Application of additive technology in the production of functional fruit juices
No full textZadnjih godina sve je veća potražnja za funkcionalnim proizvodima. Voćni sokovi predstavljaju odličnu bazu za razvoj ovakvih proizvoda obzirom da se mogu obogatiti s različitim funkcionalnim sastojcima kao što su antioksidansi, prebiotici, probiotici, višestruko nezasićene masne kiseline, fitosteroli, i drugi. S druge strane, u prehrambenoj industriji sve se više razvija i primjenjuje aditivna tehnologija, posebice 3D printanje. Primjenom 3D printanja moguće je potpuno definirati i dizajnirati funkcionalan proizvod, od sastava do konačnog oblika. Postoje različiti načini printanja hrane: na principu ekstruzije, selektivnog laserskog sinteriranja, pomoću tekućeg vezivnog sredstva i na principu tintnih pisača. Na kvalitetu konačnog proizvoda značajno utječu svojstva printera, kao i svojstva materijala. Kod printanja voćnih sokova potrebno je prvotno podesiti udio vode u soku, što se najčešće provodi dodavanjem prirodnih zgušnjivača. U ovom radu obuhvaćen je pregled rezultata najnovijih istraživanja s primjenom aditivne tehnologije u proizvodnji funkcionalne hrane s naglaskom na funkcionalne voćne sokove.Recently, there has been a growing demand for functional food products. Fruit juices are excellent for development of such products, because they can be enriched with antioxidants, prebiotics, probiotics, polyunsaturated fatty acids, phytosterols etc. Additive technology, especially 3D printing, is increasingly being developed and applied for food industry. By applying 3D printing, it is possible to fully designed functional product and assemble it to the final shape. There are different ways of printed food: on the principle of extrusion, selective laser sintering, using liquid binders and main inkjet printers. Properties of the printer, as well as the properties of the material, affect the quality of the final product. When printing fruit juices, it is necessary to adjust water contents, which is usually done by adding natural thickeners. This thesis reviews the latest research with applications of additive technology for production of functional foods with an emphasis on functional fruit juices
The influence of fatty food simulants on the value of specific and global migration in polymer packaging materials
No full textU svijetu ubrzane proizvodnje i inovacije bitno je osigurati zdravstvenu ispravnost predmeta koji dolaze u kontakt s hranom. Globalna i specifična migracija su pojave koje se stalno događaju te ih je bitno konstantno motriti kako bi se mogli donijeti zaključi o interakciji ambalaže s hranom. U ovom radu proučavana je specifična i globalna migracija iz 20 polimernih folija. Ispitivana je globalna migracija u simulantu hrane modificiranom poli(2,6-difenil-fenilen oksidu) (TENAX®-u) kao i u modelnim otopinama biljnog ulja, etanola i octene kiseline. Osim toga, proučavana je i specifična migracija 8 organskih spojeva i 18 metala. Vrijednosti migracije su uspoređene s obzirom na zahtjeve iz Uredbe Europske unije 10/2011. Svih 20 analiziranih folija je imalo vrijednost globalne i specifične migracije manje od propisane prema uredbi 10/2011.In the world of accelerated production and innovation, it is essential to ensure the healthiness of items that come into contact with food. Global and specific migration are phenomens that constantly occur, and it is important to observe them to be able to draw conclusions about the interaction of packaging with food. In this work, the specific and global migration from 20 polymer foils was studied. Global migration in poly (2,6-diphenilen oxide) TENAX®, vegetable oil, ethanol and acetic acid was investigated. In addition, the specific migration of 8 organic compounds and 18 metals is studied. The migration values were compared regarding the requirements of the European Union Regulation 10/2011. All 20 foils had a value of global and specific migration less than prescribed according to regulation 10/2011
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
