Developing a spectroscopy-based high throughput assay for anthocyanin content in corn
Anthocyanins are one of the only natural colorants approved by the US Food & Drug Administration (FDA) and hence, are highly sought after as natural color pigment for the food industry. However, anthocyanins are susceptible to gradual degradation when exposed to certain food processing techniques …

Effects of temperature, light and nutrition on color and anthocyanin content of poinsettia bracts
… determining the concentration of bract anthocyanins, and to determine the effect of temperature, light intensity and nutrition on the color and the anthocyanin content of poinsettia bracts. A procedure was developed to objectively measure the color poinsettia bracts using the Hunter …

Comparison of fermentation characteristics between colored corn and yellow dent corn using two dry grind process methods
… is needed. One way is to use corn rich in anthocyanin content as feedstock. Anthocyanin imparts red, blue and purple color to corn kernels. Anthocyanin could also affect yeast during fermentation. The objective of this study was to evaluate the performance of anthocyanin rich corn in dry …

Characterization of antioxidant activities from fruits rich in delphinidin or malvidin anthocyanins
Anthocyanins have been shown to possess specific antioxidant capacities, which may provide an underlying protective effect against many chronic diseases . Although the antioxidant capacity of anthocyanins has been well established, less is known about the extent to which specific anthocyanin …

Phytochemical diversity and genetics of purple corn
… colorants, especially from sources rich in anthocyanins, red to purple plant pigments. Anthocyanin-rich purple corn is being explored as a potential economical source of natural colorant. Our recent survey of colored corn maize germplasm identified a purple corn landrace, Apache Red (AR), …

Characterization of anthocyanin production in maize germplasm
Anthocyanins are the visually appealing red-orange to blue natural pigments present in most plant species. Because of their ease of aqueous extraction and rich color, anthocyanins make suitable natural replacements for synthetic dyes like FD&C Red 40. Increasing consumer demand for natural …

Effect of light stress on the homoiochlorophyllous resurrection plant Craterostigma wilmsii
… examined. Differences in chlorophyll ( a + b) content, carotenoid (x + c) content, anthocyanin content, ascorbate peroxidase activity, and ultrastructure, were assessed. Shaded inner whorl leaves do not experience lightchlorophyll interactions, carotenoids and anthocyanin pigments do not …

Characterization of chalcone synthase genes in red raspberry cultivar (rubus idaeus)
The biosynthesis of anthocyanin compounds involves type III polyketide synthases (PKSs): chalcone synthase (CHS), which is the first enzyme of the flavonoid synthetic pathways leading to synthesis of various anthocyanins. The European red raspberries are a commercially important fruit that needed …

Encapsulation, Color Stability, and Distribution of Anthocyanins from Purple Corn (Zea mays L.), Blueberry (Vaccinium sp.), and Red Radish (Raphanus sativus) in a Cold-Setting Pectin-Alginate Gel.
Anthocyanins are a broad class of water soluble pigments found in a wide array of plants. They are responsible for a variety of the attractive colors found in fruits including red, purple, orange, and blue. There use as a natural alternative to synthetic colorants has been investigated extensively …

Evaluation and modification of processing techniques for recovery of anthocyanins from colored corn
… natural alternatives of synthetic dyes. Anthocyanins can be used as a replacement of synthetic FD&C Red 40 dye. However, their recovery from conventional sources is uneconomical due to higher inputs and lower economic value of the processing residues. The potential of using colored corn …
