What's the secret to creating nutritious and longer-lasting smoothies and blended drinks? The answer is vacuum blending. Compared to traditional blending, vacuum blending preserves 40% more vitamin C* and keeps fruit and vegetable smoothies or drinks fresh for up to 24 hours. Using this nutrient-preserving technology, the Oster Blender with FoodSaver Vacuum Sealing System removes oxygen from the jar before blending, resulting in less oxidization of ingredients, for better blending results you can see. By getting rid of oxygen, vacuum blending also allows you to create a smoother, more colorful blend that’s free of bubbles, foam, and has a better consistency*. It also features a powerful 1000-watt motor that powers through ice, frozen fruits, and vegetables, for smooth and creamy results. This blender also includes a blender-compatible 24-oz. storage cup that keeps your blended drinks and meals fresh for up to 24 hours and easy to take on the go.
