Scientists have developed methods to prevent ice cream from melting during hot weather conditions. Japanese manufacturer Kanazawa Ice achieved this breakthrough by adding polyphenols, which are antioxidant molecules found in various fruits. Food scientist Cameron Wicks from the University of Wisconsin investigated how these compounds create stability in frozen desserts. Her research focused on tannic acid, a specific type of polyphenol that interacts with cream proteins. The molecules form protective networks around fat globules, preventing them from merging when ice crystals melt.
Wicks conducted experiments using different concentrations of tannic acid in cream mixtures. Higher concentrations produced thicker substances that could maintain their shape even when warmed. The treated ice cream develops a pudding-like consistency over time while retaining its original form. However, polyphenols cannot maintain cold temperatures; only maintain structural integrity. Food manufacturers may adopt this technology to improve product stability during transportation and storage.
