No air contact? Seems to be puffery to me as it is in contact with air throughout…a reasonable person would understand this.
No oxidisation? Similar to the one above
Removes the air? It does some removal which may affect storage etc, and then it becomes the same as above
Max nutrition? Throwaway line, puffery
Prevents oxidisation of fruits and vegetables? Doesn’t say how much so I think it is puffery as even if it only prevents a small amount of oxidisation it meets the broad claim.
preserves vitamins and nutrients? No definition of amount so again I think it is puffery as even a small amount of preservation meets the criteria.
better taste? Subjective so puffery
stays fresh, smooth, full of nutrition…even overnight? again broad statement and only needs to remain fresh smooth (and what is “full of nutrition” meaning) overnight, when did the overnight storage commence and in what conditions…puffery
nutrition maximised? No definition attached to what they mean by maximised…it could easily be “for the conditions it was stored under” or “for the length of time we measured it for”…puffery.
The only one where they could more easily fail is the " 40% extra vitamin C" but for what fruit, vegetable or mix and for how long before this was measured. If oxidising is retarded for some period of time this extra 40% could be the case compared to a juice that is exposed normally to air for the same measured time.
As I said above I don’t like it but they seem to have ticked the boxes to avoid penalty, this is only my opinion of course. The only way this is going to really pass or fail is if the claims are subjected to scrutiny by the Authority vested with the power to call this out and the Authority in this case is the ACCC.
There of course is the case for further tightening of puffery definition and laws. This could help stop this stuff even appearing. Puffery should be a thing long gone, if a claim is subjective then they need to make clear it is and under what conditions. If they make a statement of benefits they need to show (or link to) the evidence that proves the claims. But the law allows this abuse of language and claims and that’s what needs to change.
