    Food industry is craving to develop new technologies and processes which will satisfy customers’ ambiguous wishes but also specific dietary needs. In 21st century, food allergies or food intolerances are affecting population from nurseries up to elderly stages while causing people, not only health issues but also making their nutrition plans and grocery shopping challenging and expensive. Three dimensional (3DP) food printing is a potential solution to advance current food processing techniques, but also to integrate 3DP and digital gastronomy technique to customize food products. If applied in domestic cooking or catering services, 3DP can provide an engineering solution for customized food design and personalized nutrition control, but also has the potential to redefine food supply chains. Still, people might be doubtful to eat 3D printed food due to their perception that it does not taste as good as traditional food and it appeals almost over-processed and artificial. This paper gives the short overview on 3DP techniques, devices and ingredients used for 3DP, as well as the possible future application in food manufacturing

    The aim of this work was to investigate the effect of high voltage electrical discharge (HVED) plasma on inactivation of Brettanomyces bruxellensis yeast in red wine. Research was conducted in two phases. Firstly, the efficacy of two main plasma parameters was examined - frequency (60, 90 and 120 Hz) and treatment duration (3, 5, 10, 20 and 30 min). Second phase included monitoring long-term effect of HVED plasma using optimal frequency during selected treatment durations, where culturability of B. bruxellensis was determined after 30, 60 and 90 days of storage. Results show that frequency of 120 Hz caused slightly higher inactivation than the lower ones. Furthermore, longer treatment durations resulted in significantly higher inactivation, wherein the treatment of 30 min showed the best results. Finally, during storage period, the inactivation effect of HVED plasma was reversed and B. bruxellensis yeast recovered almost completely in treated wine.Cilj ovog istraživanja bio je utvrditi utjecaj visokonaponskog električnog pražnjenja - hladne plazme na inaktivaciju kvasca Brettanomyces bruxellensis u crnom vinu. Istraživanje je provedeno u dvije faze. U prvoj fazi je istražena učinkovitost dva glavna procesna parametra - frekvencije (60, 90 i 120 Hz) i trajanja tretmana (3, 5, 10, 20 i 30 min). Druga faza je obuhvatila praćenje dugoročnog učinka hladne plazme, uz primjenu optimalne frekvencije tijekom različitih vremena tretiranja pri čemu je prisutna populacija kvasca B. bruxellensis utvrđena praćenjem rasta kolonija kvasca na selektivnoj podlozi nakon 30, 60 i 90 dana skladištenja. Utvrđeno je kako je primjena frekvencije od 120 Hz rezultirala blago povećanom inaktivacijom kvasca B. bruxellensis u usporedbi s primjenom nižih frekvencija. Nadalje, duža vremena tretiranja rezultirala su značajnijom inaktivacijom, pri čemu se tretman u trajanju od 30 min ističe kao najbolji. Tijekom skladištenja uočeno je obnavljanje rasta populacije kvasca B. bruxellensis prisutne u crnom vinu odnosno smanjenje inaktivacijskog učinka tretmana hladnom plazmom

    Research background. Two methods of milk treatment were used, ultrasound (innovative method) and bactofugation, after which the physicochemical and sensory properties of the milk were examined, with the primary aim of achieving the quality and consistency of the pasteurized milk. Experimental approach. Ultrasound power of 200 and 400 W and frequency of 24 kHz with constant wave cycle were used. Milk was treated for 2.5, 5, 7.5 and 10 min with sonification at 20 °C (room temperature) and thermosonification (ultrasound at temperature higher than room temperature) at 55 °C. The purpose of this study is to investigate the effect of high-power ultrasound combined with a slightly increased temperature on whole, skimmed and skimmed cow’s milk pretreated with bactofugation. Results and conclusions. The best sensory quality was achieved when milk was treated with ultrasound power of 200 W at 20 °C for max. 7.5 min. This research shows the potential of the applications of high-power ultrasound in dairy industry combined with bactofugation as a pre-treatment of milk at a slightly increased temperature (up to 55 °C). Novelty and scientific contribution. The application of these two treatments requires milder processing conditions than pasteurization, it is economical and more environmentally friendly technological process that preserves better nutritional values of milk, which is preferred by consumers.Pozadina istraživanja. Primjenjene su dvije metode obrade mlijeka: ultrazvuk (inovativna metoda) i baktofugiranje, nakon čega su ispitana fizikalno-kemijska i senzorska svojstva mlijeka, s osnovnom svrhom postizanja kakvoće i konzistencije pasteriziranog mlijeka. Eksperimentalni pristup. Korištena je snaga ultrazvuka od 200 i 400 W pri frekvenciji od 24 kHz s konstantnim valnim ciklusom. Mlijeko je tretirano sonifikacijom tijekom 2,5; 5; 7,5 i 10 min na 20 °C (sobnoj temperaturi) i termosonifikacijom (primjenom ultrazvuka na temperaturi višoj od sobne temperature) na 55 °C. Svrha je ove studije bila istražiti učinak ultrazvuka velike snage u kombinaciji s djelomično povišenom temperaturom na sirovo punomasno, obrano i obrano kravlje mlijeko prethodno obrađeno baktofugiranjem. Rezultati i zaključci. Najbolja senzorska kakvoća postignuta je obradom mlijeka ultrazvukom snage od 200 W pri 20 °C, tijekom maksimalno 7,5 min. Ovo istraživanje pokazuje potencijal primjene ultrazvuka velike snage u mljekarskoj industriji u kombinaciji s baktofugiranjem kao postupkom prethodne obrade mlijeka na djelomično povišenoj temperaturi (do 55 °C). Novina i znanstveni doprinos. Tijekom primjene ova dva postupka prerade mlijeka koriste se blaži uvjeti obrade od pasterizacije, pa se mogu smatrati ekonomičnim i ekološki prihvatljivijim tehnološkim postupcima, pomoću kojih se može bolje očuvati hranjiva vrijednost mlijeka, a što preferiraju i potrošači

    High voltage electrical discharge (HVED) plasma processing receives more and more attention due to its potential to assure microbial safety and retain quality of treated products. The influence of combined thermal and high voltage electrical discharge plasma treatment on apple juice quality was investigated. Apple juice samples were treated under defined plasma treatment parameters of time (3, 6 and 9 min), frequency (60, 90 and 120 Hz) and temperature (30, 40 and 50 oC) in hybrid plasma reactor. Prior to treatment, juice samples were inoculated with Saccharomyces cerevisiae ATCC 204508 to investigate inactivation possibilities of plasma treatment on yeasts as common juice microorganisms. Quality parameters (pH, electrical conductivity, phenolic content and antioxidant activity) of treated and untreated apple juice were investigated and compared. Results have shown effectiveness of HVED plasma treatment in yeast inactivation up to 6.6 log10 in 9 min of treatment at 120 Hz and temperature of 40 oC. In treated samples there were no significant changes in phenolic content

    Ultrasonication is a nonthermal food processing method that is used in several applications (extraction, treatment before drying, freezing, inactivation of microorganisms, etc.) in ultrasound processing. The objective of this study is to investigate the effect of high power ultrasound and pasteurisation on the aroma profile and sensory properties of apple juice and nectar. Samples were treated according to the experimental design, with high power sonicator at ultrasound frequency of 20 kHz under various conditions (treatment time: 3, 6 and 9 min, sample temperature: 20, 40 and 60 °C, and amplitude: 60, 90 and 120 μm). The aromatic profiles of juices showed that, compared to the untreated samples of juices and nectars, ultrasonic treatment led to the formation of new compounds (which were not present in the untreated samples) or to the disappearance of compounds that were found in the untreated samples. Samples treated at the highest amplitude (120 μm) were used for evaluation and comparison with untreated and pasteurised samples using electronic tongue study. Principal component analysis confirmed the results of electronic tongue study, which showed that the ultrasound-treated and pasteurised juices had different scores compared to the untreated samples

Svrha je ovoga rada bila istražiti utjecaj ultrazvuka velike snage, te postupka pasterizacije na aromatski profil i senzorska svojstva jabučnog soka i nektara. Uzorci su obrađeni ultrazvukom velike snage i niske frekvencije od 20 kHz pri različitim uvjetima (vrijeme tretmana: 3, 6 i 9 min; temperatura: 20, 40 i 60 °C i amplituda: 60, 90 i 120 μm). Iz aromatskog se profila jabučnog soka i nektara može zaključiti da je nakon obrade ultrazvukom došlo do nastanka novih spojeva, a istodobno i do razgradnje nekih spojeva koji su pronađeni u netretiranim uzorcima. Uzorci izloženi ultrazvučnim valovima najveće amplitude (120 μm) uspoređeni su s netretiranim i pasteriziranim uzorcima pomoću elektroničkog jezika. Analizom osnovnih komponenata (engl. principal component analysis - PCA) utvrđeno je da uzorci obrađeni ultrazvukom i pasterizirani sokovi imaju drukčije vrijednosti od netretiranih sokova, što je potvrđeno i senzorskom analizom
