People can now easily make popcorn at home or purchase it from local stores. There are grocery stores that sell sugar-free, reduced-calorie caramel corn, plain salted unbuttered instant popcorn, and many other varieties. Corn kernels are also available and can be popped on the stove at home. People can also choose from many different colors and types of popcorn, and popcorn oils from grocery shops. However, all varieties of colored popcorn have a shade of white, but each color does have its own exclusive appearance, texture, and, most importantly, flavor.
A popcorn machine contains a heating device that pops the corn. Each popcorn kernel contains a little amount of water inside a circle of starch, which is encircled by the hard outer surface of the kernel. Upon heating, this water usually expands, and, with corresponding pressure building against the starch, it then pushes through the hard surface, making the corn burst open. With this, the soft starch inside the kernel inflates and bursts turning the core inside out.
The best way to store popcorns is in airtight containers. It needs to be stored in cool places such as cupboards or the pantry. If popcorn is stored in a refrigerator it is likely to get dried. If this happens, people can always refresh the dried popcorns, by placing the kernels in a jar and fill it with water to the brim. This would take around three days or more but the water helps to moisturize the kernels, which will help the kernels to pop.
There are many machines available for popping corn. Popcorn machines can be of various types and sizes. There is a large selection of popcorn machines for home use as well. They are comparatively smaller and simple to use. There are some popcorn machines that come with carts and are especially designed for mobile or stationery vendors to be used in shopping malls. It is wise to look for corn popping machines, which have some scientific lab testing before making a choice. Certified popcorn machines tend to pop 99% of the corn and produce the maximum volume of popcorn with minimal waste.
