Table 3 shows the heat resistance evaluation, texture evaluation, and flavor evaluation results of the obtained cookie chocolate.
• a commercially available cookie table product name: Moonlight, manufactured by Morinaga Seika Co., Ltd.
• Example 5 to Example 9 Cookie-coating chocolate was obtained in the same manner as in Example 4 using the chocolate doughs 10 to 14 prepared in Prototype Examples 10 to 14.
• Table 3 shows the heat resistance evaluation, texture evaluation, and flavor evaluation results of the obtained cookie chocolate.
• Example 10-12 Cookie coating chocolate was obtained in the same manner as in Example 4 using chocolate doughs 15 to 18.
• Table 4 shows the heat resistance evaluation, texture evaluation, and flavor evaluation results of the obtained cookie chocolate.
• a dough viscosity suitable for coating can be obtained by using lecithin and PGPR in combination with a relatively low content.
• the later heat resistance and flavor were also good.
• For chocolate dough with a relatively high glucose monohydrate content of 21.4% to 28.9% it is necessary to use lecithin and PGPR together in a relatively high content, and the heat treatment temperature is set to a high value. Although necessary, the heat resistance and flavor after the heat treatment were good.
• the heat treatment temperature was changed to the following to obtain cookie-coating chocolate as in Example 4.
• Examples 14-15 The heat processing temperature of the chocolate dough 15 of Example 10 was changed into 80 degreeC and 110 degreeC, and heat resistance and flavor were confirmed.
• Table 5 shows the heat resistance evaluation and flavor evaluation results of Examples 14 to 15 and Comparative Examples 8 to 9. Table 5
• Example 14 No heat resistance was obtained at a heat treatment temperature of 70 ° C., and heat resistance was imparted at a heat treatment temperature of 80 ° C. in Example 14. At the heat treatment temperature of 110 ° C. of Example 15, the heat resistance was very good and the flavor and texture were good, but at the heat treatment temperature of 120 ° C. of Comparative Example 9, both the chocolate surface and the inside were hard and had a slightly burnt flavor. Met.
• Example 16 Using the chocolate dough 16, cookie-coating chocolate was obtained in the same manner as in Example 4. The obtained cookie chocolate was heated for 3.5 minutes using a far infrared heating device having a heater temperature of 250 ° C. to 260 ° C. Using a radiation thermometer (SK-800, manufactured by Sato Keiki Seisakusyo Co., Ltd.), the surface temperature of the cookie-coating chocolate taken out of the far-infrared heating device was monitored. It reached 88 ° C. after a minute. Then, it cooled in a 5 degreeC refrigerator for 1 hour, and obtained the heat resistant cookie coating chocolate. When the heat resistance of the obtained heat-resistant cookie-coating chocolate was evaluated after storage at 40 ° C., 7 days and 60 ° C. for 1 day, it was very good with no adhesion to the fingers or deformation at any temperature. In addition, both flavor and texture were good.
• SK-800 manufactured by Sato Keiki Seisakusyo Co., Ltd.
• Example 17 The heat treatment was performed in the same manner as in Example 17 except that the heater temperature of the far infrared heating device of Example 16 was changed to 360 to 370 ° C. and the heating time was changed to 1 minute. Similarly, when the chocolate surface temperature was monitored, it reached 80 ° C. at 50 seconds from the start of heating, and reached 90 ° C. after 60 seconds. Then, it cooled in a 5 degreeC refrigerator for 1 hour, and obtained the heat resistant cookie coating chocolate. When the heat resistance of the obtained heat-resistant cookie-coating chocolate was evaluated after storage at 40 ° C., 7 days and 60 ° C. for 1 day, it was very good with no adhesion to the fingers or deformation at any temperature. In addition, both flavor and texture were good.
