Storage conditions can affect the stability of extra virgin olive oil, with adverse results on quality. The aim of this study is to examine changes in the chemical composition and sensory characteristics of the oil resulting from prolonged storage at different temperatures and depending on the type of container. The influence on the quality of the oil was also considered, based on the analysis of quality parameters, the total phenol contents, changes in minority compounds, the variation of the trolox equivalent antioxidant capacity values (TEAC) and sensory features. At both room temperature (RT) and refrigerated temperature, all container types had the same surface area of exposure to light and air. All the oils stored showed losses in both qualitative properties and minor components, as well as antioxidant capacity and sensory features. This was especially true for oils stored in polyethylene terephthalate and glass, but less so for those stored in Tetra‐Brik®.

Plant seeds are major sources of nutrients and bioactive compounds for human beings and vary across different locations. In addition, they are under used foods that could be a good complement for the daily nutrition of people. Therefore, the aim of this study was the analysis of different physical parameters, nutrients and bioactive compounds of 60 plant seeds belonging to 48 species and 9 families. The seeds were collected in 2016-2017 in the Raipur area, India (21.25°N 81.63°E), from three different locations. Fat, protein, starch, total polyphenols and mineral contents ranged from 0.7 to 44.2, 1.6 to 68.5, 11.3 to 84.0, 0.01 to 3.85 and 0.67 to 4.91 g/100 g (dry weight) respectively. Regarding physical properties, the heavier seeds were covered with thick testa over the range of 3.0 to 40% of the seed mass. Higher moisture and ash fractions for the starchy (cereal and pulses) and weed seeds were also found. The most abundant mineral elements in the seeds were P, S, K, Mg, Ca, Fe and Zn. Finally, it was calculated the contribution of the consumption of seeds to the daily macronutrients and micronutrients intake for Indian population, reaching up to 38, 13 and 25% for proteins, fat and carbohydrates respectively.

This study aimed to analyse the association between socioeconomic status (SES) and fatness and fitness in preschoolers. 2,638 preschoolers (3-5 years old; 47.2% girls) participated. SES was estimated from the parental educational and occupational levels, and the marital status. Fatness was assessed by body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR). Physical fitness components were assessed using the PREFIT battery. Preschoolers whose parents had higher educational levels had lower fatness (P < 0.05). BMI significantly differed across occupational levels of each parent (P < 0.05) and WHtR across paternal levels (P = 0.004). Musculoskeletal fitness was different across any SES factor (P < 0.05), except handgrip across paternal occupational levels (P ≥ 0.05). Preschoolers with high paternal occupation had higher speed/agility (P = 0.005), and those with high or low maternal education had higher VO 2 max (P = 0.046). Odds of being obese and having low musculoskeletal fitness was lower as SES was higher (P < 0.05). Those with married parents had higher cardiorespiratory fitness than single-parent ones (P = 0.010). School-based interventions should be aware of that children with low SES are at a higher risk of obesity and low fitness already in the first years of life.
