background and objective: lactobacillus plantarum is one of the probiotics species used in functional food products. these bacteria or their purified bacteriocins are used as biological preservatives in the food industry. the first step in production of an array of probiotic products is optimizing production in fermentors. this study aimed to examine factors affecting the in vitro growth optimi...

the optimization of process conditions for the degradation of acid blue 193 by uv/peroxydisulfate was investigated using response surface methodology (rsm). the effects of four parameters namely initial k2s2o8 concentration, uv irradiation, temperature, and initial dye concentration on two process responses, color removal and the rate constants of the first-order kinetic equations, were investi...

in this study, we investigated the effects of osmotic process with or without ultrasound on solid gain (sg) and water loss (wl) of cranberries. response surface methodology was used to model and determine the optimum processing conditions for wl and sg during osmotic dehydration of samples. sucrose (40-60%) and salt (0-8%) concentrations, temperature (30-50°c) and frequency of ultrasound (0-130...

the impact resistance of new lightweight panel is studied. this panel consists of two thin metal layers bonded together by intermediate fiber/epoxy layers (mcm-sheets). to simulate a behavior of this kind of impact problem, explicit and implicit finite element software abaqus is used. in order to validate the finite element modeling, these results have been compared with experimental test resul...

response surface methodology is a common tool in optimizing processes. it mainly concerns situations when there is only one response of interest. however, many designed experiments often involve simultaneous optimization of several quality characteristics. this is called a multiresponse surface optimization problem. a common approach in dealing with these problems is to apply desirability funct...

for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

efforts to improve the quality of bakery products are increasing every day. several techniques were developed for this purpose. in this study the possibility of betterment and optimization of quality properties of dough and barbari bread with emphasis on process variables using rotatable response surface methodology were investigated. the independent process variables for baking process were do...

in a robust parameter design (rpd) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. response sur-face methodology (rsm) is one of the effective methods that can be employed for this purpose. since quality of products or processes is usually evaluated through several quality ...
