]]> Capturing food-elicited emotions : Facial decoding of children’s implicit and explicit responses to tasted samples]]> Sensory and consumer research increasingly aims to gain direct input from children to study their eating behaviour. However, answering self-administered questionnaires can be challenging for children. In this sense, the prediction of basic emotions via facial decoding, generating quantitative observational data, could offer an alternative to questionnaires.

The present study aimed to measure children’s implicit and explicit basic emotions elicited by tasting, through the use of facial decoding and compare them to children’s liking ratings in a case study with flavoured chocolate milk samples. Children aged 9–10 participated in the study (n = 48). Six samples based on two design of experiment factors Added sugar (yes / no) and Surprise flavour (peppermint / liquorice/ no added flavour) were tested. The software iMotions with the AFFDEX algorithm was used for facial decoding. For each sample, facial expression was measured immediately after tasting (implicit basic emotions). Then, children were asked to show a facial expression related to their feelings when they tasted the chocolate milk (explicit basic emotions) and rate their liking on a 7-point-scale.

Implicit and explicit basic emotion likelihoods from facial decoding were correlated to liking ratings regarding the factor Surprise flavour. As in previous studies, the measurement of implicit basic emotions discriminated samples according to negative emotions (anger and disgust) which had higher likelihoods in disliked samples with Surprise flavour (peppermint and liquorice). Facial decoding of explicit basic emotions was the only measurement discriminating samples also according to the factor Added sugar, an advantage over liking ratings. The positive emotion joy, as well as negative emotions (sadness, fear, anger, disgust and contempt), were significant in the explicit evaluation. The results add to previous literature suggesting that the measurement of implicit emotions via facial decoding can be useful to study negative emotions. Further, explicit basic emotions enhanced the discrimination of liked samples with the involved age group.

Their implicit bias towards pictures of snacks was measured via AAT. The test instruction was based on pushing or pulling the joystick according to picture category, food vs. non-food: food (18 snack pictures varying in sweetness and calorie) vs. non-food (18 pictures visually similar to the respective food stimuli). Further, children rated their expected liking of the snack pictures, answered an attitude questionnaire related to health and sugar consumption, and completed two paired preference tests tasting real samples under blind condition and choosing between a sugar and no-sugar added chocolate milk take-home pack.
The percentage of non-valid AAT responses was relatively high, leading to low testing power. There was a significant difference in approach bias between food pictures and non-food pictures; approach bias was positive for food and slightly negative for non-food. Within food pictures, no significant effect of sweetness nor calorie was found. Nevertheless, children’s approach biases were linked to their expected liking ratings, which revealed a clear preference towards high sweetness and high calorie snacks. Individual differences in children’s approach bias to pictures differing in sweetness and calorie content were related to their hunger state but not to their attitudes or preference towards chocolate milk, indicating relevance for situational food choices. In the present study, questionnaire-based measurements (affective and cognitive attitude towards sugar, sugar craving and using food as reward) were however associated with children’s preference towards chocolate milk (blind and/or informed). Higher scores in the measured attitude subscales craving for sweet food, using food as reward, affective attitude towards sweet food and cognitive attitude towards sweet food were associated with higher odds to choose the sugar added chocolate milk. Methodological considerations and recommendations with regards to the use of approachavoidance testing with children are critically discussed.]]> Galler, Martina]]> Mikkelsen, Emma]]> Næs, Tormod]]> Liland, Kristian Hovde]]> Ares, Gastón]]> Varela, Paula]]> Información sobre Derechos de Autor

]]> A Simple Automated Method for the Determination of Nitrate and Nitrite in Infant Formula and Milk Powder Using Sequential Injection Analysis]]> A fast and efficient automated method using a sequential injection analysis (SIA) system, based on the Griess, reaction was
developed for the determination of nitrate and nitrite in infant formulas and milk powder. The system enables to mix a measured
amount of sample (previously constituted in the liquid form and deproteinized) with the chromogenic reagent to produce a
colored substance whose absorbance was recorded. For nitrate determination, an on-line prereduction step was added by passing
the sample through a Cd minicolumn. The system was controlled from a PC by means of a user-friendly program. Figures of merit
include linearity (r2 > 0.999 for both analytes), limits of detection (0.32mg kg−1 NO3-N, and 0.05 mg kg−1 NO2-N), and precision
(sr%) 0.8–3.0. Results were statistically in good agreement with those obtained with the reference ISO-IDF method. The sampling
frequency was 30 hour−1 (nitrate) and 80 hour−1 (nitrite) when performed separately.
