Product Introduction
Freeze-dried sugared strawberry granules are a delightful and convenient way to enjoy the taste and nutritional benefits of fresh strawberries, all year round. These granules are made by freeze-drying real strawberries and coating them with a light layer of sugar, resulting in a crunchy texture and concentrated flavor. The freeze-drying process preserves the natural vitamins, minerals, and antioxidants found in strawberries, while the sugar adds a touch of sweetness that enhances their palatability. This product offers a versatile ingredient for various culinary applications, from breakfast cereals to decadent desserts.
Production Process
The production of freeze-dried sugared strawberry granules involves several key steps:
- Selection and Preparation: Fresh, ripe strawberries are carefully selected and thoroughly washed to remove any impurities.
- Slicing: The washed strawberries are then sliced into small, uniform pieces to facilitate efficient freeze-drying.
- Sugaring: The strawberry slices are lightly coated with sugar to add sweetness and contribute to the final texture.
- Freezing: The sugared strawberry slices are rapidly frozen to a very low temperature, typically around -40°C (-40°F). This quick freezing process ensures the formation of small ice crystals, which helps to preserve the cellular structure of the fruit.
- Freeze-Drying (Lyophilization): The frozen strawberry slices are placed in a freeze-drying chamber, where a vacuum is created. Under this vacuum, the ice crystals sublimate, meaning they transition directly from a solid state to a gaseous state, bypassing the liquid phase. This process removes the water content from the strawberries while preserving their shape, color, and nutritional value.
- Sorting and Packaging: After freeze-drying, the strawberry granules are sorted to remove any irregular pieces or clumps. The finished product is then packaged in airtight containers or pouches to protect it from moisture and air, ensuring its long shelf life and maintaining its quality.

- Contains Dietary Fiber: Strawberries contain dietary fiber, which aids in digestion, promotes gut health, and helps regulate blood sugar levels [3].
- Convenient and Long-Lasting: The freeze-drying process extends the shelf life of strawberries, making them available year-round. The granules are easy to store and use, offering a convenient way to add strawberry flavor and nutrition to various foods.
- Versatile Ingredient: These granules can be used in a wide range of applications, from breakfast cereals and yogurts to desserts and baked goods. They add a burst of strawberry flavor and a pleasant crunch to any dish.

Botanical Source
The strawberries used to make these granules typically come from the Fragaria × ananassa species, which is the common garden strawberry. This species is a hybrid of two different wild strawberry species and is cultivated worldwide for its delicious fruit [4].
Packaging and Storage
To maintain the quality and freshness of freeze-dried sugared strawberry granules, the product should be packaged in airtight, moisture-proof containers or pouches. The packaging should also protect the granules from direct sunlight, as prolonged exposure to light can degrade their color and flavor. It is recommended to store the product in a cool, dry place, away from heat sources and humidity [5]. Once opened, the package should be resealed tightly to prevent moisture absorption, which can cause the granules to become sticky or lose their crunch. When stored properly, freeze-dried sugared strawberry granules can maintain their quality for an extended period.
