Quality and Oral Processing Characteristics of Traditional Serbian Ćevap Influenced by Game Meat

This study analyzes the influence of two different types of game meat (deer and wild boar) in relation to quality characteristics and oral processing attributes of skinless sausage. The goal of this study was to compare grilled game-meat-based “ćevap” with conventional pork-meat-based samples. Research comprised of color analysis, evaluation of textural components, testing degree of difference, temporal dominance of sensations, calculation of main oral processing attributes, and examination of particle size distribution. The results show that oral processing attributes are similar in between samples and concur with results of the pork-based sample. This confirms the working hypothesis that it is possible to make game-meat-based “ćevap” fully comparable with conventional pork meat products. In parallel, color and flavor characteristics are influenced by the type of game meat in the sample. Most of the dominant sensory attributes that occurred during mastication were game meat flavor and juiciness. © 2023 by the authors

DEFICIT IRRIGATION TECHNIQUE FOR REDUCING WATER USE OF TOMATO UNDER POLYTUNNEL CONDITIONS

The aim of paper was to asses the use of regulated deficit irrigation (RDI) for production of two tomato cultivars (Cedrico and Abellus) in polytunnels in Serbia. RDI plants received 60% of the water that was applied to FI plants and significant saving of water for irrigation and increased in irrigation water use efficiency (IWUE) were achieved. Yield data for Cedrico cultivar showed no differences between RDI and FI, while due to the bigger sensitivity to drought, yield of Abellus was reduced under RDI. In general, fruit quality (soluble solids, titrable acidity) was sustained or improved in both cultivars under RDI. Economic analyses showed that due to the current low prices of water and electricity in Serbia, the profit increase of Cedrico, similarly to the previously trialed cultivar Amati, was not high under RDI comparing to FI. Reduction of yield and consequent profit for Abellus, indicated that for future commercial growing of tomato under RDI should be used drought resistant cultivars

Modelling and enhancement of organizational resilience potential in process industry SMEs

The business environment is rapidly changing and puts pressure on enterprises to find effective ways to survive and develop. Since it is almost impossible to identify the multitude of complex conditions and business risks, an organization has to build its resilience in order to be able to overcome issues and achieve long term sustainability. This paper contributes by establishing a two-step model for assessment and enhancement of organizational resilience potential oriented towards Small and Medium Enterprises (SMEs) in the process industry. Using a dynamic modelling technique and statistical tools, a sample of 120 SMEs in Serbia has been developed as a testing base, and one randomly selected enterprise was used for model testing and verification. Uncertainties regarding the relative importance of organizational resilience potential factors (ORPFs) and their value at each level of business are described by pre-defined linguistic expressions. The calculation of the relative importance of ORPFs for each business level is stated as a fuzzy group decision making problem. First, the weighted ORPFs’ values and resilience potential at each business level are determined. In the second step, near optimal enhancement of ORPFs’ values is achieved by applying a genetic algorithm (GA).Research presented in this paper was supported by Ministry of Science and Technological Development of Republic of Serbia, Grant No 35033, Title: Sustainable development technology and equipment for the recycling of motor vehicles.info:eu-repo/semantics/publishedVersio

In vitro i in vivo efekti Pseudomonas spp. i Bacillus sp. na Fusarium acuminatum, Botrytis cinerea i Aspergillus niger na krastavcu

Cucumber (Cucumis sativus L) is an important member of the Cucurbitaceae family. Production of healthy nursery is necessary for high-quality production of this crop in greenhouses and in fields. With the idea of minimizing the use of pesticides and mineral fertilizers to preserve soil quality, we investigated the effects of plant growth promoting bacteria (PGPB) on growth promotion and protection of cucumber plants from phytopathogenic fungi. The effects of Pseudomonas spp. strains with different antifungal activities and Bacillus sp. Q10 strain with PGP activity were tested on cucumber plants. Antagonistic activity of Pseudomonas spp. against the growth of several phytopathogenic fungi isolated from cucumber: F. acuminatum, B. cinerea and A. niger, was observed. The influences of overnight cultures, supernatants and heat-stable antifungal factors were tested on the phytopathogenic fungi in vitro. Pseudomonas sp. K35 and K24 strains were more effective than P. chlororaphis Q16 and Pseudomonas sp. K27, showing 70-80% of fungal growth inhibition regardless of culture or fraction applied. The good antagonists that belong to pseudomonads and Bacillus sp. Q10 strain were used as mixtures for estimation of plant growth and health promoting effects on cucumber plants. Growth dynamics differed depending on the applied strain of Pseudomonas sp. The M3 treatment (a mixture of Bacillus sp. Q10 and P. chlororaphis Q16) stimulated the initial phase of growth, while M4 (a mixture of Bacillus sp. Q10 and Pseudomonas sp. K24) resulted in the maximal height at the final measurement. Significant differences in leaf and plant weight (M4), and leaf weight (M5, containing K35 strain) were found after the treatments. No significant differences in chlorophyll and NBI level were observed in any of the tested combinations. The obtained results suggested that M3 was suitable for stimulation of the early phase of cucumber growth, while the mixtures M4 and M5 improved plant protection and stimulated the later phases of cucumber growth.Krastavac (Cucumis sativus L) je važan predstavnik familije Cucurbitaceae, a proizvodnja zdravog rasada je nephodna za visoku produktivnost u plastenicima i na otvorenom polju. Da bi se umanjila primena pesticida i mineralnih đubriva i pri tome sačuvalo zemljište, ispitan je uticaj bakterija stimulatora biljnog rasta (PGPB) na rast biljaka i zaštitu od patogena. Primenjeni su sojevi Pseudomonas spp. sa različitim antimikoznim delovanjem i Bacillus sp. soj Q10 sa PGP aktivnošću. Praćena je antagonistička aktivnost Pseudomonas spp. na fitopatogene gljive izolovane sa biljaka krastavca: F. acuminatum, B. cinerea i A. niger. Testiran je uticaj prekonoćne kulture bakterija, supernatanta i termostabilnih antifungalnih faktora na rast ovih fitopatogena. Pseudomonas sp. K35 i K24 sojevi, koji pokazuju 70-80% inhibicije rasta gljiva bez obzira na primenjenu kulturu ili frakciju, efektivniji su od P. chlororaphis Q16 i Pseudomonas sp. K27. Sojevi Pseudomonas spp., koji su ispoljili visok stepen antagonizma, kombinovani su sa sojem Bacillus sp. Q10 i procenjen je uticaj na rast i zdravstveno stanje biljaka krastavca. U zavisnosti od primenjenog soja Pseudomonas sp., razlikovala se dinamika rasta krastavca. Tretman M3 - kombinacija Bacillus sp. Q10 i P. chlororaphis Q16 uticala je na početnu fazu porasta biljaka, dok je treatman M4 - kombinacija Bacillus sp. Q10 i Pseudomonas sp. K24, imala najviše uticaja na visinu biljke na kraju merenja. Uočene su značajne razlike za masu lista i masu biljke (M4) i masu lista (M5 sa sojem K35), dok sadržaj hlorofila i nivo NBI nisu imali značajne razlike kod svih ispitivanih kombinacija. Dobijeni rezultati ukazuju da je M3 pogodan za rane faze razvoja biljke, a kombinacije M4 i M5 pogodne su za zaštitu biljaka i u kasnijim fazama porasta biljaka. Potpuna ekspresija PGP svojstava za M4 i M5 može se utvrditi tek posle testiranja na siromašnim supstratima, koji će biti upoređeni sa rezultaima dobijenim na supstratima sa dovoljno hranljivih materija
