PREPARATION AND CHARACTERIZATION OF FEW MALODOR MASKED NUTRIENTS

“The worse the taste or odor of the medication, the better the cure", was once the prevailing attitude. Today, changes in patient attitude and the development of numerous flavoring agents have reversed that opinion. Patients now expect and demand medications that are pleasantly, or at least tolerably, flavored. This is especially true with children to whom this are most often prescribed. In other words, an unpleasant odor in a formulation reduces patient acceptance, preference, and compliance for olfactory properties and there is no proper measurement technique/method for the same. So, it is very challenging to assess the odors and their evaluations. The selection of the nutrient is based on the odor and nutritional functions of the nutrients. Two methods for odor evaluation including Electronic nose method and sensory method. The electronic nose method is there but it is not the cost effective method and also not globally accepted. Subjectively direct rating for intensity or hedonic tone by sensory method is easier and cheaper method. Highly accurate methods are not always necessary, so sensory method is most convenient one. Particle coating is the process by which very tiny droplets or particles of liquids or solids material are coated with a continuous film of polymeric material can change the property of target particle. Mostly in powder particle coating process, the solution of coating is used. The pan coating process is the oldest industrial procedures for forming small, coated particles or tablets.
