Place the moist soil sample in the container and again weigh it using balance as W2. /img0 73 0 R Place the dish with sample in the oven. DETERMINATION OF MOISTURE IN SOILS BY MEANS OF CALCIUM CARBID, EMBANKMENT AND BASE IN-PLACE DENSITY After a sufficient period, remove the sample from the oven and place it in the desiccator for cooling the sample. Cool down in the desiccator. AOAC. Weigh about 3 g of sample to the dish. 2. Recommended temperature is high enough to drive off most water content but low enough to minimize loss of other volatile compounds. Determine lipid content gravimetrically by measuring triplicate aliquots of the chloroform layer into tared containers, evaporate the solvent and weigh. USP 731 <loss on drying>, AOAC and ISO describe the thermogravetric method using a drying oven as a standard procedure for determining moisture content. Moisture affects the processability, shelf life, usability and quality of many products such as pharmaceutical substances, plastics and foods. 2.2 Method B This is an alternative moisture method which removes the total moisture in two steps: (1) evaporation of moisture in air at room temperature (air-drying), and (2) the subsequent oven drying of the air-dried sample at . The forced draft oven method is recommended for adoption as official, first action. The accuracy of results can be affected by temperature, relative humidity, amount of sample, particle size, and variation of temperature in the oven. In our collection of moisture methods for the food industry, you'll find over 20 moisture determination methods for samples in the food and bakery industry.

Homogenize the sample (20 g) with 16 ml of distilled water, 40 ml of chloroform and 80 ml of methanol at the speed of 9,500 rpm for 1 min at 4oC. 8 of this text. Use covered Al dish !50 mm diameter and <40 mm deep. 6. Remove receiver, wash tip of condenser and titrate excess standard acid distilled with standard NaOH solution. The LabX report generator enables you to create elegant reports with charts which can be printed out or saved electronically. Variables related to oven-drying samples of cheese and cheese products to determine moisture content were examined to provide more efficient and reproducible methods. >> Determination of the moisture content of a test portion by drying in an oven 6 h at 70 1 C under pressure < 100 mm Hg (13.3 kPa). jB`FJxjcB qv4;>[%5YR0IM@w}z@rBVcm] +JH"yuMOol/T/2k0e^O!r;U:,iS4-U.l#T0p+ar6=8XKBk4tEV[NMPsW7aga $'X%rmOLN`&}C|jh$pOF!.+_t!` \,zLzLH11d,(Lir=IcWuN( _,-aYS1.ma9'Haflm2DeG d05a`N^]FPj/
