Canning berries without lemon juice / citric acid???

[pookahjade]

So I would like to be able to can blueberries and the like but every recipe i have found calls for lemon juice or citric acid. I understand the point of acidifying canned foods but my dh is allergic to citric acid. Anyone know of any other way to lower the pH enough to can berries? I don't think vinegar would taste very good,  Lol.

Is he allergic to citrus or citric acid? 

Honestly, vinegar would probably be the next easiest.  I'd probably use apple cider so it's less of a harsh flavor, but a Tbs in a few cups of berries + sugar isn't really going to be noticeable.  Barring that, maybe ascorbic acid? 

Although with blueberries, I'd probably just freeze them - it's far easier.

It's really tricky to substitute the acid when canning. I'd second just freezing them. I always freeze blueberries since it's much simpler - just spread them on a rimmed baking sheet and put them in the freezer for an hour or two until just frozen, then transfer to freezer bags and return to the freezer.
