Popcorn History Important elements of popcorn - The hard shell (pericarp)
- Moisture
- Starch
How popcorn “works” - When popcorn is heated, the moisture inside causes the pericarp to burst
- The starch expands into “bubbles” which fuse together, creating the white, fluffy substance
- This process will only occur if the correct amount of moisture is present
Types of Popcorn - There are two main types of Popcorn Kernels
- Butterfly kernels - large, light, and fluffy
- Mushroom kernels - used for coating
-
Growing popcorn - Popcorn is planted between April 20th and May 10th usually
- A soil temperature of 10-13°C (50-55°F) is necessary
Harvesting Popcorn - Popcorn is harvested when the kernel has moisture content of 16%-20%.
- Popcorn that is too dry may not pop well
- Popcorn that is too moist may spoil when stored
Summary - Bulk or Microwave popcorn
Storing Popcorn - Storing is also know as “conditioning”
- Once picked, the corn must be dried until it reaches its optimum moisture level of 13.5% to 14%
Cleaning popcorn - Foreign material, broken kernels, corncobs, and dirt must be removed
- Cleaning process consists mainly of three parts:
- separating by size
- Separating by lower/higher densities
- optical sorting
Processing popcorn-step 1 - Separating by Size uses a screen cleaner
- Has 2 screens (1 large holes and 1 small holes)
Processing popcorn-step 2 - Separating by lower/higher densities uses a shaking gravity table
- Removes less dense cracked kernels & more dense dirt and stones
Processing popcorn-step 3 packaging Bulk and Microwave Popcorn - Must be packaged so that popcorn remains at the optimum moisture level
- Plastic is commonly used
Flavored Popcorn - After cleaning, popcorn is popped, and while hot flavors are added in a large tumbling devise to coat the popcorn
- The coated popcorn is cooled
- The popcorn is then packaged and shipped
Flavored Popcorn - Which flavored popcorn is most people’s favorite?
- Caramel!
