Most food and beverages contain artificial flavor compounds. Creation of artificial flavors is not an easy step
and it is hardly ever completely effective. In this paper, we introduce an in silico method in optimization of microbial
strains of flavor compound synthesis. Previously, several algorithms exist such as Genetic Algorithm, Evolutionary
Algorithm, Opt Knock tool and other related techniques which are widely used to predict the yield of target compound by
suggesting the gene knockouts. The use of these algorithms or tools to is able to predict the yield of production instead of
using trial and error method for gene deletions. Nowadays, without using in silico method, the direct experiment methods
are not cost effective and time consuming. As we know, the cost of chemical is expensive and not all flavorists are able to
afford the cost. However, the main limitations of previous algorithms are that they failed to optimize the prediction of the
yield and suggesting unrealistic flux distribution. Therefore, this paper proposed a hybrid of continuous Bees algorithm
and Flux Balance Analysis. The target compound in this research is vanillin and glutamate compound. The aim of study is
to identify optimum gene knockouts. The results in this paper are the prediction of the yield and the growth rate values of
the model. The predictive results showed that the improvement in terms of yield may help in food flavorings.
Keywords: Continuous bees algorithm, flux balance analysis, glutamate, optimization, vanillin, yeast.
