The sharp deterioration of the environmental situation in the Republic of Kazakhstan, associated with human activity and the impact of harmful factors on the environment, affected the quality of food consumed by insufficient consumption of domestic fruit and vegetable products containing vitamins, minerals of an alkaline nature, carbohydrates, vegetable proteins, pectin substances and active fiber. The problem of improving the quality of growing and processing fruits and vegetables is one of the main tasks of the food independence of the Republic of Kazakhstan. Currently, the share of large vegetable farms in the Republic of Kazakhstan is only 10%. The volume of industrial processing of fruit and vegetable crops in Kazakhstan is insignificant. The demand for domestic fruit and vegetable products in the country is met only by 35-40%, most of it is imported from countries such as Russia, Kyrgyzstan, Uzbekistan and China. There is a need for the development of organic vegetable growing in Kazakhstan and the creation of new types of domestic fruit and vegetable products containing a sufficient amount of useful and active substances that can bind and remove toxic substances and radioactive elements from the human body. The purpose of the work is to improve the technology of fruit and vegetable semi-finished products with natural spicy and aromatic additives, to develop a multi-component recipe for vegetable mixtures and a method for producing quick-frozen vegetable mixtures with high quality indicators. These studies were aimed at studying the chemical composition and functional and technological properties of vegetables and spicy - aromatic plants for the content of biogenic compounds: carbohydrates, proteins, vitamins, essential oils, minerals and other substances. The structure of plant tissues was studied and the mass fraction of moisture, dry matter, fiber, mono - and disaccharides, pectin substances, vitamin C was determined, the formulation and production technology of Assorted vegetable mixtures were developed, and quality indicators were determined.

Vegetables definitely play a great role in food composition of a human. In countries where fruit and vegetable consumption is high, there is reduced cases of cardiovascular and cancel diseases as it was shown by epidemiological data. Vegetables bear the protective properties based on antioxidant actions of such components as vitamins, flavonoids, antozian, polyphenols and microelements including selenium, zinc, and copper and so on. The applications of stimulators of growth are safe environmental methods that can be used for improvement of yield qualities. The influence of Epin, Gumats, APIONs and other growth stimulators on antioxidant and biologically active matter contents has been studied in range of vegetable crops like perennial onion, Japanese cabbage, and bell pepper and so on.

This article analyses the contribution to local development by women workers in the fruit- and vegetable-handling sector in Almería (Spain) over the last five years (2015–2019). It is a continuation of research carried out during the period 2000–2014. Using data collected through surveys and focus groups, the aim is to ascertain if the results obtained in this analysis meet the condition of sustainability, i.e., whether the improvement in working women’s quality of life has been maintained over time, and whether these beneficial effects have multiplied. The results show that women workers in the fruit- and vegetable-handling sector are satisfied with their jobs and with the company they are working for. The existence of fixed-discontinuous employment contracts facilitates greater flexibility for women in terms of balancing work and family life. This main contribution of this study lies in extrapolating the sustainability of a local development model in regard to other initiatives that aim to increase women’s empowerment in the labour market.

Abstract The aim of the study was to assess the quality of shallow groundwater on the site pens and runoff from livestock manure heaps, in three selected farms involved in animal production and vegetable crops in the area of Plateau Proszowice. The analysis mainly included water from farm wells and effluents from manure. Additionally, water from drainage ditch running nearby farms was collected, before inflow of effluent (i.e. ditch water without manure effluent) and below inflow of effluent from heap of manure (i.e. ditch water containing manure effluent). Samples of the research material were collected from April 2012 to March 2014 at monthly intervals and analysed for the content of NO3-N, NH4-N, PO4-P, K, Na and Cl. Based on the obtained results it was found that water from the farm wells near the livestock buildings and from manure storage sites, was heavily polluted by the majority of these contaminants. The highest concentration of these pollutants, except for the NO3-N, was found in manure effluent – it exceeded a few dozen to a few hundred to any standards for water quality. There was also a significant deterioration in the quality of drainage ditch water because of the penetration of contaminants into ditch water from heaps of improperly stored manure. The water of the farm wells was characterized by excessive concentrations of NO3-N which disqualified it for drinking purposes.

Monitoring the nutritional environment is important to help inform future initiatives to improve access to healthy foods. The objective was to examine the nutritional quality of lunch meals eaten at 15 worksite canteens and then to compare with results from a study conducted 10 years before. The duplicate-portion-technique with subsequent chemical analysis was used to quantify 240 customers’ lunch intake. Estimated mean energy intake was 2.1 MJ/meal (95% confidence interval (CI): 1.9 to 2.4 g/meal) and estimated energy density 599 kJ/100 g (95% CI 550 to 653 kJ/100 g). Energy density of the male participants’ meals were significantly higher compared with the female participants’ meals (+55 kJ/100 g, 95% CI: +12 to +98 kJ/100 g, p = 0.012), whereas no gender differences were found in macronutrient distribution or fruit and vegetable intake. Compared to the study conducted 10 years before several significant changes were observed, including an increase in mean estimated intake of fruit and vegetables (+38 g/meal, 95% CI: 19 to 57 g/meal, p < 0.001) and a decrease in energy density (−76 kJ/100 g, 95% CI: −115, −37 kJ/100 g, p < 0.001). In conclusion, this study suggests an equalization of gender differences in fruit and vegetable intake and a possible improvement in the nutritional quality of canteen lunch meals over a 10-year period.

Abstract BackgroundBiomass is the most dominant source of energy for both food cooking and lighting in rural parts of Ethiopia. Energy conversions are carried out in open fires using inefficient traditional stoves, results in poor quality of life due to smoking-related health outcomes, and consume a large quantity of wood. This resulted in increased costs of health and cutting trees which facilities climate change. To change the situation, improved cooking stoves (ICS) have been introduced through youth cooperatives in the study area.Objective The study examined the major sources of energy for the rural households, evaluate the health and related benefits of using improved cook stove and assessing the determinants for its adoption.MethodData were collected from 344 households using a questionnaire in supplement with interview schedule. The collected data were analyzed using both descriptive and econometric models.ResultsThe findings of the study showed that only 22.97% of the respondents adopted the ICS whereas the vast majority (67.03%) still rely on traditional stoves that are highly inefficient. The positive and significant variables in predicting the adoption of ICS were the educational level of household head (OR 1.23; CI at 95% 0.029-0.040), access to ICS (OR 5.88; CI at 95% 1.05-2.48), affordability (OR 2.31; CI at 95% 0.11-1.56) and demonstration about the stove (OR 6.74; CI at 95% 1.13-2.68). Family size (OR 0.74; CI at 95% -0.45-0.12) and Availability of firewood (OR 0.27; CI at 95% -2.00-.56) significantly and negatively affected the adoption of the ICS.ConclusionsLow adoption levels of ICS were found in the study area. This has been triggered by socio-economic, institutional, financial, and resource endowments. Therefore, it is recommended that increasing access to improved stoves, diversifying income sources, creating awareness about ICS health benefits, climate changes, and providing reasonable prices will facilitate its adoption.

The climate changes in Murfatlar vineyard in recent years consist inthe increase ofmonthly average temperatures, recorded in both cold and warm seasons, accompanied by an irregular distribution of rainfall during the year, which significantly influences the growth of grapevine, the quality and production of grapes.Six representative cultivars were studied, three for white wines: Chardonnay, Columna and Muscat Ottonel and three for red wines: Fetească Neagră, Mamaia and Cabernet Sauvignon. In the last two years (2019-2020) warm winters and very dry summers have led to the onset of budburst, almost simultaneously for all the studied cultivars, followed by a very weak growth and development of shoots (2020) and an acceleration development of phenophases, mainly berween veraison and ripening. Water stress during the vegetative period, a hygroscopicity below 60% between July and August and low vegetative apparatus influenced the growth ofthe berries, resulting small grapes, and a very low must yield in 2020.Concerning the quality of grape production, the studied cultivars achieved more sugar concentrations in berries up to 35.8 g/L (in 2019) and 36.0 g/L (in 2020), higher than the values obtained in normal years. In the conditions of a pronounced dry climate manifested in the two years of study, the productions were below the normal level, especialy in 2020, achieving much diminished productions for all cultivars, except the Mamaia cultivar. The Mamaia cultivar had a positive reaction, registering an increase of production, that exceeded the multiannual value by 20% in 2020 andby 10% in 2019, the concentration of sugars in the must being above the average value obtained in normal years, exceeding by 3% and 9%, respectively, the multiannual average. Statistical calculations were done using SPSS Statistics 17.0, using mainly the Duncan test for a degree of significance of 5%.
