![]() ![]() Low viscosity substances have smaller molecules with weak intermolecular forces. For example, the large sugar molecules in honey have strong hydrogen bonds holding them together, whereas the individual molecules of water have weaker hydrogen bonds that break more easily. ![]() High viscosity substances are characterized by large individual molecules with strong intermolecular forces that inhibit movement. Examples of high viscosity substances include honey, molasses, pudding, ketchup, and shampoo, while substances with low viscosity include water, rubbing alcohol, and vegetable oil. Generally speaking, high viscosity substances are thicker and more resistant to flow than low viscosity substances. Viscosity is a measure of a substance’s resistance to flow. Corn syrup is typically a golden syrup and has less intense sweetness than pure white sugar, so it often is used to add body and texture to products. It also can be used to add sweetness and a glossy finish to products. This makes a thick substance that can be used in a variety of recipes, such as candy and baked goods. Corn syrup is made from the starch of corn, usually by heating and breaking down the starch in water. It has a consistency that is thicker and more viscous than pure sugar, but less viscous and thicker than honey. Is corn syrup thick or thin?Ĭorn syrup is a viscous, relatively thick syrup. The viscosity of syrup typically ranges anywhere from 1,000 to 10,000 mPa This type of syrup is referred to as a colloidal solution and is highly viscous. ![]() The sugar molecules interact with each other and with the water molecules in the syrup, forming a solution that is more viscous than either the sugar or the water are on their own. The high viscosity of syrup is the result of its high sugar content. Its viscosity is typically classified as a Newtonian fluid, which is a type of fluid in which the viscosity does not change with pressure or shear rate. The increased viscosity also prevents the syrup from crystallizing, which helps improve the shelf life of products containing corn syrup.Īdditionally, the viscosity of corn syrup helps maintain a product’s texture, stability and consistency by trapping air, promoting stability by keeping the ingredients from separating, and generating a moist texture. These long, unbranched chains add viscosity to the syrup, meaning it has a thick, syrupy consistency when at room temperature.Īs the concentration of glucose molecules increases, the viscosity of the syrup increases because of the increased numbers of interlocking chains. Why is corn syrup so viscous?Ĭorn syrup is so viscous because it contains long, unbranched chains of glucose molecules. Therefore, depending on the specific corn syrup product you are looking for, the viscosity can vary significantly. These products typically range in viscosity from 2000 cP to 15000 cP. For applications where a higher viscosity is required, a specialized high viscosity corn syrup is available. The average viscosity of corn syrup can range from 1000 cP (light corn syrup) to approximately 9500 cP (dark corn syrup).Ī light corn syrup would have an average viscosity of 1000 cP, while a dark corn syrup would have an average viscosity of 9500 cP. Generally, the more concentrated the corn syrup, the higher the viscosity. The viscosity of corn syrup is a measurement of the product’s resistance to flow.
