<v Speaker 1>Welcome to brain Stuff from how stuffworks dot com where

0:00:03.840 --> 0:00:16.919
<v Speaker 1>smart happens Hi Marshall Brain. Most people eat bread every

0:00:16.920 --> 0:00:20.320
<v Speaker 1>single day, but have you ever thought about how bread works.

0:00:20.880 --> 0:00:24.439
<v Speaker 1>Bread is a technology for turning hard wheat kernels into

0:00:24.560 --> 0:00:28.319
<v Speaker 1>something soft, airy, and delicious. One thing you need for

0:00:28.360 --> 0:00:31.360
<v Speaker 1>a good loaf of bread is yeast. Yeast is a

0:00:31.400 --> 0:00:35.600
<v Speaker 1>fungus that each sugar and produces carbon dioxide and alcohol.

0:00:36.200 --> 0:00:39.440
<v Speaker 1>In bread, you want to trap the carbon dioxide bubbles.

0:00:39.800 --> 0:00:43.040
<v Speaker 1>The wheat and bread contains something called gluten, which is

0:00:43.080 --> 0:00:46.760
<v Speaker 1>a stretchy substance a little like bubblegum. The reason why

0:00:46.840 --> 0:00:49.600
<v Speaker 1>you need bread dough is to develop the gluten and

0:00:49.640 --> 0:00:53.840
<v Speaker 1>link the molecules together. Once the yeast starts producing bubbles,

0:00:53.880 --> 0:00:57.279
<v Speaker 1>the dough catches the bubbles in little gluten balloons and

0:00:57.360 --> 0:01:01.400
<v Speaker 1>starts to rise. Gluten is approach. When you cook bread,

0:01:01.440 --> 0:01:04.520
<v Speaker 1>the protein heats up and set it firms up like

0:01:04.560 --> 0:01:08.520
<v Speaker 1>an egg does when you cook it. Be sure to
