Proximate analysis of fried red kidney bean tempeh
The following AOAC [7] methods were used to determine proximate composition: drying at
1050C for 24 h for moisture (method 925.098); incineration at 5500C for ash (method 923.03);
defatting in a Soxhlet apparatus with petroleum ether for crude fat (method 920.39C);
microkjeldahl for crude protein (N× 6.25) (method 960.52); and determined gravimetrically after
chemical digestion and solubilization of other materials present. The fibre residue weight is then
corrected for ash content after ignition carbohydrate content was estimated by difference.
