the molecules evaporate without cooking or ruining the food.
- Temperature Control: Dehydrators operate at low temperatures (typically around 70°F and 190°F) to slowly remove moisture without losing nutrients and flavor.
- Air Circulation: One fan ensures even distribution of the warm air on all trays to avoid uneven drying, drying out, and spoilage.
- Moisture Removal: As water vaporizes, it is vented out from the dehydrator. Septree’s dehydrators are equipped with advanced ventilation systems that effectively remove moisture, ensuring uniform drying conditions.
Food dehydrators achieve this balance, as they are designed to preserve the nutritional values of foods while these are already maximizing the shelf life and taste.
Nutritional Advantages of Dehydrated Foods
Dehydrated foods are truly beneficial from a nutritional standpoint and make for healthier alternatives to other preservation methods, such as freezing and canning.
- Vitamin Retention: By using low-temperature dehydration, important vitamins like A and C can be preserved that would otherwise be damaged in high-heat cooking processes.
- No Additives: Unlike commercial-grade processed foods, dehydrated snacks don’t need preservatives or chemical additives.
- Nutrient Density: Evaporating liquid squeezes nutrients into a smaller packet. Dried fruits, for example, dates, apricots, raisins, and figs are high in natural sugars and fiber making them great for a quick energy boost.
With a high-quality dehydrator, like Septree’s 10-tray model, you’ll be able to make bulk amounts of healthy, nutrient-rich snacks that are as tasty as they are good for you.
How Do Modern Food Dehydrators Work
Most modern food dehydrators are intended to remove moisture from the foods while keeping them at a temperature that will not ruin the quality and nutritional values. Here’s how they work:
- Heating Element: The dehydrator’s heating element heats the air in the unit to a controlled temperature.
- Fan Circulation: A fan circulates warm air on all trays to facilitate uniform drying.
- Ventilation System: Moist air exits through vents strategically positioned, eliminating condensation.
- Digital Controls: More advanced models, such as Septree’s 6-tray fruit dehydrator, include adjustable temperature settings (70°F–190°F) and timers for more accuracy.
These features help you dehydrate a wide variety of foods, from herbs and spices to jerky and fruit leathers, and achieve the best results.
How to Pick the Right Food Dehydrator
The choice of the right dehydrator will depend on your needs and preferences. Here are some things to keep in mind:
- Material: Stainless steel insides are more durable and sanitary than plastic
- Capacity: Compact models such as Septree’s 4-tray mini dehydrator are great for small families or occasional use, while more massive 10-tray models are best for bulk processing.
- Easy of Use: Features such as digital controls, adjustable temperature settings, and trays that are safe for the dishwasher can make use of the appliance easier.
- Noise level: You also want a quiet model if you leave your dehydrator running overnight.

Creative Ways to Use Your Food Dehydrator
A food dehydrator isn’t only useful for preserving fruits and vegetables, it’s also a tool for endless culinary possibilities:
- Homemade Snacks: Make healthy snacks such as apple chips, banana slices, or kale crisps.
- Jerky Preparation: You can make jerky from beef or turkey—just use your favorite marinades.
- Herbs & Spices: Dried herbs like basil or mint for cooking year-round.
- Fruit Leathers: Make fruit purees dehydrate them, and roll them into snacks that will make children and adults happy.
- Pet Treats: Bring your pets all-natural snacks by dehydrating sweet potatoes or chicken strips for pets.
