Physicochemical, Thermal and Functional Characterization of Protein Isolates from Grain Activated Chickpea (cicer arietinum l.) Seed

Mr. Sajad Ahmad Sofi

Activation of Chickpea (Cicer arietinum L.) seeds by germination method is enrichment technique in protein fortification and new product formulation such as cereal products, healthy drinks and nutraceuticals. The main objectives of this study were to analyze the physicochemical, thermal and functional properties of control and germinated chickpea protein isolates (CPIs). Germination for 24 hrs increase protein isolate recovery of Chick pea seed of 21.17 g/100g while control has 20.53 g/100g. Protein content of germinated CPI also raised up to 86.93% than 85.29% in control one. Water, oil absorption and emulsifying property of CPI also increased by germination than the non germinated chick pea protein isolate. Chick pea protein isolate have lower bulk density 0.54 g/ml than the control one which have 0.47g/ml. The protein solubility at pH 4.5 of chick pea protein isolate is 14.14% while due to germination it is increased up to 21.63%. Thermal properties of the control and germinated CPI by differential scanning calorimetry shows different changes in onset temperature, peak temperature, end set temperature and enthalpies values. All these parameters of DSc thermo grams are lower in germinated treated chick pea seeds. The onset temperature in control is 91.79◦C while as in germinated 75.34◦C, peak temperature for control and germinated CPI are 105 ◦C and 98 ◦C respectively. Enthalpies of CPI 3.6 J g−1for control CPI while lower in germinated CPI 2.5 J g−1.
