چکیده

Confocal Scanning Laser Microscopy (CSLM) has advantages over conven tional light microscopy and electron microscopy. In particular the possibility to perform optical section ing, allowing the disturbance free observation of the three-dimensional internal structure, offers new possibilities in microstructural studies of food sys tems. The technique is further considered to be very valuable in the study of dy namic processes and tran sport phenome na. Preliminary results are discussed of an inve s tigation into the microstructure of fat spreads, mayonnaise, cheese and rising dough us ing this CSLM technique . Initial paper received October 8, 1987 Manuscript received October 30, 1987 Direct inquiries to I. Heertje Telephone number: 31 10 460 5513

Application of Electron Spin Resonance Techniques to Model Starch Systems

Starch model systems were examined by electron spin resonance (ESR) techniques with either 16-DOXYL-stearic acid or TEMPO spin probes in water or hexane. Room temperature starchwater-16-DOXYL-stearic acid spectra showed strong adsorption occurred between the starch and probe. Starch-water-TEMPO spectra at room temperature did not show strong adsorption between starch and probe, but did show som...

Fundamental Study on the Impact of Gluten-Free Starches on the Quality of Gluten-Free Model Breads

Starch is widely used as an ingredient and significantly contributes to texture, appearance, and overall acceptability of cereal based foods, playing an important role due to its ability to form a matrix, entrapping air bubbles. A detailed characterisation of five gluten-free starches (corn, wheat, rice, tapioca, potato) was performed in this study. In addition, the influence of these starches,...

Interactions of Hydrocolloid and Emulsifier on Rebuilding Gluten Network of Damaged Wheat and Taftoon Bread Quality

Many factors can affect wheat gluten properties and functionality. One of the most important, of these factors, is wheat bug damages. Insect injects a salivary proteinase into wheat kernel that results a significant weakening effect on the gluten, in substantial losses in physical quality, dough properties and baking performance. Bread baked with the insect – damaged flour had poor quality and ...
