Grain protein films plasticized with glycerol were prepared from corn zein (CZ), wheat gluten (WG), and a 2.3:1 mixture of wheat gluten and soy protein isolate (WG/SPI). Moisture adsorption curves of the three types of protein films at 25° C and within an approximate water activity range of 0.11 to 0.84 were obtained using a static gravimetric method. The Smith, Oswin, Halsey, and Guggenheim-An...

We pose a monotonicity conjecture on the number of pseudo-triangulations of any planar point set, and check it on two prominent families of point sets, namely the so-called double circle and double chain. The latter has asymptotically 12nnΘ(1) pointed pseudo-triangulations, which lies significantly above the maximum number of triangulations in a planar point set known so far. ⋆ Parts of this wo...

Is every zonohedron 3-colorable when viewed as a planar map? This question arose out of work described in [RSW01]. An equivalent question, under a different guise, is posed in [FHNS00]: Is the arrangement graph of great circles on the sphere 3colorable? Assume no three circles meet at a point, so that this graph is 4-regular. Circle graphs in the plane can require four colors [Koe90], so the ke...

Understanding sorption isotherms is crucial in food science for optimizing the drying processes, enhancing shelf-life of food, and maintaining quality during storage. This study investigated sweet cherry powder (SCP) using static gravimetric method. The experimental water curves lyophilized were determined at 30°C, 40°C, 50°C. then fitted to six isotherm models: Modified GAB, Halsey, Smith, Osw...

Amorphophallus konjac fresh tubers are often used as a raw material for making food because it has fairly high nutritional content. Therefore, is very important to measure the equilibrium moisture content of andprocessed tuber. The present study aimed determine best model represent adsorption and desorption isotherms tuber slices. samples weresliced into slices (3.0 × 3.0 0.8 cm) rinsed in 0.2%...
