Abstract

Functional properties of natural food sources create alternative to develop new food product. The consumption of foods and beverages containing probiotic microorganisms is a growing, global consumer trend. The comparative evaluation of orange juice inoculated with Lactobacillus species with known probiotic properties was performed. The prebiotics used in orange juice is raw asparagus root powder. After that measure the growth of bacteria after one day. To measure the growth of probiotic bacteria in orange juice at first measure the absorbance of the orange juice. Next Pour plate was done to observe the growth of probiotic bacteria. To observe the sustainability of probiotics in orange juice these test were done after two or three day's interval. When bacterial colony grows on petri dish biochemical test was conducted and got positive result. Which mean that asparagus influence the growth of probiotic bacteria. This study suggests that asparagus extract exert a positive effect on growth of lactic acid bacteria in orange juice.
