Abstract
The transition from primary to permanent dentition is an important phase in children's oral development, yet its impact on texture perception and food acceptance are less explored. This study aimed to investigate how changing dentition and tooth loss influence texture preferences and perception of eating difficulty among children aged 5 to 12 years. Children (n = 475) completed a forced-choice questionnaire featuring drawings of six food pairs, each available in hard or soft texture, and reported whether they had started losing primary teeth and the number of tooth gaps present. They also tasted four samples: chocolate snacks (cake and biscuits) and cheddar cheese (grated and cubes), evaluating their perceived eating difficulty and liking for each sample. Analysis of questionnaire responses showed a general preference for softer food textures among children, with a 36% probability of choosing hard foods. Preferences were not related to child's dental state, including primary teeth loss (p = .13) or number of tooth gaps (p = .45). In the taste test, chocolate biscuits and cheese cubes were perceived as significantly more difficult to eat than chocolate cake and grated cheese, respectively (both p < .0001). Children with more than two tooth gaps reported greater eating difficulty for chocolate biscuits and cheese cubes compared to children with fewer or no tooth gaps. This study demonstrated that children's texture preferences for hardness of foods remained consistent during dentition change, while their perception of eating difficulty could vary based on their dental state at specific points in time.

Galler M, Varela P. Methodological approaches to assess tactile sensitivity in the food context-A scoping review. J Texture Stud 2023. [PMID: 38014904 DOI: 10.1111/jtxs.12813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 10/12/2023] [Accepted: 10/30/2023] [Indexed: 11/29/2023]
Abstract
In contrast to taste sensitivity, the assessment of texture or tactile sensitivity has received relatively little attention in the food context. Texture plays an important role in food preferences and food intake, and individual differences make it important to understand physiological drivers of perception as tactile sensitivity. The multi-dimensional and dynamic aspects of texture perception suggest there is not one single method that can explain individual differences. This scoping review aims to systematically map methods assessing tactile sensitivity, in the context of food, highlighting differences in approach and implementation. Eligibility criteria included papers describing methods to assess individual differences in tactile sensitivity, that involved human participants and the context was relevant to food behavior. Sources are peer-reviewed publications of original research in English. In mapping the methods, we assessed how they relate to food texture parameters (mechanical, geometrical, and surface) and the dynamics of breaking down (touch with hand, first bite/sip, oral processing, residual or after-swallowing sensations). We also review other parameters associated (oral processing, preference, diet and food intake behavior). The literature in this relatively young area is still very fragmented and it is difficult to have a clear picture regarding best practices or recommendations for the measurement of tactile sensitivity in the food context. Future studies should aim to methodological harmonization for application in the food behavior area, with a design of experiment combining different aspects of tactile sensitivity to food, focusing on the thresholds and perceived intensity of textural parameters as well as affective and behavioral responses, and covering the whole spectrum of tactile texture perception (mechanical, geometrics, and surface), including the dynamics of perception.

Abstract
Background Children do not eat the recommended amounts of vegetables, and school-based nutrition education has not been found to impact this behavior. Cooking education is associated with improved children's culinary literacy (CL) and eating behaviors. This study investigated the impact of a culinary literacy (CL) curriculum on children's acceptance of vegetable-added (mushrooms) recipes, CL, self-efficacy to cook (SE), and willingness to try vegetables (WV). Methods A convenience sample of 39 fourth and fifth graders were exposed to a six-lesson virtual CL curriculum that taught basic cooking skills and how to prepare six recipes, including three traditional recipes and the same recipes with added vegetables. Results Children who participated in the CL curriculum accepted vegetables added to pizza pockets, but vegetables added to macaroni and cheese and fajitas negatively affected the acceptance of recipes. Children improved their CL and SE but did not show a significant change in their WV. Conclusion Findings suggest that CL programs focusing on vegetables may drive factors associated with dietary behavior change, SE, and acceptance of vegetables. Future studies should consider CL as a potential method to improve vegetable intake in children in tandem with nutrition education or as a sole intervention. The study was limited by its small sample size, the virtual setting, and the use of mushrooms as the primary vegetable source. Future studies should be conducted with a larger sample size, in a traditional classroom setting, use a variety of vegetables, and collect qualitative data on the sensory characteristics affecting children's WV.

Abstract
The non-Newtonian fluid-solid interaction food has complex physical properties and complicated contact force, which brings the greater technical challenge to improving the food fetching rate. In this work, we used the smooth particle hydrodynamics and finite element coupling method for a node-to-surface penalty function contact to characterize the contact forces between non-Newtonian fluid food and solid foods. The shear rheological properties and density of non-Newtonian fluid food, including xanthan gum (XG) and guar gum (GG), were investigated by a viscometer and densitometer, respectively. The results showed that the shear viscosity of non-Newtonian fluid food depends to some extent on the mass ratio of the thickening gums. We investigated the effects of the end-effector with different fetching velocities and different inclination angles, and the nut root powder paste (NRPP) food with different ratios of XG and GG, on the fetching rate, stress-strain, and motion behavior. The results showed that the stress increased with increasing v1 and w; however, the v2 had less effect on the stress. The sparseness of the distribution of solid food was related to the v1 and w, whereas it was less influenced by the v2 . The distribution of solid food became denser in the X-Z plane and sparser in the X-Y plane with increasing inclination angle. The motion behavior of viscoelastic solid foods depended on the mass ratio of XG to GG dissolved in NRPP. The present work can provide a theoretical foundation for meal-assisting robots and robots in the field of food engineering with the task of improving the food fetching rate.

Abstract
Background Good health requires healthy eating. However, individuals with eating disorders, such as anorexia nervosa, require treatment to modify their dietary behaviours and prevent health complications. There is no consensus on the best treatment practices and treatment outcomes are usually poor. While normalising eating behaviour is a cornerstone in treatment, few studies have focused on eating and food-related obstacles to treatment. Objective The aim of the study was to investigate clinicians' perceived food-related obstacles to treatment of eating disorders (EDs). Design Qualitative focus group discussions were conducted with clinicians involved in eating disorder treatment to get an understanding of their perceptions and beliefs regarding food and eating among eating disorder patients. Thematic analysis was used to find common patterns in the collected material. Results From the thematic analysis the following five themes were identified: (1) ideas about healthy and unhealthy food, (2) calculating with calories, (3) taste, texture, and temperature as an excuse, (4) the problems with hidden ingredients and (5) the challenges of extra food. Discussion All identified themes showed not only connections to each other but also some overlap. All themes were associated with a requirement of control, where food may be perceived as a threat, with the effects of food consumption resulting in a perceived net loss, rather than a gain. This mindset can greatly influence decision making. Conclusions The results of this study are based on experience and practical knowledge that could improve future ED treatments by enhancing our understanding the challenges certain foods pose for patients. The results may also help to improve dietary plans by including and explaining challenges for patients at different stages of treatment. Future studies could further investigate the causes and best treatment practices for people suffering from EDs and other eating disturbances.

Abstract
Thermal processing of white radish using retort sterilization at different temperatures was investigated according to the dimension of the package. Four different samples with the same weight and volume were placed in packages with different dimensions. The degree of sterilization (i.e., F0-value) at the cold point targeted at 6 min was determined based on experimental data and heat transfer simulation. The sterilization time was considerably increased with a decrease in surface area to unit volume ratio (φ) at each temperature. The sterilization time for the sample with the highest φ (155.56) was approximately five times faster than the sample with the lowest φ (72.22) at all heating temperatures. Numerical simulation conducted with a proper heat transfer coefficient (h) showed mostly good agreement with the experimental data (RMSE < 2 °C). Changes in color and total phenolic content were higher for samples heated at higher temperatures. Hardness values of white radish samples measured for center and edge parts separately were more uniform for samples with a high φ. Results in this study suggest that optimizing heating conditions of root vegetables must consider their package dimensions to satisfy quality attributes after sterilization. Numerical simulation can be utilized as a useful tool to design the sterilization process.

Abstract
Texture properties of foods are particular drivers for food acceptance and rejection in children. The texture preferences follow the developmental progression of the child and these changes modulate the present and future food habits. This paper reviews the development and factors influencing texture preferences in children and the methods in food texture research with children. The child's acceptance of more complex food textures is age-dependent. The progression is indorsed by the development of oral processing skills at an early age and bolstered by repeated exposures to foods with varying textures. Children generally reject foods containing pieces or bits (i.e., geometrical textural properties); however, the impact of mechanical textural properties on food acceptance is less clear. Child characteristics such as food neophobia, picky eating, and tactile over-responsivity, negatively affect the acceptance of more diverse food textures. Depending on the child's age, the prevailing methods of characterizing food texture preferences in children include observational techniques and self-reported questionnaires. Despite knowledge of children's development of masticatory skills, learning, and cognitive abilities, the relationships of these changes to food texture acceptance and the recommended test methodology for evaluating product texture acceptance in this period of life are still limited.

Subjective touch sensitivity leads to behavioral shifts in oral food texture sensitivity and awareness. Sci Rep 2021; 11:20237.

Abstract
Neurotypical individuals have subjective sensitivity differences that may overlap with more heavily studied clinical populations. However, it is not known whether these subjective differences in sensory sensitivity are modality specific, or lead to behavioral shifts. In our experiment, we measured the oral touch sensitivity and food texture awareness differences in two neurotypical groups having either a high or low subjective sensitivity in touch modality. To measure oral touch sensitivity, individuals performed discrimination tasks across three types of stimuli (liquid, semisolid, and solid). Next, they performed two sorting exercises for two texture-centric food products: cookies and crackers. The stimuli that required low oral processing (liquid) were discriminated at higher rates by participants with high subjective sensitivity. Additionally, discrimination strategies between several foods in the same product space were different across the groups, and each group used attributes other than food texture as differentiating characteristics. The results show subjective touch sensitivity influences behavior (sensitivity and awareness). However, we show that the relationship between subjective touch sensitivity and behavior generalizes beyond just touch to other sensory modalities.
