These spices have antimicrobial activity (with their active compounds):
The problem with these spices is that in order to have an effect at stopping bacterial growth, they need to be in high concentrations in the food. But at these high concentrations, they will overpower the other flavors in the food.
preservatives
No, hot spices will not prevent absorption of bacteria from food, nor will it prevent bacteria from growing on the food.
Spices were originally used to cover over the bad taste of rancidity and the early stages of food spoilage before the availability of refrigeration. Some spices (e.g. salt) were used to prevent food spoilage. Now we use them because we like the flavors and they make foods more interesting to eat.
To prevent food spoilage, methods like refrigeration, vacuum sealing, drying, canning, using preservatives, oxygen absorbers, and proper packaging are commonly used.
The recommended meat storage temperature to ensure food safety and prevent spoilage is below 40F (4C).
Three steps a housewife can take to prevent food spoilage would be first refrigerate leftovers. Second heat leftovers thoroughly and third not leave utensils in with the food.
Most bacteria, which cause food spoilage, cannot tolerate the high salinity. The salt draws out moisture, causing them to die.

The main way that pasteurization methods prevent food spoilage is by removing the bacteria from the food. This is done by heating the food until it is hot enough to kill the bacteria and then holding it there long enough to make sure that all bacteria are killed.

Salt and sugar act as preservatives by drawing out moisture through osmosis, which inhibits the growth of bacteria, yeast, and mold that cause spoilage.
