Innovation in Traditional Food Products

2016

International audience; Innovation is widely accepted as one of the keys to being successful. However, companies can innovate and still fail if markets fail to accept the innovation. In most cases, the acceptance of an innovation depends on the innovation itself and also on the product to which it is applied. In this chapter acceptance of different innovations in traditional food products is investigated, thus focusing on the definition of the "traditional" and "innovation" concepts from the consumer's perspective. Qualitative and quantitative approaches are combined to better understand and predict the possibilities of success when applying different generic and specific innovations in tra…

Impact of food fortification on nutritional outcomes and satisfaction in the older people: A systematic literature review protocol

2021

Malnutrition, a recognized pathology in the older adults, corresponds to an imbalance of nutritional intake compared to the body's needs. To treat this disease, several alternatives can be used, among which there is food fortification. Food-based fortification (also known as dietary enrichment) corresponds to the addition of conventional foods or high calorie and/or nutrients ingredients in the person's meals and dishes. It is a strategy used to treat moderate and severe malnutrition but can be employed as prevention. In this context, the purpose of the present study was to conduct a systematic review of all studies related to the nutritional and satisfaction issue of fortified foods dedica…

En EHPAD, repérer les petits mangeurs et adapter leur alimentation : quel coût, quel bénéfice ?

2018

National audience; Des pesées alimentaires ont montré qu'une large majorité de personnes âgées vivant en EHPAD (Etablissement d'Hébergement pour Personne Âgée Dépendante) ne mange pas suffisamment pour couvrir ses besoins nutritionnels. Il s'ensuit un coût pour les personnes elles-mêmes (augmentation du risque nutritionnel), ainsi qu'un coût pour l'environnement (gaspillage alimentaire). Dans ce contexte, l'objectif de RENESSENS était de proposer aux résidents d'EHPAD une offre alimentaire adaptée à leurs capacités d'ingestion afin de couvrir leurs besoins nutritionnels. Pour cela, nous avons réalisé une étude clinique de 6 mois dans deux maisons de retraite, l'une contrôle (n=43) et l'autr…

Smelling in the old age

2017

Several authors argued that ageing is accompanied by an impairment of olfactory abilities, i.e., the ability to perceive an odour or a taste. However, beyond this overall effect of age on chemosensory abilities, ageing is accompanied by variability in olfactory performance: the decline of odour perception with age is not uniform across odorants neither across elderly individuals. Decline in odour perception may not be inevitable to the aging individual and that factors secondary to aging, such as poor health status or cognitive decline, may contribute to deficits in odour detectability beyond the age effect per se.

Culture and odor categorization : agreement between cultures depends upon the odors

2003

This study evaluated the effect of culture on the relationship between psychological dimensions underlying odor perception and odor categorization. In a first experiment, French, Vietnamese and American participants rated several perceptual dimensions of everyday odorants, and sorted these odorants on the basis of their similarity. Results showed that the three groups of participants differed in their perceptual judgments but agreed in categorizing the odors into four consensual groups (floral, sweet, bad, and nature). Three dimensions––pleasantness, edibility, cosmetic acceptability––discriminated these groups in the same way in the three countries. In a second experiment, the participants…

The effectiveness of personalized design to feed elderly people

2015

Beyond the physiological age, the elderly population is characterized by a high heterogeneity in terms of physical, psychological and sociological status (Maître et al, 2015). Regarding eating behavior, several studies have highlighted a large inter-individual variability in chemosensory abilities (i.e. the ability to perceive an odor or a taste; Sulmont-Rossé et al, 2015) and oral-heath status (i.e. dental status, salivary flow; ALIMASSENS project), as well as inter-individual variability in food preference and food intake (AUPALESENS project). However, the food offer dedicated to the elderly population, and in particular to elderly people who needs help to obtain and/or prepare food for t…

Alliesthesia is greater for odors of fatty foods than of non-fat foods

2011

International audience; Alliesthesia is the modulation of the rewarding value of a stimulus according to the internal state (hungry or satiated). This study aimed to evaluate this phenomenon as a function of the nature of the stimulus (odors evoking edible and non-edible items, and the food odors evoking fatty and non-fat foods) and to compare the effectiveness of two reward evaluations (measures of pleasantness and appetence) to reveal alliesthesia. The results showed that both fatty and non-fat food odors were judged as less pleasant and less appetent when the subjects were satiated than when they were hungry, whereas no such difference was observed for non-food odors. There was a greater…

International audience; Texture–taste, texture–aroma and aroma–taste interactions were examined in custard desserts varying in viscosity (at identical composition), sucrose level and aroma nature. All reciprocal interactions were investigated, with each binary interaction addressed through an independent sensory study. Rheological, in vivo aroma release and sucrose release measurements were run in parallel to control for a possible physico-chemical origin of these interactions. Observed interactions were found to be dependent upon the nature of the sensory modalities involved; physico-chemical mechanisms could only in some instances entirely explain these interactions.

International audience; In humans, oral food intake is the ultimate stage of food supply chain and the beginning of food disintegration and digestion process. During aging, the oral health changes and sometimes eating food can be a real challenge as food can be hard to masticate, humidify or swallow. To meet this challenge, and as part of the AlimaSSenS project, a team of researchers from the Centre of taste and eating behaviour investigated the concept of “oral comfort” when eating a food in an elderly population. A group of 107 seniors aged 65 years and more participated in qualitative (focus group) and quantitative studies (tasting sessions) in order to explore the concept of oral comfor…

Improving meal context in nursing homes. Impact of four strategies on food intake and meal pleasure

2014

In France, in most nursing homes, the composition of menus, the time and the place at which meals are served, the choice of one's place at the table are imposed on residents. Yet, the act of eating cannot be restricted to nutritional and sensory aspects alone. It also includes a psycho-affective dimension, which relates to the context in which the meal is served. We tested the impact of four contextual factors, considered individually, on food intake and meal pleasure in elderly people living in nursing homes: the way the main course was named on the menu, the size and the variety of portions of vegetables served to residents, the presence or not of condiments in the middle of the table and…

Providing choice and/or variety during a meal: Impact on vegetable liking and intake

2016

Food choice is defined as providing the opportunity for an individual to select the food he or she wants to consume while food variety is defined as providing an individual with foods that differ on at least one sensory characteristic. Literature shows that providing food choice or providing food variety may increase meal enjoyment and food intake. However, these two factors have been mainly investigated separately, while they may actually co-occur in real-life settings. In fact, in many out-of-home catering situations, individuals have the possibility to choose as many dishes as they desire from among different proposals for their meal. The aim of the present study was to assess the impact…

Techniques culinaires et confort en bouche chez la personne âgée

Culinary processes and food comfortability in an older population Aging is often accompanied by oral impairments, including the loss of teeth and a decline in saliva flow. These changes can lead older people to avoid the consumption of foods that are difficult to chew such as meat. This may consequently increase the risk of sarcopenia (loss of muscle mass, strength and performance) as well as the risk of protein-energy undernutrition in this population. In order to compensate the decline in oral health observed in older individual and to maintain meat consumption, we assessed the impact of four culinary processes (cooking bag, tenderizer, marinade and low-temperature cooking) on the percept…

When a person shows a decline in appetite or loses weight, is essential to adapt his/her diet in order to fulfil the nutritionc needs and prevent undernutrition. Three axes must but considered and combined: enriching diet (increasing the content of essential nutrients in a meal without increasing! the volume to be ingested); adapting food texture to orc capacities (chewing, salivation, swallowing); optimizing food sensory characteristics by taking into account food habit and food preferences.

Le petit mangeur âgé : quand l'appétit fragilise le statut nutritionnel

2018

National audience; Le vieillissement est associé à de nombreux changements physiologiques, sensoriels, psychologiques et sociologiques susceptibles d'avoir un impact délétère sur la prise alimentaire de la personne âgée. Dans le cadre de RENESSENS, 68 personnes âgées vivant en institution (66 à 100 ans ; 87,4±0.9 d'âge moyen ; 75% de femmes) ont été recrutées et suivies pendant 24 heures de façon à peser tous les aliments et toutes les boissons consommées. Les résultats ont montré que 83% des résidents ne satisfaisaient pas à leurs besoins caloriques et protidiques (43% présentaient un apport inférieur au 2/3 des apports conseillés), essentiellement à cause d'une consommation insuffisante d…

Impact d’un amorçage olfactif sur la prise alimentaire auprès de patients Alzheimer

2013

Dans le contexte d’une population vieillissante, la dénutrition chez les personnes âgées est devenue une préoccupation majeure de santé publique, en France comme dans la plupart des pays occidentaux (PNNS, 2011). La dénutrition correspond à un déficit des apports nutritionnels, en termes de calories et/ou de nutriments et micronutriments. Sans prise en charge, elle entraîne une diminution de la mobilité, un risque accru de chutes ou de fractures, une vulnérabilité vis-à-vis des maladies infectieuses et une aggravation des maladies chroniques. En parallèle des stratégies « nutritionnelles » (conseils nutritionnels, utilisation de compléments nutritionnels), l’objectif du programme AUPALESENS…

Monotonous consumption of fibre-enriched bread at breakfast increases satiety and influences subsequent food intake

2012

Research report; International audience; This study aimed to observe the influence of the monotonous consumption of two types of fibre-enriched bread at breakfast on hedonic liking for the bread, subsequent hunger and energy intake. Two groups of unrestrained normal weight participants were given either white sandwich bread (WS) or multigrain sandwich bread (MG) at breakfast (the sensory properties of the WS were more similar to the usual bread eaten by the participants than those of the MG). In each group, two 15-day cross-over conditions were set up. During the experimental condition the usual breakfast of each participant was replaced by an isocaloric portion of plain bread (WS or MG). D…

The role of novelty detection in food memory

2010

International audience; Memory plays a central role in food choice. Recent studies focusing on food memory in everyday eating and drinking behaviour used a paradigm based on incidental learning of target foods and unexpected memory testing, demanding recognition of the target among distractors, which deviate slightly from the target. Results question the traditional view of memory as reactivation of previous experiences. Comparison of data from several experiments shows that in incidentally learned memory, distractors are rejected, while original targets are not recognised better than by chance guessing. Food memory is tuned at detecting novelty and change, rather than at recognising a prev…

ENGAGE: Development of actions to (re)engage institutionalized older people in the meals

2020

Eating in nursing home implies a redefinition of the meal, from the point of view of the nursing staff which are subjected to specific constraints connected to hygiene and nutritional frame, but also from the point of view of the residents who are subjected to the medicalization of food consumption, to the changes of practices and to the redefining of the commensality. In their survey carried out in nursing homes with in-house kitchen, the sociologist P. Cardon and the anthropologist E. Souternon observed that the institution’s kitchen was often perceived as a “black-box” by the residents.A first step of the project consisted in carrying out semi-directive interviews with older people livin…
