Abstract :
Microbial safety of commercially available RTS is achieved by adding higher levels of preservatives than recommended. Chemical preservatives at higher intake results in health problems. Hence this study was carried out to find out to produce RTS without adding chemical preservatives. For level of acidity was selected and to protect their sensory properties the same Brit/Acid ratio was maintained. Both pineapple and mix fruit juices prepared using higher levels of acids were sensory evaluated for their suitability of consumption. Brit/Acid ratio 14.8/0.32 was a final to be significantly acceptable for both juices. Microbial studies showed all the treatments were free of microbial growth even without added chemical preservatives. No microbial growth was observed in commercial Brit/Acid ratio. Hence higher acid level added treatments can commercially be recommended to produce RTS without significant changing of sensory properties. Hence preservatives added for the preservations of RTS can be eliminated by increasing acid level through maintaining Brit/Acid ratio.
