Special Issue Information

Dear Colleagues,

Freezing is a widely used preservation process both in the food industry and households. During freezing, water is converted into ice crystals, and the water activity of the food system decreases due to the reduction of the available liquid water. Although freezing causes limited deterioration of the original color, flavor, texture or nutritional values in comparison with thermal processing, food materials are prone to being subjected to irreversible tissue damage due to the solute-concentration damage, dehydration damage, and mechanical damage from ice crystals. Control of ice crystal size has been a challenging key point for minimizing freeze damage. Several novel freezing techniques have been attracting remarkable attention and gaining momentum not only within the scientific community but also in the food industry due to their potential to enhance the formation of small size ice crystals and to prevent food products from freeze damage.

This Special Issue will present an overview of the latest applications of novel and innovative freezing technologies applied to food. We would like to invite authors to submit their latest achievements with cutting-edge original research papers or comprehensive review papers discussing novel freezing technologies from the perspectives of water crystallization control, food quality attributes, food safety, sustainability, equipment innovation, freezing process engineering, and consumer acceptance.

This study deals with the mathematical modeling of crystallization kinetics occurring during batch production of the ice cream. The temperature decrease was recorded in-situ through a computerized wireless system. A robust pattern-recognition algorithm of the experimental cooling curves was developed to determine the initial freezing point. The theoretical freezing point was used to calibrate the whole time-temperature profile. Finally, a modified Gompertz’s function was used to describe the main steps of crystallization kinetics. Derivative analysis of the Gompertz’s function allowed to determine the time-temperature physical markers of dynamic nucleation, ice crystal growth and air whipping. Composition and freezing properties were used as input variables in multivariate analysis to classification purposes of the ice cream mixtures as a function of their ability to produce high-quality ice cream. The numerical analysis of the whole cooling curve was used to build predictive models of the ice cream quality indices. Full article
