The PROFRUVE study is a controlled intervention based on the Theory of Planned Behavior (TPB), which follows those behavioral theories that have proved to be the most effective at changing infant fruit and vegetable (FV) intake pattern. The main purpose of the study is to evaluate the effectiveness of an intervention program in increasing FV consumption in schoolchildren aged 8 to 10 and based on TPB. Eligible classrooms within schools from Vitoria-Gasteiz (Basque Country, Spain) will be randomly assigned to the intervention (classrooms n = 4; children n = 86) or control (classrooms n = 4; children n = 86) group. The intervention group will receive 14 sessions of 60 min during an academic year (October to June). These sessions, designed by a multidisciplinary team, are based on TPB and are directed at modifying determinants of behavior (attitudes, subjective norms, perceived behavioral control and intention of consumption), and intake of FV itself. Both the process and the evolution of consumption and determinants of behavior will be evaluated (before, during, shortly after and a year after) using validated surveys, 7 day food records, 24 h reminders and questionnaires. This study will provide a valid and useful tool to achieve changes in the consumption of FV at school level. A negative result will be helpful in redefining new strategies in the framework of changing habits in the consumption of FV. This study has been retrospectively registered at ClinicalTrials.gov. Identifier: NCT03400891 . Data registered: 17/01/2018.

Consumption of meat from suckling lambs is typical in some regions. However, sensory differences between meat from suckling and non‐suckling lambs are barely described in previous studies. The objectives of the present study were (a) to develop a method to describe the sensory characteristics of lamb meat, including the development of sensory references for odor, flavor, and texture attributes; and (b) to study the sensory differences between lamb meat commercialized as “suckling lamb” and that commercialized without this designation. Twenty‐three sensory attributes were selected, and their corresponding sensory references were developed. A detailed procedure to evaluate the samples was also set up. This methodology was used to characterize samples (n = 48) from a survey of lamb meat from different types of stores (n = 23). Half of the samples were commercialized as sucking lamb and the other half (older lambs) without this indication. Samples were bought in two seasons (May and December) to consider possible seasonal effects. Samples were evaluated in triplicate by 12 trained assessors. Data were analyzed by ANOVA (p ≤ .05). Apart from how long juiciness was maintained (“maintained juiciness”), all the selected attributes were appropriate to discriminate between samples. Lamb meat sold as “suckling” did not differ from the other lamb samples in odor and flavor, but there were clear differences in texture attributes: meat sold as suckling lamb was tenderer and juicier, with higher crumbliness, and with lower fibrousness, chewiness, and residue than non‐suckling lamb meat. Several sensory characteristics, mainly related to odor and flavor, varied according to the season.

This study aimed to evaluate consumer perception and acceptance of non-alcoholic cocktails compared to their traditional alcoholic counterparts in a restaurant setting. Three popular cocktails—gintonic, mojito, and mule—and their non-alcoholic versions (NoLo) were assessed following a three × two experimental design. A total of 600 participants (approximately 100 per cocktail) participated at the Basque Culinary Center’s restaurant. Participants rated their liking of the cocktails using a nine-point hedonic scale and provided open-ended responses about the sensory characteristics and the consumption contexts or emotions evoked by the different cocktails. The results showed differences in the acceptance of the six cocktails, but no significant differences between the alcoholic and non-alcoholic versions, suggesting that NoLo alternatives were similarly well-received. Open-ended responses were analyzed using latent dirichlet allocation (LDA) to uncover latent topics, and Fisher’s exact test and correspondence analysis were used to identify differences in the mentioned topics per cocktail. Specific sensory attributes, emotions, and contexts were associated with each type of cocktail, but no differences were found between the alcoholic and non-alcoholic versions. These findings demonstrate the viability of non-alcoholic cocktails in real consumption settings, eliciting similar liking scores, sensory attributes, contexts, and emotions in consumers. This study also highlighted the potential of natural language processing techniques for analyzing open-ended questions.

Legislation on the quality of water intended for human consumption requires routine taste and odour controls. So far, no procedures or technical documents exist which can be used as a reference in the training of sensory assessors for tap water. This work presents the procedure for the development of a trained panel and it describes all the steps carried out: the recruitment, pre-selection, selection and training phase considering the different odours and flavours that tap water may contain. In order to analyse the performance of the assessors in the training phase, 6 parameters and 15 criteria are proposed. The assessors who fulfilled the criteria, will integrate a qualified panel to carry out tap water sensory controls. This process has shown to be suitable and strict enough to train assessors on tap water evaluation, and can therefore function as a reference for other laboratories on which to base their training and qualification of assessor panels on tap water quality control.
