Summary: Edible seaweed hydrocolloid-based films and coatings have gained attention due to their good properties, but limited applications due to hydrophilicity. Incorporating fruit by-product extracts can improve the performance and enable the development of active films and coatings for food. This review provides comprehensive information and highlights the potential of fruit by-product components in seaweed-based films and coatings.

Summary: This study investigated the replacement of a monolithic ion-exchange column with a UF membrane for the separation of acid whey. The concentrate obtained could be used as a starter culture substrate of kefir grains. Purification of the remaining solution was performed through nanofiltration, and the permeate showed complete removal of lactose. The dry permeate exhibited the ability to inhibit acne growth and improved anaerobic fermentation when added to a moisturizing solution.

Summary: This study developed an integrated process for the recovery of sweet goat whey components through filtration, centrifugation, pasteurization, and sequential membrane processes. The application of this process led to the retention of proteins and lactose in whey, allowing for their total recovery in cheese dairy plants. This integrated process can contribute significantly to the sustainability of small- or medium-sized goat cheese dairies.

Summary: The study found that under mild pH and temperature conditions, non-covalent interactions between proteins and polyphenols naturally occur, leading to changes in the physical properties of dispersions. Addition of polyphenols results in increased viscosity and surface tension, and decreased particle size of dispersions, changes attributed to the conjugation interactions between proteins and polyphenols.

Summary: Modeling of nanofiltration processes is usually done for dilute solutions, but in industrial applications, more concentrated solutions are often used. Recently, models for dilute NaCl solutions were extended to higher concentrations, and models for predicting NaCl retention in saturated solutions with impurities were proposed. However, there was a lack of models for intermittent NaCl concentrations. In this study, a new model was developed to fill this gap, and its validity was proven for NaCl solutions containing Na2SO4.

Summary: This study aimed to develop a stable freeze-dried synbiotic formula for use in instant milk-based beverages as a probiotic enhancer and thickener. The addition of whey protein-polysaccharides was found to improve probiotic survival during freeze-drying and storage, particularly with specific combinations showing significant effects. Subsequent ingestion of synbiotic portions in a gastrointestinal digestion simulator demonstrated the importance of a supportive food matrix in improving probiotic survival and efficiency.

Summary: The aim of this study was to analyze whether the rating of perceived exertion (RPE) and the resulting internal load (sRPE) could differ among subjects when volume and intensity are matched in young cross-country (XC) skiers. The results showed that the total training load in low-intensity sessions was higher in the group with higher RPE ratings, but the total training time did not differ significantly between the two groups. Additionally, high-intensity sessions had a larger effect on performance improvement in comparison to low-intensity sessions.

Summary: This study characterized and grouped five samples of low-fat, high-protein commercial yoghurts using electrical impedance spectroscopy and conventional analytical techniques. The results showed that the samples were divided into two main groups. Pearson's correlation analysis revealed a positive linear correlation between the impedance and rheological parameter k at average and high frequencies. Overall, the study suggests that electrical impedance spectroscopy is a promising method for characterizing and grouping yoghurts.

Summary: The aim of this study was to investigate the effects of supervised cycling sprint interval training on serum osteocalcin, lipocalin-2 and sclerostin levels, and bone mineral characteristics among obese adolescent boys. After a 12-week intervention, there were significant improvements in bone mineral content and density in the SIT group. However, no significant differences were found in osteocalcin, lipocalin-2, and sclerostin levels between the two groups.

Summary: Studies have shown that children are more physically active during outdoor recess compared to indoor recess, and the design of schoolyards plays a crucial role in stimulating their physical activity. This research aimed to investigate the influence of schoolyard environments on outdoor recess physical activity in urban and rural primary schools in Estonia. The study utilized mapping methods to describe schoolyards, recorded children's activities during outdoor recess through observations, and measured physical activity levels using accelerometers. The findings revealed that schoolyards with more space per child and natural environment elements resulted in more varied and intense physical activity during outdoor recess.

Summary: This study aimed to synthesize and characterize hydrogels prepared with alginate (ALG) and ora-pro-nobis mucilage (MOPN) by ionic gelation. The hydrogels were characterized in terms of mechanical strength, degree of swelling, morphology, chemical groups and thermal properties. The results showed that MOPN can crosslink with ALG to form gels. The hydrogel composed of ALG and MOPN showed a more amorphous, porous structure with lumps, and 0.25% (w/v) of ALG can be replaced by MOPN without significant changes in its mechanical and swelling properties.

Summary: This study aimed to evaluate the long-term effects of body composition, physical activity, and cardiorespiratory fitness on arterial health in late adolescent males. The results showed that body composition measures at puberty and cumulative cardiorespiratory fitness were independently associated with arterial structure, specifically intima-media thickness (IMT). However, there was no significant relationship between these factors and arterial function.

Summary: The demand for plant-based natural dyes has increased in recent years. The peel of pitaya (dragon fruit) is a by-product with high concentrations of betalains, which can be used as a source for extracting this pigment. Microparticles of betalains extracted from the pitaya peel were produced via freeze-drying and showed good physical-chemical properties, thermal stability, and reconstitution capacity. These microparticles can be a stable and attractive alternative to animal-based dyes.

Summary: The aim of this article is to summarize the results and compare them with previous report card results of the 2022 Estonian Physical Activity Report Card, which assessed physical activity indicators in Estonian children and youth. The national expert panel identified and graded data related to factors such as organized sports, community support, government initiatives, physical fitness, family and peer influence, school involvement, active play, active transportation, and sedentary behaviors. The report showed that while Estonia has a high participation rate in organized sports and relatively good government and community support, there is still a high number of children and youth not meeting PA guidelines, and sedentary behavior is a major concern.
