Share 'shelf life'

 Hi everybody how much i appreciate all these discussion on the forum it is just awsome to see that there are simple solution sometines. My question today is about shelf life of ganache filled pralines;Do i have to add sucre inverti (sorry i am french and i don't know how to say it in english and to look for it now will just take me out of focus!) and glucose ? At what stage do i have to add them…
