저장 조건에 따른 마카롱의 저장 특성

Abstract

The purpose of this study was to evaluate the storage characteristics of macarons following storage under a range of conditions. Thus, the macarons were stored under three different sets of conditions, namely refrigeration (4°C), room temperature defrosting after freezing (−20→25°C), and refrigeration defrosting after freezing (−20→4°C), fillings were added during freezing. The volume, moisture content, and texture of each sample was determined, and sensory evaluations were conducted to identify the quality characteristics during storage. More specifically, in the case of the frozen samples, the volume was maintained at the beginning of the storage period, while in the refrigerated sample, the volume was maintained in the latter part of the storage period. In addition, the moisture content increased under all three conditions, and after three weeks, the highest moisture content was observed for the sample defrosted in the refrigerator after freezing. Examination of the textual properties (i.e., hardness, chewiness, and gumminess) showed increased values in the refrigerated sample, and reduced values in the frozen samples, whereby defrosting in the refrigerator gave the lowest value. In the sensory test, the overall acceptability was the highest for the sample defrosted at room temperature, resulting in the highest scores relating to color, nutty flavor, and nutty taste. Based on these results, it appears that when long-term storage is required, freezing in the presence of filling is considered optimal.
