“…With the increasing demand for eco-friendly/non-toxic colorants [1][2][3], there has been an increasing trend towards replacing synthetic colorants by natural alternatives because the latter cause fewer adverse health effects and have interesting biological properties, such as antioxidant and anticancer activity. Natural colorants can be obtained from plants, insects, microorganisms, animals, and minerals [4,5]. A wide range of colorants has been produced through fermentative processes by filamentous fungi, including carotenoids, melanin, flavins, phenazine, quinones, and violacein [6].…”

A B S T R A C TOver the last few years, synthetic colorants have been increasingly replaced by natural alternatives that cause fewer adverse health effects and can show biological activity. These biocompounds can be produced by fermentative processes using microorganisms such as bacteria and filamentous fungi. However, the biocompounds must be extracted from the fermented broth before industrial application. Thus, the development of effective techniques for the extraction and purification of biocolorants with high recovery is of great interest. The main goal of this study was to evaluate the recovery of natural colorants produced by Talaromyces amestolkiae using aqueous micellar two-phase system (AMTPS) composed of Triton X-114 and Ionic Liquids (ILs) from the imidazolium family as co-surfactants. Preliminary experiments were performed to determine the binodal curves in both presence and absence of fermented broth containing the red colorants. Subsequently, a set of partitioning experiments was performed using the developed systems. Under all conditions, the red colorants were partitioned mainly into the micelle-rich phase. The systems with low concentrations of Triton X-114 and ILs showed high partition coefficients. The system (0.1 wt% [C 10 mim]Cl + 3 wt% Triton X-114) with the highest partition coefficient (K RC = 6.12) was used to study the effect of temperature on partitioning. The partitioning of the red colorants was strongly influenced by the temperature, and K RC increased to 24.71 at 45°C. The results of this study demonstrate that the partitioning of biomolecules can be controlled by the presence of ILs, mainly by electrostatic interactions, or by the proper adjustment of the partitioning temperature.

“…Similarly silk fabric dyed with eucalyptus leaf extract dye solution exhibited maximum colour strength at 90 °C of dyeing temperature (Mongkholrattanasit et al, 2011). Bouzidi et al, 2016 also found that increase in dye bath temperature resulted in rise in colour strength reaching highest at 100°C. It was may be attributed to the aptitude of dye migration and aggregation into the fiber which reveals higher K/S at this temperature.…”

The nature is abode to numerous plants, animal and mineral resources that offersustainable alternative to chemicalsused in textile dyeing. In this paper an effort has been made to utilize the roots of Himalayan nettle plant for fabric dyeing which grows abundantly in-the higher altitude of Uttarakhand as a weed plant. The extraction and dyeing variables were optimized for application on silk fabric on the basis of colour strength and wash fastness rating. Dye extraction carried out in aqueous medium at simmering temperature for 1.5 hoursresulted in better colour depth and washing fastness. Similarly, dyeing of silk at 90ºC for 90 minutes using 3 gm per 100 ml powdered dye material yielded better dyed samples in terms of colour strength and wash fastness. The obtained dye recipe is easy to be used by dyeing units at minimal cost since no chemicals are added during dyeing and raw material can be collected from pastures, around croplands and nearby forest areas.

“…It is in this context that we have tried to evaluate the colorimetric characteristics of Opuntia species pigments by measuring CIELAB ( L *, a *, b *) parameters.As shown in Table 4, CIELAB parameters highlighted significant differences between the studied Opuntia species. In fact, the value of L * in O. ficus indica was the most important by comparison to the other species indicating significant transparency of this extract 48 . The appearance of a food product is judged by the transparency of its colour, which is often a sign of quality.…”

Introduction: Synthetic colourants are subject to various allergies. As a result, the use of plant-based additives has proved promising. Objective: It is in this perspective that our objective was undertaken to investigate natural colourants from edible cactus. Opuntia species populations were singlesequence repeat (SSR) fingerprinted, the analysis of betalains and phenolic compounds and the evaluation of their biological potentials were also characterised. Results: Photometric quantification of betalains and phenols showed an interspecific variation across Opuntia species. Opuntia ficus indica fruits showed the highest betalain [betaxanthins; 843.67 and betacyanins; 1400 mg/100 g dry weight (DW)] and polyphenol contents. Reversed-phase high-performance liquid chromatography (RP-HPLC) analysis showed that the variation of individual phenols profile was influenced by interspecific and genetic factors. Isorhamnetin-O-(di-deoxyhexosylhexoside) was the major compound and its content varied according to Opuntia species, while catechol was the predominant phenolic compound in O. humifusa with 1.88 μg/g DW. Concerning cactus species, Opuntia colourants exhibited a potent antiradical activity [half maximal inhibitory concentration (IC 50) up to 1 μg/mL]. Opuntia species were effective against Gram-positive and Gram-negative bacterial strains [inhibition zone (IZ) up to 27 mm]. A high genetic diversity within Opuntia genotypes based on SSR markers was revealed. UPGMA (unweighted pair group method with arithmetic mean) dendrogram and PCoA (principal coordinate analysis) based on natural pigments and antimicrobial profiles indicated significant variation. The correlation approach proved the presence of a probably metabolic relationship between genetic markers, pigments and their biological activities. Conclusion: A possible association between molecular approach and metabolic profile analysis of Opuntia allows tracing the relationship among species for its genetic conservation.
