composite gel; pasting properties; microstructure; gelatinization; texture

Résumé :

Textural, thermal and microstructural properties of single component gels and binary composite gels (BCG) of high amylose corn starch (Hylon VII) mixed with wheat flour at different wheat flour/Hylon VII (WF/H) ratios (95:5, 90:10 and 85:15) and temperatures (100, 121 and 135ºC) were investigated. The visual appearance showed that as Hylon VII was increased in BCG, the stronger gel was achieve ...

Termes Agrovoc :

polyphenols; antioxidant activity; response surface methodology; ultrasound-assisted extraction

Résumé :

The central composite rotatable design by response surface methodology was applied for optimization of ultrasonic extraction conditions of Bene hull (Pistacia atlantica subsp. Mutica) polyphenols. The sonication time, temperature and ethanol-water ratio were independent parameters studied for the extraction optimization. Total polyphenols and antioxidant potentials of extracts in terms of ferr ...

Termes Agrovoc :

yield; texture characteristics; cheese; ultrasound bath and probe; quality characteristics

Résumé :

In this study, the effects of bath and probe ultrasound treatments were investigated on yield, texture (hardness, adhesion, cohesion, springiness and chewiness), pH and moisture content of fresh white cheese. The times 2, 4, 6 minutes and 5, 10, 15 minutes were used in probe treatment (frequency 20 kHz) and bath treatment (frequency 37 kHz), respectively, at temperatures of 40, 50 and 60°C in ...

Termes Agrovoc :

moisture content; artificial neural networks; back propagation; convective drying; garlic

Résumé :

In this study, artificial neural networks (ANNs) was utilized for modeling and the prediction of moisture content (MC) of garlic during drying. The application of a multi-layer perceptron (MLP) neural network entitled feed forward back propagation (FFBP) was used. The important parameters such as air drying temperature (50, 60 and 70°C), slice thickness (2, 3 and 4 mm) and time (min) were cons ...

Termes Agrovoc :

sensory analyzer; image processing; anfis model; gluten free bread

Résumé :

In the study, the effect of compositional parameters (Xanthan, Corn flour and quinoa flour content) on sensory characteristics and image features of gluten free bread were evaluated. Results showed, addition of quinoa and corn flour significantly decreased L* value and increased a* value of crust and crumb of gluten free bread. Also, increased percentage of corn flour has led to decreased amou ...
