3.0 DETERMINATION OF MOISTURE CONTENT 3.1 Air-Oven Method 3.1.1 Definition: Moisture content of oils and fats is the loss in mass of the sample on heating at 105 ± 1°C under operating conditions specified. Because there is no simplis-tic and accurate way of determining absolute moisture con-tent, standardization of any method of analysis can be difficult. Imported Food Control Act 1992, and State and Territory Fair Trading Acts and Food Acts. 0000001925 00000 n
Microwave drying for food moisture content determination method, usually the convectional oven method but in some cases the Karl Fisher technique was used. The accurate measurement of water content is very important, as it affects all aspects of a business and itÕs supply chain. 0000003508 00000 n

Part 1: Determination of moisture content. According to ASTM D4442, oven drying can drive volatile compounds out of some species of wood. This International Standard applies to: wheat, rice (paddy, husked and milled), barley, millet (Panicum Moisture determination for food quality assessment Rolle F. 1,a , Beltramino G. 1 , Fernicola V. 1 , Sega M. 1 , Verdoja A. the total moisture per 100 g of the dry fraction. Differences in moisture content estimations varied from 0 to 6. It consists of 63-83% moisture content, 13-30% carbohydrate, 0.7-4.6% protein and 0.44% ash. When this occurs, the wood weighs less than if just the water had been removed. moisture content of a food can therefore be determined accurately by measuring the number or mass of water molecules present in a known mass of sample. WHITEPAPER Water Activity (a w) in Foods. 0000003939 00000 n
Moreover, potato is rich of vitamin and minerals such as vitamin C and B, calcium and phosphorus. … In principle, the moisture content of a food can therefore, be determined accurately by measuring the member or mass of water molecules present in a sample.

Since the amount of dry matter in a food is inversely related to the amount of moisture it contains, moisture content is of direct economic importance to … the total moisture per 100 g of wet sample, or in terms of dry basis, i.e. The water activity (a. w) of a food is a measure of availability of water for the metabolic activity and growth of microorganisms.

Determination of moisture content also is necessary to calculate the content of other food constituents on a uniform basis (i.e., dry weight basis). of moisture analysis for different food types must be investi-gated separately and thoroughly.

For routine determination of moisture or dry substance, the initial removal of water (5 hour drying period) may be accomplished in a vacuum oven at the specified temperature, using a water aspirator or other laboratory vacuum supply capable of maintaining a pressure of 50 to 75 torr.

Ivan KIRYAKOV. Accurate moisture content determination therefore plays a key role in ensuring quality in many industries including Food, Pharmaceuticals and Chemicals. Moisture content affects the processibility, shelf-life, usability and quality of a product. Product temperature increase is provided as a result of absorption of the microwave radiation by polar compounds of the product (mainly water). 11. METHOD HISTORY It's important to develop a moisture content determination method that will give you the same moisture content result as the official drying oven method. • Ovendry—A term applied to wood dried to constant weight in an oven maintained at temperatures of from 214 to 221°F. 0000027523 00000 n

For example, if the ambient air is at 70°F and 50% relative humidity, the relative humidity in the oven will be about 1% with an equilibrium moisture content of about 0.1 to 0.2%. METTLER TOLEDO has developed methods for a variety of samples from the food industry. When the moisture content is calculated, the value is too high.

The method described is applicable to the determination of Water Activity (a. w) for all food types at a constant temperature. Moisture content of the food material is important to consider the food is suitable before the consumption, because moisture content affects the physical, chemical aspects of food which relates with the freshness and stability for the storage of the food for a long period of time and the moisture content determine the actual quality of the food before consumption and to the subsequent processing in …
