The combined necessity for sustainable production, a decrease in the human impact on the environment, the European Union striving to be climate neutral, and the pressure on the food industry to introduce sustainable technologies and products and reduce emissions into the environment to the minimum has led to perceiving food industry by-products (FIB) as valuable raw materials rather than waste. This has driven a constant increase in scientific research regarding the use of FIB. The aim of this research was to establish focal points and directions of the scientific research regarding FIB. Descriptive bibliography and visualization using software CiteSpace II were used to analyze research published in journals indexed in the Web of Science Core Collection and determine and explain development trends. The results showed a constant growth of the scientific interest for FIB, which intensified since 2015. Research is being conducted worldwide, with Spain (13%) and Italy (11%) as leading countries. The results are published in journals with high impact factors and quartiles, using references published in the same rank.

The growing demand for healthier food options has accelerated the development of innovative fat-replacement strategies in spreadable products. Oleogels are semi-solid systems formed by structuring edible oils. Recently, these systems have emerged as a promising solution for reducing saturated fat content without compromising product quality, texture, or sensory attributes. A systematic review was conducted following the PRISMA 2020 protocol, supplemented by a bibliometric analysis. Research was identified through searches in Web of Science, Scopus, Wiley, Springer, MDPI, and Google Scholar for studies published between 2020 and 2024. Inclusion criteria focused on original research articles in English involving food-sector applications of oleogels and aerogels in sweet spreads. Study quality and risk of bias were assessed by two independent reviewers based on methodological relevance and data integrity. Results were synthesized through a narrative approach and bibliometric mapping. After screening 490 records, 34 original research articles were included. Bibliometric data highlighted a clear trend shifting from foundational lipid structuring research in 2020 toward complex, product-specific functional applications by 2024. Overall, the results suggest that these structured systems are viable replacements for traditional saturated fats, providing comparable spreadability and stability. Funding: This work was supported by the Croatian Science Foundation under the project IP-2022-10-1960. This systematic review was not registered in a public database.

The search for alternative fuels led to the development of biodiesel research. However, in order for biodiesel to meet the prescribed standards, it must first fulfil the proportion of fatty acid methyl esters (FAME) in its composition. Among several possible methods for the determination of FAME, the standard prescribes the use of gas chromatography (GC). The aim of this study was to provide an overview of the international literature dealing with this topic over the last five years. To achieve this goal, a search of the Web of Science database (WoS) was carried out, followed by a bibliometric analysis in the VOSviewer software. The analysis included 99 studies published over the last five years. The main authors, countries, institutions, journals and keywords were identified to highlight important contributions in the field. The scientific mapping revealed collaborative networks and research focus areas such as analysis, catalysts, conversion, yield, biomass, but also biodiesel production itself. The review showed that this research is carried out by scientists from different scientific categories linked by this highly topical issue in total link strength of 273.

U radu je prema bibliometrijskim pokazateljima analiziran časopis Mathematical Communications u razdoblju od 1996. do 2015. godine. U razdoblju od dvadeset godina, od prvog do dvadesetog godišta 2015. godine, uzorak čine 582 rada. Cilj istraživanja bio je utvrditi je li vidljivost časopisa porasla otkako je časopis indeksiran u bazama podataka Web of Science Core Collection (WoSCC) i Scopus. Rezultati istraživanja pokazali su da je, nakon što je časopis indeksiran u bazama podataka WoSCC i Scopus, broj radova u pojedinom godištu, a sukladno tomu i broj stranica, značajno porastao, da se u njemu gotovo isključivo objavljuju izvorni znanstveni radovi, da je broj inozemnih autora povećan, da je povećan broj referenci na koje autori upućuju, a koji se u zna- čajnom broju odnose na strane časopise i knjige te da broj referenci koje se odnose na radove objavljene u časopisu MC nije velik. Osim toga, značajno je porasla citiranost radova u bazama WoSCC i Scopus, a primjećuju se i pozitivni pomaci pri rangiranju časopisa u izvješćima o citiranosti časopisa JCR (Journal Citation Report) i SCImago Journal & Country Rank. Sustavnim radom i uređivačkom politikom u publiciranju radova uredničkoga od- bora MC je postao prepoznatljiv i prihvaćen časopis u području matematike.

U ovom radu prikazana je produktivnost autora Sveučilišta Josipa Jurja Strossmayera u Osijeku za razdoblje od 2011. do 2015. godine upotrebom bibliometrijskih pokazatelja kroz skup baza podataka Web of Science Core Collection (WoS CC). U analizi su kao osnova uzeti u obzir svi rezultati dobiveni pretragom po adresi Sveučilišta i svake pojedine sastavnice Sveučilišta. Analiza je napravljena prema određenim bibliometrijskim pokazateljima: broju objavljenih radova po sastavnici, njihovoj citiranosti te po h-indeksu sastavnice za navedeno razdoblje, broju objavljenih radova u pojedinoj godini, vrsti dokumenta, znanstvenom području koje pokriva pojedina WoS CC-kategorija, broju radova objavljenih u hrvatskim ili inozemnim časopisima, broju radova objavljenih u zbornicima radova koji su indeksirani u WoS CC te po kvartilu časopisa.
