In the scorching summer heat, ice cream becomes one of people's favorite treats to beat the heat. However, many have experienced the awkward situation of ice cream melting rapidly in high temperatures.

To solve this problem, people have continuously sought methods, from scientific principles to creative designs, to explore the mystery of keeping ice cream from melting easily. In this article, we will explore some effective methods and techniques to keep your ice cream cool during the summer.

1. Improving Ice Cream Formulation

The formulation of ice cream is one of the key factors affecting its melting rate.

Traditional ice cream recipes typically include fats, sugars, and water. Adjusting the proportions of these ingredients can improve ice cream's resistance to melting. For example, increasing the fat content can enhance the creaminess of ice cream, making it more stable in high temperatures.

Additionally, adding stabilizers and emulsifiers can improve the texture and stability of ice cream. Sugar alcohols such as sorbitol and xylitol can reduce ice crystallization, thereby slowing down its melting rate.

2. Freezing Techniques

Proper freezing techniques can ensure that ice cream cools evenly, thus slowing down its melting rate. When making ice cream, it's crucial to minimize air bubbles in the mixture, which can decrease ice crystallization and enhance stability.

Furthermore, placing ice cream in the coldest part of the freezer can expedite the freezing process, resulting in a more uniform texture and slowing down the melting rate.

3. Packaging Design

The design of ice cream packaging can also affect its melting rate.

Using packaging materials with excellent insulation properties can effectively slow down the melting rate of ice cream. For example, double-layer packaging, vacuum packaging, or insulated bags are all good choices, as they can prevent external heat from affecting the ice cream and delay its melting.

Creative packaging designs can also provide some insulation. For example, packaging designed with a double-layer structure can form a protective barrier on the outer layer, reducing heat transfer and thus slowing down the melting rate of ice cream.

4. Low-temp storage and transportation

Maintaining a low-temperature environment during storage and transportation is crucial for slowing down the melting of ice cream.

In commercial settings, ice cream is typically stored and transported at freezing temperatures to ensure its freshness and stability. Additionally, using refrigerated vehicles and containers can minimize the impact of external heat during transportation, preserving the freshness and stability of the ice cream.

5. Rapid Consumption or Refreezing

If you find that your ice cream is starting to melt, the best course of action is to consume it quickly or refreeze it.

Rapid consumption can reduce the time ice cream is in contact with external heat, thereby slowing down its melting rate. If you're unable to finish the ice cream immediately, you can return it to the freezer for refreezing to prevent it from completely melting.

In conclusion, although we can employ various methods to slow down the melting rate of ice cream, ice cream is ultimately a kind of food that melts easily. Summer's high temperatures are inevitable. Therefore, when enjoying ice cream, the most important thing is to savor it promptly and fully enjoy its coolness and deliciousness.
