Answer: These methods works by denaturing the enzymes. The first and the second method is to change the temperature and the third method is to change the pH.
Explanation:
The browning of the fruits or vegetables takes place due to the action of the enzymes. The enzymes inside the body of the organism works under specific conditions.
These conditions are temperature and pH. Change the optimum pH and temperature of the environment of enzymes could denature it.
In these case the enzymes would not work efficiently and the browning of fruits will not take place.
By cooling or boiling the fruit changes the temperature of the enzyme and in this temperature the enzymes do not work effectively.
In case of ascorbic acid the pH is acidic and enzymes do not work at lower pH.
So, by changing the pH and temperature, the enzymes do not work.
Radon is a radioactive noble gas. It is really difficult to find it naturally since it does occur, but in really small quatities as it is a radioactive element, and therefore dacys.
Symbol: Rn
Atomic number: 86
