Question

What is the amount in g of digestible carbohydrate in 100 g of the chicken? answer is 9.08 g but I have no idea how to get that answer.

What is the caloric content of 100 g of the product? answer is 271.5 kcal/100 g

Constituent	%
Fat	16.53
Protein	21.61
Digestible CHO (by difference)	?
Ash	0.98
Water	51.50
Fiber	0.30

Answer 1

If 16.53 % of 100g is fat then 0.1653g is fat

Similarly, Protein is 0.2161g

Water is 0.5150

Fiber is 0.0030

Ash is 0.0098

Add these up and substract from 1 i.e. 1-0.9092 which is 0.0908 g

Multiply this with 100 you get 9.08% of 100 g is Carbohydrates

Caloric content for individual component

4 Kcal/g for protein, 4 Kcal/g for carbohydrate, and 9 Kcal/g for fat

Caloric content due to fat:0 .1643*9 = 1.4877 Kcal

Caloric content due to protien: 0.2161*4= 0.8644 kcal

Caloric content due to carbs: 0.0908*4= 0.3632 Kcal

Total:                                                       2.7153 Kcal

For 100g, 2.7153*100 = 271.5Kcal
