for 15 minutes under the condition of 25°C of
temperature and 60% of relative humidity to make the
surface of the chocolate-like food dew condensation. The
20 block of พีพี or the chocolate-containing food product was put into a gusset bag and the bag was sealed. The chocolate-containing food was stabilized at 20°C for 1 day, and then stood in constant-temperature oven
at 40°C for 1 day. After the standing, the presence or
absence of adhesion to fingers was checked by touching
fingers to the chocolate surface, and the presence or
absence of oil-off and change of shape was checked. Also, the presence or absence of adhesion of the chocolate to the gusset bag was checked.
