What temp do apples freeze at??

Hi. I am wondering if anyone on this forum can tell me at what temperature apples still on the tree will freeze at. We are going through a real cold snap and I am trying to decide if I must pick the apples on our late tree. They aren't quite ripe yet. It seems to me that I read somewhere that apples can take temps down to 21 F for a short period of time but I can't seem to find any information about this on the internet. It looks like the low for tonight is forecast for 25-27 F which I believe they will be fine at but tomorrow night's forecast shows a low of 22 F which is what I am concerned about.

I know there is a similar thread a couple of threads down, but I guess I am looking for an actual temperature if someone on this forum happens to have that knowledge or a link to information about this. Thanks for any information anyone can give me.

One thing not in the linked discussion is that apples are divided into three types scientifically, and have different damage properties.

Type I correspond to Summer apples, and these will damage easily, maybe taking 28F for a short time. They also have the property that if the apple is damaged anywhere, the entire apple will usually rot.

Type II corresponds to Winter apples, and these are very robust, taking down to 20F without damage. They also have the property that if any part of the apple is damaged, it will heal itself, even if off the tree. In the native apple forests, there are many apple trees that will go bare and hold on to fruit for quite a while longer without the fruit having any damage.

Type III corresponds to all the hybrids in between the two, these behave specific to the variety.

I forget the reference, I can dig it up if anyone cares.
