| Abstract | ||
| The Results showed the chemical composition of protein isolated from lentil, chickpea and mung bean that have been obtained from the local markets of Kirkuk city agricultural season 2014-2015, using the upper extraction at pH 9.5, has been arranged at the point of the electric tie 4.5=pH the moisture content (4.90, 3.05, 2.90) % and ash content (2.50, 3.36, 2.30)% and protein content (82.37, 76.12, 79.37)% and the percentage of carbohydrates (10.23, 17.47, 14.53)% respectively. The results of estimate the solubility of the protein isolate when hydrogen figures ranging between (2-10) high printability when these figures hydrogen radical when hydrogen figures 10, 2 and you are a prima maximum when the number 10 where he (75, 73, 72) % and the lowest at pH and the values reached (7.20, 10.30, 9.00) respectively. The capacity Water absorption (1.9, 1.6 , 1.8) ml water ∕ gm of protein, fat absorption and portability (1.8, 2.1, 1.75) ml fat∕ gm of protein and emulsifying capacity and stability as reached (6.57, 14.28, 5.84)% respectively , while the stability of the emulsion was (97.36, 97.14, 98.21)% respectively. The study gave his best foam at different hydrogen figures included (4, 5, 6,7) the lowest power to foam at the number 4 ( 1.75. 3.75, 3.28)% and maximum values when the figure 7 ( 7.07, 12.76, 13.02)% respectively. The vegetable foam high at all times careless (2-0) and all samples under study showed the results of measuring the viscosity at different degrees of heat included (20, 30,40) C◦, it was (1.4)cp for the three samples isolated protein under study with a decrease in viscosity with a high degree of heat reaching (0.6, 0.86. 0.71) cp at a temperature of 40 C◦ respectively. | ||
