Nanobubble and polyphenol technology for improved ice cream quality

Overview

This research proposes a novel approach to improving ice cream quality by incorporating air-infused nanobubbles during processing and adding polyphenol ingredients derived from fruit sources. The combined approach aims to reduce ice crystal size, decrease melting rates, and enhance resistance to temperature fluctuations during transportation. Nanobubbles generate nucleation points that produce nano-sized ice crystals with high surface areas, while polyphenols contribute additional structural benefits. Together, these innovations address common challenges in ice cream quality related to texture, shelf life, and thermal stability.

Technical specifications

Key features:

• Air-infused nanobubbles introduced during ice cream processing create nucleation sites for smaller ice crystal formation
• Polyphenol ingredients from fruit sources serve as food-safe additives that further reduce melting
• Smaller ice crystals produce higher surface area, enabling faster and more uniform cooling
• Nano-sized crystals form a more homogeneous structure that resists separation and maintains texture
• The technology builds on validated nanobubble slurry applications previously tested for fish preservation during transportation

How it works:

Nanobubbles possess properties including neutral buoyancy and a small negative charge, allowing them to remain suspended in liquid and serve as nucleation points during freezing. When ice cream is processed with these nanobubbles, the resulting ice crystals are significantly smaller than those formed through conventional methods. The increased surface area of these nano-crystals improves thermal conductivity and cooling performance. Polyphenols complement this effect by interacting with the ice cream matrix to further stabilize the structure and slow melting.

Technology readiness level

The technology is currently at an early-to-mid stage of development. Prior validation has demonstrated that nitrogenated nanobubble-infused ice slurries reduce food spoilage and improve cooling rates compared to traditional ice in fish transportation applications. Future validation will involve formulating nanobubble-infused ice creams with and without polyphenol coatings, conducting microscopy analysis with cooling and heating stages to evaluate microstructures, performing sensory profile testing, and optimizing formulations for scalability. The proposed study is expected to be completed in less than six months.
