Studying various aspects of the manuscripts may be important in explaining the actual values of work, and the ways of protecting these values. Therefore, in this research 10 paint samples (blue and red) from the five manuscripts related to Safavid period (16th century) were analyzed to explore their nature and structure. First, the related literature regarding the frequent types of the paints i...
Synthetic pigments have been employed universally for decades, resulting in environmental pollution and human health risks. So, it was critical to find out novel natural pigments, such as microbial that were safe alternative synthetic pigments. Bacterial getting the importance attention of both researchers industries mass production various colored not only used industrial applications but also...
The growing interest in natural alternatives to synthetic petroleum-based dyes for food applications necessitates looking at nontraditional sources of natural colors. Certain sorghum varieties accumulate large amounts of poorly characterized pigments in their nongrain tissue. We used High Performance Liquid Chromatography-Tandem Mass Spectroscopy to characterize sorghum leaf sheath pigments and...
Mold growth is a continuing issue when it comes to human health, as well growing concern in localized wood decay, numerous ‘traditional’ molds have been found soft rotting capabilities. inhibitors on the market are often synthetic; however, fungal kingdom has wide range of more ‘natural’ options. Pigments produced by many fungi be toxic other fungi, especially fungi. This study looked at pigmen...
Tracking of pigment accumulation and secretion in extractive fermentation of Monascus anka GIM 3.592
BACKGROUND Monascus pigments are promising sources for food and medicine due to their natural food-coloring functions and pharmaceutical values. The innovative technology of extractive fermentation is used to promote pigment productivity, but reports of pigment trans-membrane secretion mechanism are rare. In this study, tracking of pigment accumulation and secretion in extractive fermentation o...
Background: using root beet powder pigments without extract or using organic solvents, to study the stability of pigments in model foods tomato paste, strawberry jam, juice, and burger, and to perform preliminary studies consumer acceptance of model foods containing them. Objective: The overall aim of this study was to use microencapsulation technique to increase the stability of red beet pigme...
Abstract Inorganic pigments have been very important substances for human life thousands of years. They contributed and continue to contribute the beautification our daily habitat accentuation differentiation objects, influence thoughts, moods, feelings. The industrial manufacture inorganic based on growing chemical physical knowledge started around 1800. Before that, natural materials or manuf...
ALLEN, D. M., W. N. MCFARLAND, F. W. MUNZ, and H. A. Pos-roN. 1973. Changes in the visual pigments of trout. Can. J. Zool. 51: 901-914. The proportions of two visual pigments (rhodopsin and porphyropsin) were examined in four species of trout under experimental and natural conditions. Brook trout (Salvelinus fontinalis), rainbow trout (Santo gairdneri), and brown trout (Salmo truita) have diffe...
In diatoms, the main photosynthetic pigments are chlorophylls a and c, fucoxanthin, diadinoxanthin and diatoxanthin. The marine pennate diatom Haslea ostrearia has long been known for producing, in addition to these generic pigments, a water-soluble blue pigment, marennine. This pigment, responsible for the greening of oysters in western France, presents different biological activities: allelop...
