速冻终温对刺嫩芽水分结晶及质构的影响

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

  • 摘要: 为了探究速冻终温对刺嫩芽品质的影响及确定最佳的速冻终温,实验设定-20、-30、-40℃不同的速冻终温,测定不同速冻终温下刺嫩芽的速冻降温曲线、刺嫩芽表面水分冰晶结晶状态及质构参数。结果表明:-20℃速冻终温的刺嫩芽通过最大冰晶生成带的时间大约为120 s左右,-30、-40℃速冻终温的刺嫩芽通过最大冰晶生成带的时间大约为105 s左右;-30、-40℃速冻终温的刺嫩芽的表面水分冰晶结晶状态优于-20℃速冻终温刺嫩芽的表面水分冰晶结晶状态;-20℃速冻终温的刺嫩芽的脆度、硬度和咀嚼度下降率大约为30%、25%和30%左右,-30、-40℃速冻终温的刺嫩芽的脆度、硬度和咀嚼度下降率大约为20%、15%和15%。-30℃为速冻刺嫩芽的最佳速冻终温。 

     

    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.
