Is store-bought juice as healthy as home-made juice?

If you buy juice in a store it has almost certainly been pasteurized or HPP’d.  The FDA states that all juice that is to be distributed must be pasteurized or HPP’d, it’s the law.

 Now pasteurization has been around for years.  In case you didn’t know, the juice is heated to a very high temperature short a vey short time, then cooled rapidly.  This effectively kills any bacteria in the juice, but at the same time wipes out most of the nutritious benefits of the juice too.

Understandably this has never been a popular for real juice enthusiasts, so things seemed to be getting better a few years ago when HPP (High Pressure Processing) came along.  HPP works by putting bottles of untreated juice into a high-pressure chamber full of cold water, then increasing the pressure massively, equivalent to the bottom of the ocean, which enables to juice to be stored for somewhere up to 45 days.  There is no conclusive evidence to show to what extent HPP damages the enzymes and nutrients in juice, but some numbers thrown around suggest that HPP kills up to 20% of nutrients and up to 80% of enzymes.  However it should be noted that these figures are from tests done immediately after the juice has been HPP’d.  The reading surely won’t be as good after the juice has been sat on the shelf for 45 days. 

So what about untreated juice?  Well if you go to a juice bar and the sell-by date on the bottle isn’t more than a few adys away, you can be quite sure it hasn’t been treated and will therefore contain all the nutrients and enzymes that nature intended.  Same goes for home-made juice.  If you use a good quality slow juicer the juice you make at home will really be the best you can get.  Drank straight away, untreated juice has the very best health benefits you can get from juice.

 

Should I buy a single or twin gear juicer?

Assuming you have already figured out that slow juicers make better juice than centrifugal juicers, you may now be wondering if twin gear juicers are really worth the money?  After all there is a range of perfectly good single gear juicers available for under $400, and with twin gear juicers ranging anywhere from $450 to $1,650, the price difference is pretty huge.

 So why are they so expensive?  Well they key difference between a single gear and twin gear juicer is the system for crushing the produce.  With a single gear juicer the produce is crushed by a single auger against a seize, with the juice being squeezed out.  This system works perfectly well, so how can a twin gear juicer be better?  Well with a twin gear juicer the produce is crushed and squeezed between two long metals gears that fit together so tightly, that you would think there is only space for a piece of paper to fit through.  As the produce passes along and through these metal gears, it is crushed paper-thin and given the hardness of the crushing surface, more juice tends to be extracted versus a single gear juicer.

 So there’s reason #1, more juice!  With 1lb of organic kale costing around $2.50, if you are juicing every day over a year, and you get 15% more juice with a twin gear juicer, that’s a saving of almost $137 per year.

That’s not all, with a twin gear juicer the metal gears tend to break down the cell structures of the fruit and vegetables more completely than a single auger juicer.  With the vitamins and nutrients often packed tightly into the cell structure of fruits and vegetables, your juice will be more nutritious the more the produce is broken down.  And there is reason #2 – more nutritious juice!
