Moisture content evaluation is very important in food business sequential to make sure baby bottle fridge and compulsory standards of food products. Basically the shelf life is highly related to the moisture proportion present in foods. Water content calculation should possibly help assessing the nourishment mostly with respect to the texture, taste and appearance to achieve better sensory evaluation. Carrying out processing nourishment shall need scientific knowledge within moisture estimation to determine food properties and their reactions during different processing for example freezing, packaging, heating, etc. Microbiologically nourishment are susceptible to microbial load in presence of considerable no.
Some sure nourishment are dried to make sure that protecting and extending their stability against bacteria; hence the need to conduct experiments to identify correct no. Chemically there exists multiple methods to estimate h2o percentage within distillation and stove drying. Distillation method it is generally based on Dean-Stark procedures in which a weighed sample added to a flask containing solvents with high boiling point, fewer density than h2o and immiscibility in h2o for example toluene. The content of flask is discharged through a condenser where it is subsequently distilled to a burette like distillation tube; solvent that is immiscible and decreased density stays on the top phase and the h2o remains at the bottom phase. Solvent returns to the original flask through an inclined tube linked between the burette and the fractionating column at the top regarding the flask.
Quantity regarding the collected h2o is then directly view on the graduated burette and proportionally calculated to work out the percentage of this value.
