Effect of different final frozen temperatures on Aralia elata( Miq.) seem's crystallization and texture

In order to explore the effect of final frozen temperature on Aralia elata( Miq.) seem's quality,frozen cooling curves surface crystallization and texture parameters were measured under-20,-30,-40 ℃ final frozen temperature. The results showed that the time dropped through maximum frozen crystal of Aralia elata( Miq.) seem 's under-20 ℃ final frozen temperature was about 120 s,and the data of the-30,-40 ℃ group was about 105 s. Aralia elata( Miq.) seem's surface crystallization under-30,-40 ℃ final frozen temperature was better than surface crystallization under-20 ℃ final frozen temperature. Friability,hardness and chewiness of Aralia elata( Miq.) seem under-20 ℃ final frozen temperature were decreased by about 30%,25% and 30%,these indexes of Aralia elata( Miq.) seem under-30,-40 ℃ final frozen temperature were by about 20%,15% and 15%.It is conclued that-30 ℃ was the best final frozen temperature for the Aralia elata( Miq.)seem.
