A three-layer artificial neural network (ANN) model was developed to predict the remained DO (deoxygenation) in water after DO removal with an enzymatic granular biocatalyst (GB), based on the experimental data obtained in a laboratory stirring batch study. The effects of operational parameters such as initial pH, initial glucose concentration and temperature on DO removal were investigated. On...

ABSTRACT: Kefir is fermented milk that has a unique flavor because of acetaldehyde, diacetyl, acetoin and ethanol. The aim of this study was to evaluate flavor and aroma compounds present in kefir. Two types of starter (Christian Hansen and Sacco) and three levels of temperatures (30, 33 and 35oC) were used for the preparation of kefir samples. The samples were analyzed for acetaldehyde, diacet...

The purpose of this study was to determine the quality dadih with bamboo in Taiwan, namely Thorny (Bambusa stenostachya Hackel) different incubation times. materials used are tubes, banana leaves and Alpine goat's milk from National Pingtung University Science Technology (NPUST) Taiwan. Dadih is made by pasteurizing at a temperature 65oC for 30 minutes, allowed stand until 30oC, poured into tub...

The hybrid nanofluid's synergetic effect is proportional to the mixing ratio. However, One Factor at A Time (OFAT) method only displays optimised ratio when used in respective experiments specified. Thus, purpose of this study optimise nanoparticle using Design Experiment (DOE) Expert 11 cover entire range ratios with fewest possible. prepared nanofluid comprises Titanium Dioxide (TiO2) and Gra...
