Angkak, a fermentation product of rice by Monascus sp., is used for natural food coloring, spices, and medicine by Indonesian people who believe in its pharmacological properties. However, Monascus sp. also produces a secondary metabolite, hepato-nephrotoxic mycotoxin citrinin. The biosynthesis of pigments and citrinin is generated from a tetraketide point in the polyketides pathway. This study...

Abiotic stress can alter key physiological constituents and functions in green plants. Improving the capacity to monitor this response in a non-destructive manner is of considerable interest, as it would offer a direct means of initiating timely corrective action. Given the vital role that plant pigments play in the photosynthetic process and general plant physiological condition, their accurat...

in this study, we have investigated the effects of mix of tomato (solanum lycopersicum) & carrot) daucus carota ( and red bell pepper )capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (astronotus ocellatus sp., agassiz, 1831), which are generally white with red patches in the dorsal skin. the fish were fed diets con...

Changes in the biosynthesis of individual carotenoid pigments have been investigated during fruit ripening of five cultivars of red pepper (Capsicum annuum L.): Mana, Numex, Belrubi, Delfin, and Negral (a chlorophyll-retaining mutant when ripe). The study was carried out throughout the ripening process, and with special emphasis on the ripe stage, to discover possible differences between cultiv...

This study aims to investigate the physicochemical characteristics, phenolics content, and oil composition of pomegranate oil seeds (PSO). Quality indices, pigments, phenolics content, and antioxidant activity were determined. PSO was fractioned into polar lipids: glycolipids (GL) and phospholipids (PL). Sterols profile and fatty acids composition of total lipids (TL), GL, and PL were determine...

Processing steps including bleaching, deodorizing, and milling are imperative for improving the functionality of distillers grains in various food matrices, as well as improving consumer acceptance. Utilization of distillers grains in food products is of particular interest. Various parameters were explored for the removal of pigments, including raw DDGS (diameter 0.384) or milled DDGS (0.329 m...

1. Many birds sequester carotenoid pigments in colourful patches of feathers to advertise or compete for mates. Because carotenoids can be scarce in nature and serve valuable physiological functions, only the highest-quality individuals are thought to acquire or allocate more pigments for use in sexual displays. 2. A critical but rarely tested assumption of carotenoid-based signals is that the ...

The present study investigates the effects of Glomus mosseae and Glomus intraradices on the resistance of green basil plants to salinity stress. The findings suggested that there was an interaction of effects between mycorrhiza fungi inoculation and salt stress on the physiological characteristics of Ocimum basilicum L. On one hand, salinity decreased percentage of root colonization, root lengt...
