Abstract

In order to study the correlation between electrical parameters and texture parameters, the electrical parameters of Ling-wu long-Jujube picked and stored at room temperature were measured dynamically at 25 frequency points in the scope of 3.16 kHz to 50.12 kHz with HIOKI 3532-50 LCR, and the sensitive electrical parameters and appropriate test frequency were screened out. Texture parameters such as pericarp strength, brittleness, pulp firmness, and hardness were measured by puncture test. The regression equation was established according to the correlation between electrical parameters and texture parameters. The results showed that the sensitive parameters of the complex impedance Z, inductance Lp and reactance X decreased in exponential form as the test frequency increasing; under the same frequency, Z, Lp and X increased as the storage prolonged. With its aging, jujube hardness, brittleness and pulp firmness decreased gradually while pericarp strength increased. Under the appropriate 3.16kHz testing frequency, electrical parameters and texture parameters have high correlation. The regression equations of hardness, brittleness, and pulp firmness were established, and their correlation with electrical parameters reached significant level (P < 0.05). Nondestructive testing of long jujube texture quality based on its electrical parameters is feasible.
