How many hours can candy last at 45 degrees?

As long as the weather is hot, it will melt and stick together.

When the average temperature in summer and autumn is above 30℃ and the humidity is high, the shelf life of all kinds of jelly candy is not more than 12 months, and that of hard candy is not more than 12 months.

The shelf life of pressed/polished sugar is mainly affected by humidity. When the package is well sealed, the shelf life can reach 18~24 months.

Expired sugar is prone to oxidation reaction, energy decline, breeding all kinds of bacteria.

If you want to keep it for a long time, first add a bag of desiccant to the candy and make three or four layers of vacuum seal.

(Equipped with professional vacuum sealing machine and extra-thick special sealing bag).

This ensures that if the first floor is broken, there will be several times inside. Moreover, even the best sealed bag will have a slight air leakage! So a few more floors are safer! Then: put it in the storage room of the refrigerator (ensure its temperature, humidity and environmental state are balanced)!

Also: regularly observe whether there are any preservation problems! (for example, the water ran away, the power went out, and so on. Although these problems rarely appear at ordinary times, you should pay attention to them! ) Well, this will ensure your long-term preservation.
