This study was undertaken to determine if the oral consumption of red beetroot food color would result in an inhibition of N-nitrosomethylbenzylamine (NMBA)-induced tumors in the rat esophagus. Rats were treated with NMBA and given either regular water ad libitum or water containing 78 microg/mL commercial red beetroot dye, E162. The number of NMBA-induced esophageal papillomas was reduced by 4...

Federal Food, Drug, and Cosmetic Act (FD&C) food dyes make industrial goods like foods beverages more appealing. These are synthetic typically used instead of natural due to their color, stability, low cost. Research has implied that children sensitive the amount dye in products. The products is proprietary information, so it can be challenging determine how much ingesting. In this study, u...

36 LLE Review, Volume 77 Photodynamic therapy is a treatment in which the combination of a dye, light, and oxygen causes photochemically induced cell death. Observations of this effect occurred at least as early as the end of the last century. In 1900, Raab reported that the dye acridine rapidly killed paramecia when exposed to light, but had no effect in the dark.1 This observation quickly ins...

Fluorescent in situ hybridization (FISH) using 16S and 23S rRNA-targeted probes together with construction of an archaeal 16S ribosomal DNA (rDNA) clone library was used to characterize the microbial populations of an anaerobic baffled reactor successfully treating industrial dye waste. Wastewater produced during the manufacture of food dyes containing several different azo and other dye compou...

Reproduction of most insects depend on nutrients accumulated during the larval stage, but many lepidopteran species will also depend on nutrients obtained at the adult stage. Feeding at the adult stage allows the intake of carbohydrate and amino acid rich solutions, which may have an effect on the species reproduction and population growth. The objectives of the current study were to characteri...

In many industrial areas such as in food, pharmaceutical, cosmetic, printing, and textile, the use of synthetic dyes has been integral with products such as azo dye, anthrax, and dyestuffs. As such, these industries produce a lot of waste by-products that could contaminate the environment. Bioremediation, therefore, has become an important emerging technology due to its cost-sustainable, effect...

BACKGROUND Yellow dye tartrazine is a potential cause of exacerbations of asthma, allergic rhinitis and urticaria in atopic patients. The Brazilian Sanitary Surveillance Agency (ANVISA) published a consultation about the possibility of issuing a label warning addressing these potential effects of food and drugs containing tartrazine. The present study aims to evaluate tartrazine dye safety in a...

There are more than 100,000 different synthetic dyes available on the market, produced in over 700,000 tons annually worldwide. They are used in the textile, paper, cosmetics, food and pharmaceutical industries. Some of them are dangerous to living organisms due to their possible toxicity and carcinogenicity. About 10% of the above mentioned amount is lost in wastewater, which justifies the con...

Annatto is commonly used as a coloring agent in the food industry and has antimicrobial and antioxidant properties. In this study, genetic algorithm-artificial neural network (GA-ANN) and adaptive neuro-fuzzy inference system (ANFIS) models were used to predict the effect of annatto dye on Salmonella enteritidis in mayonnaise. The GA-ANN and ANFIS were fed with 3 inputs of annatto dye concentra...

Contaminated water is the primary source of any disease. Water may be contaminated by number of pollutants and dyes are one of them. Malachite green (MG) dye is widely used as biocide in the aquaculture industry to controls fungal attacks, protozoan infections and also used in food and textile industries for various purposes. Surface and ground water is contaminated with dyes due to discharge o...
