Tomatoes are cultivated, harvested and commercialized on a wide scale all over the world. This poses the question ·'Would the tomatoes last long?" Fresh tomatoes place on a counter would only last for a week and extended for another week if stored in refrigerator at 23°C. The onset of senescence is triggered by ripening process. Ripening process in tum triggered by multitude of factors. The major factor known is the initiation of ethylene biosynthesis. The accumulation of ethylene would trigger multiple enzymatic processes along with multiple protein synthesis. The transition of chloroplasts into chromoplasts is driven by enzymatic action that results in the loss of green coloration among tomatoes. Carotenoids on the other hand are the main coloration pigments that give the orange and red coloration to tomatoes. Single-frequency sound wave at 1 kHz as the treatment agent of the project proved to have delays ripening process when applied to a group of tomatoes. The results showed a noticeable different between controlled group and treated group. The color transitions from green to red of the tomatoes were considerably slower in treated group during the whole period of 15 days. The sound wave treatment also reduces the respiration rate of tomatoes as the headspace gas sample analyzed revealed that the amount of C02 was lower in the gas sample of treated group. The GC test showed those treated groups only have 0.39886% C02 content out of 50 mL gas sample taken. In contrast, controlled group's C02 content was 1.27148% with the same volume of gas sample. The result obtained proved that single-frequency sound wave at I KHz was capable of delaying ripening process as well as reducing respiration rate in tomatoes Faculty Of Applied Sciences 2017 Student Project NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/22982/1/PPb_MUHAMMAD%20AFIQ%20AZMAN%20AS%20C%2017_5.PDF Azman, Muhammad Afiq (2017) Single-frequency sound wave delays tomato (solanum iycopersicum) ripening by suppressing respiration and regulates lycopene / Muhammad Afiq Azman.
