Abstract
Developing new food products for children is challenging, particularly in vulnerable groups including children with Down syndrome (DS). Focusing on children with DS, the aim of this study was to study the influence of parent liking on acceptance of food products by children with DS and demonstrate the influence of food sensory properties on indicators of food acceptance, food rejection, and challenging eating behaviours. Children (ages 1158 months) with DS (n = 111) participated in a home use test evaluating snack products with varying sensory properties as profiled by a trained sensory panel. Parents recorded their children's reactions to each food product; trained coders coded videos for eating behaviours. To understand the influence of each sensory modality on eating behaviour, ordered probit regression models were run. Results found a significant correlation between the parent liking and overall child disposition to the food (p < 0.05). From the regression analysis, the inclusion of all food sensory properties, including texture, flavour, taste, product shape and size, improved the percentage of variance explained in child mealtime behaviours and overall disposition over the base model (containing no sensory modalities), with texture having the largest influence. Overstuffing the mouth, a challenging eating behaviour, was most influenced by product texture (children ≥ 30 months), and product texture and size (children < 30 months). In both age groups, coughing/choking/gagging was most influenced by food texture and was associated with a product that was grainy and angular (sharp corners). In both age groups, product acceptance was associated with a product that was dissolvable, crispy, and savoury while rejection was associated with a dense, gummy and fruity product. These results suggest that a dissolvable, crispy texture, with a cheesy or buttery flavour are the sensory properties important in a desirable flavoured commercial snack product for children with DS; however, overall disposition must be balanced against mouth overstuffing.

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
Parental behaviours influence food acceptance in young children, but few studies have measured these behaviours using observational methods, especially among children with Down syndrome (CWDS). The overall goal of this study was to understand parent feeding practices used during snack time with young CWDS (N = 111, aged 11-58 months). A coding scheme was developed to focus on feeding practices used by parents of CWDS from a structured home-use test involving tasting variously textured snack products. Behavioural coding was used to categorise parental feeding practices and quantify their frequencies (N = 212 video feeding sessions). A feeding prompt was coded as successful if the child ate the target food product or completed the prompt within 20 s of the prompt being given without a refusal behaviour. CWDS more frequently consumed the test foods and completed tasks in response to Autonomy-Supportive Prompts to Eat (49.3%), than to Coercive-Controlling Prompts to Eat (24.2%). By exploring the parent-CWDS relationship during feeding, we can identify potentially desirable parent practices to encourage successful feeding for CWDS. Future research should build upon the knowledge gained from this study to confirm longitudinal associations of parent practices with child behaviours during feeding.

Abstract
Children with Down syndrome (DS) display a disproportionate number of health challenges, including feeding and swallowing difficulties and food texture sensitivities. To start addressing food texture challenges early in life, the aim of this research was to understand mealtime behaviors and identify preferred food textures of children with DS. Children (aged 11 to 58 months) with DS (n = 111) and without (typically developing, TD; n = 107) participated in a home use test evaluating snack products of varying textures. Parents recorded their children's reactions to each food product; a panel of trained coders coded videos for mealtime behaviors. Children were also identified as food texture sensitive (TS) or non-texture sensitive (NTS). Results showed that age, TS, the presence of a DS diagnosis and the TS*DS interaction influenced the child's behaviors to the food products. Children with DS were more likely to increase distance from the food, mouth/suck on the food, and less likely to chew/much on the food compared to children TD. Children with DS also ate significantly less than typically developing children. Similar mealtime behaviors were observed between the children with TD/<30 months of age and children with DS regardless of age (p < .05). While children with DS/TS had a higher disposition for the dissolvable texture, along with products that were salty and cheesy, children with DS/NTS had a greater tolerance for more textures in general, including crunchy and grainy. Overall, this research identified mealtime behaviors in children with DS, determined overall disposition of children with DS to foods of differences sensory properties, and demonstrated the influence of TS on a child's disposition to a food. This research will be extended to develop acceptable and innovative food products for children with DS/TS.

Abstract
The question of what to feed becomes a new challenge as an infant reaches the transition to complementary foods. Limited information is available that provides a texture progression map for complementary food introduction. Thus, the objective of this study was to determine the relationship between age and food texture experiences (FTE) in young children aged 4-36 months in the United States. A parent-reported survey was fielded with 328 children categorized into five age groups (AGs): 4-8 months (AG1), 9-12 months (AG2), 13-18 months (AG3), 19-24 months (AG4), and 25-36 months (AG5). The present study analyzed four questions focused on FTE, with statistical analyses including probit and logit models, and analysis of variance. Results showed that all 16 food textures were tried at least once (>50%) by AG3. The question answered by participants, "How well does your child manage a specific texture," showed that significant differences existed among AGs for the management of 10 food textures (including chewy, hard, soft), whereas teething alone had no effect. The most refused textures by the children were AG1-crispy (27%), AG2-leafy (23%), AG3-leafy (40%), AG4-tough meat (52%), and AG5-leafy (51%). With increasing AG, the refusal probability of nine food textures, including chewy, leafy, and rubbery, also increased (p < .05). The refusal probability of cold food temperatures decreased with increasing age (p < .05). This study observed FTE in children across AGs and provides useful information to parents and practitioners as they introduce food textures into children's diets.

Abstract
Understanding food texture sensitivity in children is important in guiding food selection. The objective of this work was to develop a short questionnaire that could be completed by parents in nonclinical settings to provide a categorization for food texture sensitivity in children. This study evaluated the distribution of children as texture sensitive (TS) or non-texture sensitive (NTS) and the predictive validity of these questions to explain rejection of specific food textures. Three sets of survey data were examined, including data from a home-use test (HUT) in children with and without Down syndrome (DS), and lingual tactile sensitivity measured by grating orientation task (GOT). From three parent-completed surveys, the use of the questionnaire yielded a similar distribution of children in the TS category (16-22%) as previously reported. TS children (4-36 months) were more likely to reject specific food textures, including chewy, hard, lumpy, and "tough meat" (p < .05). A higher percentage of children with a diagnosis of DS were TS (36.9%). Children who were TS showed increased negative behaviors to foods and ate less than NTS children. In older children (5-12 years), TS children were fussier than NTS children (p < .001). Lingual tactile sensitivity was not significantly different by TS/NTS categorization (p = .458). This study demonstrated that the use of these five questions specific to food texture provides a useful tool in categorizing a child as TS/NTS, with this information being useful in selecting preferred food textures. Future studies involving these TS questions should perform psychometric assessments and measures of criterion validity using other questionnaires.
