Translation of a Polish Food name

[ALLIGATOR]

Hi There I have a Jar of Polish Preservative and of course it is written all in Polish. It reads as Follows. NISKOSTODZONY. Could somebody Translate that into Engish and Oblige. I thank you in advance. ALLIGATOR

[dzug]

the NISKO bit means low (as in low fat, low calorie, etc) but I can't find anything resembling the second half.

Have you got the spelling right - are there any funny marks on any of the letters?

[dzug]

Got it

That T is not a t, it's an ł - like an with a line through it. Means low sweetening presumably low sugar when used of jam

[ALLIGATOR]

Hi DZUG, Thank You for the Information, I was under the Impression that it would be the name of the fruit but it looks like I was Wrong, In addition to that name there is some more writing and I would be interested to know what it means,If you can help and you can spare the time I would be most Grateful.
Thank You. regards, ALLIGATOR.
