The analysis of honey shows: [3] Typical honey analysis. Fructose: 38%; Glucose: 31%; Sucrose: 1%; Water: 17%; Other sugars: 9% (maltose, melezitose) Ash: 0.17%; In this example the ash would include all the minerals in honey. Ashing is also performed prior to chemical analysis by inductively coupled plasma emission spectrometry.
Substance in water + 3 mL Benedict's solution, then boil for few minutes and allow to cool. Red, green, or yellow precipitate is obtained Reducing sugar, such as glucose, is present Substance in water + 3 mL Benedict's solution, then boil for few minutes and allow to cool. Solution remains clear or is a little blue Reducing sugar is not present
Glucose oxidase is widely used for the determination of free glucose in body fluids (medical testing), in vegetal raw material, and in the food industry. It also has many applications in biotechnologies , typically enzyme assays for biochemistry including biosensors in nanotechnologies .
A sucrose solution with an apparent specific gravity (20°/20 °C) of 1.040 would be 9.99325 °Bx or 9.99359 °P while the representative sugar body, the International Commission for Uniform Methods of Sugar Analysis (ICUMSA), which favours the use of mass fraction, would report the solution strength as 9.99249%. Because the differences between ...
Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent.It is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.
Gemstones are transparent minerals and can therefore be examined using optical methods. Refractive index is a material constant, dependent on the chemical composition of a substance. The refractometer is used to help identify gem materials by measuring their refractive index, one of the principal properties used in determining the type of a ...
Creamed honey is honey that has been processed to control crystallization. Also known as honey fondant, [1] soft set honey, or whipped honey, it has a smooth, spreadable consistency and lighter color than liquid honey of the same floral type. A method for producing creamed honey was first patented in 1935, and other methods have since been devised.
The Trinder glucose activity test is a diagnostic test used in medicine to determine the presence of glucose or glucose oxidase. The test employs the Trinder reagent , and is a colour change test resulting from the Trinder reaction .
