White Wines by Color imetr ic Assays
For evaluation of flavonoid phenols in the low concentration range in white table wines, four colorimetric assays have been compared: (a) reaction with Folin-Ciocalteu reagent before and after precipitation of flavonoids in HCI-methanal (FC); (b) reaction with vanillin (VAN); (c) reaction with 4-(dimethylamino)-cinnamaldehyde (DAC); and (d) a rapid browning test at 60°C in oxidative medium (POM...
متن کاملVoice quality as a pitch-range indicator
Pitch perception plays a central role in processing speech prosody. Since f0 varies from speaker to speaker and from context to context, effective pitch-range normalization is thus important to uncover intended linguistic pitch targets. It has also been speculated that voice quality may play a role in pitch-range perception. Our previous study demonstrated that spectral balance indeed effective...
متن کاملFour-color laser white illuminant demonstrating high color-rendering quality.
Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors. Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors. Therefore it is a common belief that white light produc...
متن کاملSpectroscopic Analysis of Polyphenols in White Wines
Spectroscopic analysis was used to study the effect of wine processing on phenolic composition. Various classes of phenolic compomtds were detected and characterized by ultraviolet (UV) and Infrared (IR) spectroscopy in white grapes of Sauvignon Blanc and French Colombard, as well as in wines prepared from these grapes. Comb/ned treatment with bentonite, egg albumin and Polycinr AT decreased th...
متن کاملAbrupt Intralesional Color Change on Dermoscopy as a New Indicator of Early Superficial Spreading Melanoma in a Japanese Woman
Diagnosis of superficial spreading melanoma in the early stage is often difficult, even with dermoscopy. We report the case of a 37-year-old Japanese woman with superficial spreading melanoma in her left buttock. The lesion developed 20 years before becoming visible and gradually enlarged over the past few years without any symptoms. Physical examination showed a well-demarcated dark-brown macu...
