LOD is that the loss throughout drying of sample as per prescribed conditions which supplies loss (presence) of all evaporating solvents together with water.It is the dry base.
While water content provides the moisture present within the sample solely.
It is unhydrous base.
LOD: Loss on drying......MC: Moisture content..... By using LOD we messures Accurate weight of the Compound... i.e..Loss of Solvents ,Moisture Present in that compound at the bellow of that compound Melting point.. MC: By using moisture content we just messures about the moisture of the compound..
Drying rate is not constant throughout the drying process. Drying rate generally decreases with the decrease of free moisture content. ( water in food is present in different forms; bound and unbound.Its easy to remove unbound moisture. In a drying curve, there's a constant rate drying period and a falling rate drying period. Depending on the equilibrium moisture content, critical moisture content and the final moisture content there are different formulas for calculating drying rates.
drying agent absorbs the water content while dehydrating agent lost the water content.
if we know initial moisture content of the object we can identify how much drying energy required for dry the same moist material. if it is a food material we have to reduce the moisture content upto certain level, otherwise it may be destroyed. if we know the initial moisture content of same food object, we can reduce its moisture content upto 10% of its initial moisture content.
2 to 19 ml/g of onion
Drying agents absorb the moisture contents from a substance, where as dehydration removes the water molecules, hence totally a new product is formed
Kiln drying
High level of heat will affect the nutrient content, moisture too.
Karl Fisher Titration measures only the water content in a product sample. Loss on drying measures the total loss in weight of a material as a result of drying.?æ
I is the differential between the temperature and moisture content of the object being dried and the surrounding atmosphere in which it is located. The drier and hotter the atmosphere the faster something will dry.
The moisture content can be calculated by weighing the fruit and then placing it in a drying oven for a definite period of time then removing and weighing again. If you continue this until there is no more loss of weight. The initial weight minus the final weight is the weight of water. this difference multiplied by 100 and divided by the initial weight will give you the percent moisture content.
2 ounces (if all that was lost in the drying process was moisture).
