Objective. To reveal the dependence of the alimentary factor’s influence on the formation of nutritional status disorders in organized groups of school-age children. Patients and methods. A sample questionnaire and an anthropometric survey of 488 school children aged 8–9 years (group 1), 12–13 years (group 2) and 16–17 years (group 3) were conducted. Nutritional status was analyzed by anthropometric measurements using regional modified regression scales for the Samara Region. The analysis of the results obtained, including the risk of nutritional status disorders, was performed with the use of parametric statistical procedures. Results. Hot school meals were provided to 85.6% of pupils in grades 2–3, to 55.6% of sixth graders and 36.4% of pupils in the senior classes. A rational diet was revealed in 18.3% of cases in the junior school group and only in 7.0% of cases in group 3. The consumption of bread and bakery products, vegetables, fruits, milk, and dairy products increases by high school age. The frequency of fish and seafood consumption in most cases in each age group is limited to a few meals per month. Anthropometric studies showed a significant increase in the proportion of children with nutritional status disorders (underweight or overweight) between the ages of 12 and 17. Conclusion. The risk of nutritional status disorders in the examined children was due to the high frequency of consumption of bakery and confectionery products, decreased consumption of fruits and vegetables, and infrequent meals. Key words: school meals, regimen, nutritional structure, nutritional status

Smart packaging is an emerging technology that has a great potential in solving conventional food packaging problems and in meeting the evolving packaged vegetables market needs. The advantages of using such a system lies in extending the shelf life of products, ensuring the safety and the compliance of these packages while reducing the food waste; hence, lessening the negative environmental impacts. Many new concepts were developed to serve this purpose, especially in the meat and fish industry with less focus on fruits and vegetables. However, making use of these evolving technologies in packaging of vegetables will yield in many positive outcomes. In this review, we discuss the new technologies and approaches used, or have the potential to be used, in smart packaging of vegetables. We describe the technical aspects and the commercial applications of the techniques used to monitor the quality and the freshness of vegetables. Factors affecting the freshness and the spoilage of vegetables are summarized. Then, some of the technologies used in smart packaging such as sensors, indicators, and data carriers that are integrated with sensors, to monitor and provide a dynamic output about the quality and safety of the packaged produce are discussed. Comparison between various intelligent systems is provided followed by a brief review of active packaging systems. Finally, challenges, legal aspects, and limitations facing this smart packaging industry are discussed together with outlook and future improvements.

Introduction: Nutrition is one of the most important environmental factors affecting human health. The frequency, as well as the quality and quantity of consumed foods are significant. Regular and rational dietary habits and correct meal composition ensure good health and fitness, whereas poor dietary habits in childhood account for an early risk of overweightness and obesity. The aim of this study was to evaluate the dietary patterns of girls and boys attending primary schools in Poland, and to identify any associations between the pupils’ dietary patterns and their sex. Materials and methods: The study was carried out in spring 2017. It covered a total of 1138 primary school pupils. A proprietary questionnaire specially designed for the study was used to investigate the pupils’ dietary patterns. The findings were then analysed with the use of MS Excel 2010 and Statistica 12.0 software.Results: According to the survey, 67.36% of the female respondents and 55.4% of the male respondents ate the recommended number of meals each day. Among the respondents 72% of the girls and 73.27% of the boys reported eating breakfast daily. Fruits and vegetables were eaten several times per day by 60.38% and 43.11% of girls, respectively, v. 50.44% and 32.39% of boys, respectively. The frequency of milk and natural yoghurt consumption was adequate in 20.07% and 10.12% of girls, respectively, v. 20% and 11.5% of boys. Sweets and salty snacks were excluded from the diet of 2.97% and 2.27% of girls, respectively, v. 3.19% and 2.12% of boys, respectively. Sweetened carbonated drinks were consumed by 11.17% of girls and 6.55% of boys. Fast food and instant foods were eliminated from the daily diet of 7.16% and 45.03% of girls, respectively, v. 6.02% and 43.19% of boys, respectively.Conclusions: Some incorrect dietary habits were identified both in girls and boys, however girls generally reported more beneficial habits. Statistically significant associations were found between the majority of dietary patterns in the studied population and the respondents’ sex. The results of the study indicate a need for more intense nutritional education among primary school pupils, diversified for boys and girls.

Aerobic respiration and oxygen consumption are indicators of routine metabolic rate, and dissolved oxygen in plant tissues is one of the most important environmental factors affecting their survival. The reduction of available O2 leads to hypoxia which causes a limitation of the oxidative phosphorylation; when O2 is absent, tissues generate ATP by activating the fermentative glycolysis to sustain glycolysis in the absence of mitochondrial respiration, which results in the production of lactate. Overall, hypoxia was reported to often decrease the respiration rate (O2 uptake) and delay the climacteric rise of ethylene in climacteric fruits by inhibiting action, thus delaying their ripening. Much research has been done on the application of postharvest hypoxia and anoxia treatment to temperate fresh crops (controlled or modified atmosphere), however, very few reported on tropical commodities. Indeed, the physiological mode of action of low or absence of oxygen in fresh crops is not well understood; and the physiological and biochemical bases of the effects low or absence of O2 are also yet to be clarified. Recent investigations using omics technologies, however, have provided useful information on the response of fresh fruits and vegetables to this abiotic stress. The aims of this review are to (i) report on the oxygen exchange in the crops tissue, (ii) discuss the metabolic responses to hypoxia and anoxia, and (iii) report the physiological and biochemical responses of crops tissues to these abiotic stresses and the potential benefits of these environmental conditions.

Abstract Background First-year university students are exposed to different factors affecting their lifestyle. The aim of the study was to evaluate the trends in health behaviour of first-year students from four Kaunas universities over 17 years. Methods The study was carried out in 2000, 2010 and 2017. In total, 689, 739 and 1062 randomly selected first-year students participated (response rates >90%). During the lectures, participants filled in the anonymous questionnaire that included information on nutrition, physical activity, harmful habits, height, and weight. Results The reduction in daily smoking was observed: from 30.2% in 2000 to 18.4% in 2017 among males and from 21.1% to 15.9% among females, respectively. The proportion of male students drinking alcohol at least once a week declined from 62.7% in 2000 to 31.6% in 2017 and the proportion of females - from 41.5% to 27.3%, respectively. There was an increase in the proportion of students who have tried or are taking drugs: from 15.9% in 2000 to 27.8% in 2017 among males and from 4.8% to 18.8% among females, respectively. The changes in the nutrition habits of the students were observed: the proportion of students who consumed red meat every day decreased (up to 35.6% in 2017). In 2017, more students consumed cereals, fresh fruits and vegetables every day and fewer sweets, confectionery and soft drinks at least once a week than in 2000. There was a decline in meantime students spent sitting as well as in the average duration of the sleep. The proportion of students who take part in sports activities has increased by 17.1%. However, the prevalence of overweight and obesity increased from 11.7% in 2000 to 23.7% in 2017 among males, and from 4.2% to 9.0% among females, respectively. Conclusions Over 17 years, most health behaviours of the first-year students have changed in a positive direction; however, some unhealthy habits are still common and the prevalence of overweight has increased. Key messages This study highlights the importance of implementing preventive programmes among students after starting university. Monitoring of changes in health behaviour of students helps timely respond to the challenges.

ABSTRACTAlthough fruits and vegetables, sources of carotenoids, are widely available in Brazil, hypovitaminosis A constitutes a serious public health problem. There is lack of information available to the population about the dietary sources of carotenoids and factors affecting their bioavailability.The carotenoids also known as bioactive compounds have been associated with the reduction of the risk for degenerative diseases, such as cancer (modulators of immunological responses), cardiovascular diseases, macular degeneration and cataract.In Brazil the utilization of buriti fruit is not widespread; it is consumed only by the local population of some parts of the North and Central regions. Among those foods, out the foods of buritizeiro, the buriti has the highest content of β-carotene among the numerous foods already analyzed, as well as a source of oleic fatty acid, similar to olive oil.The buriti fruit provides the needs of DRI.s (Dietary Reference Intake) of vitamin A for adult, being a good source of nutrition, knowing the variety of foods that composes a balanced diet. Also, the buriti fruit is a natural source of β-carotene (provitamin A). Also, it has antioxidant power by having carotenoids, polyphenols, vitamin C compared to other vegetables, can be considered a functional food.

Microbial spoilage is one of the main factors affecting the quality of fresh fruits and vegetables, leading to off-flavor, fermented aroma, and tissue decay. The knowledge of microbial growth kinetics is essential for estimating a correct risk assessment associated with consuming raw vegetables and better managing the development of spoilage microorganisms. This study shows, for the first time, that only a part of total microbial community, originally present on fresh harvested female zucchini flowers, was able to adapt itself to refrigerated conditions. Through the study of microbial growth kinetics it was possible to isolate forty-four strains belonging to twenty-two species of the generaAcinetobacter, Arthrobacter, Bacillus, Enterobacter, Erwinia, Klebsiella, Pantoea, Pseudoclavibacter, Pseudomonas, Serratia, Staphylococcus,andWeissella, suggestingEnterobacteriaceaeas potentially responsible for pistil spoilage.

Pulping machines are an integral part of production lines for the processing fruits and vegetables. To meet the ever-growing demand for these agricultural products, it is necessary to introduce innovative solutions to modernize equipment not only for increasing its productivity but also for ensuring its safety. The article proposes a pulping machine that helps to increase the productivity by using the entire area of the sieve drum. The productivity also depends on reliable and safe equipment operation, elimination of downtime during product pulping. One of the main factors affecting the reliable and safe operation is the pressure of pulped product on the walls of the sieve drum, and this pressure depends on the product density. It has been experimentally shown that the density of pulped product can vary significantly even for different varieties of vegetable marrow. As the calculations show, in this case the pressure inside the sieve drum of the pulping machine changes considerably (more than 10%). Therefore, the density of the product should be taken into account when calculating the design parameters of the pulping machine; it helps to ensure its reliable and safe operation and hence to reduce the probability of downtime and to improve the productivity.
