摘要:
A process for forming a snack product and a snack formed therefrom with discontinuous characteristics (14, 16). The process includes forming a first highly cohesive dough and a second less cohesive dough matrix, combining the first and second discrete dough components into a composite dough sheet, cutting the dough sheet into a multiplicity of dough preforms, and frying the preforms to produce a snack with discontinuous characteristics (24).

A routine, direct and biochemically functional process is disclosed for detecting retrovirus in biological samples. For that purpose, structure-specific extraction with immobilised ligands directed against the viral surface is combined with function-specific enzyme reaction for retrovirus by means of reverse transcriptase, RNAse H, integrase or protease. Reverse transcription by means of reverse transcriptase, retroviral RNA and tRNA is particularly suitable for the retrovirus-specific enzyme reaction. In an ulterior detection step, the newly synthesised cDNA products are identified by radioactive, photometric, luminescent or fluorescent processes. This process represents a biochemical simulation of the natural process of retroviral infection and development within the cell (reverse transcription, integration, maturation) and allows several retroviral components, surface glycoproteins, enzymes, structural proteins, RNA and tRNA to be simultaneously detected. A process with a qualitatively improved specificity compared with state-of-the-art processes is thus obtained. The process takes 1-2 days, may be easily and routinely carried out in a microtiter format and thus allows many probes to be simultaneously processed within a short time. In addition, the process may be universally applied to all species of retrovirus by means of corresponding specific ligands. The process is suitable for detecting retrovirus for the purpose of diagnosing, following and treating viral diseases, in transfusion and transplantation medicine, in virological research and development and for the biological quality control of pharmaceutical and biotechnological products.
