Natural pigments are high value molecules for food industry as well pharmacy, perceived the best choice today’s consumers given their origin and safety. However, its use is limited by lability which hinders application in products. In this work there was evaluated stability of phycocyanin C gelatin candies when added with trehalose citric acid; formulated were digested synthetic gastric juice p...

Food acceptability and appeal are significantly influenced by colour. Harmful effects associated with synthetic colorants well established, research is currently focused on developing natural, chemical-free substitutes from fungal sources, broad applications in food, medicine, textiles agriculture. Additionally, the market’s dearth of natural red colour requires creation novel pigment alternati...

Diastereomeric 2-methoxycyclopentyl analogues of a natural quorum sensing signaling molecule from Pseudomonas aeruginosa were synthesized and screened in pigment production assays with P. aeruginosa and Serratia strain ATCC39006.

By-products derived from food processing are attractive source for their valuable bioactive components and color pigments. These by-products are useful for development as functional foods, nutraceuticals, food ingredients, additives, and also as cosmetic products. Lycopene is a bioactive red colored pigment naturally occurring in plants. Industrial by-products obtained from the plants are the g...

The presence of pigment has been demonstrated in different nervous structures such as those of retina, substantia nigra, and locus coeruleus. These pigments have also been described in the pineal gland of different mammal species. Histochemical and ultrastructural studies of the pineal gland of female viscacha (Lagostomus maximus maximus) were performed to analyze the presence of pigmented cell...

Choroideremia is an incurable X-linked retinal degeneration caused by mutations in the gene encoding Rab escort protein-1. A group of clinically defined and genotyped patients were studied to determine: (1) the degree of rod and cone dysfunction and structural abnormality in the central retina and the level of macular pigment; and (2) the response of macular pigment and foveal vision to a 6 mon...

In the Lower Grand Coulee, Washington, Diaptomus nevadensis in Soap Lake contains larger amounts of the carotenoid astaxanthin than in Lake Lenore. During winter, Diaptomus sicilis contains larger amounts of pigment in both lakes, but in summer individuals from Lake Lenore are much reduced in pigment while those from Soap Lake are unchanged. The amount of astaxanthin might be a reflection of th...

The use of ascomycetous fungi as pigment producers opens the way to an alternative to synthetic dyes, especially in the red-dye industries, which have very few natural pigment alternatives. The present paper aimed to bio-prospect and screen out 15 selected ascomycetous fungal strains, originating from terrestrial and marine habitats belonging to seven different genera (Penicillium, Talaromyces,...

In several retinal degenerative diseases, including age-related macular degeneration, the retinal pigment epithelium, a highly functionalized cell monolayer, becomes dysfunctional. These retinal diseases are marked by early retinal pigment epithelium dysfunction reducing its ability to maintain a healthy retina, hence making the retinal pigment epithelium an attractive target for treatment. Cel...
