Lactose is a disaccharide carbohydrate. It is formed by condensation of glucose and galactose, β-(1→4) linked. Lactose is produced in plant and animals. In plant it is used as a storage of carbohydrate in a seed. In animal it is produced as a part of milk in mammals.
Cellulose is an organic compound that is found in plants. Cellulose is described as a complex carbohydrate which is made up of carbon, hydrogen and oxygen. Microcrystalline cellulose is a good excipient in drug formation.

Stearic acid is also known octadecanoic acid in its IUPAC name. It is saturated fatty acid with 18-carbon chain. It is found in nature in enormous quantity. As stearic acid has wax-like nature it is used as emulsifying and solubilizing agent in

The mixed components can be separated and analysed. There are different methods to do so. One of them is chromatography. There are different types of chromatography, TLC, HPLC, GC and so on. However, all of them agree in their two phases, stationary and mobile. Stationary phase remains fixed in place where the mobile phase moves over it. Among the chromatography methods, TLC will be used to a lactose raw material in this experiment. TLC is the short form of Thin Layer Chromatography. TLC is the simplest, inexpensive, and also time saving chromatography. It possesses three main parts, jar, mobile phase and plate. The TLC jar is just a container of mobile phase. The mobile phase is prepared in different polarity based on the nature of compound that going to be treated. The TLC plate can be any sheet of metal or plastic that is coated with a thin layer of solid adsorbent. Most often the thin layer used for TLC plate is either silica or alumina. TLC works by placing a chosen polarity of a reasonable volume of mobile phase in the TLC jar. A TLC plate contains the spot of the analysed/standard components near the bottom of it is placed in the jar. When the mobile phase rises up gradually to the top of the plate, the components spotted migrate along with the mobile phase until they get absorbed by the stationary phase. The position of component to get absorbed on the stationary phase depends…show more content…
Optically active is also called specific rotation, [α]. This occurs when there is at least one asymmetric centre, usually carbon with four different substituents. Optically active compound does not have non-super impossible image. Specific rotation is given by: α (rot) = αobs/c.l
However, the Polarimeter which will be used in this experiment to analyse the specific rotation of lactose raw material, can calculate and display the specific rotation automatically.

Loss on drying test is a method of evaluating the presence of water and volatile matters in a sample by drying the sample under specific condition.

Viscosity is simply a measurement to describe how a given fluid is resistant to flow. A large viscosity resists motion because its molecular makeup gives it a lot of internal friction, and a small viscosity less resists
