Identification and quantification of flavor compounds in smoked tuna fish based on GC-Orbitrap volatolomics approach.

Cold smoking enhances the appeal of fish products, offering consumers a smooth texture and a delicate smoky flavor. This study aims to explore variations in the volatile profile from different exposure times during cold smoking processing (light, moderate, and full-cure) in tune samples. An innovative untargeted analytical approach, headspace solid-phase microextraction combined with gas chromatography and a hybrid quadrupole-orbitrap mass analyzer, was employed to identify 86 volatiles associated with the cold smoking process.

Associations between dietary behaviours and the mental and physical well-being of Swedish adolescents.

Aims: This study aims to investigate the association between dietary behaviours, overweight/obesity, and mental health and well-being among Swedish adolescents.

Methods: Data from the 2017/2018 Health Behaviour in School-aged Children (HBSC) survey of 3692 adolescents aged ≈11, ≈13, and ≈15 years was analysed. We evaluated the prevalence and association of dietary behaviours, characterised by daily intake of fruits and vegetables, consumption of sugar-sweetened beverages (SSBs) and sweets once per week, and daily consumption of family meals and breakfast, with socioeconomic and demographic factors.

Socioeconomic inequalities in adolescent mental health in the Nordic countries in the 2000s - A study using cross-sectional data from the Health Behaviour in School-aged Children study.

Background: Adolescents in Sweden experience more mental health problems and lower mental well-being than adolescents in other Nordic countries. According to the literature, one possible explanation may be differences in income inequality. The at-risk-of-poverty rate varies significantly across the Nordic countries, and the highest rate is found in Sweden.

Moderate Water Stress Impact on Yield Components of Greenhouse Tomatoes in Relation to Plant Water Status.

The scarcity of water resources affects tomato production. Deficit irrigation may optimize water management with only a low reduction in yield. Deficit irrigation scheduling based on applied water presented no clear conclusions.

Exploring Plants with Flowers: From Therapeutic Nutritional Benefits to Innovative Sustainable Uses.

Flowers have played a significant role in society, focusing on their aesthetic value rather than their food potential. This study's goal was to look into flowering plants for everything from health benefits to other possible applications. This review presents detailed information on 119 species of flowers with agri-food and health relevance.

Encouraging greater empowerment for adolescents in consent procedures in social science research and policy projects.

The United Nations Convention on the Rights of the Child emphasizes the importance of allowing children and adolescents to influence decisions that are important to them following their age and maturity. This paper explores the principles, practices, and implications around using parental versus child/adolescent consent when participating in social science research and policy development. Experiences from two studies are presented: The Confronting Obesity: Co-creating policy with youth (CO-CREATE) and the Health Behaviour in School-aged Children (HBSC) study, a World Health Organization (WHO) Collaborative Cross-National study.

The clustering of multiple health and lifestyle behaviors among Swedish adolescents: a person-oriented analysis.

Background: Knowledge of the distribution, prevalence, and clustering of multiple health and lifestyle related behaviors (HLBs) among adolescents can inform the development of effective health-promoting policies and interventions. We assessed the clustering of multiple HLBs among 11, 13 and 15-year-old Swedish adolescents and examined the socioeconomic and demographic correlates for the identified clusters.

Methods: We used data from the 2017/2018 Swedish Health Behaviour in School-aged children (HBSC) study to conduct sex and age-stratified latent class analysis (LCA).

Endocarp Development Study in Full Irrigated Olive Orchards and Impact on Fruit Features at Harvest.

Endocarp development in olive trees includes three periods: growth (Period I), massive sclerification (Period II) and maximum hardening (Period III). The two first are strongly related to yield and irrigation management. Period I was reported to coincide with mesocarp cell division and thus with final fruit size.

Hair glucocorticoid concentration, self-perceived stress and their associations with cardiometabolic risk markers in Swedish adolescents.

Background: While hair cortisol is proposed as a biomarker for chronic stress and a possible mediator linking chronic stress and cardiovascular risk in adults, studies in adolescents are scarce. We explored the associations between self-perceived stress, hair cortisol (HairF) and cortisone (HairE), and cardiometabolic risk markers in adolescents. Further, we examined whether association between self-perceived stress and HairF may depend on the use of the coping strategies "shift-persist".

Establishing a Reference Baseline for Midday Stem Water Potential in Olive and Its Use for Plant-Based Irrigation Management.

Midday stem water potential (SWP) is rapidly becoming adopted as a standard tool for plant-based irrigation management in many woody perennial crops. A reference or "baseline" SWP has been used in some crops (almond, prune, grape, and walnut) to account for the climatic influence of air vapor pressure deficit (VPD) on SWP under non-limiting soil moisture conditions. The baseline can be determined empirically for field trees maintained under such non-limiting conditions, but such conditions are difficult to achieve for an entire season.

Screening for Innovative Sources of Carotenoids and Phenolic Antioxidants among Flowers.

Flowers have been used for centuries in decoration and traditional medicine, and as components of dishes. In this study, carotenoids and phenolics from 125 flowers were determined by liquid chromatography (RRLC and UHPLC). After comparing four different extractants, the carotenoids were extracted with acetone: methanol (2:1), which led to a recovery of 83%.

Does the family affluence scale reflect actual parental earned income, level of education and occupational status? A validation study using register data in Sweden.

Aim: To examine the external validity of the Family Affluence Scale (FAS) among adolescents in Sweden by using register data for parental earned income, level of education and occupational status.

Methods: Data from the baseline (2015-2019) of the Study of Adolescence Resilience and Stress (STARS), comprising 2283 13-year-olds in the region of Västra Götaland, were used. The FAS III consists of six items: unshared bedroom, car ownership, computer/tablet ownership, dishwasher, number of bathrooms and number of holidays abroad.

Subjective health complaints in early adolescence reflect stress: A study among adolescents in Western Sweden.

Mental health problems are common among Swedish adolescents and are sometimes referred to as 'stress-related'. The overall aim of this study is to do an analysis of subjective health complaints (SHCs) and perceived general stress among adolescents in Sweden, both their prevalence and association, by gender, migration background, family structure and socioeconomic conditions. Data from the baseline (comprising 2283 adolescents aged 13) of the STudy of Adolescence Resilience and Stress (STARS) study in Västra Götaland in Sweden were used.

How does water stress affect the low molecular weight phenolics of hydroSOStainable almonds?

Water scarcity is a threat for food production because, water, is more and more limited and force farmers to use new deficit irrigation (DI) strategies without affecting fruit yield and quality. No information exists on almond polyphenols and proanthocyanidins (PAs) produced under DI. The present work studied the effect of 2 regulated DI (RDI) and one sustained (SDI) on the low molecular weight phenolics together with the antioxidant activity (AA) in almonds.

Chemical and sensorial characterization of spray dried hydroSOStainable almond milk.

Background: Water scarcity is a worldwide problem that leads to environmental and economic issues. Agriculture is one of the main consumers of water for irrigation and fertilization and almond is the major tree nut crop in the Mediterranean area. Furthermore, there is a continuous growing demand for healthy, vegan and sustainable products.

Phytoprostanes and Phytofurans-Oxidative Stress and Bioactive Compounds-in Almonds are Affected by Deficit Irrigation in Almond Trees.

Almonds have gained consumers' attention due to their health benefits (they are rich in bioactive compounds) and sensory properties. Nevertheless, information about phytoprostanes (PhytoPs) and phytofurans (PhytoFs) (new plant markers of oxidative stress and compounds with biological properties for human health) in almonds under deficit irrigation is scarce or does not exist. These compounds are plant oxylipins synthesized by the oxidation of α-linolenic acid (ALA).

School Satisfaction and School Pressure in the WHO European Region and North America: An Analysis of Time Trends (2002-2018) and Patterns of Co-occurrence in 32 Countries.

Purpose: The purpose of the study was to examine the trends between 2002 and 2018 in school pressure and school satisfaction among 15-year-old students, across countries and by gender, in the WHO European region and North America, and explore whether there are variations between countries and by gender in the co-occurrence of school pressure and school satisfaction.

Methods: Data from the 32 countries that participated in the Health Behaviour in School-aged Children study (HBSC) study between 2002 and 2018 were used. Statistical analyses included t-tests, binary logistic regression analyses, and chi-square tests, as required by each of the study aims.

Nutrition Quality Parameters of Almonds as Affected by Deficit Irrigation Strategies.

The influence of full irrigation, double-regulated (RDI) and sustained deficit irrigation (SDI) treatments on almond quality was assessed by analyzing different parameters: sugars, organic acids, antioxidant activity, total phenolic content (TPC), and volatile compounds. Almond quality studies for plants submitted to water stress are scarce, and it is essential to understand the biochemical responses of plants to water stress in maintaining fruit yield and quality. Citric acid, sucrose, antioxidant activity, and TPC were not affected by the application of studied deficit irrigation strategies (DI).

Quality Attributes and Fatty Acid, Volatile and Sensory Profiles of "Arbequina" Olive Oil.

The use of deficit irrigation techniques on olive orchards is the main trend aiming to optimize water savings while improving functional and sensory characteristics of oils from trees under deficit irrigation techniques. The brand has been defined for crops produced under water restriction conditions. olive oils obtained under two new regulated deficit irrigation and one sustained deficit irrigation treatments in "Arbequina" olive trees were evaluated by analyzing quality parameters, antioxidant activity, total phenol content, fatty acid profile, volatile compounds, and sensory descriptors.

Sensory Profile and Acceptability of HydroSOStainable Almonds.

Fresh water availability is considered highly risky because it is a finite resource, and a deficiency in water leads to numerous economic and environmental issues. Agriculture is one of the main consumers of fresh water in practices such as irrigation and fertilization. In this context, the main objectives of this study were (i) to determine the descriptive sensory profiles of four almond types grown using different irrigation strategies and (ii) to study their acceptance in a cross-cultural study (Romania and Spain).

Study of commercial quality parameters, sugars, phenolics, carotenoids and plastids in different tomato varieties.

The aim of this study was to assess commercial quality parameters, sugars, phenolics, carotenoids and plastid in diverse and little studied tomato varieties to gain insight into their commercial and functional quality and reveal possible noticeable differences. Five cherry tomato varieties and six common (i.e.

Effect of Spanish-style processing on the quality attributes of HydroSOStainable green olives.

Background: Three treatments of regulated deficit irrigation (RDI) were assayed on olive trees for table olive production. RDI provides hydroSOStainable crops. The effect of RDI treatments on the quality of raw and table olives was determined based on their: weight, pit weight, fruit/pit ratio, size, texture, colour, mineral content, antioxidant activity, total phenol content and organic acid and sugar profile.

Antioxidants (carotenoids and phenolics) profile of cherry tomatoes as influenced by deficit irrigation, ripening and cluster.

The purpose of this study was to assess the relationship between the effect of regulated deficit irrigation, cluster, developmental stages and two seasons (autumn 2015 and spring 2016) on the commercial and functional quality (carotenoids and plenolics levels) in 'Lazarino' and 'Summerbrix' tomatoes. Autumn had a positive effect on the commercial quality, with larger fruits (22% in 'Summerbrix'; 26% in 'Lazarino') and higher soluble solids (16% in 'Summerbrix'; 12% in 'Lazarino'). Total carotenoids did not change significantly with irrigation and variety while total phenolics did with the cluster and season.

Effect of the fruit position on the cluster on fruit quality, carotenoids, phenolics and sugars in cherry tomatoes (Solanum lycopersicum L.).

Cherry tomato varieties are widely consumed in many countries. They contain nutrients and health-promoting compounds like phenolics and carotenoids. The main purpose of this study was to determine how the fruit position on the cluster affected quality parameters of diverse nature (weight, soluble solids, firmness, colour, carotenoids, phenolic compounds and sugars).

Effect of regulated deficit irrigation on quality parameters, carotenoids and phenolics of diverse tomato varieties (Solanum lycopersicum L.).

This study aims to evaluate the effects of regulated deficit irrigation (RDI) and of cluster position (CI: first and second cluster; CII: third and fourth cluster; CIII: fifth and sixth cluster) on fruit quality parameters, carotenoids and phenolics in tomatoes. Three common ('Tigerella', 'Palamós' and 'Byelsa') and two cherry varieties ('Lazarino' and 'Summerbrix') were studied. The results showed that the regulated deficit irrigation with reduction of 40 and 50% in the leaf water potential in common and cherry tomatoes did not affect greatly the organoleptic quality of common tomatoes and 'Summerbrix', while cherry varieties were significantly affected with the cluster position.
