51. Učinek menjave embalaže izdelkov izbranega podjetjaSara Vodopivec, 2014, undergraduate thesis Abstract: V podjetju dajejo vedno večji poudarek pospeševanju prodaje in marketingu ter temu primerno namenjajo tudi vedno več denarnih sredstev. Danes ni več najpomembneje, kakšen izdelek prodajaš, temveč le, ali ga znaš prodati. Vedno bolj postaja pomemben tudi videz embalaže in ne samo izdelek, ki je v njej. Embalaža mora biti privlačna za kupca in ga mora pritegniti ter privabiti v nakup. V diplomskem delu smo predstavili pospeševanje prodaje, pomen embalaže, podjetje Fructal in njegove izdelke, menjavo embalaže dvema izdelkoma ter učinek te menjave. Skozi teoretični del smo na kratko predstavili pospeševanje prodaje ter osnovne funkcije embalaže. Poleg tega teoretični del opisuje zgodovino, pomen, orodja in cilje pospeševanja prodaje ter pomen, funkcijo in kriterije ocenjevanja embalaže. V analitičnem delu pa smo analizirali menjavo embalaže dvema izdelkoma in navedli nekaj lastnih predlogov za izboljšanje. Z analizo podjetja Fructal in njegove menjave embalaže izdelkoma Fructal Classic in Smoothie smo prišli do sklepov in ugotovitev, ki bi morda pomagali podjetju. Na splošno je bila menjava embalaže izdelka Classic dobro ocenjena, medtem ko je bila menjava embalaže izdelku Smoothie slabše ocenjena. Menimo, da bi moralo podjetje Fructal v spremembe bolj vključiti potrošnike in jim te še bolje skomunicirati in približati.

52. Identification of sweet cherry anthocyanins and hydroxycinnamic acids using HPLC coupled with DAD and MS detectorPolonca Trebše, Branka Mozetič Vodopivec, 2004, original scientific article Abstract: In absence of standards, HPLC coupled with DAD offers identification of polyphenols by scanning UV-Vis spectra of individual components, which spectral characteristics are unique, but not selective. At the same time HPLC-DAD determination methods of polyphenols differ in mobile phase solutions resulting in DAD scanned spectra deviation between different studies, aggravating the precise identification based on agreement to UV-Vis data from literature. Mass spectrometry (MS) detection with molar weight determination of the individual components in the sample enables more precise identification of compounds eluted from the column. Sweet cherry Petrovka polyphenols were separated on C18 Hypersil PEP 300 column (250 x 4.6 mm, 5 [mu]m) using gradient solvent mixture consisting of methanol, water and formic acid. MS and UV-Vis spectra of eluted anthocyanins and hydroxycinnamic acid were recorded. HPLC-MS analyses were performed using a LCQ [sup]TM ion trap, Finnigan, MAT mass spectrometer by atmospheric pressure chemical ionisation (ACPI). Molecular and fragmented ion masses of sweet cherry hydroxycinnamic acids and anthocyanins were determined and with UV-Vis spectra, in the range of 190-600 nm, used for identification of compounds. Electro spray mass spectrum of two hydroxycinnamic acids produced ions with m/z ratios of 353.0 and 337.0, which corresponded to molecular weights of neochlorogenic acid and 3'-p-coumarylquinic acid. The molecular weights of 5 anthocyanins corresponded to cyanidin-3-glucoside (449.0), cyanidin-3-rutinoside (595.1), peonidin-3-glucoside (463.1), pelargonidin-3-rutinoside (579.1) and peonidin-3-rlltinoside (609.2).
