Researchers in Turkey have found that the way frozen foods are thawed can be just as critical to food quality and safety as the freezing process itself. A comprehensive review—ranked the most read paper of 2025 in IFT’s peer-reviewed journal Comprehensive Reviews in Food Science and Food Safety—analyzed traditional and emerging thawing methods to identify strategies that better preserve texture, nutrients, and sensory quality.

The review explains that thawing is typically slower than freezing, creating opportunities for microbial growth, moisture loss, and chemical changes that degrade product quality. Innovative technologies—including high-pressure, microwave-assisted, ohmic, ultrasound-assisted, pulsed electric field, and radio-frequency thawing—were found to reduce thawing time and improve temperature uniformity.

Importantly, the researchers show that no single method fits all foods. Optimal thawing strategies depend on product type, from meats and seafood to fruits, vegetables, and bakery items, underscoring the need for product-specific thawing solutions in the frozen food industry.
