PopcornHistory

  • Oldest popcorn discovered in New Mexico, USA (5,600 years old)
  • Native Americans grew hundreds of varieties, invented “poppers”, and wore popcorn as a decoration
  • Popcorn was served at the 1st Thanksgiving!
popcorn history
PopcornHistory
  • Colonial settlers used as “puffed” cereal for breakfast
  • Popular during the depression and WWII due to its low cost
important elements of popcorn
Important elements of popcorn
  • The hard shell (pericarp)
  • Moisture
    • inside pericarp
  • Starch
    • inside pericarp
how popcorn works
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
Types of Popcorn
  • There are two main types of Popcorn Kernels
  • Butterfly kernels - large, light, and fluffy
  • Mushroom kernels - used for coating
growing popcorn
Growing popcorn
  • Popcorn is planted between April 20th and May 10thusually
  • A soil temperature of 10-13°C (50-55°F) is necessary
harvesting popcorn
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

storing 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
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
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
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
Processing popcorn-step 3
  • Optical Sorting separates kernels by color
  • Optical Sorter inspects all kernels
packaging bulk and microwave popcorn
packaging Bulk and Microwave Popcorn
  • Must be packaged so that popcorn remains at the optimum moisture level
  • Plastic is commonly used
flavored popcorn
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 popcorn1
Flavored Popcorn
  • Which flavored popcorn is most people’s favorite?
  • Caramel!
