Apricot stringy seeds

GarionEvans says...
The most common problems that I have found with these type of things are:
- the mixture you put them in when they are in the bottle will slightly denature it, all preservative will do this
- the denaturing of the fruit caused by the syrup/ jam contents and constituents will occur because fruits, especially stone fruits, will have some sort of chemical reaction. Not all preserves will come out the way they went in

Hope this helps:)
