OBJECTIVES To review current knowledge on the definition of tooth whiteness and its application within dentistry, together with the measured range of tooth colours. METHODS 'Medline' and 'ISI Web of Sciences' databases were searched electronically with key words tooth, teeth, colour, colour, white and whiteness. CONCLUSIONS The application of colour science within dentistry has permitted th...

The colour changes that occur in kiwifruit during the dry process were experimentally studied in order to determine the magnitudes of the parameters for a corresponding colour change model. The drying experiments were carried out under five air temperatures of 40, 50, 60, 70 and 80°C, air velocity of 1.0 m/s and kiwifruit slice thickness of 4 mm. The colour parameters for the colour change of t...

Abstract The aim of the study was to analyze influence rapeseed protein isolate on physico-chemical properties, sensory attributes and storage gluten-free bread prepared basis corn potato starch mixture with addition pectin guar gum. Starches used in formulation were replaced amounts 6–15%. characterized terms physical including volume, crumb structure color, which accompanied assessment. Textu...

This study examined the effect of adding antioxidants, namely curry leaf extract (CLE) and butylated hydroxyanisole (BHA), on physicochemical properties ghee during deep frying. The results showed that addition CLE to resulted in significant changes L*, a*, b* values, likely due extraction chlorophyll molecules preparation. Deep frying caused a decrease L* values an increase a* ghee, as well re...

In order to evaluate the effect of raw meat's freezing/thawing process on meat products produced from them, frankfurter's quality was monitored. Fresh beef grounded and separated into two lots - first lot immediately used in preparation frankfurters (G1F), other frozen stored at -18?C for 4 weeks, when it second group (G2F). Physicochemical technological properties were investigated fresh (CG-F...

Beras kencur drink is an Indonesia’s traditional beverage containing several antioxidant compounds that are good for human health. Thermosonication technology was chosen to process the beras drink. This research aimed evaluate activity and color of thermosonication with compared control untreated pasteurization treatment. The treatment used a probe at frequency 22 kHz, while conventional condit...

BACKGROUND The tremendous supply and low cost of distillers dried grains with solubles (DDGS) make it an attractive feedstuff for aquaculture diets. Also, several studies have shown that DDGS can be successfully fed to various finfish. The objective of this study was to evaluate the effects of inclusion rate of DDGS (0, 250, 500 g kg(-1) ), feed moisture content (350, 450 g kg(-1) ) and die ope...
