This study was aimed to characterize the physicochemical and protein of the dry seed of lima bean from Indonesia based on its solubility, electrophoretic pattern, and amino acid profile.

The fat content (1.15±0.04%) was low and ash (3.67±0.47%) comprised of magnesium, phosphorus, potassium, calcium, and iron with the content of 184, 75, 38, 11, and 10 mg/100 g, respectively. Total phenolic compounds of this seed were 1.29±0.02 mg/g, phytic acid 11.57±0.03 mg/g, saponins 16.84±0.42 mg/g, and trypsin inhibitors 36.07±0.11 TIU/g.

Protein content was moderate (15.93±0.55%) that comprised of albumin 18.47±0.62%, globulin 56.20±2.00%, prolamin 3.14±0.20%, and glutelin 22.69±1.60%.

Lima bean (Phaseolus lunatus L) is native to Latin America and has spread out worldwide, thus having a high level of diversity. The lima bean seed from a specific region might have different characteristics from others. This study was aimed to characterize the physicochemical and protein of the dry seed of lima bean from Indonesia based on its solubility, electrophoretic pattern, and amino acid profile. The result showed that carbohydrate (68.89±1.55%) was the major component, with starch (41.96±1.10%) as the predominant. The amylopectin was higher than amylose.
