Abstract

This research aimed to study the shelf life of ready-to-drink dragon blood tea during storage at room temperature (30±2°C) and refrigerator temperature (4±2°C) over a period of 24 days. The experimental results showed that dragon blood tea stored at room temperature could only be preserved for one day, on the day of production. In contrast, when stored in a refrigerator, it could be preserved for 15 days. The dragon blood tea stored at room temperature exhibited significant color changes, with the hue angle shifting from red purple to yellow red. There was an increase in light transmittance (Transmittance, %T670), decrease in alkalinity, and a significant increase of citric acid content (p≤0.05). Storing at refrigerator temperature could help decrease the color changes, with the hue angle of the dragon blood tea remaining red purple throughout the storage time. There were slight changes in acidity and citric acid content. Regarding microbial quality, it was found that dragon blood tea stored at room temperature had significantly higher total microbial, yeast, and mold count when compared with that stored in the refrigerator, resulting in shorter shelf life. In terms of sensory quality assessment, consumers consistently rated the taste of dragon blood tea stored in the refrigerator as moderately likable throughout the 15 days of storage time.
