Abstract:
In today’s world there is a growing demand for healthy food products has lead to the development of “Nutraceutical Food Products”. Development of natural food colours or bio-colours is a growing research area to shift the synthetic food colours. Bio-colours have many health benefits properties such as anti oxidant activity, food products stabilization, anti cancer property, etc. The main challenge faced by the industry is the production of natural food pigments in bulk to replace the synthetic colours and also this extraction process from plant origin is time consuming, expensive and the product yield is low. The sources are non-renewable. In this regard, the micro organisms are less expensive and renewable alternative source. In this review paper the competitive study of different microbial pigment is done as well as use of microbial pigment as an alternative of synthetic food pigment and the nutraceuticals properties of those pigments are discussed. This paper also highlights the challenges faced and advanced technologies used in this developing the pigment extracted from microbial sources.
