Replacing fat and sugar with inulin in cakes: bubble size distribution, physical and sensory properties

The replacement of fat and sugar in cakes is a challenge as they have an important effect on the structural and sensory properties. Moreover, there is the possibility to incorporate an additional value using novel replacers. In this work, inulin and oligofructose were used as fat and sugar replacers, respectively. Different combinations of replacement levels were investigated: fat replacement (0 and 50 %) and sugar replacement (0, 20, 30, 40 and 50 %). Simulated microbaking was carried out to study bubble size distribution during baking. Batter viscosity and weight loss during baking were also analysed. Cake characteristics were studied in terms of cell crumb structure, height, texture and sensory properties. Fat and sugar replacement gave place to batters with low apparent viscosity values. During heating, bubbles underwent a marked expansion in replaced cakes if compared to the control cake. The low batter stability in fat-replaced samples increased bubble movement, giving place to cakes with bigger cells and less height than the control. Sugar-replaced samples had smaller and fewer cells and lower height than the control. Moreover, sugar replacement decreased hardness and cohesiveness and in- creased springiness, which could be related with a denser crumb and an easily crumbled product. Regarding the sensory analysis, a replacement up to 50 % of fat and 30 % of sugar, separately and simultaneously, did not change remarkably the overall acceptability of the cakes. However, the sponginess and the sweetness could be improved in all the replaced cakes, according to the Just About Right scales.

Should healthy eating programmes incorporate interaction with foods in different sensory modalities? A review of the evidence

Commercial interventions seeking to promote fruit and vegetable consumption by encouraging preschool- and school-aged children to engage with foods with ‘all their senses’ are increasing in number. We review the efficacy of such sensory interaction programmes and consider the components of these that are likely to encourage food acceptance. Repeated exposure to a food's flavour has robust empirical support in terms of its potential to increase food intake. However, children are naturally reluctant to taste new or disliked foods, and parents often struggle to provide sufficient taste opportunities for these foods to be adopted into the child's diet. We therefore explore whether prior exposure to a new food's non-taste sensory properties, such as its smell, sound, appearance or texture, might facilitate the food's introduction into the child's diet, by providing the child with an opportunity to become partially familiar with the food without invoking the distress associated with tasting it. We review the literature pertaining to the benefits associated with exposure to foods through each of the five sensory modalities in turn. We conclude by calling for further research into the potential for familiarisation with the visual, olfactory, somaesthetic and auditory properties of foods to enhance children's willingness to consume a variety of fruits and vegetables.

Post-conflict recovery and peacebuilding

Civil wars are the most common type of large scale violent conflict. They are long, brutal and continue to harm societies long after the shooting stops. Post-conflict countries face extraordinary challenges with respect to development and security. In this paper we examine how countries can recover economically from these devastating conflicts and how international interventions can help to build lasting peace. We revisit the aid and growth debate and confirm that aid does not increase growth in general. However, we find that countries experience increased growth after the end of the war and that aid helps to make the most of this peace dividend. However, aid is only growth enhancing when the violence has stopped, in violent post-war societies aid has no growth enhancing effect. We also find that good governance is robustly correlated with growth, however we cannot confirm that aid increases growth conditional on good policies. We examine various aspects of aid and governance by disaggregating the aid and governance variables. Our analysis does not provide a clear picture of which types of aid and policy should be prioritized. We find little evidence for a growth enhancing effect of UN missions and suggest that case studies may provide better insight into the relationship between security guarantees and economic stabilization.

Multi-sensory treatment for children with developmental motor speech disorders

What this paper adds? What is already known on the subject? Multi-sensory treatment approaches have been shown to impact outcome measures positively, such as accuracy of speech movement patterns and speech intelligibility in adults with motor speech disorders, as well as in children with apraxia of speech, autism and cerebral palsy. However, there has been no empirical study using multi-sensory treatment for children with speech sound disorders (SSDs) who demonstrate motor control issues in the jaw and orofacial structures (e.g. jaw sliding, jaw over extension, inadequate lip rounding/retraction and decreased integration of speech movements). What this paper adds? Findings from this study indicate that, for speech production disorders where both the planning and production of spatiotemporal parameters of movement sequences for speech are disrupted, multi-sensory treatment programmes that integrate auditory, visual and tactile–kinesthetic information improve auditory and visual accuracy of speech production. The training (practised in treatment) and test words (not practised in treatment) both demonstrated positive change in most participants, indicating generalization of target features to untrained words. It is inferred that treatment that focuses on integrating multi-sensory information and normalizing parameters of speech movements is an effective method for treating children with SSDs who demonstrate speech motor control issues.

Sensory and consumer science methods used with older adults: a review of current methods and recommendations for the future

Capturing the sensory perception and preferences of older adults, whether healthy or with particular disease states, poses major methodological challenges for the sensory community. Currently a vastly under researched area, it is at the same time a vital area of research as alterations in sensory perception can affect daily dietary food choices, intake, health and wellbeing. Tailored sensory methods are needed that take into account the challenges of working with such populations including poor access leading to low patient numbers (study power), cognitive abilities, use of medications, clinical treatments and context (hospitals and care homes). The objective of this paper was to review current analytical and affective sensory methodologies used with different cohorts of healthy and frail older adults, with focus on food preference and liking. We particularly drew attention to studies concerning general ageing as well as to those considering age-related diseases that have an emphasis on malnutrition and weight loss. Pubmed and Web of Science databases were searched to 2014 for relevant articles in English. From this search 75 papers concerning sensory acuity, 41 regarding perceived intensity and 73 relating to hedonic measures were reviewed. Simpler testing methods, such as directional forced choice tests and paired preference tests need to be further explored to determine whether they lead to more reliable results and better inter-cohort comparisons. Finally, sensory quality and related quality of life for older adults suffering from dementia must be included and not ignored in our future actions.

Protections for persons deprived of their liberty in international armed conflict

This contribution is about the protection of detained persons in international armed conflict. In particular, it compares how the relationship between IHL and IHRL is understood depending on whether one is speaking of the substantive or the procedural rules of protection for detainees. It will be suggested that, whereas the relationship between IHL and IHRL raises fewer problems when speaking of substantive rules, the situation is very different when speaking of procedural rules.

Interactive sensory objects for and by people with learning disabilities

This project engages people with learning disabilities to participate as co-researchers and explore museum interpretation through multisensory workshops using microcontrollers and sensors to enable alternative interactive visitor experiences in museums and heritage sites. This article describes how the project brings together artists, engineers, and experts in multimedia advocacy, as well as people with learning disabilities in the co-design of interactive multisensory objects that replicate or respond to objects of cultural significance in our national collections. Through a series of staged multi-sensory art and electronics workshops, people with learning disabilities explore how the different senses could be utilised to augment existing artefacts or create entirely new ones. The co-researchers employ multimedia advocacy tools to reflect on and to communicate their experiences and findings.
