Abstract:Toobtainanoptimal sugar infiltration method forthepreparationof preserved passion fruit,thispaper investigatestheultrasonic-asistedandmicrowave-assistedsugarinfitrationtechnologiesonthesensoryscore,colotexture characteristics,totalsugarcontent,totalphenolcontentandvitroantioxidantcapacityofpreseredpasionfruit,adoptingthe conventional sugar infiltration method as a control.The results show thatthe sensory scores (82.67),hardness (343.02/g) , chewiness (114.31/mJ) ,gelatinization (189.71/g) ,total sugars (58.73%) ,total phenols (3.8mgGAE.g-1) )andDPPHfree radical scavenging ability (86.83%) )ofthepreserved fruitsare increased significantly (P<0.05) by ultrasonic-assisted sugar infiltration method 50min )in comparison with the conventional and wave-assisted technologies,whereas the difference of brightness and hydroxylradical scavenging ability between conventional and ultrasonic group are not significant (P>0.05) : Hence,the ultrasonic-assisted sugar infiltration method ( 50min )is more suitable for the production of preserved passion fruit.
