The Stability Evaluation of Strawberry Kiwi Soda at PT. Sinar Sosro

---

PT. Sinar Sosro is the first company that serves ready-to-drink tea beverages in Indonesia
and the World that was legally opened on 17 July 1974 by Soegiharto Sosrodjojo. The internship
activity was conducted in the research and development department from January until May 2023,
where activities such as physicochemical analysis, microbiological analysis, accelerated shelf life and
stability testing, and also benchmarking of products were conducted in order to gain real work
experience. Other than that, the main objective of the internship was to make a product in hopes
that it can be used as another variant of PT. Sinar Sosro product, where the stability evaluation was
done. In this project, the stability of strawberry kiwi soda was evaluated during 4 weeks of storage,
while also comparing the analysis results between the samples stored at room temperature and
chiller on each week, in terms of CO
concentration, Brix, pH, color, titratable acidity, vitamin C
content, and also the sensorial properties of the products. The experiment was conducted by
following the procedure made by PT. Sinar Sosro, except for the vitamin C content analysis, which
was done using the uv-vis spectrophotometer at 265 nm. The result shows that the strawberry kiwi
soda stored for 4 weeks at room temperature and chiller remains stable in terms of the CO
2
concentration, Brix, pH, L value, and acidity (p>0.05). However, there were several significant
differences noticed in the vitamin C content, a* and b* values, along with the sensorial properties of
the strawberry kiwi soda (p
