Physical analysis of honey:
Physical analysis of honey is one of the methods that the buyer avoids being cheated on. Reveals the type of honey and the quality of the honey. Honey is a sugary substance that honey bees extract from the nectar of flowers and then bees store it in their honeycombs.
Physical testing of honey and analysis of honey
A physical analysis of honey must be performed to ensure the validity of honey and not adulterate it in some way, for example in the event. The honey was picked and a ripe genie. It was mixed with another type of honey to ensure that it is free from contamination. Or it was stored incorrectly for a long time until honey lost some of its compounds. For this, you may give us some tests are matters that make judging honey difficult and require the use of several tests. Including the physical examination of honey.
Methods of physical analysis of honey:
The physical analysis of honey depends on many things. Methods of physical analysis of honey can be summarized in the following ways:
Calculate density ratio estimate:
Or what is known as specific weight, which is a physical characteristic of objects that expresses the relationship between the volumetric mass of an object?. The volumetric mass of pure water. The average density of an object equal to the weight of a given volume of the substance divided by Weighs the same volume of water at the same temperature. Therefore, it has no unit but rather a number indicating a ratio.
Calculate acidity degree (PH):
PH is a number that chemists use to indicate the concentration of hydrogen ions in a solution. To determine whether a liquid is an acid, a base, or a neutral. It generally ranges from 0 to 14. Where liquids have an acidity of fewer than 7 acids, while liquids with a pH higher than that are bases. For the pH of 7, it is considered neutral. The pH of a substance is measured by means of the pH scale. It usually consists of a special electrode connected to an electronic scale and equipped to measure the potentials calibrated to the unit of pH, Where the electron is immersed in the solution to be measured. The value is read directly from the device after being fixed. The device must have an accuracy of up to 01.0 units.
Measurement of electrical conductivity values:
Electrical conductivity is a property of a substance. It is a numerical convention for the affinity of an aqueous solution. The transmission of an electric current. This ability depends on determining the number of electrolytes that are able to transfer electricity in honey. It is measured at different temperatures of honey solutions with a concentration of 10%, by means of a Conductometer to measure electrical conductivity. A transport cell consists of an electrode covered with a glass mold and a plastic material dipped in Honey solution to be measured.
Calculation of qualitative rotation:
This method can be applied to all honey samples in particular. It uses polymeric methods. To measure the concentration of simple sugars in solutions, depending on the degree of deviation of the level of polarized light. As a result of the presence of heterocyclic carbon atoms in the molecule whose value is proportional to the concentration, the polarized light. The outlet of the solution will deflect or rotate at a certain angle to the right (+) or left (-) of the original level. It rotates linear polarized light to the right. Fructose causes it to rotate polarized light to the left by the effect of glucose to the right is greater than the effect of glucose to the right. So, we find in honey solutions the greater the deflection value of the polarized light. To the left, the higher the fructose content in honey.
Calculation of chromatic intensity:
The color intensity of honey is determined according to the Pfund scale after measuring the absorption of light rays. For honey solution using a UV device at wavelengths of 635nm and 560nm. per classification U.S Agriculture classification USDA intensity chromaticity.
