TLDR;
Sim. O açúcar inibe o crescimento do molde.
Como isso funciona?
Várias razões:
- O açúcar proíbe o crescimento por meio da osmose / desidratação.
"The most notable is simple osmosis, or dehydration. Salt or sugar, whether in solid or aqueous form, attempts to reach equilibrium with the salt or sugar content of the food product with which it is in contact."

- O açúcar enfraquece a estrutura molecular do DNA dos patógenos
Salt and sugar's other antimicrobial mechanisms include interference with a microbe's enzyme activity and weakening the molecular structure of its DNA. Sugar may also provide an indirect form of preservation by serving to accelerate accumulation of antimicrobial compounds from the growth of certain other organisms.
