What it is and where it comes from
Pectin is a natural fibre from fruit, mostly taken from apple leftovers and citrus peel. It makes jam set.
Where you find it
Jam, marmalade, fruit sweets, jelly, yoghurt and fruit drinks.
What to look for on the label
Nothing to check for halal. Fruit gums made with pectin instead of gelatin are a good choice.
This is a guide, not a fatwa. Recipes change, so check the label, look for halal certification, and ask your local imam where scholars differ.
