Abstract

Napitak od kombuche predstavlja popularni napitak od fermentiranog čaja, funkcionalnu namirnicu s raznim dobrobitima poput antibakterijskog i antioksidativnog svojstva te podupiranja imunosnog sustava i metabolizma. Dobrobiti kombucha napitka kriju se u bioaktivnim komponenama koje sadrži, a one uključuju aminokiseline, vitamine, polifenole, vlakna i organske kiseline. Među njima, prisutni su i važni biogeni elementi kao što su željezo, mangan i cink. Ti elementi neophodan su dio enzima ključnih u održavanju različitih biokemijskih procesa u organizmu, stoga je njihova dnevna konzumacija važna za optimalno zdravlje čovjeka. Zbog načina proizvodnje i vrste početnih sastojaka korištenih u proizvodnji, kombucha napitci su po svome sastavu raznoliki. U ovome radu prvi su se puta tehnikom masene spektrometrije s induktivno spregnutom plazmom (ICP-MS) analizirali minerali kalcija, željeza, magnezija, cinka i mangana u pet različitih uzoraka kombucha napitka, od kojih je jedan bio kontrolni uzorak. Analiza uzoraka omogućila je praćenje promjena koncentracija minerala u svakome uzorku te uvid u utjecaj različitih dodataka u uzorcima na koncentraciju samih minerala.

Abstract (english)

Kombucha drink is a popular drink made of fermented tea. This functional food has various health benefits including antibacterial and antioxidant properties and a role in supporting the immune system and metabolism. The benefits of the kombucha drink are founded on the bioactive components it contains, which include amino acids, vitamins, polyphenols, fibers, and organic acids. Among them, important biogenic elements such as iron, manganese, and zinc are also present. As a functional part of various enzymes, these elements are crucial in maintaining various biochemical processes in the body, therefore their daily consumption is important for optimal human health. Kombucha drinks are diverse in their composition due to differences in the production method and the type of used ingredients. In this paper, the minerals calcium, iron, magnesium, zinc, and manganese were, for the first time, analyzed with the inductively coupled plasma mass spectrometry method (ICP-MS) in five different samples of a kombucha drink, one of which was used as a control sample. The sample analysis enabled the monitoring of the change in mineral concentrations in each sample and observing the influence of different additives in the samples on the concentration of the minerals themselves.
