How do you calculate fat on dry matter basis?

Feb 19, 2020 To calculate the protein on a dry matter basis, you remove the water, so 100 g powder – 5.3 g water = 94.7 grams of dry matter. You convert from “as is” to DMB by taking the percentage protein on a DMB basis and dividing by the new percentage of dry product: % protein DMB = as is protein / (1- % water).

oven dry weight of the wood Oven dry weight is the quasi-constant weight attained by wood sam- ples dried at 105 co (221 F 0). As pointed out by MacLean (1952) and Stamm (1964), it is advantageous to define moisture content in terms of the oven dry weight of the wood since the oven dry weight is a constant value that may be determined at any time.

Correct soil weight from air-dry to oven-dry

The calculation of the air-dry to oven-dry, or AD2OD, ratio is used to adjust all sample weights to an oven-dry basis. To calculate the sample weight that is equivalent to the oven-dry soil weight the AD2OD ratio is applied. When a soil is sampled it is spread out and dried to air dry moisture content. The exception to this is when drying the ...
