We present a general complete gliadin extraction procedure based on reducing and disaggregating agents for both heated and unheated foods as a crucial tool for gliadin analysis. The new extraction solution is used for corresponding proteins from rye (secalins) and barley (hordeins). The cocktail was employed as the extraction method in the international ring trial evaluation of sandwich R5-ELISA as proposed by the Codex Alimentarius and organized by the Working Group on Prolamin Analysis and Toxicity.

The influence of gel texture on parameters such as positioning of food material in the oral cavity during mastication, and salivation, and their influence on aroma release in vivo was studied. Retronasal perception was followed by means of time-resolved sensory evaluation, while volatile release patterns were observed by means of PTR-MS. A clear correlation was found between individual-specific consumption patterns and the respective sensory perception. Also, gel texture could be clearly correlated with respective physicochemical release patterns in vivo and to the corresponding retronasal aroma perception.
