Abstract:In order to evaluate the quality stability of edible flavor microcapsules，the physical，textural and breaking sound properties of six kinds of self-made edible flavor microcapsules（preset dimeter=2.5 mm and 3.5 mm）before and after moisture absorption were determined.The results showed that the smaller the preset microcapsule diameter，the larger deviation the practical diameter was observed，which might be related with the production method and compatibility between the wall material and core materials.Before edible flavor microcapsules moisture absorption，the mean value of broken force was ranged in 10.04 N-17.78 N，and the mean value of maximum deformation ratio was ranged in 33.5%-46.5%，both with great difference but also large standard deviation；the mean value of broken sound intensity was ranged in 76.9 dB-83.8 dB，with certain difference and small standard deviation.After moisture absorption，lower，unchanged，and higher mean value of broken force were all observed in samples；the mean value of maximum deformation ratio was significantly increased but still with large standard deviation；the breaking sound intensity was significantly lowered with small standard deviation.These results indicated that，compared with the textural properties of microcapsules，the breaking sound intensity could better reflect the quality fluctuation during storage，and could be used as one judge indicator for quality evaluation of edible flavor microcapsules.
