What is Freeze Drying
So, how is it we able to carry Blendis in our bags and avoid the hassle of worrying about the freshness of fruit and veg? Blendi’s unique advantage is borne out of a process known as Freeze Drying. But what is Freeze Drying? Fruit and veg are absolutely loaded with the luscious liquid H20, in fact some of them are up to 80% water! This is what gives them their shape texture and general juiciness. Unfortunately, it’s also what allows them to ripen, and subsequently spoil, with the introduction of mould. We’ve all had the best intentions of buying a load of fruit and veg for smoothies only to find yourself with remnants rotting lingering in your larder when you don’t get through it quick enough! This is where the freeze-drying process comes in. The modern day freeze drying process is one where perishable food is dehydrated leaving the item of food frozen, dry and with all its nutrients locked inside ready to pop back out on the addition of water. All of this freeze-drying process happens in a laboratory however its origins have a much more natural feel. The freeze drying process we use today hails from one used in the 15th century when the Incas used to leave their food out overnight in the freezing Andean night time to freeze it and make it more transportable.
Simply Pressing the Pause Button on Nature Until you are ready to Press
*Research conducted by Sheffield Universtiy in 2013 measured the nutrients in freeze dried , chilled and fresh Strawberries, found that refrigerated fruit retained only 20% of their antioxidants. While freeze drying no significant impact on their nutrient content, the freeze dried strawberries retained all their vitamin C and polyphenols and 92% of their antioxidants.

Blendi’s Freeze-Drying Process
Think it sounds too simple to be true? Here’s the scientific freeze-drying process step-by-step to give you the specifics!
- Firstly, fresh fruit and veg are picked at a low temperature when they are at optimum ripeness.
- The water content is then turned to ice.
- The air pressure around the piece of food is then lowered which turns the solid ice into vapour.
- This process is called sublimation.
- Sublimation trumps any other drying process because it dries the fruit and veg without heating it which preserves the nutrients, taste and colour like the day it was picked! Leaving you with sublime fruit and veg by way of sublimation!
Scientific sorcery it may seem but at the smoothie end, it’s as simple as Open, Add and Enjoy!
Open (your Blendi fruit and veg) Add (water in your Blendi blender) and Enjoy (your delicious Blendi Smoothie)!
Handpicked Fruit & Vegetables
Ok how long do you have? The freeze-drying process gives the edge over frozen or dried food like a jet-powered engine in a bicycle race! The powerful nutrients found in fruit and veg are delicate flowers that hate the heat so when they’re exposed to a thermal drying process they run for the hills leaving you with vacant fruit and veg that’s had a nutrient exodus. Thankfully this is not the case with freeze drying! Here’s just a few of the benefits of the freeze-drying process.
- Heat sensitive vitamins like pro-vitamin A (beta carotene) and vitamin C (ascorbic acid) are preserved at near pre-frozen levels meaning when you have a Blendi smoothie, you get all of those vitamins uncompromised be heat.
- The freeze-drying process also maintains the pre-frozen levels of fiber, which ticks your gut-health box and helps prevent against metabolic disease like heart disease and diabetes.
- Fruit and veg also contain anthocyanins, flavonoids and polyphenols, which will all stay right where they belong during the freeze-drying process, these are what give fruit and veg their characteristics and health benefits.
- Take for example Blendi’s ‘Purple Rain’. It is packed with tasty blueberries which have anthocyanins: β-sitosterol, stigmasterol, and kaempferol, fthey might be a tongue twister, but they also protect against the development of tumours and also give blueberries their beautiful vibrant colour.
All You Need To Do
Blend & Enjoy!
Are freeze-dried fruits and vegetables good for you?
Yes! This is the same as asking are fresh fruit and vegetables good for you. The freeze-drying process removes none of the anti-oxidants and fiber and only a miniscule amount of certain vitamins, meaning freeze-dried fruit and vegetable are just as good for you as freshly picked ones.
Are there any chemicals used in the freeze-drying process?
No. There is nothing added to fruit and vegetables during the freeze-drying process. It’s simply put, a lowering of the temperature and subtraction of water. So you can enjoy you Blendi safe in the knowledge that you’re not consuming any chemical nastiness at the same time. Just fruit and veg as nutritious as the day it was picked!
What is the difference between freeze-drying and drying?
Moisture content and nutritional values are the two main differences. The freeze-drying process removes 98-99% of the moisture from fruit and vegetables, a process carried out while the items are frozen, thus keeping in them in their raw state and preserving all but a miniscule amount of the nutrients.
The drying process allows air to evaporate the water (only up to about 90%) from the produce thus somewhat wilting them and losing some of the nutrients.
What is the difference between freeze-drying and dehydration?
The dehydration process is a laboratory drying process that further removes the moisture content of foods (up to a bout 95%). But as with air drying, the food loses nutrients from the thermal damage during the dehydration. Dehydration tends to result in the loss of Vitamins A and C, thiamine, riboflavin and niacin. The freeze-drying process will preserve all but a miniscule amount vitamins, making it a more nutritionally sound choice for preserving your fruit and veg.
