I have never heard of this brand so I had to search this up,
Marinari’s mango I found had sugar as a second ingredient, so added sugar, which I say avoid it. Added fats and sugars are not good.
Their website says they have organic versions and no added sugar, I checked the ingredients for those and they seem fine from their ingredients, but when I feed fruit to my sugar gliders, I basically only make sure it contains the fruit itself only that.
