Question

explain the following browing cut apple can be prolonged by applying lemon juice? and how the vanspati ghee made?​

Answer 1

Answer:

Explanation:

Apple turns brown when they react with oxygen in air... Lemon juice creates a barrier between apple and oxygen......the oxygen in air reacts with lemon juice until it gets evaporated.. Hence browing is prevented for sometime

Vansaspathi ghee or dalda.. Is made by hydrogenation process which means adding hydrogen...

Here hydrogen is added to vegetable oil(a saturated compound) to vanaspathi ghee(an unsaturated compound) in presence of nickel catalyst......
