Abstract

This Dissertation / Report is the outcome of investigation carried out by the creator(s) / author(s) at the department/division of Central Food Technological Research Institute (CFTRI), Mysore mentioned below in this page.

Item Type:	Student Project Report
Additional Information:	Coffee beans are a rich source of various bioactive compounds. Among these, caffeine, chlorogenic acids, trigonelline and diterpenes are important as they contribute a lot to the quality of coffee brew. Various factors viz., agronomic, climatic and soil factors are responsible for variation in levels of these important metabolites in beans. All these compounds are important from health point of view. Understanding metabolite pathway during coffee fruit development would be having implications to track the metabolite profile at different developmental stages, and also to identify the key genes involved in respective metabolite biosynthetic pathway through differential expression studies. Profiles of caffeine, trigonelline, cafestol and kahweol in beans during ontogeny of Coffea canephora (robusta) fruits was studied. There was an inverse relationship found between trigonelline and caffeine during ontogeny of fruits. In case of coffee diterpenes which are considered as antinutritional factors, found in high levels in initial stages of fruit development, with a relative decrease of cafestol and kahweol up to green matured stages, followed by further reduction by harvesting stage of fruits.
