Ungelatinized starch
WebWhen ungelatinized starch is viewed under a microscope with a polarized light, the intact crystalline structure of the starch refracts the light in a "Maltose Cross" pattern. What is the correlation between this "Maltose Cross" pattern with the gelatinization of the starch? General guidance ...

Advantages of this method are the use of small amounts of sample, less reagents, and elimination of … Gelatinized starch, when cooled for a long enough period (hours or days), will thicken (or gel) and rearrange itself again to a more crystalline structure; this process is called retrogradation. During cooling, starch molecules gradually aggregate to form a gel. The following molecular associations can occur: amylose … See more Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. … See more A simple technique to study starch gelation is by using a Brabender Viscoamylograph.
