The "ity" factor in hospital meals : Performing, experiencing, and understanding hospitality within the hospital frame
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to explore how the notion of hospitality could be used as a perspective to understand the meal provision within a hospital frame. Of interest was how patients (>65 years of age) experience their mealtimes together with perspectives from the ones serving the meals. This is motivated by older adult patients being more affected by malnutrition and having more challenges during mealtimes than other patient groups. Previous research has identified the importance of assistance during mealtimes and the implications that staff can have for patients’ food intakes. However, few studies have been found that focus on older adult patients’ own experiences of meal provision from a qualitative approach, nor studies that have focused on the practical doings by the staff.The thesis is grounded in an interpretive perspective viewing social reality as constructed and experienced in relation to how one interacts with other subjects as well as objects, by applying the theory of symbolic interactionism together with Goffman’s dramaturgical theory. In addition, the FAMM was used to understand the entirety of the meal experience, and the person-centred care approach to understand the study setting of interest.The fieldwork was conducted across four wards at two Swedish public hospitals, and interviews were conducted at three of these wards. In total, 20 mealtime observations together with 11 interviews with patients and 20 interviews with staff in different categories were conducted. The wards differed in relation to the dining room environment, the role of the meal host and how the meal service was conducted.The overall findings reflect these differences by suggesting that the meal provision needs to be understood as a balancing act, where the staff perform in front of the patients in relation to the hospitability provided by the organisational host. The patients experienced hospitality through being acknowledged and recognised together with unexpected moments of hospitality. In turn, the staff were found to be knowing and caring in their performances towards the patients as well as showing professional knowledge when reading between the lines and offering what not always was voiced.The findings identify a need by the staff to be able to have more time with the patients, having the ability to perform a meal service in a timely manner as well as the ability to navigate within the organisational frames. Demonstrating the need for, as well as the presence of, the “ity” factor in hospital meals.

Att gestalta måltider – mise en place, dukning och servering : En metodstudie i servitörens hantverkskunnande
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- I restaurangbranschen har rationaliseringar tvingats fram och kunskap efterfrågas i mindre omfattning. Syftet med avhandlingen är därför att utveckla begrepp och pröva metoder för att återge och förmedla procedurer och göranden i hantverk för att därigenom visa vad som är servitörens yrkeskunskap. Avhandlingen undersöker metoder som fångar hantverkets sinnliga aspekter genom att synliggöra och vetenskapliggöra den dimensionen av ett hantverk. Den ledande frågan är hur servitörens hantverkskunnande för mise en place, dukning och servering kan visualiseras, kommuniceras och förstås?Olika metoder har prövats och forskningen har skett i och genom hantverk med egen restaurangerfarenhet som utgångspunkt. Film som metod har prövats för att vetenskapliggöra betydelsen av hantverkarens sinnliga bedömningar. Metoder från tidsgeografi, som förklarar det materiellas bundenhet till tid och rum, samt från taxonomi för tredimensionell visuell analys, som ger förståelse för gestaltning, har använts.Resultaten visar att hantverkaren oreflekterat tar stöd av sina egna sinnen för att bli effektivare och säkerställa sitt hantverksutförande. Resultaten visar även att de tidsgeografiska begreppen kapacitets-, kopplings- och auktoritetsrestriktioner möjliggör att identifiera och förklara de hinder som servitören tar hänsyn till vid planering och genomförande av en hantverksprocedur. När kunskap om förklaringar länkas samman med kunskap om förståelse, blir det möjligt att beskriva hur gästen i en måltidssituation kan styras och påverkas av estetiken. Genom ett flermetodologiskt tillvägagångssätt har hantverkskunnandet för procedurerna mise en place, dukning och servering artikulerats vetenskapligt i ord och bilder.

- Using dill (Anethum graveolens L.) as a model herb, we revealnovel associations between metabolite profile and sensory quality, by integrating non-target metabolomics with sensory data. Low night temperatures and exposure to UV-enriched light was used to modulate plant metabolism, thereby improving sensory quality. Plant age is a crucial factor associated with accumulation of dill ether and α-phellandrene, volatile compounds associated with dill flavour. However, sensory analysis showed that neither of these compounds has any strong association with dill taste. Rather, amino acids alanine, phenylalanine, glutamic acid, valine, and leucine increased in samples exposed to eustress and were positively associated with dill and sour taste. Increases in amino acids and organic acids changed the taste from lemon/grass to a more bitter/pungent dill-related taste. Our approach reveals a novel approach to establish links between effects of eustressors on sensory quality, and may be applicable to a broad range of crops.

- Greenhouse horticulture is in its broad definition the production of plant products within, under or sheltered by structures that provide protection against biotic and/or abiotic stress. In greenhouses, horticultural crops can grow protected from infectious agents and adverse weather conditions, allowing off-season, year-round production. However, greenhouse production often comes with a trade-off, which is a skewed light environment with a lack of UV light. In some instances, the blockage of UV by greenhouse glass and plastic covers is beneficial from a commercial perspective, especially on tropical latitudes where plants can often encounter higher UV levels, which may impair plant growth and nutrient absorption (Krause et al. 1999; Verdaguer et al. 2017). On the other hand, reduced UV inside greenhouses may reduce the synthesis of metabolites associated with crop protection against biotic and abiotic stress, such as flavonoids, terpenoids and alkaloids (Yang et al. 2018). This reduction in the amount of protective compounds may not be seen as an important limitation in a protected environment, but these metabolic changes caused by reduced UV exposure may in fact negatively impact on product quality. For example, it is possible to improve of the aroma and taste of greenhouse tomato by exposing plants to low levels of supplementary UV light (Dzakovich et al. 2016).

Tidskriftsartikel (refereegranskat)abstract
- Healthy diet interventions have been shown to improve depressive symptoms, but thereis a need for randomized controlled trials (RCTs) that are double blind and investigate biologicalmechanisms. The primary objectives of this randomized controlled pilot trial were to test thepalatability of the meals and the acceptability of the intervention in preparation for an 8-week RCTin the future, which will investigate whether a healthy Nordic diet improves depressive symptomsin individuals with major depressive disorder, and associated biological mechanisms. Depressed(n = 10) and non-depressed (n = 6) women and men were randomized to receive either a healthyNordic diet (ND) or a control diet (CD) for 8 days. Participants were blinded to their diet allocationand the study hypotheses. Health questionnaires were completed before and after the interventionand, throughout the study, questionnaires assessed participants’ liking for the meals, their sensoryproperties, adherence, and open-ended feedback. In the ND group, 75% of participants consumedonly the provided foods, as instructed, compared to 50% of CD participants. The meals of both diets,on average, received good ratings for liking and sensory properties, though the ND ratings weresomewhat higher. Overall, results were positive and informative, indicating that the planned RCTwill be feasible and well-accepted, with some proposed modifications.

Sensory qualities and culinary utility of produce : a path towards sustainable gastronomy
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The underlying assumption throughout this thesis is that the continuity of a cultivated diversity can be strengthened by investigating its sensory qualities and specifying particular culinary utilities of landraces and cultivars. How can a foodstuff’s sensory qualities and culinary utility be explored, tested, and refined together with the food industry and the public meal? This thesis aims to create a path toward sustainable gastronomy with greater sensory variation that originate from a cultivated diversity. The thesis bridges sensory science, culinary arts, and food design, using sensory descriptive methods with consumers as well as trained sensory panelists, consumer tests with different target groups, and a recipe-development process joined up with culinary arts and agriculture. The thesis is based on four papers. Paper One shows that cultivated diversity generates a range of flavors and textures to advance in food and cooking. Paper Two investigates the interacting influence of cultivar, place of cultivation, and year of harvest on the sensory quality of peas. In Paper Three, a recipe development process is modelled and applied to gray peas, showing how appealing plant-based products can be developed. Finally, Paper Four suggests that unique/novel and natural are promising terms to use for plant-based food products, both of which could be strengthened by elements of artisanal but not vegetarian associations. A cyclic investigation and the inclusive continual improvement of a foodstuff’s sensory qualities and culinary utility with purpose and target is proposed and applied in the culinary funnel model (Paper Three), and culinary action as a tool for multi-sectoral cooperation in Paper Four. Since sensory variation is necessary for gastronomic potential, it would be useful to perceive cultivated diversity as a fundamental quality in any cuisine. Who knows which species and cultivars might be favored in the light of climate change, unsustainable resource consumption, and a growing food demand?
