“…Extracted from the seed and pulp of fruits of the tropical Bixa orellana Linn. tree, annatto natural colourant has been employed for colouration of food products as well as textile materials (Scotter et al, 1998;Selvi et al, 2013;Santos et al, 2014;Cosentino et al, 2016). The principal colouring components of this carotenoid yellow-orange-red dye are bixin and norbixin as shown in Scheme 1.…”

Purpose The purpose of this study is to investigate the possibility of dyeing polyester (PET) fabric with natural dye extracted from annatto seeds using high temperature dyeing method. Design/methodology/approach PET fabric was dyed with annatto extract by varying dyeing parameters (temperature, time, pH and dye concentration) to determine the optimum dyeing conditions. The influences of KAl(SO4)2, FeSO4, gallnut mordants or a commercial UV absorber on colour yield and fastness properties were further studied. Findings Optimum results were obtained when the fabric was dyed at 130°C for 30 min in a dyebath containing 15 per cent (owf) annatto dye at pH 6. The dyed fabric had an orange shade and exhibited good to excellent wash, crock, perspiration fastness and fair light fastness. Further dyeing with mordants or UV absorber mostly resulted in lower colour yield and similar fastness properties. Research limitations/implications Although the light fastness was slightly improved to moderate level for the sample with UV absorber, a noticeable colour staining on cotton portion of multi-fibre fabric occurred when subjected to standard washing test. Compared to C.I. Disperse Orange 73, the annatto dye exhibited comparable colour fastness but had inferior light fastness when dyed at approximately the same colour strength. Originality/value Natural colourants from annatto seeds can be used to dye PET fabric at high temperature without mordants, yielding deep orange shade and satisfactory fastness properties. This study provides a promising application to reduce the environmental impact of synthetic dyes.

“…In addition to the performance reported in the removal of emerging contaminants, irradiation-based AORPs have proven highly effective in the removal of natural dyes from food industry wastewater. Observed efficiencies were up to 48% for pure tincture and up to 100% for dilute solutions at a 32 kGy irradiation dose [78]. In municipal wastewater effluent disinfection, 95% removal of coliforms at a 0.2 kGy dose and 99% removal at a 0.5 kGy dose were measured [79].…”

Emerging contaminants’ presence in water, wastewater, and aquatic environments has been widely reported. Their environmental and health-related effects, and the increasing tendency towards wastewater reuse require technology that could remove to a greater degree, or even mineralize, all these contaminants. Currently, the most commonly used process technologies for their removal are advanced oxidation processes (AOPs); however, recent advances have highlighted other advanced treatment processes (ATPs) as possible alternatives, such as advanced reduction processes (ARPs) and advanced oxidation-reduction processes (AORPs). Although they are not yet widely diffused, they may remove contaminants that are not readily treatable by AOPs, or offer better performance than the former. This paper presents an overview of some of the most common or promising ATPs for the removal of contaminants from water and wastewater, and their application, with discussion of their limitations and merits. Issues about technologies’ costs and future perspectives in the water sector are discussed.

“…En el clúster rojo, sobresalieron otros importantes temas de investigación, por ejemplo, el uso como aditivo alimentario (Miller et al, 2017), el cual incluye pureza y calidad, estabilidad, degradación y decoloración. Además, se agruparon estudios enfocados en determinar sus propiedades terapéuticas para la prevención de cáncer (Goudarzi et al, 2019a;2019b), caracterización como aditivo alimentario en combinación con antocianinas y carotenoides (Fernández-López et al, 2013;Cosentino et al, 2016), así como las técnicas principales utilizadas para su estudio como la foto espectrometría, HPLC (Bonan et al, 2013). Evolución temática de la investigación, según las palabras del título de los documentos El análisis con bibliometrix de las palabras contenidas en los títulos de los documentos sobre D. coccus, y ácido carmínico y sus derivados, divididos en cuatro periodos de publicación (1980-1998, 1999-2007, 2008-2015 y 2016-2019), permitió determinar una tendencia más clara de la evolución de la temática abordada a lo largo de los años.…”

El objetivo del estudio fue identificar las temáticas emergentes de la producción científica publicada en revistas de corriente principal, su visibilidad y sinergias a través de un enfoque de indicadores bibliométricos (IB) unidimensionales y multidimensionales sobre Dactylopius coccus, ácido carmínico (AC) y derivados, de 1980 a 2019. Los IB se obtuvieron con los programas informáticos Excel®, bibliometrix, y VOSviewer. Durante el periodo en estudio se registró un crecimiento de las publicaciones en el cual predominaron los artículos científicos en inglés, concentrados en dos revistas: Food Chemistry y Journal of Raman Spectroscopy. I. Karapanagiotis resultó el autor con la productividad más alta; los autores con mayor influencia en la generación de nuevo conocimiento fueron M. Leona (576 citas) y F. Casadio (568 citas) ambos de los Estados Unidos de América (EE. UU.). La investigación principal se orientó a la identificación, caracterización y análisis del AC con diferentes técnicas. Otras temáticas emergentes e innovadoras destacadas fueron la aplicación del AC en celdas solares, y sus propiedades terapéuticas como antioxidante y para prevención de cáncer. Algunos de los temas recurrentes se relacionaron con aspectos biológicos del insecto, los efectos secundarios asociados con el consumo o exposición al AC, a la tinción de fibras naturales o animales y a sus aplicaciones como aditivo alimentario.
