Stove top pasteurizing cider without added pectic enzyme
 
Hi all,
i'm approaching the final stage of production of my first semi-dry cider: the pasteurization!
The problem is, near where I live there is no pectic enzyme. Brewing shops are specialized on winemaking and do not keep this product.

Is there a way to pasteurize without get the pectin fall out of suspension?
Maybe some combination of temps/bath-holding time?

And also, if pectin falls to the bottom, the taste is modified hugely or it's still good?

Thanks!

the worst thing that can happen is that the cider stays a bit cloudy. this may or may not happen; just go for it and don't worry!

Thank you for the reply.
It's already a bit cloudy.
Just asking because, from what i read pasteurizing w/o the enzyme, seems a delicate step.

I've read here a problem of "gelification" in this process http://www.homebrewtalk.com/f32/pasturizing-cider-seperation-problem-362215/ ,

and also here speaks about the denaturation of pectin @ 175F

I just heat pasteurized some cider without enzymes and residual fell to the bottom -and looked rather unappetizing. I also cold crashed some, it kept the cloudy look but no residual fell to the bottom.

Based on my experience, I wouldn't recommend heat pasteurizing an unclear cider.

Unfortunately, I got my batch already bottled.
There are other viabile alternatives for stopping the bottle fermentation (a part from re-bottling)?

Cold crash. This worked fine on a few bottles for me.

Isn't cool crash a tecnique regarding yeasts and applicable prior to bottling with multiple racking? http://www.homebrewtalk.com/f32/cold-crashing-cider-46017/

However, I found this scientific article that explores the heat resistance in S.Cerevisiae of Pilsner beer. The physical and chemical characteristics should be roughly the same, so, applying this to the cider it turns out that 2.5mins @ 50C give a 3log reduction of viable cells.
Isn't so much, but... I planning to try a security window of temps/times between yeast killing and pectin denaturation.

Hey Ronkas, did you figure this out? I don't want to lose my pectin but I also don't want gunk.

Mail order some pectic enzyme?
