Is Ripening of fruits a reversible change?

Explanation: ripening of fruit is a chemical change. during during ripening the pigment present in the skin of the fruits changes and this cannot be reversed back. this this a chemical change as it cannot be turned into in the raw after converting it into a ripe fruit.

Why fruit ripening is an irreversible process?

After proper maturity, fruits ripen in nature by using many physical and biochemical events. This process is irreversible and leads towards what is called senescence. The fruits become soft, change in colour, and develop characteristic aroma and flavour, with an increase in sugar level and reduction in acid content.

Is ripening of fruit a physical change or chemical change?

A change in which chemical composition and chemical properties of the reacting substances undergo a change is called a chemical change. During ripening of fruits or growing of plant into a tree, a chemical change occurs which helps in ripening and growing of plants into tree and cannot be reversed.

Is mango ripening reversible?
