Anthocyanins, synthesized via the flavonoid pathway, are a class of crucial phenolic compounds which are fundamentally responsible for the red color of grapes and wines. As the most important natural colorants in grapes and their products, anthocyanins are also widely studied for their numerous beneficial effects on human health. In recent years, the biosynthetic pathway of anthocyanins in grap...

In recent years, with the increase in income our country, it is seen that most of consumers have awareness healthy eating and their interesting organic food. The emergence various diseases such as cancer obesity plays a major role this preferred. addition, prolongation life expectancy, desire to quality great importance. Due harm caused by foods obtained conventional methods human health enviro...

Chestnut shell melanin can be used as a colorant and antioxidant, and fractionated into three fractions (Fr. 1, Fr. 2, and Fr. 3) with different physicochemical properties. Antioxidant activities of the fractions were comparatively evaluated for the first time. The fractions exhibited different antioxidative potential in different evaluation systems. Fr. 1, which is only soluble in alkaline wat...

Common synthetic dyes, e.g., Weak Acid Pink Red B (APRB, C.I. 18073), Mordant Blue 9 (MB, C.I.14855) and Acid Brilliant Blue 6B (ABB6B, C.I. 42660), can be removed from water by in situ hybridization with CaCO(3), BaSO(4) and Ca(3)(PO(4))(2) and the resulting hybrids thus prepared used as plastic colorants. All the hybrids can be processed into polypropylene (PP) at 200 °C with good color inten...

The aim of this study was to investigate the feasibility of two decontaminating processes, ozonation and electrocoagulation, to decolorize wastewater generated by humid finishing leather production. With the objective to determine if one or both process could remove color, benchscale experiments were conducted with three different colorants, representative of the main dye groups: di-azo (CI Dir...

The performance of drug treatment and assessments different drugs' side effects both can be affected by the interaction between food additives drugs. Organic compounds such as colorants dyes are utilized in a wide range foods. In this study, adsorption behavior colorant dye sunset yellow (SY) loratadine was examined. procedure is conducted at dosages, various SY concentrations, temperature (288...

A gamut's size and shape may depend on many factors other than the physical properties of its primary colorants. The color gamut created by certain types of frequency modulated (FM) screening technologies appears to be larger than those created by conventional halftone (AM) screens while using the same colorants. Most device gamuts are determined by the physical properties of the substrate and ...

Pigments extracted from natural products are widely used for food coloration in Japan. An investigation concerning the photo-mutagenicity and photo-carcinogenicity of frequently used colorants in Japan was performed. Colorants examined were from Laccifer lacca (lac-color), Coccus cacti (cochineal-color), Carthamus tinctorius (carthamus yellow), Gardenia augusta (gardenia yellow and gardenia blu...

A synthetic protocol for the preparation of an indium oxide nanoparticle-functionalized poly(methacrylic acid-glycidyl methacrylate-ethylene dimethacrylate-ethanediamine) monolithic column is reported. Various techniques, including scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermal gravimetric an...
