_____________is used commercially in the preparation of jellies, jams and marmalades because of its ability to form a thick gel-like solution.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Pectin.
Pectin is used commercially in the preparation of jellies, jams, and marmalades due to its natural ability to form a thick, gel-like solution when combined with sugar and acid. It is a type of soluble dietary fibre found in the cell walls of fruits, especially in apples and citrus peels. During cooking, pectin helps in thickening the mixture, giving the final product its desired texture and consistency. This gelling property makes pectin an essential ingredient in fruit preserves, enhancing both shelf life and quality of the products.
