Rezime
U ovom radu je ispitivan uticaj materijala ambalaže na pH vrednost vina
tokom vremena. Uzorak vina je raspodelje u tri vrste ambalaže: staklenu, plastičnu
PET i tetrapak, a zatim je duži vremenski period pradena vrednost pH. Najbolje
rezultate, tj. najsporiji pad pH pokazao je uzorak u tetrapak ambalaži.
Ključne reči: pH vrednost vina, staklena ambalaža, PET ambalaža, tetrapak.
Abstract
The dependence of the vine pH value on the beverage material was
investigated in respect of time. The sample of the vine was separated in the three
kind of beverage: glass, PET and Tetra Pack. The Tetra pack have been shown the
best results, the slowest foling of pH value.
Key words: vine pH value, glass beverage, PET beverage, Tetra Pack
