    When you eat a traditional ice cream in summer, you need to finish it quickly to make sure the treat doesn’t end up melting down your hand. Reach for an ice cream sandwich instead, and you’ll, find the ice cream stays solid longer magically. An ice cream that refuses to melt seems unnatural, but you might be surprised by what’s really behind its practically heatproof (耐热的) abilities.

Ice cream without a proper container in the fridge would lead to ice blocks because of its water content. Most ice cream contains some elements called emulsifiers (乳化剂) that can keep water to fat to prevent ice blocks. They go a step further by helping to keep ice cream consistent, even under the hot sun. On an element list, you might find different chemicals with the same goal: to hold water in so the ice cream doesn’t melt quickly. Ice cream sandwiches generally contain more of those chemicals including emulsifiers than hand-made ones.

If you’re worried about some additives (添加剂) in ice cream sandwiches f which might belong in a lab rather than your kitchen, then you’d better be at ease. Even completely natural elements, which come from beans, might make you stop eating if you’ve heard about their misuse in weight-loss efforts.

Of course, the Food and Drug Administration (FDA) takes any of the side effects of those chemicals into account, and the amount you’d find in an ice cream sandwich isn’t enough to cause health problems. While you meet someone willing to share his ice cream sandwiches with your kid, there’s no reason to fear your kid’s health safety. A slow melt rate method causes you less worry.
