Abstract
Abstract Consumer awareness of the adverse biological effects of synthetic dyes makes the demand for commercial foods and drinks with natural ingredients increase. The use of natural dyes is increasing and is in demand by consumers in the industrial world. Natural dyes have been used in several sectors such as food, clothing, arts, coatings, and energy. The low stability and brightness of the natural red color are affected by exposure to light, temperature, pH and etc. The co-pigmentation process makes the stability and brightness of natural dyes. The copigmentation method is known that there are two type, liquid and powder. In addition, the combination of copigmentation additives and the correct configuration of the spray dryer process can increase quality color fastness and stability.
Highlights
Color is very important because it is one of the characteristics of the first time by consumers
The manufacture of coloring powders uses a drying method derived from liquid / extracted wood extracts which is sprayed together with gas so that it becomes like steam or can be called fogging [33]
The stability and brightness of natural dyes can be improved by using the copigmentation method
Summary
Color is very important because it is one of the characteristics of the first time by consumers. Consumer demand for commercial food and drinks with the use of natural ingredients has increased This makes the need for dyes in the industry is very large. Some natural dyes have lacks in terms of color stability and brightness that are affected by light exposure, temperature, pH, etc. We need an alternative to increasing the brightness and color stability of natural dyes products. The quality of natural dyes derived from Caesalpinia Sappan L. extract has been investigated for its stability and has succeeded in increasing colorfastness by adding chitosan [6]. The use of the red cactus pear powder encapsulation method is carried out at high temperatures [4]. The addition of co-pigment material that has a high refractive index value can affect the brightness of natural dyes. This will provide an overview of the development of natural dyes that consumers are interested in
