Določanje želatine v papirju

Pačnik, Nejc (author), Strlič, Matija (mentor)

V raziskovalni nalogi bom napravil pregled literature za kvantitativno določanje beljakovin v vzorcih naravnega izvora. V ta namen se uporabljajo različne metode, od spektrofotometričnih do kromatografskih. Prve zahtevajo reakcijo, ki vodi do nastanka obarvane spojine, kromatografske metode pa večinoma zahtevajo razklop do aminokislin. Med beljakovinskimi dodatki v papirju najdemo izključno želatino, kot dodatek, ki naredi površino hidrofobno. V kolikor bodo pogoji to omogočali, bom opravil analizo vsebnosti želatine v vzorcih tibetanskega izvora.

• Title: Determination of gelatin in paper

Abstract

In this research, I will review the literature for the quantitative determination of proteins in samples of natural origin. Various methods are used for this purpose, from spectrophotometric to chromatographic. The former require a reaction leading to the formation of a colored compound, and chromatographic methods mostly require cleavage to amino acids. Among the protein additives in paper, we find exclusively gelatin, as an additive that makes the surface hydrophobic. If conditions allow, I will perform an analysis of the gelatin content in samples of Tibetan origin.
