Using encapsulated Nannochloropsis oculata in white chocolate as coloring agent

Journal of Applied Phycology, 2020
Colored chocolate products have gained importance in recent years. This increases the importance of identifying potential natural colorants for chocolate technology. In this study, Nannochloropsis oculata microalgae which were grown by using tubular photobioreactor in two different forms (spray-dried and encapsulated by using a spray dryer and ...

A Review on Food Coloring Agents-Safe or Unsafe?

Research Journal of Pharmacy and Technology, 2019
Food coloring agents are added to foods to make customer perception. They act as emulsifying agents, stabilizers, sweeteners, antioxidants, preservatives and so on. They also increase attractiveness to different types of products. Coloring of the food product not only gives pleasant, attractive color but also flavor, natural value of the product.

Recovery and Reuse of Color Developing Agents

SMPTE Journal, 1980
Recovery and reuse of color developer overflows is commonly done by one of three methods: (1) reconstitution, (2) ion exchange, and (3) electrodialysis. An alternative to reusing all or part of the overflow by application of one of these methods is to recover and reuse only the color developing agent.

[4] Colored sulfonyl chloride as an activating agent for hydroxylic matrices

1987
Publisher Summary The major difficulty with many methods of activating hydroxylic matrices for immobilizing enzymes or bioligands is that the resulting immobilized material leaks from the matrix. Dansyl chloride was found as an effective, but weak, activating agent whose displacement could be followed by fluorescent measurements or, qualitatively, by

Persistent urticaria caused by a common coloring agent

Postgraduate Medicine, 1989
As this case illustrates, foods or drugs may be ignored as possible causes of urticaria when they are not commonly accepted offenders or when they previously have been consumed with no adverse effect. In some instances, an additive or dye in a food or drug may be responsible for the reaction. In addition, a change of brands or dosage form of a drug may

Chelating Agents as Color Stabilizers for Epinephrine Hydrochloride Solutions

Journal of the American Pharmaceutical Association (Scientific ed.), 1956
Some amino acid derivatives have been examined for their effect on inhibition of discoloration of epinephrine hydrochloride solutions buffered at pH 4.0. The chelating agents were studied alone and in combination with sodium bisulfite. The efficacy of these agents was evaluated by comparing their ability to retard the discoloration of epinephrine ...

Effects of Eye Structure and Color on Attributions for Intelligent Agents

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2006
Participants rated machine “faces” which varied in terms of facial feature shape, whether the eyes had a pupil or not, and seven eye colors (blue, green, orange, pink, red, purple, or yellow). Ratings were made for aggression, friendliness, intelligence, trustworthiness, and degree of animation.

A Multi-Agent System for Color Video Decomposition

2021
Dynamic texture (DT) analysis is an important research area in the field of computer vision. Actually, several methods are used to recognize the dynamic texture, but a good compromise between computational cost and performance is hard to achieve. For color sequences, we propose a fast color decomposition model which splits a video into two components ...

Red mud as a substitute coloring agent for the hematite pigment

Ceramics International, 2018
Abstract Red mud (RM), a highly alkaline iron oxide rich sludge obtained during the production of alumina, was treated to work as a coloring agent for ceramic glazes. The approach aims the valorization of this residue, adding environmental and economic value.
