==Conclusion==

It is impossible to imagine ice cream without freezers or refrigeration of some sort; however, the origin of ice cream is much more ancient, going back thousands of year to the ancient Near East and China. Because ice was not easily obtained or made, ice cream was considered food for royalty or upper elites who can obtain ice, particularly in warm seasons. Improvement in ice houses, and general technology development in the 19th century, led to the development of ice cream being more spread. With refrigeration, however, ice cream could now be created without having ice on hand, leading to the eventual widespread presence of ice cream. Key developments of emulsifiers, thickeners, and mixing technologies have also led to the texture that we are accustomed to.
