Choice Magazine – Australia’s Leading Consumer Authority

Australia’s leading consumer authority has the living proof about living juice!

In October 2007, Choice tested the claim that non-centrifugal juicers produce juice that lasts longer and contains more nutrients.

They found that the manufacturers’ claims are true… and Vitality 4 Life has the best juicers!
Choice confirms, the test shows that the juice from the Hippocrates juicer contains more nutrients; in fact well over double the beta-carotene and alpha-carotene of the juice from every other juicer in the test and it lasts longer.

Manufacturers claim cold-press-style machines’ juice is more nutritious and that it’ll stay fresh and tasty for up to 48 hours. According to the makers, the gentle, slow-turning action of a cold press machine produces a greater quantity of juice, which retains more vitamins, minerals, enzymes, phytochemicals and fibre than that produced by other methods. Their argument is that high-speed centrifugal juicers heat up the juice, allow air to enter and therefore cause damage to some of the perishable nutrients.

Health Claims Tested

	Centrifugal Juicers	Non-centrifugal Juicers
Less oxidation			The apple juice from the centrifugal juicers separated and went brown a few minutes after juicing
More fibre			The Greenpower Hippocrates & the Oscar Vital Max scored the highest at 90% on performance
More nutritious			The Greenpower Hippocrates’ juice contained well over double the beta-carotene and alpha-carotene of the juice from every other juicer in the test
Greater quantity of juice			Although the cold pressed juicers did produce more juice, the Healthstart Compact scored the lowest for the juice produced because its carrot juice was a little grainy and it produced a lower quantity
Easier cleaning			All the centrifugal juicers have large, bulky parts that are hard to fit into a domestic sink for cleaning
Stays fresh for 48 hours			The juice from the non-centrifugal juicers didn’t separate, smelt fresh and looked palatable and green after 48 hours in the fridge

Choice scored the juicers for performance & ease of use. Choice also tested the manufacturers’ claims that juice made by cold-press-style machines is more nutritious and that it’ll stay fresh and tasty for up to 48 hours.

Key findings:

• All the juicers performed reasonably well, with even the worst getting a good score
• non-centrifugal juicers do extract more nutrients — in some cases double or even three times as much!
• Juice from the non-centrifugal juicers still looked and smelt palatable after 48 hours.
• All the centrifugal juicers have large, bulky parts that are hard to fit into a domestic sink for cleaning.

Nutritional analysis

Choice tested the nutritional claims, by sending a sample of carrot juice from each juicer to a lab to be analysed for minerals (potassium and calcium), Vitamin C and the phytochemicals alpha and beta-carotene, to see if the non-centrifugal juicers did extract or retain more nutrients.

The juice from all the non-centrifugal juicers contained about double — in some cases triple — the calcium of the juices produced by the centrifugal juicers (bar one, the Magimix).

The Greenpower Hippocrates’ juice contained well over double the beta-carotene and alpha-carotene of the juice from every other juicer in the test.

Potassium was much the same for all juices tested.

Vitamin C quantities were too low to measure accurately.

How long did the juice stay fresh?

A sample of apple juice from each juicer was refrigerated for 48 hours, then evaluated for colour, overall appearance, smell and texture, to test the claim that juice from non-centrifugal juicers holds up longer.

The apple juice from the centrifugal juicers separated and went brown a few minutes after juicing. After two days it was noticeably deteriorating, didn’t smell fresh, had a hard froth on top (except juice from the Magmix) and a layer of sediment at the bottom — indicating a higher level of oxidation.

By contrast, the juice from the non-centrifugal juicers didn’t separate, smelt fresh and looked palatable and green after 48 hours in the fridge, indicating less oxidation.

And the reason why? It’s possible that the oxidation or friction from higher-speed centrifugal juicers turns the juice bad faster than the slow-turning machines.

Test results

Here’s some test results of the juicers tested by Choice, grouping centrifugal & non-centrifugal juicers. The overall score is made up of 50% performance & 50% ease of use.

Performance: The tester processed a kilogram each of carrots, apples, oranges and a combination of watermelon and pineapple. From these, she evaluated each juicer’s abilities across a range of textures and consistencies. She was looking for juice that was smooth rather than pulpy, grainy or frothy.

Ease of use: Included how easy it was to ‘feed’ the juicer (affected by the size of the chute and how small the contents had to be chopped before it would fit), assembly and disassembly of parts, cleaning, use of controls, collecting juice, and removing pulp.

Safety: Each juicer was also assessed to see how easy it was for hands of various sizes to come into contact with the blades through the food chute, when it was fully assembled. Safety wasn’t scored, but you’ll find comments in the profiles.

The Healthstart Compact and the Champion produced juice containing  high levels of calcium. Apple juice from both looked and smelt palatable after 48 hours. The Healthstart Compact juicer scored the lowest for the juice produced because its carrot juice was a little grainy and it produced a lower quantity.

Benefits of cold press juicers

There are several advantages to cold press juicers…

• If you store your juice rather than drinking it soon after making it, one of these machines may suit you
• You can also use some of them for food processing, mincing, grinding coffee beans and for making sausages, pasta/noodles, seasonings, nut butter, soy milk, baby food and ice cream
• They have fewer parts and are easier to clean
• The Cold-press juicers can juice wheatgrass and herbs
• Their warranties are generally longer than those for centrifugal juicers
• They’re much quieter than centrifugal models

Choice confirms the test shows that the juice from the Hippocrates juicer contains more nutrients than centrifugal and other cold press models, and it lasts longer.

Conclusion

Non-centrifugal models do produce juice that lasts longer and contains more nutrients.
