Background

Developing high-quality ice cream requires a delicate balance between processing parameters, ingredient formulation, and sensory experience. General Mills is looking to leverage AI and ML-driven modeling approaches to optimize ice cream processing and formulation while ensuring that the final product maintains its expected sensory properties. 

 

Achieving an optimal balance between texture, mouthfeel, and stability while maintaining production efficiency is challenging due to the inherent variability in ingredients and processing conditions. Current methods rely on time-intensive physical experimentation, making it difficult to predict how formulation and process adjustments will impact the final product. 

 

To address this challenge, we seek hybrid simulation models (combining multiphysics and ML-based predictions), AI-powered ingredient interaction modeling, and consumer sensory experience prediction to develop a digital framework that links process parameters, ingredient composition, and end-product perception. 

 

A robust AI-driven system will enable rapid scenario testing, significantly reducing the time and cost associated with traditional R&D. By predicting the effects of changes in freezing conditions, mixing speeds, stabilizer concentrations, or ingredient substitutions, this approach will enhance production agility, improve product quality, and accelerate innovation. Ultimately, this will ensure that any changes in formulation or processing result in a final product that meets both manufacturing efficiency goals and consumer expectations.

What we're looking for

We are looking for innovative AI- and ML-driven approaches to improve ice cream processing and formulation. We are open to solutions that incorporate hybrid simulation, ingredient interaction modeling, and sensory prediction. Ultimately, we seek to integrate these models into a cohesive framework that accelerates innovation while ensuring product quality, efficiency, and consistency.

Solutions of interest include:
  • AI driven ingredient interaction modeling to predict texture and stability
  • Hybrid simulation framework using multiphysics modeling and machine learning
  • Consumer sensory prediction model trained on preference and sensory data
  • Digital twin of the manufacturing process to simulate and test production scenarios
Our must-have requirements are:
  • Leverages AI or machine learning to improve ice cream formulation or processing
  • Adaptable to different manufacturing conditions and ingredient formulations
  • Includes consumer sensory prediction to forecast taste and texture preferences
Our nice-to-have's are:
  • Predicts ingredient interactions and product properties
  • Proposals that outline data needs and/or propose methods for acquiring or supplementing data
Acceptable technology readiness levels (TRL):
Levels 6-9

Q.
We are a research group of the University of Padua, made up of professors and PhD students who have been working on innovative technologies in the production of artisanal gelato, a typical Italian product, and industrial gelato for a long time. We are experts in food technology, food chemistry, rheology and sensory analysis; we also have experience in AI. I would like to know if these skills can be useful to present a project in accordance with your requests.

Q.
We use Large Language Models to optimize recipe ingredients for health, sustainability, and taste. Ice cream is next—we have 75 recipes, 431 reviews, tools, and a plan. No sensory tests yet. Does this meet TRL 6?
1
A.
Yes, it could be relevant. We welcome you to submit your proposal and we can assess further for a fit. Would you expect General Mills to provide the data for the LLM, or would you be also providing data? Further, do you have any published materials or other examples we might reference on another food product (to better understand the approach).

Q.
Dear Team Halo Together with the research group, we are discussing the contents of the project on ice cream and AI. I did not understand if you want to start from data already published on ice cream ingredients and sensory response. Alternatively, my research group proposes a series of ice cream formulations, analyzes them from a chemical-physical and sensorial point of view (Analytical panel test and Consumer test), creating models and interfacing with AI. I would like to understand what General Mills wants to start from (existing data or new formulations made in the "Food grade" laboratory). In any case, the research group of the University of Padua has the skills you requested and we have been working on ice cream for a long time. Thank you Giovanna Lomolino and the research group

Thank you for this great question. We would certainly be interested to see the results of your approach being successfully tested on your own data. We would anticipate eventually providing a partner with General Mills' data as part of the partnership. But it would favorably differentiate your proposal if there were a successful MVP/prototype with your own data.
