Abstract

The "tasty" cuisine tends to use chemical flavour agent containing monosodium glutamate (M.S.G.). M.S.G. utilizations, in long-term, may cause health problems, especially triggering cancer cells. Therefore necessary to introducing and increasing a natural flavouring agent to eliminate those health problem, such as bekai leaf. Bekai (Pycnarrhena tumefacta Miers) is familiar as a natural flavour agent (bio-vetsin) in cuisine for forest communities in Nyapa Indah Village, Berau, East Kalimantan, Indonesia.  However, until now there has been no proper analysis support for widespread utilization of bekai leaf. This paper studies the presence of phytochemicals, antioxidant and GC MS analysis from bekai leaf extracts, as well as five hedonic classifications of organoleptic test, to reinforce the need for a better understanding of consumers reaction in terms of possible acceptance of additional bekai leaves applied in soup as bio-vetsin. Present study showed that the qualitative screening of phytochemical compounds in bekai leaves ethanolic extracts revealed presence of alkaloids, flavonoids, tannins and steroids. Antioxidants of bekai leaves using 2,2-diphenyl-1-picrylhydrazy (DPPH) method showed that concentrated extract has 80.1%, which predicted can improve immune for inhibitory action of cancer cells. GC MS analysis suspected that bekai leaf extract contained 5 (five) major compounds, i.e. oxirane dodecyl, gamma sitosterol, vitamin E (α tokoferol), 9.12-Octadecadienoic acid (Z,Z)- (natural linoleic acid), and 3-Tetradecanynoic acid (myristic acid). These chemical compound in related with their phytochemical were predicted to contained strong antioxidant activities and some of them commonly used as flavour agent in cuisine for some food industries. Meanwhile, results of organoleptic tests presence in three soup variant have been provided that soup with additional Bekai leaves has best acceptance in the children's perception due to it has an unique smell, tasty and no colour changing compared with M.S.G. added and control. Thus bekai leaf can be used as an innovation for healthy food and new market opportunities for M.S.G. substitutes.
