Humans can be exposed to primary aromatic amines (PAAs) by the usage of a variety of synthetic products which come in contact with food and plastic children toys. PAAs are mainly originated from synthetic azo dyes widely applied as colorants on plastics and also from the use of adhesives based on polyurethanes (PU) in laminated food packing materials.

Carmoisine (E122) is a synthetic azo dye that is generally used to give a red color to food products. In this work, a sensitive and simple method was developed for the determination of carmoisine based on cloud point extraction. To obtain the optimum conditions for the extraction efficiency of carmoisine, the effects of different analytical parameters such as H2 SO4 concentration, concentration of Triton X-114, and equilibrium temperature were studied. The calibration graph was linear between 0.05 and 5.

Optimization techniques predict the conditions required to increase the efficacy of azo dyes degradation by microbial sources and also decrease the number of experimental runs to achieve the maximum percentage of degradation. Interaction of variables such as medium components and process parameters can be determined using optimization tools.

Pigments are the chemical substances that absorb the light of visible region. Pigments are compounds that are widely used in industries. Non-toxic nature of pigment produced by a number of microorganisms make them ecofriendly for utilization in dye, foodstuff, pharmaceutical, cosmetics and other industrial purpose. Industrial production of natural food colorants by microbial fermentation has several advantages such as cheaper production, easier extraction, higher yields through strain improvements, no lack of raw materials and season independent.

Value addition in floriculture increases the economic value and consumer appeal of any floral commodity. The profitability of a commodity is increased when the raw material is converted into a value added product which can directly or indirectly influence floral market to a great extent. An experiment was conducted to standardize the tinting technologies in China aster var. Local white. In this study, the food dyes viz., Apple Green, Lemon Yellow and Orange Red were used in three different concentrations including control.

Salmonellosis is one of the most common causal food borne disease in India. An in-house loop-mediated isothermal amplification (LAMP) reaction was established and evaluated for sensitivity and specificity in detecting the presence of Salmonella spp. isolates in foods of animal origin from Mumbai, India. The aim of this study was to develop in-house LAMP for simple and inexpensive detection of Salmonella spp. in animal origin foods using specifically designed primers targeting invA gene contains sequences unique to this genus. The reaction was optimized using genomic DNA of S.

This study deals with Clitoria ternatea L. which is commonly known as 'butterfly pea' and „shankhapushpi‟, „Unchan‟ in Thailand, „Neel Aporajita‟ in Bangladesh is a climbing vine bearing purple or white flowers. It is a medicinal plant belonging to the family Fabaceae. In tropical Asia including India, the purple flowers are used for many medical purposes. The flower extract consists of antioxidant activity and protective effect. It has been commonly used as anti-stress, anti-depressant, anti-microbial, and in anti-inflammatory treatments.

Water is a essential source, nowadays days the resources of the water and its availability is lacking. Industrial pollutions like textiles, leather, food industries, pharmaceuticals are the major part of pollutants and creating a major problems. Especially textile areas, uses high colorant synthetic chemical dyes, and also recalcitrant, mutagenic in nature.

Nowadays, synthetic dyes are widely used in textile, leather, cosmetics, paper, food and pharmaceutical industries instead of natural dyes due to its availability, stability, low cost and color intensity which emerges a new problem of residual color in the discharged effluent. Improper discharge of dye effluent in aqueous ecosystems is aesthetically unpleasant and impedes photosynthetic activity reducing sunlight penetration, dissolved oxygen concentration and water quality in total.

Bixa orellana commonly known as annatto is one of the oldest known natural dye yielding plants native to Central and South America. Various parts of annatto have been widely used in the traditional medical system for prevention and treatment of a wide number of health disorders. The plethora of traditional uses has encouraged researchers to identify and isolate phytochemicals from all parts of this plant.
