7 Mitacs Globalink (GRI) research projects for Summer 2027.

1. Conflicting nutrition information on social media

This undergraduate research project examines how conflicting nutrition information on social media contributes to confusion about healthy eating. Nutrition misinformation has become widespread in digital environments, where users are frequently exposed to contradictory messages from influencers, commercial actors, and health professionals. These conflicting claims can undermine trust in scientific evidence and make it difficult for consumers to identify credible advice. The objective of this project is to explore how conflicting nutrition messages are presented online and how credibility is communicated. Specifically, the student will identify examples of contradictory claims on a focused topic such as protein intake and analyze how different sources frame their messages. The project aims to build understanding of how individuals may interpret and navigate this fragmented information landscape. The student will collect a small sample of publicly available social media posts from platforms such as Instagram or TikTok. Posts will be selected to include both expert sources, such as registered dietitians or public health organizations, and non-expert influencers. Using a structured coding approach, the student will analyze each post for message content, tone, type of evidence, and indicators of credibility. Posts will then be grouped to identify direct contradictions and patterns in how conflicting claims are communicated. A final reflective analysis will examine how these differences may influence perceptions of trust and understanding. Anticipated results include the identification of clear inconsistencies in nutrition messaging, particularly between evidence-based and influencer content. The project is expected to show that credibility cues vary widely and that conflicting information can create uncertainty about what constitutes healthy eating. This project is significant because it provides hands-on experience in analyzing real-world nutrition communication while contributing to broader efforts to understand and address misinformation in digital food environments.

Research area, student roles & skills

Research area: My research focuses on how digital technologies are transforming the way people interact with food, and what this means for public health. I study digital food environments such as online grocery platforms, food delivery apps, and social media and their influence on food choices, food literacy, and nutrition behaviours. My work also examines how online nutrition information is communicated and understood, including the role of influencers and health professionals. Across projects, I aim to improve health equity by developing inclusive tools and evidence-based strategies that support healthier, accessible, and informed food decisions in a digital world.

Student roles:
The undergraduate student will play an active and integral role in a research project examining conflicting nutrition information on social media. Working under supervision, the student will be responsible for identifying and collecting relevant social media content on an assigned nutrition topic (e.g., #highprotein). They will organize and manage this dataset, ensuring that posts represent a diversity of perspectives, including both expert and non-expert sources.

The student will conduct a structured content analysis using a predefined coding framework. This will involve carefully reviewing each post to identify key messages, types of evidence, tone, and indicators of credibility. They will compare posts to identify contradictions and emerging patterns in how nutrition information is presented. The student will also contribute to interpreting findings, including reflecting on how conflicting messages may influence perceptions of trust and understanding.

In addition to independent work, the student will regularly communicate progress and challenges with the research supervisor and, when applicable, other team members. They will participate in lab meetings, where they will share updates, receive feedback, and engage in discussions about nutrition misinformation, research methods, and knowledge mobilization. These meetings will provide opportunities to build confidence in presenting ideas and contributing to a collaborative research environment.

The student will also be responsible for preparing a final report and a brief presentation summarizing their findings. Throughout the project, they will develop skills in critical thinking, qualitative analysis, organization, and scientific communication, while gaining hands-on experience in research on nutrition misinformation in digital environments.

Skills required:
The ideal student should have foundational knowledge in nutrition, food science, public health, health sciences or related disciplines. Students in anthropology, communications, or media studies will also be considered. Strong communication skills, English language skills, and the ability to work with team members of different backgrounds are required. Strong critical thinking skills are essential to assess credibility, compare conflicting messages, and reflect on potential impacts on consumer understanding. The student should also demonstrate attention to detail, organization, and the ability to work independently. Basic skills in qualitative analysis, such as coding and thematic identification, are an asset.

2. Contrôle des virus d’origine alimentaire par le développement de méthodes d’inactivation

Foodborne illnesses due to the presence of viral pathogens are of major interest for the public health. It is important to detect or inactivate very low levels of viruses found on food to prevent potential outbreaks. Our laboratory is a Canadian reference in food virology and is specialized in developing innovative methods to detect, concentrate or inactivate foodborne viruses. This project will be part of a Research Chair dedicated to the control of foodborne viruses. The main goal of this summer project will be to develop a new viral detection method, or an inactivation method based on a chemical or physical treatment. To easily progress through the project, the trainee will be paired with a Master, PhD, or postdoctoral student. To do so, at risk produces (strawberries, raspberries, oysters) or surfaces (stainless steel) will be artificially contaminated with key foodborne viruses or viral surrogates. The newly developed detection method or the inactivation method will be tested with these contaminated food or surfaces. Molecular biology or cell culture methods could be used to assess the efficiency of the method to detect or inactivate the virus. The results generated during this internship will make it possible to set up better control strategies for viruses of food origin and will contribute to the success of the new VIR.AL Research Chair: Innovative approaches for the assessment and integrated management of risk in food virology of Prof. Julie Jean.

Research area, student roles & skills

Research area: Each year more than 600 million people are affected worldwide by foodborne illnesses. Foodborne viruses are the most incriminated foodborne pathogens. To maintain high food safety and quality, it is important to detect and inactivate these viruses. However, available methods are fastidious, long and may not be adapted to all types of food matrices. To overcome these problems, our research team has one goal, to develop innovative viral detection and inactivation methods to ensure food safety and control for food industries.

Student roles:
Initially, the trainee will be asked to read on his project to acquire the required knowledge.
Secondly, the trainee will be asked to prepare and plan his experiments with the help of his supervisor to successfully achieve all protocols associated with his or her project based on currently used laboratory techniques or newly developed methods.
Finally, the trainee will be asked to collect and analyzed all the data related to his or her summer project.
In parallel to his or her project, the trainee will also be of great technical support to the research team by helping other laboratory teammates with their project.
Take note that vaccination may also be offered if necessary. Furthermore, it is important to note that our food virology laboratory is equipped with all the infrastructure and equipment for safe handling of viruses and is certified biosafety containment level 2 (BSL2).
Lastly, the student will be part of our lab meeting and could also present their work during different local meetings. Upon completion of this summer project, the trainee will also be asked to write a short laboratory report of his work. Finally, data generated by the trainee, could be part of a publication reviewed by peers.

Skills required:
The successful candidate must have a BSc degree (or about to obtain) in microbiology, molecular biology, or other related disciplines. He or she should have practical skills in the microbiology and/or cell biology fields.
The student should also have a special interest for research in food sciences and microbiology. He or she should also have to be independent, organized and can work with a team.
Mastering French (written and spoken) will be considered an advantage.

3. Development of Biodegradable Films from Yellow Pea Starch for Sustainable Food Packaging Applications

Canada is the world's largest producer and exporter of yellow peas, with annual production exceeding 3.5 million tonnes in Manitoba and Saskatchewan. Yellow pea starch constitutes approximately 35 to 45 percent of seed dry weight. Following protein extraction, large quantities of starch remain as a co-product in processing facilities, yet most is sold as low-value animal feed, failing to capture its full economic or environmental potential. The food packaging industry generates roughly 141 million tonnes of plastic waste annually, with flexible films representing a large share. Regulatory pressure and consumer demand are driving interest in biodegradable, plant-based alternatives. Starch-based films are promising due to their biodegradability and renewable origin, but Canadian yellow pea varieties have not yet been studied as film-forming materials. Yellow pea starch has a relatively high amylose content (32 to 40 percent) and a C-type crystallinity pattern, distinguishing it from common sources like corn or cassava and suggesting potentially useful film performance characteristics. This three-month project fills that gap. Phase 1 (Weeks 1 to 6) focuses on starch extraction and characterization. Starch from three Canadian varieties (CDC Meadow, CDC Amarillo, and Earlybird) will be extracted via wet milling, separated by centrifugation, and confirmed at above 95 percent purity. Characterization will include amylose/amylopectin ratio by iodine colorimetry, crystallinity by XRD, gelatinization and glass transition temperatures by DSC, pasting properties by RVA, granule morphology by SEM, and functional group profiling by ATR-FTIR. Phase 2 (Weeks 5 to 12) focuses on film fabrication and testing. Films will be cast from 5 percent starch suspensions with glycerol at three levels (10, 20, or 30 percent) and citric acid at two levels (1 or 3 percent), dried and conditioned before testing. Tensile strength, elongation at break, water vapour permeability, optical transparency, and thermal stability will be measured.

In Phase 2, you will fabricate and test starch films across nine formulation combinations, varying glycerol and citric acid levels, and measure tensile strength, water vapour permeability, optical transparency, and thermal stability. Statistical analysis will use one-way ANOVA with Tukey's HSD. You will maintain detailed laboratory records, comply with safety protocols, and contribute actively to manuscript preparation and scientific reporting.

Skills required:
The ideal student should possess a strong background in food science, biosystems engineering, chemistry, or a related field. Familiarity with starch chemistry, biopolymer materials, or food packaging science would be a strong asset. Experience with laboratory characterization techniques such as DSC, XRD, FTIR, or mechanical testing equipment is desirable. Knowledge of statistical analysis methods, including ANOVA and experimental design, is expected. Proficiency in data analysis using Python, R, or equivalent software is an advantage. Effective verbal and written communication skills and the ability to work collaboratively within an interdisciplinary research team are essential for successful project completion.

4. Physics-informed postharvest digital twin for apple quality prediction

Postharvest losses in apples or berries are strongly influenced by temperature, relative humidity, and airflow variability during cold storage and transport. However, current shelf-life prediction tools rely primarily on empirical correlations and do not explicitly account for heat and mass transfer dynamics within cold-chain systems. This project will develop a physics-informed postharvest digital twin that integrates environmental sensor data with reduced-order thermal and moisture transport models to predict apple or berry quality changes under realistic storage conditions.Research Questions 1. How do spatial and temporal variations in temperature, humidity, and airflow affect apple or berry mass loss and firmness decline during cold storage? 2. Can physics-informed surrogate models accurately predict shelf-life outcomes under variable cooling regimes? 3. Which environmental parameters exert the greatest control on quality degradation? Objectives 1. Quantify relationships between cold storage conditions and physical quality metrics (firmness, mass loss, colour). 2. Develop a reduced-order digital twin integrating heat and moisture transport with data-driven surrogates. Expected Outcomes • A validated physics-informed postharvest digital twin prototype. • Quantitative identification of key cold-chain drivers of quality loss.

6. Scrolling for supper: how digital food retail shapes food literacy

This project is a scoping review that maps existing evidence on food literacy within digital food retail environments. Digital food retail, including online grocery platforms, meal kits, and food delivery apps, is transforming how people access and choose food. At the same time, food literacy, defined as the knowledge, skills, and behaviours needed to plan, select, prepare, and consume food, plays a critical role in shaping dietary practices. Understanding how these two areas intersect is essential to identify opportunities and challenges for supporting healthy eating in digital contexts. The objective is to systematically explore what is known about food literacy in digital food retail environments and to identify key gaps in the literature. Guided by the Joanna Briggs Institute framework for scoping reviews, the project addresses the primary question: what is known about food literacy in digital food retail environments? Secondary questions examine which components of food literacy, types of digital retail platforms, and populations have been studied. A structured, multi-step search strategy will be used, beginning with an initial database search to identify relevant keywords, followed by a comprehensive search across selected databases and a review of reference lists. Eligible studies include peer-reviewed literature focused on any population and examining food literacy within digital food retail contexts. Screening will be conducted using predefined inclusion criteria based on population, concept, and context. Data will be charted using a standardized extraction table that captures study characteristics, methods, and findings. Anticipated results include a descriptive synthesis of the literature, highlighting commonly studied platforms, populations, and dimensions of food literacy, as well as key gaps. This project is significant because it will provide a foundation for future research and interventions aimed at improving food literacy and supporting healthier food choices in increasingly digital food environments.

7. Transfer and inactivation of Cronobacter and Salmonella dry biofilms in infant formula processing

There have been several high profile outbreaks linked to infact formula that can be attributed partly to the high susceptibility of infants to foodborne illness but also challenges in maintaining sanitary standards in processing environments. Infant formula is highly nutritious and can support the growth of a wide range of foodborne pathogens, most notably Cronobacter sakazakii and Salmonella when hydrated. Therefore, to prevent the growth of pathogens attempts are made to maintain low moisture of the product and processing environment. However, when contamination issues are encountered many processors resort to wet sanitation then can lead to pathogen growth and the formation of dry biofilms of pathogens when surfaces are dried. Dry biofilms have enhanced resistance to sanitizers and can persist over extended periods, thereby representing a continuous source of contamination. Consequently, there is a need for a dry sanitation method that can be applied to inactivate pathogens on surfaces without introducing water – essentially a moisture free approach. In the following, dry biofilms will be created of Salmonella and Cronobacter to mimic an infant formula environment. The transfer of pathogens within dry biofilms to infant formula will be evaluated to establish the food safety risk. A second part of the study will assess a range of disinfection methods that will include a hydroxyl-radical process, ultraviolet light, dry steam, alcohol and surfactants. Selected sanitation methods will be optimized to maximize disinfection efficacy. The deliverable of the research will be a moisture-free process that can be applied in low moisture environments to enhance food safety.

Research area, student roles & skills

Research area: Our research area is food microbiology, emphasizing applied food safety. Specifically, we undertake risk assessment, management, and communication with industry, consultants, and regulators. Although we consider all food commodities, most of our focus has been on low-moisture foods, fresh fruit, vegetables, and meat. Here, we determine the sources and interaction of pathogens with foods at the production and processing levels. Once the hazards are identified, we develop interventions (e.g. gas phase hydroxyl-radical process) for control. Risk communication involves preparing Infogrames and guidance documents in collaboration with the United Nations FAO.

Student roles:
The intern will cultivate pathogens and prepare dry biofilms of plastic and stainless steel surfaces. They will then determine the transfer coefficient of pathogens within dry biofilms to infant formula and growth media. The second part will evaluate a range of sanitation methods to eliminate pathogens that are part of dry biofilms. Selected treatments will then be optimized to achieve maximal lethality towards the target pathogens.
Dry biofilms are formed by inoculating the test pathogen onto stainless steel coupons and intermittently misting reconstituted infant formular over a 7 day period. The resultant biofilms are viewed under confocal or SEM to view the cell morphology and arrangement. The cells will be recovered by using recovery media to disperse biofilms then pathogen levels will be enumerated on growth media.
The transfer of pathogens associated with dry biofilms will be determined by overlaying infant formula of the surface of inoculated stainless steel coupons. The infant formula will then be recovered and levels of pathogens enumerated. The variables will be the maturity of biofilm, the relative humidity of the environment and contact time.
The sanitizers to be evaluated for dry biofilm inactivation will be a hydroxyl-radical process based onto applying hydrogen peroxide mist and ultraviolet light. The treatment will be compared with alcohol sanitizers supplemented with surfactants. Trials will also be performed with dry steam. The criteria of success will be to achieve a >5 log CFU reduction of Salmonella and Cronobacter without damaging the stainless steel surface.
The most effective treatment will be taken forward for optimization in terms of reactant concentration, contact time and treatment temperature. The maturity of biofilms and the potential of pathogen post-treatment recovery will also be investigated.

Skills required:
The project is multi-disciplined, involving microbiology, chemistry, and engineering. Yet, the majority of focus will be on the microbiology aspects of the project, although we have the opportunity to gain experience in the chemistry and engineering aspects of the project.
In terms of skill requirements, preference will be given to those with experience in working within a microbiology laboratory and working with pathogens. A background in microbiology, food science, environmental science or biochemistry would be suitable.
