FOODBALT 2014 APPLICATION OF ENZYMATIC TREATMENT TO IMPROVE THE CONCENTRATION OF BIOACTIVE COMPOUNDS AND ANTIOXIDANT POTENTIAL OF WHEAT AND RYE BRAN
Abstract The present study was undertaken to establish the effect of enzymatic treatment on the content of total phenolic compounds and antioxidant activity in enzymatically treated bran. Enzymatic hydrolysis of bran was carried out by α-amylase from Bacillus amyloliquefaciens (Sigma Aldrich) for breakdown the bonds between glucose monomers in starch. Multi enzyme complex (Viscozyme L) containing a wide range of carbohydrases were used for depolymerisation of cellulose and hemicelluloses molecules. The 80% ethanol was used to extract the antioxidant compounds from bran. Free radical scavenging activity of samples was measured using 2.2-diphenyl-1-picrylhydrazyl (DPPH). Assay and the data were expressed in Trolox equivalents (TE) per 100 g -1 of sample, as well the reducing power was determined using ferric reducing antioxidant power (FRAP) assay and the data were expressed in the same indices. The obtained results showed that the enzymatically treated bran samples had the highest concentration of total phenolic compounds, on the other hand the enzymatically treated bran showed higher antioxidant potential than nonenzymatically treated bran samples. Extract from enzymatically treated rye bran had the highest concentration of phenolic compounds, 1230±42.57 mg GAE 100 g -1 DW. The lowest concentration of phenolic compounds was found in untreated wheat bran samples and this amount was equal to 377±9.78 mg GAE 100 g -1 DW. Two different methods of evaluation of the bran antioxidant activity showed potential usefulness of enzymatic treatment
Relationship of Compositional, Mechanical, and Textural Properties of Gluten-Free Pasta Using Different Quinoa (Chenopodium quinoa) Varieties
Quinoa epitomizes the drive for healthier foods with ethnic concepts in developed countries, particularly among millennials. As a result, the popularity of quinoa as a gluten-free alternative has steadily grown over the last 20 years. Despite this, little is known about the impact of specific varieties on processed foods. The purpose of this study was to examine the impact of quinoa varieties (variety and content) on the mechanical and textural properties of buckwheat-based extruded pasta (spaghetti). Peruvian native (var. rosada taraco, kuchivila, negra collana, and mistura) and Latvian-grown (var. titicaca) varieties were independently incorporated to pasta between 5 and 20% (w/w). Pasta containing 20% quinoa var. negra collana, which presented the largest content of fiber and lowest content of saponin, was strongly associated to structural resilience (i.e., cohesiveness, firmness). Conversely, pasta containing 20% quinoa var. Titicaca appeared structurally weak (i.e., smooth). The addition of saponin-containing varieties to pasta (20%), such as rosada taraco and mistura, resulted in resilient structures with little effect on taste (incl. bitterness). Despite initial stability, pasta containing 20% quinoa var. kuchivila suffered heavy structural damage. In conclusion, the relationship of compositional, mechanical, and textural properties of pasta was strongly variety-dependent

Consumption of fibre rich foods: comparative study in different countries
Foods such as fruit, vegetables, and cereals, and particularly whole grain, are rich in dietary fibre and have been proved to have multiple beneficial effects for the human health. The present research was designed to assess some eating practices related to fibre-rich foods in different countries, namely Argentina, Croatia, Hungary, Latvia, Portugal, and Romania. A cross-sectional descriptive study was undertaken on a sample of 4905 adult participants, obeying all ethical guidelines for this type of research. Regarding the data treatment, basic statistics was complemented with the tree classification analysis. Generally, the results show a low consumption of salads and vegetables, i.e., up to 11 servings/week (for 78.2% of participants), with Croatia in the lead (86.6%). Regarding fruit, a great majority of data also indicated low consumption (92.3%), most especially for Latvia (98.3%). The level of consumption of whole cereals was also low (72.6%), particularly for Latvia (90.0%). The tree classification analysis showed that while the first discriminant variable for the consumption of salads and vegetables was country, followed by education, for the consumption of fruit, it was country and then sex, and finally, for the consumption of whole cereals, it was sex and followed by country. The results allowed the conclusion that the consumption of foods rich in dietary fibre was very low for these countries, highlighting the necessity to implement strategies that incentivise the consumption of such foods, which are very important for a healthy diet
Emotions and Food Consumption: Emotional Eating Behavior in a European Population
Emotion can reflect in the perception of food consumption. An increase in food intake during emotional and psychological conditions may have a negative impact on human health. The aim of this cross-sectional study was to determine the associations between food consumption, emotional eating behavior, and emotional conditions such as stress, depression, loneliness, boredom eating, maintaining vigilance and alertness, and emotional food consolation. We used a Motivations for Food Choices Questionnaire (Eating Motivations, EATMOT) to determine the emotional aspects of food consumption in 9052 respondents living in 12 European countries between October 2017 and March 2018. Ordinal linear regression was used to identify the associations between the emotional eating behavior and emotional conditions such as stress, depression, loneliness, emotional consolation, and reasons to improve physical and psychological conditions. The regression models confirmed the associations between food consumption, emotional conditions, and emotional eating behavior. Associations were found between the emotional eating behavior and stress (odds ratio (OR) = 1.30, 95% confidence interval (CI) = 1.07â1.60, p = 0.010), depressive mood (OR = 1.41, 95% CI = 1.40â1.43, p < 0.001), loneliness (OR = 1.60, 95% CI = 1.58â1.62, p < 0.001), boredom (OR = 1.37, 95% CI = 1.36â1.39, p < 0.001), and emotional consolation (OR = 1.55, 95% CI = 1.54â1.57, p < 0.001). Emotional eating was associated with an effort to improve physical and psychological conditions, such as controlling body weight (OR = 1.11, 95% CI = 1.10â1.12, p < 0.001), keeping awake and alert (OR = 1.19, 95% CI = 1.19â1.20, p < 0.001) and consumption to feel good (OR = 1.22, 95% CI = 1.21â1.22, p < 0.001). In conclusion, emotions might provoke emotional eating behavior. The appropriate way to handle stress, depression, or other emotional states is important in conditions of being emotionally overwhelmed. The public should be educated on how to handle different emotional states. The focus should be moved somehow from emotional eating and the consumption of unhealthy food to healthy lifestyle practices, including regular exercise and healthy eating habits. Thus, it is necessary to halt these negative health effects on human health through public health programs.info:eu-repo/semantics/publishedVersio
Influence of sociodemographic factors on eating motivations - modelling through artificial neural networks (ANN)
This study aimed at investigating the influence of some sociodemographic factors on the eating motivations. A longitudinal study was carried conducted with 11960 participants from 16 countries. Data analysis included t-test for independent samples or ANOVA, and neural network models were also created, to relate the input and output variables. Results showed that factors like age, marital status, country, living environment, level of education or professional area significantly influenced all of the studied types of eating motivations. Neural networks modelling indicated variability in the food choices, but identifying some trends, for example the strongest positive factor determining health motivations was age, while for emotional motivations was living environment, and for economic and availability motivations was gender. On the other hand, country revealed a high positive influence for the social and cultural as well as for environmental and political and also for marketing and commercial motivations.This is the peer-reviewed version of the following article: Guine, R.

Investigation of the Level of Knowledge in Different Countries about Edible Insects: Cluster Segmentation
This study aimed to investigate the level of knowledge about edible insects (EIs) in a sample of people from thirteen countries (Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey). Data collection was based on a questionnaire survey applied through online tools between July and November 2021. For data analysis, techniques such as factor analysis, cluster analysis, and chi-square tests were used, with a signiïŹcance level of 5%. A total of 27 items were used to measure knowledge on a ïŹve-point Likert scale. Applying factor analysis with principal components and Varimax rotation, a solution that explains about 55% of variance was obtained. This accounts for four factors that retained
22 of the 27 initial items: F1 = Sustainability (8 items), F2 = Nutrition (8 items), F3 = Production Factors (2 items), and F4 = Health Concerns (4 items). Internal consistency was evaluated through Cronbachâs alpha. The cluster analysis consisted of the application of hierarchical methods followed by k-means and produced three clusters (1ââfearfulâ, 2ââfarming,â and 3ââecologicalâ individuals). The characterisation of the clusters revealed that age did not inïŹuence cluster membership, while sex, education, country, living environment, professional area, and income all inïŹuenced the composition of the clusters. While participants from Mexico and Spain were fewer in the âfearfulâ cluster, in those from Greece, Latvia, Lebanon, and Turkey, the situation was opposed. Participants from rural areas were mostly in cluster 2, which also included a higher percentage of participants with lower income.
Participants from professional areas linked with biology, food, and nutrition were mostly in cluster 3. In this way, we concluded that the level of knowledge about EIs is highly variable according to the individual characteristics, namely that the social and cultural inïŹuences of the different countries lead to distinct levels of knowledge and interpretation of information, thus producing divergent approaches to the consumption of insectsâsome more reluctant and measuring possible risks. In contrast, others consider EIs a good and sustainable protein-food alternative.info:eu-repo/semantics/publishedVersio
Investigation of the level of knowledge in different countries about edible insects : cluster segmentation
This study aimed to investigate the level of knowledge about edible insects (EIs) in a
sample of people from thirteen countries (Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico,
Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey). Data collection was based on
a questionnaire survey applied through online tools between July and November 2021. For data
analysis, techniques such as factor analysis, cluster analysis, and chi-square tests were used, with
a significance level of 5%. A total of 27 items were used to measure knowledge on a five-point
Likert scale. Applying factor analysis with principal components and Varimax rotation, a solution
that explains about 55% of variance was obtained. This accounts for four factors that retained
22 of the 27 initial items: F1 = Sustainability (8 items), F2 = Nutrition (8 items), F3 = Production
Factors (2 items), and F4 = Health Concerns (4 items). Internal consistency was evaluated through
Cronbachâs alpha. The cluster analysis consisted of the application of hierarchical methods followed
by k-means and produced three clusters (1ââfearfulâ, 2ââfarming,â and 3ââecologicalâ individuals).
The characterisation of the clusters revealed that age did not influence cluster membership, while sex,
education, country, living environment, professional area, and income all influenced the composition
of the clusters. While participants from Mexico and Spain were fewer in the âfearfulâ cluster, in those
from Greece, Latvia, Lebanon, and Turkey, the situation was opposed. Participants from rural areas
were mostly in cluster 2, which also included a higher percentage of participants with lower income.
Participants from professional areas linked with biology, food, and nutrition were mostly in cluster 3.

Edible Insects: Perceptions of Marketing, Economic, and Social Aspects among Citizens of Different Countries
Because edible insects (EI) have been, in recent years, recommended as a nutritious animal protein food with enormous environmental advantages over other sources of animal protein for human consumption, studies aimed at investigating the consumer perspective have become more prominent. Hence, this study intended to examine the perceptions of participants from different countries about the commercialization and economic and social impacts of edible insects. The study was made using a questionnaire survey, and data were collected in Brazil, Croatia, Greece, Latvia, Lebanon, Lithuania, Mexico, Poland, Portugal, Romania, Serbia, Slovenia, Spain, and Turkey. The final number of received answers was 7222 participants. For the treatment of the results, different statistical techniques were used: factor analysis, internal reliability by Cronbachâs alpha, cluster analysis, ANOVA to test differences between groups, and Chi-square tests. The results obtained confirmed the validity of the scale, constituted by 12 out of the 14 items initially considered, distributed by 4 factors: the first related to the economic impact of EIs, the second related to the motivation for consumption of EIs, the third related to the places of purchase of EIs, and the fourth corresponding to a question presented to the participants as a false statement. A cluster analysis allowed identifying three clusters, with significant differences between them according to all the sociodemographic variables tested. Also, it was found that the participants expressed an exceptionally high level of agreement with aspects such as the difficulty in finding EIs on sale, knowledge acting as a strong motivator for EI consumption, and the role of personalities and influencers in increasing the will to consume EIs. Finally, practically all sociodemographic variables were found to be significantly associated with perceptions (country, sex, education, living environment, and income), but not age. In conclusion, the perceptions about EI commercialization were investigated and revealed differences among samples originating from different countries. Moreover, the sociodemographic characteristics of the participants were found to be strongly associated with their perceptions.info:eu-repo/semantics/publishedVersio
Evalution through artificial neural networks of the sociodemographic Influences on food choices
Introduction: The EATMOT Project is a multinational study that is being carried out in 16
countries about different eating motivations, given their recognized importance in the definition
of peopleâs dietary patterns.
Objective: This study investigated the influence of sociodemographic factors on some types of
eating motivations, specifically: health related factors; economic and availability aspects;
emotional determinants; social, cultural and religious influences; marketing and advertising
campaigns and finally environmental concerns.
Methods: This is a longitudinal observational study carried out on a non-probabilistic sample
with 11960 participants. For the analysis of the data were used the T-test for independent samples or ANOVA with Post-Hoc Tukey HSD, depending on the case. The modelling through
artificial neural networks included 7 input variables (sociodemographic characteristics) and 6
output variables (the eating motivationsâ groups).
Results: Variables like age, marital status, country, living environment, level of education or
professional area significantly influenced all the types of eating motivations analysed. However,
regarding gender, no significant differences were observed for two of the six types of
motivations analysed: economic & availability and marketing & commercial. The results of the
ANN modelling showed that the strongest positive factors determining the eating motivations
were age for health, country for emotional motivations, gender for economic & availability,
country for social & cultural, country for environmental & political, and finally country also for
the marketing & commercial motivations.
Conclusions: These results highlight the importance of the sociodemographic characteristics as
determinants for eating patterns around the globe, and particularly the geographic location.info:eu-repo/semantics/publishedVersio
