Crosslinking of Gelatin with Formaldehyde; a 13C NMR Study
نویسندگان
چکیده
The different species formed when gaseous formaldehyde is dissolved in aqueous medium are investigated by a l3C NM R flow-through technique and the spectra of commercial aqueous form aldehyde solutions containing methanol com pletely interpreted. I3C H ,0 was used to study the crosslinking reaction with gelatin which leads to methylene and oxym ethylene bridges between gelatin-amino-groups. On ageing, hardened gelatin shows an increase in the number of m ethylene bridges.

متن کاملUltraviolet Spectrophotometric Method for Determination of Gelatin Crosslinking in the Presence of Amino Groups
The study was carried out to develop procedure for determining concentration of formaldehyde to be used for crosslinking of gelatin in the presence of drugs having amino groups. Gentamicin sulfate was used as a drug candidate due to its high content of amino acids. Gelatin crosslinking is accelerated by aldehyde-containing compounds and inhibited by amino group-containing compounds. The major m...
متن کاملDetection of formaldehyde-induced crosslinking in soft elastic gelatin capsules using near-infrared spectrophotometry.
The purpose of this research was to monitor the migration of formaldehyde from a polyethylene glycol (PEG) fill into the gelatin shell of a soft elastic gelatin capsule (SEGC) using near-infrared (NIR) spectrophotometry. SEGCs were filled with five solutions of aqueous formaldehyde in PEG (0, 0.05, 0.10, 0.20, and 0.40 v/v%), stored at ambient conditions for 48 hr, emptied, and scanned in NIR s...
متن کاملCrosslinking Of Gelatin Capsules
~emistry of the crosslinking of gelatin is a complex phenomenon. the nature of which is dependent on several factors. The present manuscript represents an attempt to answer some specific basic science issues. Two "stress" conditions are commonly known in connection with gelatin capsules. The first condition is induced by exposure to formaldehyde. The second stress condition is created by exposi...
متن کاملGenipin-Modified Gelatin: Preparation, Characterization, and Application as a Filler for Leather
Genipin, an iridoid compound extracted from gardenia fruits (Gardenia jasminoides Ellis) is a natural crosslinking agent. Because of its low cytotoxicity, genipin is increasingly used to replace both glutaraldehyde and formaldehyde as a crosslinker for proteins. Researchers have in recent years successfully demonstrated the effective use of genipin in the modification of gelatin, particularly f...
