A fundamental 2-D model was developed to predict the heat and mass transfer that occur during the frying and cooling process of tortilla chips. Semi-empirical correlations were included to account for structural changes, such as shrinkage and expansion due to puffing. All water present in the tortilla chip was considered bound and led to shrinkage when removed. The parameters that were studied ...

Acrylamide levels in food, and especially in potato products, are perceived world wide as a potential public health problem. The current trials on ‘Rooster’ potato tubers purchased (as ware samples) in a supermarket and fried under domestic conditions showed that soaking (citric acid vs. water) and pre-treatments such as blanching in water and pre-frying in oil were useful for lowering the cont...

 The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp < /font>. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p < 0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunfl...

introduction: grass carp (ctenopharyngodonidella, family cyprinidae) is one of the main fresh water fish species and highly demanded aquaculture species in iran. among the cultivated fish, grass carp, also called farmed white fish, has received great attention because of its similarity to caspian white fish in iran. the muscle of fish contains important levels of nutrients which are beneficial ...

The high incidence of lung cancer among Chinese females, despite a low smoking prevalence, remains poorly explained. Cooking fume exposure during frying could be an important risk factor. We carried out a population-based case-control study in Hong Kong. Cases were Chinese female nonsmokers with newly diagnosed primary lung cancer. Controls were female nonsmokers randomly sampled from the commu...

OBJECTIVES The aim of the study was to see if a cook could be exposed to mutagenic aldehydes in fumes from frying of beefsteak using margarine, rapeseed oil, soybean oil or virgin olive oil as frying fat. In addition, levels of particle exposure were measured to make the results comparable to other studies. METHODS The levels of higher aldehydes and total particles were measured in the breath...

Baking and frying are two common food preparation methods, but there is limited knowledge about the lipid oxidation events that occur in food products prepared in these ways. Two commercially available breaded shrimp products were examined using gas chromatography, for changes in cholesterol, phytosterols, and fatty acids as a result of baking and deep frying after separation into breading and ...

In the literature, there are several empirical models to estimate the higher heating values of vegetable oils and biodiesel fuels. In this study, five of these models found in the literature were used to estimate the higher heating value of waste frying oils. When some models are used to estimate HHVs of waste frying oils, the relative errors were found up to 5% compared to the values obtained ...

A rapid method for determining the carbonyl value of frying oils has been developed using Fourier-transform infrared (FTIR) spectroscopy and chemometrics. One hundred and fifty-six frying oils with different carbonyl values were collected from an actual potato frying process. FTIR spectra in the range of 4000-650 cm(-1) were scanned with a FTIR spectroscopy apparatus using the attenuated total ...
