Therefore, the dextrose equivalent describes the degree of conversion of starch to dextrose. The standard method of determining the dextrose equivalent is the Lane-Eynon titration, based on the reduction of copper(II) sulfate in an alkaline tartrate solution, [1] an application of Fehling's test. Examples: A maltodextrin with a DE of 10 would ...
Fehling's can be used to screen for glucose in urine, thus detecting diabetes. Another use is in the breakdown of starch to convert it to glucose syrup and maltodextrins in order to measure the amount of reducing sugar , thus revealing the dextrose equivalent (DE) of the starch sugar .
For example, an 11.0% by mass D-Glucose ("grape sugar") solution measured 10.9 °Bx using a hand held instrument. [ citation needed ] For these reasons, the sugar content of a solution obtained by use of refractometry with the ICUMSA table is often reported as "Refractometric Dry Substance" (RDS), [ 9 ] which could be thought of as an ...
Maltodextrins are classified by a dextrose equivalent (DE), [5] [6] a number between 3 and 20 that corresponds to the number of free chain ends in a certain sample. A lower DE value means the polymer chains are longer (contain more glucose units) whereas a higher DE value means the chains are shorter. [6]
Glucose syrup was the primary corn sweetener in the United States prior to the expanded use of high fructose corn syrup production in 1964. [14] HFCS is a variant in which other enzymes are used to convert some of the glucose into fructose. [15] The resulting syrup is sweeter and more soluble. [citation needed]
D50 – 50% dextrose in water; The percentage is a mass concentration, so a 5% glucose/dextrose solution contains 50 g/L of glucose/dextrose (5 g per 100 ml). This usage is imprecise but widely used, as discussed at Mass concentration (chemistry) § Usage in biology. Glucose provides energy 4 kcal/gram, so a 5% glucose solution provides 0.2 kcal/ml
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
Glucose vs. plasma glucose: Glucose levels in plasma (one of the components of blood) are higher than glucose measurements in whole blood; the difference is about 11% when the hematocrit is normal. This is important because home blood glucose meters measure the glucose in whole blood while most lab tests measure the glucose in plasma.
