Effect of sensory exposure on liking for fat- or sugar-reduced biscuits

This study investigates the effect of exposure to fat- or sugar-reduced biscuits on liking for these products. Two sets of biscuits were manufactured, each including a standard variant and 4 variants differing by the level of reduction of either fat or sugar content, to 33% of fat content or 28% of sugar content. Biscuit consumers were recruited to eat either the fat (n ¼ 113) or the sugar-reduced set of biscuits (n ¼ 106). They participated in 5 testing sessions, once a week, in laboratory conditions. During each session, they rated their liking of the 5 variants. At the end of each of the 4 first sessions, consumers were given 16 biscuits for their home consumption during the week. Partic…

Can improving a biscuit's nutritional characteristics be compatible with maintaining it sensory quality?

Poster (1 page) ; http://www.pangborn2013.com/; International audience; Authorities encourage people to reduce fat and sugar consumption in public campaigns such as the National Nutritional Health Program in France. French producers are also encouraged to improve the nutritional composition of well-known commercial products by reducing fat and/or sugar contents. The objective of our study was to determine whether it was possible to do so while maintaining the sensory quality of the reformulated products. The study dealt with the impact of fat and sugar reduction on liking and sensory perception of 6 types of French commercial biscuits and cakes. For each type of product, one example of the …

Maternal weaning practices and their impact on infant's acceptance of new food

Objective. The introduction of solid foods is a major step in the development of food behaviour. Previous studies showed that higher sensory variety in weaning period can later influence infant's acceptance of new food. The aim of the present study is (i) to describe precisely the different maternal weaning practices, (ii) to relate them with the individual mothers' and infants' characteristics, (iii) to study if these practices could impact infant's acceptance of new foods. Methods. Mothers (n=121) were requested to record each food proposed to their infant detailed from a sensory point of view and to score the level of its acceptance at the 4 first presentations. The beginning of the wean…

Creation of a food taste database using an in-home "taste" profile method

International audience; The purpose of this study was to create a food 'taste' database using an innovative in-home profile method. The five basic tastes and fat sensation were studied. The proposed method consisted in an intensive training in laboratory (55 h, 5 months) immediately followed by an in-home measurements phase (8 months) during which 12 trained panelists had to evaluate the five tastes and fat sensation of the foods they typically consumed. The rating scales were inspired by scales used in the Spectrum (TM) method. During the in-home measurement phase, ratings were reported thanks to a web-based tool and each month the panelists returned to the laboratory for a 2-h retraining …

Portion size selection in children: Effect of sensory imagery for snacks varying in energy density

Food sensory imagery - creating a vivid mental image of the sensory experience of eating - can lead to the selection of smaller portions because it serves as a reminder that eating enjoyment does not necessarily increase with portion size. The evidence is mostly limited to adults and to energy-dense foods for which it is particularly difficult to predict the satiating effects of consumption quantity. The objective was to study how food sensory imagery influences portion size selection of foods varying in energy density (brownie and applesauce) by 7- to 11-year-old children. During after-school time, 171 children were randomized into two conditions. Children in the food sensory imagery condi…

Complementary feeding: what, when and how in OPALINE mothers? Consequences on infant's food acceptance.

National audience; The introduction of weaning foods is a major transition in the development of infants’ eating behavior. Previous studies showed that greater variety at the beginning of the weaning period can later influence an infant’s acceptance of new foods. The aim of the present study was to describe maternal feeding practices in the first year (breastfeeding duration, age at the initiation of weaning, variety of new foods introduced) and to study whether they impacted infants’ later acceptance of new foods in a longitudinal survey of French children’s eating behavior. Mothers (n = 203) were asked to record each food offered to their infants from the beginning of the weaning period t…

Development of a questionnaire to measure attraction toward sweet, salty, and fatty foods in children

Childhood obesity may be responsible for a major alteration of life quality in children and in future adults. The causes of obesity are multiple and obesity results from a chronic imbalance between food intake and energy expenditure. The challenge is to understand the cause of this imbalance. In this context, this study aimed at evaluating the contribution of the attraction toward salty, sweet and fatty foods. Thus, the first aim of this study was to establish a tool to assess children’s attraction toward sweet, salty and fatty foods that could be used later in large-scale cohorts. The second objective was to compare this questionnaire to sensory tests measuring the overall liking for sweet…

Liking the odour, liking the food. Toddlers' liking of strongly flavoured foods correlates with liking of their odour

Olfaction plays a significant role in the sensing of foods. However, little information is available at any age on the relationship between the hedonic responses to given food odours and the effective liking and disliking of foods bearing these same odours. The present study aimed to assess the relationships between food odour liking and liking of the corresponding foods. This study relied on a longitudinal design involving 235 toddlers who were assessed for both their observed liking of a set of food odours and their parent-reported liking of foods at 12 and 22 months. To assess odour liking, eight odorants representing pleasant and unpleasant foods were presented in bottles along with neu…

Parental practices perceived by children using a French version of the Kids’ Child Feeding Questionnaire

WOS:000293677900024; International audience; About 18% of 6-11-year-old French children are overweight, of whom 3.3% are obese. Parental feeding practices, especially restriction and pressure-to-eat, seem to promote overeating in children. Since no tool was available for the perception of parental feeding practices of French children, our aim was to validate a French version of the Kids'Child Feeding Questionnaire (KCFQ, Carper, Orlet Fischer, & Birch, 2000), and to determine the relationship between KCFQ's dimensions and children's standardised body mass index (BMI z-scores). The questionnaire was completed by 240 normal-weighted or overweight children between the age of 9 and 11. The vali…

Unravelling some early determinants of liking for vegetables at 2 years: a longitudinal study from pregnancy to 2 years

International audience; Food preferences guide food choices, and impact nutritional status, but their early origin needs clarification. The study aimed at understanding the early determining factors of the liking of vegetables (LVeg) at 2y, taking into account peri- and post-natal feeding experiences, children's acceptance of food tastes and odors and parental feeding practices. In a cohort of children (n 314), the milk, complementary feeding (CF) and table feeding received by children and the diet consumed by mothers during pregnancy/lactation were recorded by diaries. The acceptance of food tastes was evaluated in the lab at 3, 6, 12, 20mo; and of food odors at 8, 13, 22mo. Parental feedi…

Should I use touchscreen tablets rather than computers and mice in TDS trials?

International audience; Internet technologies are increasingly used as tools in sensory analysis. Thus, it would be a natural step forward for sensory science to move beyond the laboratory, into people's homes. Therefore, working with consumer IT devices like touchscreen tablets in sensory science should be taken into consideration. Working with the intuitive concept of dominance, Temporal Dominance of Sensations (TDS) requires a non-analytical answer from the subject. Using a touchscreen tablet instead of a classic mouse could reduce the cognitive load and favor a more instinctive answer. Indeed, it was proven that touch interaction is natural and efficient, and that finger pointing is fas…

Expectation, liking and purchase behaviour under economical constraint

Abstract A panel of 123 consumers from Dijon and Nantes rated their liking for six orange juices (two pure juices, two juices made with concentrate and two nectars) in a blind condition, and then with information about the type of juice and packaging. Expectations induced by the information were also measured and the effect of this expectation on their evaluations were studied, as well as the role of the price on the purchase behaviour when the consumers were placed in a situation of choice under economical constraint. When discrepancy between blind rating and expectation was large, consumers generally moved their ratings towards expectation when they tasted a product in presence of informa…

Product information, hedonic evaluation, and purchase decision: an experimental study of orange juice

AbstractTwo randomly sampled groups of subjects were endowed with real budgets and placed in 5 different budget/price situations. In each situation they had to evaluate 6 orange juices and complete a demand table. At the end of the experiment, one demand table was randomly selected and participants had to buy the corresponding products. In one group, participants choose after looking at the packaging in the other they could also taste the products. Results show that participants who chose without tasting, made quicker decisions, selected a larger number of variants and were more influenced by prices than those who could taste the products. Although choices appeared very heterogeneous, most …

Assessing the effect of information on the reservation price for Champagne: what are consumers actually paying for?

AbstractTwo series of Vickrey auctions have been performed to assess the effect of packaging information (bottle and label) on the reservation prices of ordinary consumers for five brut non-vintage Champagnes. As in other studies on wine tasting, packaging information is found to explain much more of the variation in willingness to pay than sensory information. Participants are unable, or unwilling, to put different values on the Champagnes after blind tasting, but significant differences in reservation prices appear when labels are disclosed. Detailed analysis of choices reveals a large heterogeneity in individual behaviors and valuations of the Champagnes included in this study. (JEL Clas…

Relationship between olfactory reactivity and food rejections in infants

N° 261; The role of hedonic reactions to odours on determining rejections of foods in infants is still debated. To answer this question, the first requirement is to have an instrument to test infants’ olfactory reactivity. Indeed, except in neonates, there is a lack of validated method. This study presents results of a new method designed to assess olfactory reactivity of 7- to 8-month-old infants. This method is based on the observation of infants’ reactions while they explored different rattles. The rattles were visually identical but differed in their odours (neutral or with a food odour). Two sequences of 6 rattles were presented to each infant. Eight odorants were used. Four odorants w…

On the consistency of liking scores : insights from a study including 917 consumers from 10 to 80 years old

Preference for 7 orange juices was recorded monadically. Three of the samples were replicates of the same juice (RJ). The 4 other samples were RJ slightly spiked with either sucrose, or citric acid, or quinine or an orange flavor. Each subject then performed a paired preference test composed of RJ and the modified juice whose score was the furthest from the RJ score. Finally, subjects were asked to choose one among 8 reasons why they preferred that sample. A number of individual statistics were computed in order to compare the consistency of liking scores within session, across ages and between genders. Women were slightly more consistent than men. However, no significant effect of age nor …

The impact of sugar and fat reduction on perception and liking of biscuits

Abstract Reducing the fat and/or sugar content in biscuits can be a way to improve their nutritional composition. Seventy-nine consumers of biscuits were recruited to study the impact of these reductions on liking and perception. Four categories of products were selected from a wide range of biscuits available at the French market. Three to six variants of each type of biscuit were produced based on reduced content of sugar, fat or both. Consumers tested the samples under laboratory conditions (6 sessions), recording their liking during initial sessions and crispiness, sweetness and fat perception during latter sessions. Sugar-reduced biscuits were perceived as less sweet than standard bisc…
