Abstract

This investigation highlights the chemical seed husk extracts of Terminalia bellirica and Terminalia arjuna. On the other side, the consumer highly favored orange juice, but its shelf life is less than 7 days at 4°C. So, juice requires a preservation press to increase self-life. This chemical preservation may be harmful to health in the long run. This study showed the effect of aqueous and ethanol extracts seed husks (at 0.5 and 1% concentrations) on orange juice. Compared to sodium benzoate (Artificial chemical preservation) it stored all treatments at 4°C for 14 days. This study showed a higher quality of natural preservation during the juice storage period compared to artificial. Seed husk extracts are a natural product that showed control of pathogenic growth as artificial preservation. Orange juice still seems to be fresh for more than a week without detectable, unfavorite physical or chemical changes compared to the control at 4°C.
