Abstract:
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.
