Characterization and Conversion of Microbial Pigments into Water Soluble Pigments for Application in Food Products

Abstract Microbial colours with different shades like pink (Rhodotorula), red (Chromobacterium), yellow (Sarcina) and light yellow (Micrococcus) using apple pomace (a waste from apple juice) were produced by solid state fermentation, characterized and modified into water soluble pigments. Biocolour from Rhodotorula had maximum absorption in ethanol, hexane and acetone at 200–550 nm with λ-max between 480 and 490 nm. In case of Chromobacterium sp., ethanol, petroleum ether and hexane gave the highest absorption between 520 and 540 nm (narrow range). Pigment of Micrococcus sp., had maximum absorption between 200 and 400 nm with λ-max in narrow range (400–600 nm) scanning between 480 and 490 nm in ethanol. Dark yellow colour pigment of Sarcina gave the maximum absorption between 200 and 500 nm in ethanol. All the biocolours examined were carotenoids, insoluble in water and thus, have limited applications in food. Aminoacid, benzoic acid and gelatin were employed to make these pigments water soluble by reflexing at different pH values viz., 3, 7 and 9.2 for each pigment. Maximum conversion (51 %) of pigment of Rhodotorula occurred using gelatin at pH 9.2. In case of Chromobacterium using amino acetic acid at pH 9.2 it was 60 %. It was 55 and 56 % at pH 7 and 3, respectively. In Sarcina, at pH 9.2 maximum conversion (48 %) took place using amino acetic acid, whereas in pigment of Micrococcus sp. 40 % conversion took place using amino acetic acid at pH 9.2 and the minimum conversion occurred using amino benzoic acid at pH 3. It is concluded that the pigments produced by Rhodotorula, Micrococcus and Chromobacterium can be modified chemically to make them water soluble thus, making possible their use in various food products.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
