(1)融液状チョコレート生地に含まれる固形粒子の粒子径(D90)
粒度分布測定装置(例えば、株式会社島津製作所製、装置名:SALD-2300)でレーザー回折散乱法(ISO133201,ISO9276-1)に基づいて、湿式測定により測定した値(D90:粒度分布における積算値90%の粒径の測定値)とした。
(2)融液状チョコレート生地の粘度
融液状チョコレート生地の粘度(単位:mPa・s)は、BH型粘度計(東機産業社製)を使用して測定した。つまり、No.6のローターを回転数4rpmに設定した。次いで、測定温度に調温したチョコレートの中で、ローターを3回転させて数値を読み取った。読み取った数値に装置係数(2500)を乗じて粘度を求めた。
(3)チョコレートの水分
チョコレートの水分(水含有量)は、常法に従い、常圧乾燥減量法により測定した。
(4))n-ヘキサン浸漬試験(耐熱保形性)
長間隔16mm、短間隔8mmで60°と120°で交差する菱形のステンレスネット上にチョコレートを載せ、20℃でn-ヘキサン中に浸漬し、経時的にネットの上に残存するチョコレートの抽出残渣の有無、及び、その形状の観察を48時間にわたって下記の基準に基づいて評価した。チョコレートの形状が保持されているほど、糖によるネットワークの形成がより強固になされていることを示す。
◎ 元の形状が完全に残っている
○ 一部崩れているが元の形状が残っている
△ ネット上に残渣が残っているが、形状が崩れている
× ネット上から残渣が完全に落下し、形状が完全に崩れている
