How do you measure the moisture content of popcorn?
How do you measure the moisture content of popcorn?
Shell a portion of the ear and pop the kernels. If the kernels contain too much moisture, the popped corn will be small, rough, and “chewy.” Allow the popcorn to dry for another week. Then shell and test pop a few additional kernels. When the kernels pop well, shell the remainder of the popcorn.
Do all brands of popcorn contain the same percentage of water?
What is the equation for finding the mass of the 20 popped kernels of popcorn? Do all brands of popcorn contain the same percentage of water? No, all of the brands of popcorn contain different amounts of water (see data) What are some likely areas of error in this experiment?
What moisture should popcorn be?
between 13 and 14%
The ideal moisture content for popcorn is between 13 and 14%. Once or twice a week, shell a few kernels and try popping them.
How does popcorn pop lab?
Popcorn pericarp is much stronger than that of all other corn kernels and is able to retain this pressurized steam up to 9.2 atm (135 psi). Above that pressure, the pericarp ruptures, releasing the steam and gelatinous starch that solidifies upon cooling. The resulting popped kernel is 40 to 50 times its original size.
How do you dry shelled popcorn?
Shell a few ears and lay the kernels on a dehydrator tray. Dehydrate between 120-130°F, checking few hours until it’s popping well. To save space, shell your popcorn and place it in airtight containers. It will keep for several years.
What is the percent by mass of popcorn in popcorn kernels *?
People often wonder what is the ideal percentage of water in popcorn kernels for best popping. Popcorn is harvested in the fall when the kernels’ moisture content is between 16 and 20%. The kernels are then stored in bins where they are dried by forced air until reaching an optimum moisture level of 14%.
Is popcorn a hydrate?
Hydrated kernels: At least 8 hours before (or the night before) you pop all your kernel samples, make your hydrated sample of popcorn kernels (“hydrate” means “to add water”).
Does popcorn need oxygen absorbers?
Popcorn kernels are great for long term food storage because they keep for a very long time, plus they are cheap to buy. I would suggest storing your popcorn kernels in a air tight can or bucket with oxygen absorbers if possible for longest storing freshness.
When popcorn pops its volume increases by what percent?
References (26) Nevertheless, the most important factor influencing popping volume is the moisture content at the moment of popping. Researchers agree that the maximum of popping volume is produced at grain moisture ranging from 11.0% -15.5% (Allerd-Coyle et al., 2000; Shimoni et al., 2002; Pajić et al., 2006).
What’s the perfect time for popcorn?
STAY AND LISTEN. POPPING TIMES VARY FROM 2 TO 4 MINUTES (1 to 2 minutes for Mini Bags). For best results, stop microwave when popping slows to 2 to 3 seconds between pops. Overcooking may cause scorching.
