It's a chemical change.
It is due to a defense mechanism in the fruit, which is activated when the fruit is cut from the tree.
There are three main factors involved in the ripening and browning process, they are: enzymes, oxygen and phenols. Enzymes are protein-like substances that speed up or initiate chemical reactions. Phenols are defensive mechanisms the plant uses to fend off insects and microbes. The specific enzyme is called polyphenoloxidase. When the banana is attacked, the phenols are activated in the presence of oxygen by this enzyme. In this process the brown color is produced as a side effect. The first time the banana is attacked is when it is cut from the tree. Exposure to cold air, certain gases, and physical damage of the fruit will hasten the process.

Is mashing banana physical or chemical?
Mashing a banana is a physical change because it does not alter the chemical composition of the banana. The act of mashing simply changes the physical appearance and texture of the banana without creating any new substances.
How ripening of bread pieces a physical change?
Ripening of bread is a physical change because it does not involve any change in the chemical composition of the bread slices. The process involves the redistribution of moisture and air within the bread, causing it to become softer and more palatable without altering its chemical structure.

Is ripening fruit a physical or chemical change?
Ripening fruit is a chemical change because it involves the breakdown of complex molecules in the fruit resulting in changes in color, texture, and flavor. This process is driven by enzymes and chemical reactions within the fruit.
Is mashing a banana a chemical change or physical change?
This is a physical change, because you are only changing the physical appearance, not the substance's chemical properties.
