Abstract

From the selected area of Dharan, Sunsari, Nepal, conventional and organic tomatoes were grown and tested with different parameters. Conventional tomatoes contained less value of Mg, Ca, K, Cu and Mn, but more value of Fe than organic tomatoes, where as Pb and Ni were not detected.The Zn was found to be same in both tomatoes sample. The sizes of conventional tomatoes were reportedly bigger than organic tomatoes. The viscosity and surface tension of organic tomatoes juice were reported to be higher than in conventional tomatoes juice. The refractive index value was found to be lower in conventional tomatoes juice than in organic tomatoes juice. The vitamin C value was found to be higher in conventional tomatoes juice than in organic tomatoes juice. The comparative study of color, juice containing capacity, storage capacity and firmness of organic and conventional tomatoes of Dharan,Sunsari,Nepal has also been included.Int. J. Appl. Sci. Biotechnol. Vol 5(1): 91-97

Highlights

Nowadays organic farming is very famous than conventional farming in our Country
The determination of metals in tomato was measured by Atomic absorption spectroscopy (AAS)
The residue was removed and filtrate was used for measuring the surface tension and viscosity of both tomatoes juice

Summary

Introduction

Nowadays organic farming is very famous than conventional farming in our Country. Atmospheric conditions, soil environment and farming process influences the tomato farming. The tomato is used widely (Lugasi et al, 2003). Many foods are possible such as sauces, catsup (ketchup), puree, pastes, soups, juices and juice blends etc (Preedy and Watson, 2008).Tomato is an important source of micronutrients, certain minerals and carboxylic acids (Caputo et al, 2004; Hernandez-Suarez et al, 2007).
