20. Calculate the % IDF value.
% IDF = [(R
1
+ R
2
)/2] ‐ P ‐ A ‐ B
(M
1
+ M
2
)/2
= [(( f
F1
‐ f
S1
) + ( f
F2
‐ f
S2
))/2] ‐ P ‐ A ‐ B
(M
1
+ M
2
)/2
Where: M
1
, M
2
= Original wt of duplicate samples adjusted for pre ‐ treatment fat and sugar losses (g)
R
1
, R
2
= Residue for duplicate samples (g)
f
F
= Final Filter Bag with residue (g)
f
S
= Initial Filter Bag (g)
P = Protein of residue and bag (g)
A = Ash of residue and bag (g)
B = Blank (g)
= [(BR
1
+ BR
2
)/2] ‐ P
B
‐ A
B
= [(( f
BF1
‐ f
BS1
) + ( f
BF2
‐ f

))/2] ‐ P
B
‐ A

= Residue for duplicate blanks (g)
f
BF
= Final Blank Filter Bag (g)
f
BS
= Initial Blank Filter Bag (g)
P

= Protein of Blank Filter Bag (g)
A
B
= Ash of Blank Filter Bag (g)
21. Calculate the % SDF value.
% SDF = [(R
1
+ R
2
)/2] ‐ P ‐ A ‐ B
(M
1
+ M
2
)/2
= [(( f

‐ D
2
))/2] ‐ P
1
‐ (A
2
‐ D
2
) ‐ B
(M

+ M
2
)/2
Where: M
1
, M

, R
2
= Residue for duplicate samples (g)
f
F
= Final Filter Bag with residue (g)
f
S
= Initial Filter Bag (g)
D = Original wt of Diatomaceous Earth (g)
P = Protein of residue and bag (g)
A = Ash of residue and bag (g)
B = Blank (g)
= [(BR
1
+ BR

)
= [(( f

))/2] ‐ P
B1
‐ (A

‐ D
B2
)
BR
1
, BR
2
= Residue for duplicate blanks (g)
f
BF
= Final Blank Filter Bag (g)
f
BS
= Initial Blank Filter Bag (g)
P
B
= Protein of Blank Filter Bag (g)
A
B
= Ash of Blank Filter Bag (g)
D
