Abstract Complex carrot processing technology “Mirzoi krasny” along with concentrated and powdered natural dye rich in mineral elements biologically active substances obtained powder transparent juice used the food industry. Based on obtaining absorption spectrum of dyes, it was found that main coloring pigment dye, β, are also α γ-carotenoids.A method sterilization based an IR gausted object h...

Visual and gustatory responses of Spodoptera frugiperda Hübner (Lepidoptera: Noctuidae) larvae to artificial food dyes were studied. The objective was to determine the ability of these substances to attract and elicit feeding of insect larvae to assess their feasibility for improving the efficacy of ingested insecticides. The artificial food dyes lemon green, lemon yellow, orange red, chlorophy...

Respiratory infections can be spread via 'contact' with droplets from expiratory activities such as talking, coughing and sneezing, and also from aerosol-generating clinical procedures. Droplet sizes predominately determine the times they can remain airborne, the possibility of spread of infectious diseases and thus the strategies for controlling the infections. While significant inconsistencie...

Marker dyes are often mixed with liquid insecticide formulations prior to field applications to accurately determine the characteristics and penetration of droplets into targeted habitats. We have been using FD&C Red 40 Granular DM food dye at the rate of 20 g/liter in liquid solutions of Bacillus thuringiensis israelensis (Bti) for area-wide larvicide applications against the Asian tiger mosqu...

This paper reports the application of an advanced multilayer model to study adsorption food dyes FD&C blue No. 2, acid red 18, and yellow 5 from aqueous solutions with a chitosan film. These dyes' mechanisms were discussed analyzed at 298–328 K pH 4–7 via statistical physics calculations. Physicochemical parameters utilized explain dye molecular scale. Modeling results showed aggregation phenom...

Fermentor-stabilized activated sludge from an industrial beverage bottling plant was grown on three different food sources: normal plant wastewater, plant wastewater containing high sucrose concentrations, and a synthetic glucose-based feed stock. Surface charge, hydrophobicity, and exopolysaccharide composition were measured on the stabilized bacterial flocs. Cell surface charge was measured b...

Erythrosine B is widely used for dyeing in various applications, especially in the food industry, despite its already proved toxicity and carcinogenicity. Therefore, the purpose of this study is to evaluate the efficiency of the synthesis process of US/S2O8-2 in removing erythrosine B dye from aqueous solution. In this experimental study, the removal of erythros...

The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...
