INFLUENCE OF ORGANIC FARMING ON VOLATILE COMPOUNDS IN METHANOLIC FRUIT EXTRACTS OF CHILI (CAPSICUMANNUUM L.)

Abstract

In India nearly,3.56 million hectaresof area is being managed organically (certified) with limited internal inputs to keep fruits and vegetables chemical-free. Thepresent study aims to obtain bioactive volatile compounds profile of chili fruits grown under organic and conventional farming system in the same climatic conditions. Fields practicing organic farming ORG I (since last 2-3 year), ORG II (5-6 years) and ORG III (8-9 years) were selected. fruit extracts obtained from three experimental fields and one conventional field were analyzed through Gas Chromatography and Mass Spectroscopy. The current experimental study on comparative analysis of nutrient content and effect of pesticides on chili fruits has been conducted in the year 2018. Study based on soil quality, temperature condition, amount of organic matter, pesticide spray, and year of practicing as an organic field.GC-MS analysis of conventional chili recorded a high number of compounds contrasting to organically grown chili which recorded a lesser number of compounds.GC-MS analysis of chili fruit samples grown in different agricultural conditions showed various volatile compounds. Comaprative data shows higher compounds in conventionally grown samples while lower quantity in organically grown samples. Nutritional compounds like ascorbic acid (Vitamin C) were recorded 13.22% in organic fruits in comparison to conventional chili fruits (4.37%).Capsaicinoidsand fatty acid contents were reported manyfold in organically grown chili in comparison to conventional chili fruits. Reports are in favor to promote more and more organic farming systems for nutritional enhancement in food crops.
