Flour does not mix well with water. A chemist would say that the flour is suspended in the water. In a solution the chemical you add is called the solute and the liquid that it dissolves into is called the solvent. The root is milled or mashed into a powder (aka konjac flour), then boiled in water with lime (or another source of calcium hydroxide), which then turns the mixture into a gel. In a given batch of flour about 12% of the albumen is gluten forming protein and approximately 1% is water soluble albumen. Table 1 shows the relative amounts of dry material obtained in the water soluble and insoluble fractions of each treatment and how the flour components partitioned between the fractions. Small amounts of germ oil are expressed during milling, ending up in the flour. Flour does not mix well with water. As a result, a mixture of flour and water has a cloudy white appearance. More details on this subject can be found in " Baking, The Art and Science" , (6). With time and kneading, one can slowly work the water into the flour to create a dough. However, it must be completely diluted as it does contain some gluten and it will thicken as a result. When baking, replace some or all flour with whole-wheat flour… Treating navy bean flour with water at 23 °C partitioned 78.3 g/100 g and 21.7 g/100 g of the flour into the insoluble CI and soluble CS fractions, respectively. Over time, the flour will slowly settle toward the bottom of the beaker. Both of these are difficult to "whet" -- have poor wettability, so water does not readily mix without some prior preparation - the water will just "run off" of the flour. As a result, a mixture of flour and water has a cloudy white appearance. Flour is made up mainly of protein and starch granules. Soluble fiber dissolves in water, and includes plant pectin and gums. This is because flour does not dissolve in water. Over time, the flour will slowly settle toward the bottom of the beaker. The content of various water-soluble vitamins in flour is only 15% to 40% that in whole-wheat. We call substances that dissolve in water soluble. When you dissolve a soluble chemical in water, you are making a solution. This is because flour does not dissolve in water. Insoluble fiber doesn’t dissolve in water. Perhaps provide edible materials such as salt, sugar or flour. Spelt flour is soluble in water. You could also provide liquids such as milk, vinegar or oil and ask the children to comment on their solubility in water. Substances that do not dissolve in water are called insoluble. A chemist would say that the flour is suspended in the water. Sugar and salt are examples of soluble substances. Most of the vitamins are present in the bran and germ of the wheat kernel.
