| Background: Effect of different storage and distribution conditions on the quality of diet drinks was studied. Ongoing demand for low calorie soft drinks requires special attention to this matter. Materials and Methods: To realize this research, 42 numbers of soft drinks produced using Aspartame as sweetener were prepared and stored at different storage conditions for 6 months. The samples were stored at cold temperature (4˚C), room (20˚C) and incubator (45˚C). Chemical Compositions including Aspartame, DKP and Formaldehyde were measured every month. Results: Obtained results showed the after-production amount of Aspartame in diet soft drinks decreased from 513±6.2 to 412±7.4, 296±8.4, and 0 after 6 months stored in frig (4˚C), room (20˚C) and incubator (45˚C), respectively. The amount of DKP formed in diet soft drinks after 6 months stored in frig (4˚C), room (20˚C) and incubator (45˚C) was 20.2±3.2, 102±5.8, 167 ±4, respectively. The amount of formaldehyde formed in diet soft drinks increased from 0 to 0.75±0.04, 0.83±0.03 and 0.92±0.06 in above mentioned storage conditions, respectively. Conclusion: Diet soft drinks stored at cold room maintained their quality up to 4 months without any significant changes. However, those stored at higher temperature and/or longer times had lost their quality versus temperature and time. |
