Can you eat ice cream if it melts and then freezes?

May 26, 2023
The nutritionist of a program said that ice cream melted and refrozen will produce substances that are harmful to the human body, so it cannot be eaten. So is this a rumor or the truth? Can I eat ice cream after it is melted and refrozen?

Can you eat melted ice cream?

It is okay to eat ice cream after it is frozen. When the preservation temperature of ice cream increases, the ice crystals dissolve, the viscosity of the whole system decreases, and the small bubbles in the ice cream gradually merge into large bubbles until they overflow. After melting and refreezing, the ice cream loses its homogeneous state, which only affects the taste and is not harmful to human body.

Is melted and refrozen ice cream poisonous?

Melted ice cream is not poisonous. The process of freezing, melting and refreezing of ice cream only changes the physical state, but its chemical properties remain unchanged, so no new substances are produced, i.e. toxic substances as some people suspect.

Is there any bacteria in the ice cream after it is melted and refrozen?

Some people worry that ice cream will be easily contaminated by bacteria if it is frozen, but as long as the packaging of ice cream is intact, there will be no external bacteria in it. Moreover, the suitable temperature for bacteria to grow is 20-40℃, and generally ice cream melting will not reach this temperature.
