PROBLEM TO BE SOLVED: To provide a method for objective evaluation of drink in its carbonation.SOLUTION: There is provided a method for evaluation of "carbonation" in drink composition; comprising step (A) described below and at least one step selected from a group consisting of (B-1) and (B-2): step (A) obtaining swallowing sound generated when a subject swallows the drink composition; step (B-1) carrying out frequency conversion for signals of a flow sound region (t) in the obtained swallowing sound, and calculating average sound pressure (P) in a specific frequency region within a range of 3 kHz to 8 kHz; and step (B-2) carrying out frequency conversion for signals of a flow sound region (t) in the obtained swallowing sound, and calculating appearance frequency (F) from change in sound pressure at specific frequency within a range of 3 kHz to 8 kHz.SELECTED DRAWING: Figure 1【課題】飲料についてその炭酸感を客観的に評価するための方法を提供する。【解決手段】下記に示す(A)の工程と、(B-1)及び(B-2)よりなる群から選択される少なくとも一つの工程を有する、飲料組成物の「炭酸感」を評価する方法。(A)被験者が飲料組成物を嚥下した際の嚥下音を取得する工程、(B-1)取得した嚥下音のうち流動音領域(t2)のシグナルを周波数変換し、3kHz~8kHzの範囲にある特定周波数領域の平均音圧(P3-8)を算出する工程、(B-2)取得した嚥下音のうち流動音領域(t2)のシグナルを周波数変換し、3kHz~8kHzの範囲にある特定周波数の音圧変化から音の出現頻度(F3-8)を算出する工程。【選択図】図1
