A light emitting control apparatus comprises a light emitting element which emits a light when an input electrical signal is converted into a light signal, a monitoring circuit which monitors the output level of the light emitting element, a sample-and-hold circuit which detects a peak value and is put into the sample mode when data of the monitoring circuit is in the mark state showing voltage and which is in turn put into the hold mode when the data is in the space state showing no voltage, and an amplifier which accomplishes negative feedback control of the output level of the light emitting element by using the output of the sample-and-hold circuit. Thus, the apparatus can quickly respond to a change of the input state and stabilize the output level of the light emitting element for a long time.

A cocoa butter substitute comprises sal fat obtained by extracting the fat from the seeds of Shorea robusta and then refining the resulting product. The cocoa butter substitute has a hydroxy value of not more than 16, a solid fat index of not less than 48 at 30.degree. C., a cooling time, at which the maximum point appears in the cooling curve, of not longer than 120 mins. and the maximum point temperature of not less than 17.degree. C.
