What Are Fluorescent Pigments and Dyes?

  Pigments and dyes are chemical substances used to color another material (often referred to as   colorants ).   Fluorescent Pigment Manufacturer   and dyes are special colorants that absorb light energy at one wavelength, such as invisible ultraviolet light (UV), and then emit light at a longer wavelength, producing a specific color. Another way of describing the fluorescence process is that higher energy light (shorter wavelength = higher energy)  excites  fluorescent material to emit lower energy visible light (longer wavelength = lower energy). Fluorescent materials can emit different colors throughout the visible color spectrum depending upon their physical and chemical properties. The Two Main Types of Fluorescent Colorants Visible Fluorescent Pigments and Dyes Visible fluorescent pigments and dyes are visible colorants that become brighter when excited by light. These colors are usually referred to as  daylight-fluorescent  colors and enha...

Types And Applications Of Synthetic Food Colours

  Adding colours to food plays with both episodic as well as semantic memory. Food colourants are additive dyes that impart various appealing hues to the food substance.  Food Colour Manufacturers in India  can be natural or synthetic. Natural food colours are the ones that are produced naturally by extracting colours from organic veggies. The other class of colours falls as inorganic or synthetic colours which are produced chemically. The precursor compounds are modified through a wide range of chemical processes. The way in which our brain reflexes, we expect to acquire the taste of food as it appears. Neurologically we perceive that any black appearing food is either burnt or maybe bitter in taste, if any food has a tint of orange in it that means it is tangy, red food automatically appears to be spicy and there are many more perceptions of food we conjure. Synthetic colours are classified into Azo dyes, triarylmethane dyes and chemically related colours. All the colou...
