The present invention relates to heat stable carotene rich composition extracted through a green process. The process is solvent free and highly effective for extraction of the carotenoids and other bioactives from plant matrix. The process employs the use of chemical facilitators or cell wall degrading enzymes to increase extraction efficiency. More particularly, the invention relates to a process of preparation of carotene, phenolic and ascorbic acid enriched products from biological resources such as capsicum through a novel enzyme mediated process.
