introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

In this work, the optical fiber chemical sensor had been introduced based on Fabry- Perot interferometer technique. Single-mode fibers were used with different diameters (125, 60, 50) μm. Chemical etching technology is to reduce diameters. Sensor heads immersed in chlorophyll dye concentrations. The submitted shows good sensitivity and linearity towards variation concentration. Both peak wavele...

Rhodamine B is a synthetic dye that usually used in the textile and paper industries. According to Permenkes No.239/Menkes/Per/V/85 regarding certain dyes, it states rhodamine dangerous substance. prohibited for use as food additive because has chelating compounds chlorine which can cause cancer humans. Based on above problems, review of articles was carried out by collecting journal literature...

In this issue, a retired allergist and immunologist in a Letter to the Editor describes his and his wife’s experience in identifying annatto as a probable cause of his wife’s severe irritable bowel syndrome (IBS). They had first contacted our Digestive Disease Section for information. I knew nothing about annatto, but proceeded to find out some basic information. Much to my surprise, no one in ...

Amaranth dye is an organic compound largely used in the food and beverage industries with potential toxicity effects on humans. In this paper, a new electrochemical sensor for determination of amaranth foods was reported, where kind V2O5 nanoplate (V2O5-NPs) employed as electrode modifying materials. The modified enhanced its signal obviously exhibited wider linear response ranging from 0.1-270...

The consumption of artificial food dye (AFD) during childhood and adolescence has been linked to behavioural changes, such as hyperactivity. It is possible that the vulnerability to AFDs is modified by prenatal stress. Common consequences of prenatal stress include hyperactivity, thus potentially leading to synergistic actions with AFDs. Here, we investigated the compounding effect of multigene...

Allergies and food sensitivities can both be considered as "adverse reactions individualistic" to food. Are pathological and individual forms because they affect a few individuals in way rather serious; immediate or delayed reactions occur instead with simple effects histamine, or, in severe cases with respiratory and anaphylactic shock The eggplant (Solanum melongena L.) is known to cause food...

Baits offer several advantages over other insecticide formulations in the control of populations of the German cockroach, Blattella germanica (L.). However, they may fail to target certain life stages that feed only sparingly. Recently we have demonstrated that 1st instars are signiÞcantly more vulnerable to insecticidal baits when adults are present. By preventing adults or nymphs from eating ...

An enzyme-based electrochemical biosensor was investigated for the analysis of Sunset Yellow synthetic food dye. A glassy carbon electrode was coated with a poly(acrylamide-co-ethyl methacrylate) membrane to immobilize laccase using a single-step photopolymerization procedure. Poly(acrylamide-co-ethyl methacrylate) membrane was demonstrated to have acceptable water absorption and suitable for b...

Reducing amyloid-β (Aβ) accumulation is a promising strategy for developing Alzheimer's Disease (AD) therapeutics. We recently reported that a triphenylmethane food dye analog, Brilliant Blue G (BBG), is a dose-dependent modulator of in vitro amyloid-β aggregation and cytotoxicity in cell-based assays. Following up on this recent work, we sought to further evaluate this novel modulator in a the...
