Effect of Spices on Purple Tea Acceptability and Antioxidant Properties

This study explored what happens when common spices are added to purple tea made from the TRFK 306 variety of Camellia sinensis. 

Researchers looked at three main things: taste, antioxidant activity, and overall consumer appeal.

Purple tea is naturally rich in anthocyanins and catechins, which give it strong antioxidant potential. 

The question was simple: Can spices make purple tea more enjoyable to drink without reducing its benefits too much?

Why this study matters

Tea is not just about health. It is about taste and experience. 

Purple tea can have a mild or unfamiliar flavor for some people. The researchers wanted to see if spices could improve how people perceive it while keeping its antioxidant properties.

They tested common spices used in drinks and food.

These included ginger, lemongrass, nutmeg, cinnamon, rosemary, and a mixed spice blend often called tea masala. 

Each spice was added in different amounts. The teas were then evaluated by a sensory panel.

What the research found

First, pure purple tea had the highest antioxidant activity. On its own, it scored higher than any of the spices tested individually.

Second, when spices were added in larger amounts, the overall antioxidant activity of the blend tended to decrease compared with plain purple tea. This does not mean spices are unhealthy. It simply means that the more you dilute the tea, the more you reduce its original antioxidant strength.

Third, some spices improved taste significantly. Cinnamon at around 10 percent of the blend was rated especially well. Lemongrass and nutmeg also made the tea more enjoyable when used in moderate amounts.

Fourth, balance was important. When too much spice was added, people liked the tea less. Most panelists preferred blends where the tea’s natural flavor was still noticeable.

Fifth, cost increased as more spices were added. This matters for producers trying to keep the product affordable.

What this means in everyday terms

Purple tea already has strong antioxidant potential. Adding small amounts of certain spices can make it more pleasant to drink without completely losing those benefits.

Cinnamon, lemongrass, and nutmeg were especially helpful in improving taste. 

But when spices dominate the blend, the tea’s natural antioxidant profile becomes weaker and the overall character changes.

Practical guidance

If you want both flavor and antioxidants, use light spice blends rather than heavy ones.

Start with small amounts of spices like cinnamon or lemongrass, especially if someone is new to purple tea.

Remember that changing the blend affects not just taste, but also antioxidant levels and cost.

The takeaway

This research shows that spices can improve the drinkability of purple tea when used in moderation. 

With the right balance, purple tea can remain both enjoyable and rich in antioxidants, without overpowering its natural qualities.
