**3.3 pH**

The obtained variations of the pH of the kiwi nectar irradiated at doses of: 0 (control); 0.5; 1.0; 2.0 kGy are in Table 1.

Is possible to observe that with the irradiation there was a decrease in the value of the pH, what resulted in more acid nectar, as increased with the dose of gamma radiation.

In agreement with Matsumoto et al. (1983), the pH value for the kiwi nectar should be around of 3.3. However, the sample that more approached this research was submitted to the irradiation with dose of 0.5 kGy.

Study accomplished by Leite; Gêa; Arthur; 2006 showed values of pH 3.38 for the samples irradiated in the doses of 1.0 and 2.0 kGy, and 3.41 for the sample no- irradiated. These values are same to the values found for in this research.
