Popcorn gid5/5/2023 ![]() ![]() As the foam rapidly cools, the starch and protein polymers set into the familiar crispy puff. The hull ruptures, causing a sudden drop in pressure inside the kernel and a corresponding rapid expansion of the steam, which expands the starch and proteins of the endosperm into airy foam. The steam pressure increases until the breaking point of the hull is reached a pressure of approximately 135 psi (930 kPa) and a temperature of 356 ☏ (180 ☌). Under these conditions, the starch inside the kernel gelatinizes and softens. Īs the oil and water in the kernel are heated, they turn into steam. Unlike most other grains, the outer hull of the popcorn kernel is strong and impervious to moisture, and the starch inside consists almost entirely of a hard type. Įach kernel of popcorn contains moisture and oil. The Popcorn Institute (a trade association of popcorn processors) promoted popcorn consumption at home, bringing it back to previous levels. The rise of television in the 1940s brought lower popcorn consumption as theater attendance fell. The venture was a success, and popcorn soon spread. Ray Aden, Dickinson purchased popcorn farms and was able to keep ticket prices down. Popcorn was more profitable than theater tickets, and at the suggestion of his production consultant, R. installed popcorn machines in the lobbies of his Dickinson theaters. Their minds eventually changed, however, and in 1938 a Midwestern theater owner named Glen W. The snack was popular at theaters, much to the initial displeasure of many of the theater owners, who thought it distracted from the films. During World War II, sugar rations diminished candy production, and Americans compensated by eating three times as much popcorn as they had before. Thus, while other businesses failed, the popcorn business thrived and became a source of income for many struggling farmers, including the Redenbacher family, namesake of the famous popcorn brand. If you want to closely examine any one of the GIF frames, you can disable the animation and specify the frame number you're interested in.During the Great Depression, popcorn was fairly inexpensive at 5–10 cents a bag and became popular. In the options, you can also find a section about GIF frame delays, frame sizes, and frame counts. The "Animation Preview" option lets you see the input GIF with the original background and the output GIF with the removed background. This option works only in the browser and illuminates the removal areas using black and white pixels. To see exactly which pixels will be removed and which will remain, you can use the "Alpha Channel Preview" option. For example, the percentage 0% means match just one color and 20% means match 20% of similar color tonality. In this option, you can specify the percentage from 0% to 100%. If the background of your animation has various shades of the same color, you can remove them as well via the shade matching option. Similarly, if you enter a mathematical color value "#0000ff", the program will remove all blue pixels. For example, if you enter the color "yellow", the program will remove the yellow background from the animation. The area that will be removed from the GIF is selected by matching the specified color in pixels of the frames. When the background is deleted, you can download the transparent GIF right away. If your GIF has a single frame (it's static), then it deletes the background from just this one frame. ![]() If your GIF is multi-frame (it's animated), then it loops over all frames and deletes the background from every frame. This is a browser-based program that deletes the background color from all GIF frames. ![]()
