Inside a corn kernel, there is a small amount of water enclosed by a hard outer shell. When the kernel is heated, the water inside turns into steam, creating pressure within the kernel. At a certain temperature, the high pressure causes the shell to crack, or in other words, the kernel begins to pop, and the starch inside expands. This process results in soft, fluffy popcorn.<\/span><\/i><\/p>

– Moisture content inside the kernel: If the kernel is too dry, there won\u2019t be enough steam to create pressure.<\/span><\/i><\/p>

– The shell must be intact: If the shell is cracked, the steam will escape.<\/span><\/i><\/p>

– Sufficiently high temperature: If the required temperature (around 180\u00b0C) is not reached, the kernel won\u2019t have enough pressure to pop.<\/span><\/i><\/p>
