Chemical Composition and Bioactivity of Dill Seed ( L.) Essential Oil from Plants Grown under Shading.

This study determined the content and composition of dill seed ( L.) essential oil under varying light conditions: non-shaded plants in open fields and plants covered with pearl shade nets (40% shade index). Essential oil was extracted using Clevenger hydrodistillation.

Fruit and Vegetable Consumption during the COVID-19 Lockdown in Serbia: An Online Survey.

The global impact of the COVID-19 pandemic has significantly influenced individuals' dietary choices and food-buying behavior. Present research specifically delves into the alterations in fruit and vegetable (F&V) consumption among consumers in Serbia during the pandemic. The study employs an extended model of the theory of planned behavior (TPB), incorporating the construct of consumers' knowledge to comprehensively explore behavioral changes.

Comparative Study of the Nutritional and Chemical Composition of New Oil Rape, Safflower and Mustard Seed Varieties Developed and Grown in Serbia.

Oilseed crops are widely cultivated and are related to nutrition and human health as valuable nutraceutical sources with valuable biological properties. The growing demand for oil plants used in human and animal nutrition or for the processing industry has contributed to the diversification and development of a new variety of oil crops. Increased oil crop diversity, besides ensuring reduced sensitivity to pests and climate conditions, has also led to improved nutritional values.

Emerging Perspectives of Blockchains in Food Supply Chain Traceability Based on Patent Analysis.

In the field of blockchain (BC) technology application in the food supply chain (FSC), a patent portfolio is collected, described, and analyzed using Latent Dirichlet Allocation (LDA) modeling, with the aim of obtaining insight into technology trends in this emerging and promising field. A patent portfolio consisting of 82 documents was extracted from patent databases using PatSnap software. The analysis of latent topics using LDA indicates that inventions related to the application of BCs in FSCs are patented in four key areas: (A) BC-supported tracing and tracking in FSCs; (B) devices and methods supporting application of BCs in FSCs; (C) combining BCs and other ICT technologies in FSC; and (D) BC-supported trading in FSCs.

Effect of shading and grafting on yield and quality of tomato.

Background: The need to increase marketable tomato yields and decrease losses due to sunburn and disease during the summer motivates farmers to adopt additional cultural practices such as shading and grafting. To investigate complex interactions among grafting, shading, and tomato cultivar, grafted and ungrafted tomatoes (cv. 'Optima' F and cv.

Physicochemical properties and mineral content of honey samples from Vojvodina (Republic of Serbia).

Forty-five honey samples of three honey types - two monofloral (acacia and sunflower) and one polyfloral (meadow) were collected from the Autonomous Province of Vojvodina (Republic of Serbia) and analysed for their physicochemical parameters (moisture, acidity, pH, ash, electrical conductivity, glucose, fructose, hydroxymethylfurfural (HMF), CIE Lab colour and mineral content). All tested physicochemical parameters were in agreement with the EU regulation except for moisture (4 samples) and HMF content (1 sample). Principal component analysis (PCA) was used for assessing the effects of three honey types on all investigated physicochemical parameters.

Effects of high temperatures and drought during anthesis and grain filling period on wheat processing quality and underlying gluten structural changes.

Background: Climate changes do not only affect wheat yield, but also its quality. Information on this topic gathered so far is somewhat contradictory and insufficient. Climate changes also affect wheat indirectly through their influence on the ecosystem, including insects and fungi that affect wheat technological quality.

The optimisation of traditional fermentation process of white cabbage (in relation to biogenic amines and polyamines content and microbiological profile).

White cabbage heads cultivar "Futoški" and hybrid "Bravo" were investigated during fermentation process, for 50days, at different temperature regimes (16-18; 18-20; 20-22°C) and salt concentrations 1, 1.5 and 2%. The quantity of biogenic amines (tryptamine, phenylethylamine, putrescine, cadaverine, histamine, serotonine, tyramine, spermidine and spermine), as well as microbiological profile (lactic acid bacteria, total number of microorganisms, yeasts and moulds and Enterobacteriaceae) have been determined during fermentation.

Effects of wheat bug (Eurygaster spp. and Aelia spp.) infestation in preharvest period on wheat technological quality and gluten composition.

The effects of wheat bug infestation (Eurygaster spp. and Aelia spp.) on the composition of wheat gluten proteins and its influence on flour technological quality were investigated in the present study.

Effect of different ripening conditions on pigments of pepper for paprika production at green stage of maturity.

The content and composition of pigments and CIELab color properties in fruits ripened in the field were compared with those obtained in ground paprika produced from green pepper fruits after postharvest ripening for 15 days in a greenhouse under different conditions. Obtained data for pigment content, composition, and esterification rate have shown that the processes of pigment biosynthesis in fruits ripened under greenhouse conditions are different from those occurring in fruits naturally matured in the field: the red/yellow pigment ratio (3:1) in greenhouse-ripened fruits is much higher than in naturally ripened pepper in breaker (1:1) and also in faint red (2:1) ripening stages from the field. Additionally, during the postharvest ripening of green pepper in the greenhouse esterification processes are less expressed than during the ripening of the fruits in the field.

Adsorption of heavy metals from electroplating wastewater by wood sawdust.

Poplar wood sawdust was examined for adsorption as a replacement for current, more expensive methods of removing copper, zinc and cadmium from electroplating wastewater. Langmuir, Freundlich, BET and competitive Langmuir (two competing ions) isotherms were fitted to experimental data and the goodness of their fit for adsorption was compared. The shapes of isotherms obtained fitted well with multilayer adsorption.
