      These Kitchen Appliances Really Suck - And That’s Why You Want One!

      It’s not often we get excited about something that sucks but we are really excited about these new additions to our range, and they definitely do really suck. They suck like a big sucky thing that just won gold in the Olympic sucking competition. And that’s great! Before you click away thinking we’ve lost our minds, our subject here is the latest development in kitchen appliances and it’s aimed squarely at the health enthusiast - it’s called a Vacuum Blender

      Vacuum blenders have been developed to address a particular concern of people who are looking to maximise nutrition and get the best from their healthy blender recipes - that concern is how to preserve the nutrition and flavour in blended ingredients and slow down the damage caused by oxidation. Just as masticating juicers help us to make fruit and vegetable juices with a better shelf life and reduced nutritional spoilage, by incorporating less air, the vacuum blender tackles this tricky issue in the more problematic arena of high speed blending. Read on to find out why a vacuum blender can help improve the nutritional outcomes for you and your loved ones, whenever you use it.

      Oxygen: The Good News And The Bad News

      Oxygen is necessary for all animal life, it sustains us and enables many metabolic reactions in our bodies. But it does that for the microbes that can spoil our food too, and it is also the key reactant in oxidative processes that degrade vital nutrients and flavours. We can’t avoid the irreversibility of natural processes and over time everything decays. We can’t avoid the second law of thermodynamics and the arrow of time. But now we can at least push back by applying a little food science at home, using understanding to improve our health. With a vacuum blender you can simply remove the problems caused by oxygen, by removing all the air from the blender jug before you blend.

      Standard Household Blenders Speed Up Food Degradation

      A characteristic of a normal household blender is that the high speed blades immediately whisk lots of air into whatever ingredients you are blending. To make things worse, the process of blending smashes the ingredients into tiny particles, giving the biggest possible surface area of contact between your food and the villain of the piece: oxygen. Millions of tiny bubbles of oxygen mixed with millions of tiny particles of food. Practically every molecule of the ingredients in a traditional blender is swimming in an oxygen rich bath, and your blended food immediately starts to lose its nutritional value and flavours as a result. 

      Oxygen is necessary for microbes to become active and multiply, and to start digesting your food before you do! This can be quite beneficial, in yoghurts or fermented pickles for example. And it can be quite bad with things like pathogenic bacteria, mould, etc. Feeding the microbes with all the oxygen they need increases the risk that food deterioration will happen faster. By incorporating plenty of oxygen to feed the wee beasties that can cause our food to start to go off, a traditional blender exacerbates this kind of harm to our blended recipes if they are not intended for immediate consumption.

      Oxidation is a primary ​obstacle that many methods of food preservation try to address. From bags of salad to meats and fruits, food from the supermarket is often packaged in an inert gas like nitrogen to exclude the oxygen and prevent spoilage ​from oxidation as well as ​from microbial decay. Modified Atmosphere Packaging (MAP) using inert gas has become one of the most widely used methods of increasing the shelf life of shop bought foods. Canning foods also excludes air ​during the canning process. Vacuum packaging is used to exclude the air from around foods like nuts as another preservation method. Yet another technique is the use of ‘oxygen scavengers’ which are reactive compounds incorporated into packaging components that ‘scavenge’ the oxygen from the air immediately surrounding the food.

      Oxidation has a lot to answer for when it comes to ruining our enjoyment of the full benefits of fresh, healthy foods. Fats become rancid, which means they not only taste off but they also contain toxic byproducts from the oxidation reaction. Raw food enthusiasts know this to be a problem when making healthy nut butters in a traditional blender for example - the nut butter tastes great to start with but the healthy fats soon start to deteriorate. Vitamin C is rapidly lost to oxidation, and it can never be a good thing to lose this vital immune booster and cell protector. Oxidation is responsible for the stale flavour in bakery products that have been exposed to air for too long, and the flavour in many foods deteriorates due to the oxidation of their aromatic oils. 

      Using a traditional blender, we assist all these progressive deteriorations by maximising the incorporation of oxygen into the food. This is partly why we always recommend that a fresh smoothie is best drunk immediately. But now some clever people have developed a great solution to this problem - The Vacuum Blender

      What Is A Vacuum Blender?

      A Vacuum Blender operates in the same way as a normal kitchen blender but it has a method of removing the air from the ingredients in the blender jug prior to blending them up. By effectively creating a vacuum in the jug, the thorny issue of introducing tiny bubbles of air into the ingredients is eliminated. Entry level vacuum blenders like the Tribest Dynapro have separate vacuum pumps that the user attaches to the top of the jug to pump out the air, either by hand or with a battery powered pump option. Vacuum BlenderMore advanced models like the Kuvings Vacuum Blender incorporate an electrically operated vacuum pump into the blender assembly itself, which sucks the air out of the top of the jug. The jugs have a seal in the lid that automatically maintains the vacuum until the user releases it to get at the blended ingredients. This means that the jug can also be used to store the finished recipe until use. Vacuum blenders like the Kuvings SV-500 also have additional vacuum storage tumblers that can be vacuum sealed separately using the blender pump, and then used to keep a range of blended recipes in the fridge for later use without significant loss of flavour or nutrition. 

      See And Taste The Difference

      The first thing you notice about recipes from a vacuum blender is their rich, vibrant palette of colours when compared to the aerated results you get without the vacuum. Blended drinks from a normal blender will split, separate and discolour relatively quickly because the air is already in intimate contact with the entire recipe as it is smashed to tiny pieces. This process happens much more slowly with vacuum blended recipes because the deterioration can only happen where the surface is in contact with air after blending and releasing the suction. If you also use a vacuum storage container for your recipes, the food will keep for up to a week (more for some recipes) in your fridge with very little loss of nutrients. It will still keep much longer than traditionally blended recipes in just about any sealed container that is filled enough to exclude air at the lid. 

      With side by side taste comparisons it is immediately noticeable that the results from a vacuum blender are better right out of the gate. Delicate compounds that give flavour to our food start to degrade as soon as the blades start to turn in a traditional blender, so it's easy to understand how not just our health improves with a vacuum blender, but our enjoyment of our favourite recipes increases too.

      A Big Plus For The Healthy Lifestyle

      There are no downsides to owning a vacuum blender for the health enthusiast. Sure, they’re not cheap, but they can be had for similar prices to high-end traditional blenders like Vitamix, which have so far enjoyed greatest prominence amongst nutrition aficionados (we wonder how long it will be before Vitamix have a vac blender?). 

      If you miss one vital point about vacuum blenders, you could be forgiven for thinking that they may be less convenient. After all, you have to wait an extra half minute or so before you can blend while the air is being removed from the jug don’t you? 

      In todays busy world many of us look for increasing convenience when preparing our foods. ​A cheap juicer ​that's difficult to clean might end up spending most of its life in the cupboard in some households. Similarly some of us ​may find ourselves less motivated to use a blender that takes a bit longer to use. Don’t worry. It may seem counterintuitive but a vacuum blender is actually more convenient than a traditional blender, if you want to make a priority of daily access to healthy blended recipes. The reason is the same one that was discussed above - oxygenation of blended ingredients.

      Nobody wants to consume separated, coagulated gloop that has lost much of its flavour and goodness and that is what you end up with if you try to store, for example, a smoothie from a normal blender for any length of time. This means that with smoothies they pretty much need to be made and drunk to order with a normal blender. (Let's just focus on the ubiquitous smoothie here, although this also applies to just about all your other recipes).

      With a normal blender seven smoothies a week is effectively the same as seven operations of getting the blender out, prepping ingredients, blending them, and cleaning up afterwards.
      Vac Containers In FridgeIf you are motivated and have plenty of time, no problem.

      But what if you could do one big blending session, perhaps on a Sunday evening ahead of a busy week, and then line up the finished smoothies in vacuum tumblers in the fridge door, confident that when you want them, they are as fresh as when they were made? Remember too that they were fresher when they were first made than anything from a normal blender. 

      When you are feeling a bit frazzled or rushed by a busy working life, it’s easy to let your healthy lifestyle choices slip. Maybe you don’t want to get the juicer out today? Maybe the blender can stay sat in the cupboard this morning because you're running a bit late and you’ll just pick up one of those inferior pre-made bottles at the station instead? Well, just as a good masticating juicer lets you make your juice in advance, a vacuum blender lets you prep all your healthy blended recipes in advance too, safe in the knowledge that they will continue to taste great and nourish you well for the rest of the week, or sometimes weeks ahead. In the end it seems, many of us may be more likely to stick with the programme and consume more healthy living foods if we get kitted out with a vacuum blender and use our time more efficiently by blending in bulk. At UK Juicers, we think only good can come from this exciting new invention!
