Bubble tea, or boba tea, started as a drink from Taiwan. It has grown into a global industry worth over USD 2.46 billion in 2023. Experts expect it to reach USD 4.08 billion by 2030 (Source: Fortune Business Insights, 2024).
One of the most iconic components of this beverage is the chewy balls that sit at the bottom of the cup. But what exactly are these "boba pearls"? Let’s dive deeper into their composition, production, and types.




What Are Boba Pearls Made Of?

People call the black pearls in bubble tea tapioca pearls. Manufacturers mainly make them from tapioca starch. This starch originates from the cassava root, which people also know as Manihot esculenta. This starch is gluten-free, flavor-neutral, and highly elastic when cooked making it perfect for chewy textures.

Ingredients of Classic Tapioca Pearls:

  • Tapioca starch (~85–90% of dry mass)

  • Water (~8–10%)

  • Brown sugar or caramel syrup (for color and mild sweetness)

  • Food-safe stabilizers (optional, for industrial-grade products)


How Tapioca Pearls Are Manufactured 

  1. Gelatinization: Tapioca starch is mixed with hot water to form a viscous dough.

  2. Shaping: The dough is rolled into 8–10 mm balls using rotary drum granulators or extrusion machines.

  3. Drying: Pearls are partially dried to improve shelf stability.

  4. Packaging: Dried boba is vacuum-sealed for export or foodservice use.

  5. Cooking (End-user stage): Requires boiling in water for ~25–30 minutes, followed by soaking in sugar syrup.

Industrial boba production can reach 3–10 tons/day per line, depending on the factory scale.


Consumption Trends and Market Insights

  • Taiwan alone produces an estimated 100,000+ tons of tapioca pearls per year.

  • Asia-Pacific holds the largest market share (~45%), but Europe and North America are growing fastest (CAGR 7.2%).

  • Black tapioca pearls remain dominant, but popping boba and crystal boba are seeing rapid adoption in fruit-based drinks.

Are They Safe to Eat?

Commercial tapioca pearls are safe and FDA-approved when manufactured according to food safety standards. They are:

  • Gluten-free

  • Vegan-friendly (if not coated in honey)

  • Low in fat (but high in carbohydrates, ~40–70g per 100g serving)

Note: Experts do not recommend them for children under 4 years old because of choking risks.


Why This Matters for the Industry

Understanding the composition and variation of boba pearls is essential for:

  • Beverage brands and franchise buyers seeking product differentiation

  • Suppliers and exporters looking to meet international standards (e.g. ISO22000, HACCP)

  • Retailers and distributors aiming to optimize shelf life and logistics
