3.4.1. Temperature profile for chocolate chips during baking in sand
To confirm that chocolate chips baked in sand–fat mixtures melted
completely and broke temper during baking, the internal temperature
of the chip was recorded. Chocolate chips baked in plain sand with no
palm oil shortening reached 105.7 °C in 12 min and chocolate chips
baked in sand mixed with 13% palm oil shortening reached 102 °C.
The temperatures observed here were sufficiently high to completely
melt the chocolate chips. As a result, no crystal memory effect could
have occurred and any bloom inhibition on chocolate chips baked in
sand–fat mixtures was due to some other factor.
