Determination of Selected Metals in Fruit Wines by Spectroscopic Techniques
Background The determination of metals in different types of food and beverages samples has drawn significant attention due to several reasons with the most important one being the nutritional and toxic effects of these elements or their compounds. The knowledge of certain elements content in wines/fruit wines is of special interest due to their toxicity in case of excessive intake and also the...
متن کاملDetermination of Trace Metals and Essential Minerals in Selected Fruit Juices in Minna, Nigeria
Levels of trace metals and essential minerals in selected fruit juice samples purchased from Minna were determined using atomic absorption spectrophotometer (AAS) and Flame photometer. From the obtained result, Cu, Fe, Mn, Na, and Zn were present in all the samples, while Cd, Pb, and Cr were not detectable in all the samples. Concentrations of K range between 1.31 ± 0.10 and 41.20 ± 0.10 mg/100...
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 کاملComparative Analysis of Total Phenolic Content in Sea Buckthorn Wine and Other Selected Fruit Wines
This is the first report from India on a beverage resulting from alcoholic fermentation of the juice of sea buckthorn (Hippophae rhamnoides L) using lab isolated yeast strain. The health promoting potential of the product was evaluated based on its total phenolic content. The most important finding was that under the present fermentation condition, the total phenolic content of the wine product...
متن کاملStudies of tropical fruit ripening using three different spectroscopic techniques.
We present a noninvasive method to study fruit ripening. The method is based on the combination of reflectance and fluorescence spectroscopies, as well as gas in scattering media absorption spectroscopy (GASMAS). Chlorophyll and oxygen are two of the most important constituents in the fruit ripening process. Reflectance and fluorescence spectroscopies were used to quantify the changes of chloro...
