A novel edible colorant lake prepared with CaCO3 and Monascus pigments: Lake characterization and mechanism study

Food Chemistry, 2023
Monascus pigments (MPs) were adsorbed using calcium carbonate to produce CaCO3-MPs lakes. The fundamental properties and formation mechanism of the lakes were investigated. Results indicated that CaCO3 displayed a high enough affinity for the MPs to form colorant lakes, while the MPs tended to transform the CaCO3 crystals from calcite to vaterite.

Color Polymorphism and Predation in a Lake Victoria Cichlid Fish

Copeia, 2008
Haplochromine cichlid fish have radiated into hundreds of species in East-African lakes, possibly driven by divergent sexual selection on body coloration. We studied the color polymorphic Lake Victoria cichlid Neochromis omnicaeruleus, in which a presumably ancestral phenotype with blue males and brown females co-occurs with two distinct classes of ...

Some Notes on Water Color in Keweenaw Bay (Lake Superior)

Journal of Great Lakes Research, 2004
Spectral subsurface irradiance reflectance—intrinsic water color—was derived from above-water radiance measurements using a hand-held spectroradiometer along a transect on Keweenaw Bay, Lake Superior. The reflectance spectra were typical of oligotrophic lacustrine waters. The reflectance peak wavelength shifted from 484 nm at stations farthest offshore

Effect of Dispersion on the Coloring Properties of Aluminum Dye Lakes

Journal of Pharmaceutical Sciences, 1988
The effect of particle size on the coloring properties of aluminum dye lakes was studied. Lakes impart color by dispersion in the medium to be colored. Dispersion techniques were developed, using scanning electron micrographs for particle sizing. The color strength and the trichromatic colorimetric properties were calculated from reflectance values ...

Color pattern variation in Lake Erie water snakes: inheritance

Canadian Journal of Zoology, 1993
The hypothesis that color pattern variation in Lake Erie island water snake (Nerodia sipedon) populations results from the opposing effects of natural selection and gene flow requires that this variation have a genetic basis. To determine whether color pattern variation is genetically based, data on the color pattern of wild-caught females and their ...

Aluminium based dye lakes from plant extracts for textile coloration

Dyes and Pigments, 2012
Abstract Production of concentrated natural dyes is a pre-requisite for a re-introduction of plant colorant based dyes into modern textile dyeing operations. Aluminium salts such as Al 2 (SO 4 ) 3 .14-15H 2 O or KAl(SO 4 ) 2 .12H 2 O can be used to precipitate extracted plant dyes from aqueous extracts at pH 5.0–5.5.
