I. Learn about the freeze drying process
Freeze drying is a method of food preservation that involves freezing at very low temperatures and then removing water from the food by sublimation. Sublimation is the process of turning a solid directly into a gas without going through the liquid phase. This means that the water in the food changes from ice to vapor without melting. This preserves the food’s texture, flavor and nutrients without reducing its quality or shelf life.
Freeze-drying is the ideal method for preserving strawberries because it retains most of the strawberries’ original properties. Freeze-dried strawberries have the same color, taste and nutritional value as fresh strawberries but have a longer shelf life and lighter weight. Freeze-dried strawberries can last up to 2 years when stored properly in an airtight container with an oxygen absorber¹. They can also be rehydrated easily by adding water or other liquid.
FruitBuys Vietnam uses advanced drying technology to produce high quality freeze-dried strawberries, meeting international standards. They use three types of drying technology: Air Drying (AD), Freeze Drying (FD) and Vacuum Frying (VF). Each technology has its own advantages and disadvantages depending on the type of fruit and the desired result. For freeze dried strawberries, they use FD technology, which is the most effective and efficient way to preserve the freshness and flavor of strawberries without adding any preservatives, additives or sugar any.
II. Prepare strawberries for freeze drying
Before freezing dried strawberries, you need to prepare them properly. This involves choosing the right strawberries, washing them and slicing them:
*Choose the Right Strawberries
The quality of frozen strawberries depends largely on the quality of fresh strawberries. You want to choose strawberries that are ripe, fresh, bright red and have a sweet scent. You also want to avoid bruised, moldy, or overripe strawberries that can affect the flavor and texture of the final product.
FruitBuys Vietnam has a strict quality control system, ensuring they only use high-quality fresh strawberries for freeze-drying. They source their strawberries from local farmers who grow them organically and naturally. They also test each batch of strawberries before processing to ensure they meet standards.
*Wash and slice
After choosing fresh strawberries, you need to wash them and slice them. Washing them will remove any dirt or debris that may be on their surface. Slicing them will make them easier to freeze-dry and rehydrate later. To wash strawberries, simply rinse them under cold water for about 30 seconds. Then dry them with a clean towel or paper towel. To cut strawberries, use a medium or small knife to cut off the green stems and brown spots. Then cut them lengthwise into thin slices about 1/4 inch (0.64 cm) thick. Try to make the slices as uniform as possible so they dry evenly.
III. Freeze drying process: Step by step
Once you’ve prepared your fresh strawberries, you’re ready to freeze-dry them. This involves freezing them, putting them in a freeze dryer, setting the drying time and temperature, and then packaging them.
The first step in freeze drying is freezing your sliced strawberries. This is done by placing them in a freezer at a temperature below -40°F (-40°C) for at least 24 hours. This ensures that all the water in the strawberries is frozen solid. Freezing is crucial in freeze drying because it prevents the formation of ice crystals that can damage the cell walls of the fruit.
It also reduces the amount of energy needed for sublimation later. FruitBuys Vietnam has state-of-the-art freezers that can freeze large quantities of sliced strawberries quickly and efficiently. They also monitor the temperature and humidity levels in their freezers to ensure optimal freezing conditions.
*Loading the Freeze Dryer
The next step is loading your frozen strawberries into the freeze dryer. This is done by placing them on trays that are lined with parchment paper or freezer paper. This prevents the strawberries from sticking to the metal surface of the trays. You want to spread your strawberries on the trays in a single layer without overlapping them. You also want to leave some space between each strawberry for better air circulation. FruitBuys Vietnam has large-capacity freeze dryers that can accommodate up to 1000 kg of frozen strawberries per batch. They also have different shapes and sizes of trays to suit different types of fruit.
*Drying Time and Temperature
The third step is setting the drying time and temperature for your freeze dryer. This is done by using a control panel that allows you to adjust the settings according to your preferences. The drying time and temperature depend on the type and quantity of fruit you are freeze drying. For strawberries, the recommended drying time is about 24 hours and the recommended drying temperature is about -50°F (-45°C).
The drying process involves creating a vacuum inside the freeze dryer that lowers the air pressure and allows the water in the strawberries to sublimate. The water vapor is then collected by a condenser and drained out of the freeze dryer. FruitBuys Vietnam has precise and accurate control panels that allow them to adjust the drying time and temperature for each batch of strawberries. They also have sensors and indicators that monitor the progress and status of the drying process.
*Packaging the Freeze Dried Strawberries
The final step is packaging your freeze dried strawberries. This is done by removing them from the trays and placing them in airtight containers with oxygen absorbers. This prevents moisture and oxygen from entering the containers and spoiling your strawberries.
Packaging is important in freeze drying because it preserves the freshness and quality of your strawberries for a long time. It also makes them easier to store and transport. FruitBuys Vietnam has various packaging options for their freeze dried strawberries, such as bags, boxes, cans, or jars. They also have different sizes and weights to suit different needs and preferences.
Freeze drying strawberries is an art that requires skill, knowledge, and technology. It involves preparing fresh strawberries, freezing them, loading them into a freeze dryer, setting the drying time and temperature, and packaging them. Freeze drying preserves the natural flavor, color, and nutrition of fresh strawberries without adding any preservatives, additives, or sugar. It also extends their shelf life and reduces their weight.

FAQs-People also ask:
How can I freeze dry strawberries at home?
You can freeze dry strawberries at home if you have a home freeze dryer or an oven. A home freeze dryer is a device that can freeze dry food at home using the same process as commercial freeze dryers. An oven is a less efficient but cheaper alternative that can mimic the freeze drying process by using low heat and air circulation. However, both methods require time, space, and energy to produce freeze dried strawberries at home.
Can I freeze dry strawberries in my freezer?
No, you cannot freeze dry strawberries in your freezer. Freezing is only the first step of freeze drying. You also need to create a vacuum and lower the air pressure to allow the water in the strawberries to sublimate. Your freezer cannot do this. If you leave your strawberries in your freezer for too long, they will become freezer burned and lose their quality and flavor.
Why are my freeze dried strawberries soggy?
Your freeze dried strawberries may become soggy if they are exposed to moisture or humidity. To prevent this, you should store them in airtight containers with oxygen absorbers in a cool and dry place. You should also avoid opening and closing the containers frequently or leaving them out for too long.
