Co-creation of food solutions to sustain health and autonomy in older adults
Abstract: For older people, eating well is a key factor in preserving their health and preventing the onset of diseases linked to ageing. However, ageing may be accompanied by a decline in appetite and food intake. Several studies have reported nutrient intake lower than recommended levels for older adults, especially protein. In this context, project FORTIPHY will develop new food solutions which allow older people to fortify their regular meals. The aim is to increase protein and, where needed, calorie intake without increasing the volume to be ingested. The innovation potential of this project lies in involving end-users (older people and caregivers) very early in the development of fortified recipes through focus groups and home-usage tests. This will ensure high adoption and compliance levels by the target population. In parallel, the project will evaluate the nutrition efficiency (bioavailability), influence on satiety and acceptability of the fortified foods in order to ensure that they fulfil the nutritional needs as well as the sensory expectations of older consumers.
This work received funding from ANR (ANR-20-HDHL-0003 FORTIPHY), Research Council Norway (RCN 321819), BBSRC (BB/V018329/1) under the umbrella of the European Joint Programming Initiative "A Healthy Diet for a Healthy Life" (JPI HDHL) and the ERA-NET Cofund ERA-HDHL (GA N°696295 of the EU Horizon 2020 Research and Innovation Programme).
Prof Lisa Methven, Department of Food and Nutritional Sciences, University of Reading, UK
Lisa Methven is a Professor of Food and Sensory Science at the University of Reading, UK. Her research focuses on the association between sensory perception of foods and liking, food choice, appetite and dietary intake. Lisa's research group pursue three main research themes. Firstly, the influence of genotypical and phenotypical differences in taste perception and their impact on dietary choice. Secondly, in the arena of product reformulation, her research focuses on understanding and modifying the perception and acceptability of foods designed to improve health. Finally, Lisa's group aim to understand the influence of sensory perception on food choice across the lifespan, from understanding perception in children, to improving the palatability of foods designed to meet the nutritional needs of older people.

Understanding better sensory alterations to provide tailored food solutions for cancer patients
Abstract: Chemotherapy treatments can induce various undesirable effects, including sensory disturbances leading to a change in food preferences that can result in a significant reduction in the pleasure of eating and food intake. The aim of the presented work conducted as part of the PhD thesis of Kenza Drareni is to explore the effect of chemotherapy during cancer on the olfactory and gustatory abilities of patients and the consequences that this may have on their eating behaviour. The first part of this work focuses on understanding the variability of sensory changes and their consequences on patients' eating behaviour. Our results highlighted three main sensory profiles: patients with no sensory impairment, patients with hyposensitivity, and patients with hypersensitivity to olfactory/gustatory stimuli. Patients with impaired olfactory/gustatory abilities also expressed changes in their food behaviour. The classification of patients based on their self-reported sensory abilities highlighted the negative impact of hyposensitivity on food taste perception. The classification based on a psychophysical assessment of olfactory abilities showed a change in consumption habits in patients with hyposmia. Both approaches found a general downward trend in perceptual abilities of cancer patients treated with chemotherapy. In the second part of this work, we examined the effect of food sensory enhancement as a coping strategy to sensory alterations. The results suggest that taste or aroma enhancement increases food liking in patients with decreased olfactory/ taste sensitivity and patients who did not report taste and smell deficits, but it has no effect on the hedonic rating of food in the group of control subjects. This work highlights the inter-individual diversity existing between patients and confirms the involvement of olfactory/taste alterations in patients' food behaviour modification. Our results stress the importance of personalized nutritional management of patients considering their sensory alteration profile.

Oncofood project: new food solutions for cancer patients
Abstract: One of the main challenges for cancer patients undergoing treatment in preventing or mitigating malnutrition. It is known that close to 70% of patients undergoing treatments experience side effects (taste loss, bad taste in mouth, metallic taste, saliva absence, vomiting, loss of appetite) that may have a large impact on their daily food intake. The current clinical nutrition market offers different oral nutritional support products. However, they do not address the pleasure of eating nor patients' food preferences. The aim of the Oncofood project was to design and develop new innovative food solutions addressed to cancer patients considering not only their nutritional requirements but also their sensory alterations, promoting the pleasure of eating and preventing malnutrition. A range of soup and mousses in pouch packs were developed for patients with taste and smell alterations while a number of 3D printed meals were created for patients experiencing swallowing difficulties. Products were evaluated by patients across three countries (Spain, Poland and UK) with results showing that the mousses were the most preferred product in all countries. Overall, participants preferred the 3D printed meals to normal puree and considered them safe and natural. However, they were unsure how useful a 3D food printer would be for home use.
This project received funding from EIT Food (innovation project - grant agreement number: 20139).

Olfactory dysfunction post-COVID-19 – and how to measure it
Abstract: Olfactory disorders are fairly common, occurring in up to 20% of the general and until recently, were often unrecognised and under-researched. The COVID-19 pandemic has certainly raised general awareness and moved olfactory dysfunction up the research agenda. Sudden onset of anosmia occurs in up to half of all cases of COVID-19 (dependent on variant) of which about 20% of cases may go on to experience long term olfactory dysfunction. Recovery from long term smell loss often begins with parosmia, a condition where smells become distorted and objectionable, with those severely affected rejecting food, losing weight, leading to clinical depression. Such changes in a significant proportion of the population can have an impact on the performance of sensory and consumer panels, particularly as recent research has demonstrated that self-reporting of olfactory function is unreliable. In the lecture, we will focus on recent research on the characterisation and mechanisms of olfactory disorders, and touch on their impact on quality of life. In the workshop, you will be able to try out different tests of olfactory function (Sniffin’ sticks, UPSIT, SNOT-22) and discuss their individual merits.
Dr Jane Parker, Department of Food and Nutritional Sciences, University of Reading, UK

She founded the Flavour Centre (the University’s interface between flavour research and the food industry) and is currently lead for the department’s Food Research Group. Her expertise is in flavour analysis, GC-Olfactometry, flavour formation pathways and flavour interactions, however, over the past 3 years, she has developed an interest in olfactory disorders, particularly parosmia, which have come to the fore during the Covid-19 pandemic.
Creating Delicious Plant-Based Products – The Sensory Perspective
Abstract: The recent exponential increase in interest in vegan food is not only due to the rise in people following a vegan diet but also in those increasing the amount of plant-based food in their diet. This means there is a unique opportunity in a rapidly expanding market, but food manufacturers need to be aware of who they are designing and developing products for. There may be a difference in desired product attributes between consumers switching between animal-based products and their plant-based alternatives and those who have given up eating animal-derived products many years ago.
As Sensory and Consumer Scientists, we should also be aware that this may affect the test objectives and setup. As ever, it's important to keep in mind the objectives of the evaluation and design the test accordingly. For example, does the product need to be assessed hot or cold? Does the appearance have an impact? And should it be evaluated alone or with typical accompaniments? The impact of different aspects, including formulation, of both dairy and meat alternatives will be discussed.
