Glucose is a non volatile solute meaning it does not evaporate.
When it is added to a pure solvent such as water the resulting solution has a lower vapor pressure.
This implies that the freezing point of water is lowered.
Meaning if water freezes at 0°C, it might now freeze at - 10°C.
When a solution of glucose is frozen, Ice crystals are therefore observed first since the freezing point of water is lowered.
