What are the edible straws at Tropical Smoothie made out of?

Tropical Smoothie Cafe has recently introduced edible straws as an eco-friendly alternative to plastic straws. These innovative straws provide the convenience of a straw without the waste and harm to the environment. But what exactly are these magical straws made of?

The Problem With Plastic Straws

Plastic straws have become a major source of plastic pollution and waste. Americans use over 500 million plastic straws every single day, with the majority ending up in landfills and oceans. Plastic straws are one of the top 10 contributors to marine plastic pollution. Once in the ocean, they are extremely damaging to marine life and ecosystems.

There is a growing movement to reduce or eliminate plastic straw usage. Many cities and companies are banning plastic straws or switching to compostable or reusable options. Tropical Smoothie Cafe’s edible straws are part of this positive change towards more sustainable practices.

The Composition of Tropical Smoothie’s Edible Straws

Tropical Smoothie Cafe’s edible straws are made from a gluten-free flour blend, often using ingredients like wheat flour, tapioca flour, and potato starch. They do not contain any gluten, nuts, dairy, or genetically modified organisms (GMOs).

The exact flour blend varies, but generally consists of:

  • Wheat flour
  • Tapioca flour
  • Potato starch
  • Rice flour
  • Cornstarch

These flours form a dough that can be shaped into straws and baked. The straws have a slightly sweet, neutral flavor profile. Their texture is crisp initially but softens as it absorbs the beverage.

The Production Process

Producing the edible straws involves a fairly straightforward process:

  1. Mixing the flour blend with water to form a dough
  2. Extruding the dough into long tubes to form the straw shapes
  3. Baking or dehydrating the straws to set their structure
  4. Cooling and packaging the finished straws

The straws are shaped to have the thickness and flexibility required to function as drink straws. The baking process dehydrates them enough to make them sturdy and crisp initially. Their neutral taste allows them to accompany any beverage.

Edibility and Flavor

The straws are completely edible and safe to ingest. As they absorb liquid, their texture softens and becomes closer to a doughy or bread-like consistency. The wheat flour provides a slightly sweet, bready flavor. Overall the straws themselves have a fairly mild, neutral taste.

Tropical Smoothie Cafe designed them to complement their fruit smoothies and other cold beverages. The straws absorb and carry the flavor of the beverage. Customers can simply eat the straw after finishing a smoothie or juice for a little extra treat.

Nutritional Profile

Since they are made from gluten-free flour, the straws provide some nutritional value. Their analysis per straw is approximately:

Nutrient Amount
Calories 35
Carbohydrates 7 g
Fiber 0.5 g
Fat 0 g
Protein 1 g

The straws provide a small boost of carbohydrates and fiber. Since they are baked and low fat, they make a healthier snack than other starchy foods like donuts or cookies. They can help provide a little extra energy from the wheat flour carbs.

Environmental Sustainability

The edible straws are designed to be compostable and much lower impact than plastic straws. Consumers can compost the straws along with any food waste rather than sending them directly to landfills.

Some key environmental benefits include:

  • Renewable plant-based ingredients
  • Compostable and biodegradable
  • Reduce plastic waste and pollution
  • Lower carbon footprint than plastic

Edible straws align with Tropical Smoothie Cafe’s sustainability initiatives to be more environmentally responsible. They demonstrate how businesses can innovate to reduce waste and plastic consumption.

Cost Analysis

There are a few factors that contribute to the cost of producing edible straws versus plastic straws:

  • Ingredients – Edible straws require gluten-free flours and water, while plastic straws use petroleum-based polymers like polypropylene. Flour ingredients generally cost more than plastics.
  • Manufacturing – The baking process for edible straws consumes more energy and labor than plastic extrusion. However, plastic also requires significant energy for extraction and refining of fossil fuels.
  • Transportation – Edible straws are heavier than plastic, so shipping costs are slightly higher.
  • Packaging – Both straw types require protective packaging for transport and to maintain freshness.

Overall, edible straws cost 2-5 times more than plastic straws. However, as demand increases and recipe optimization continues, the manufacturing and supply chain costs can decrease. And the environmental benefits provide significant added value not captured by monetary cost alone.

Customer Responses

Customers have responded positively to the edible straws at Tropical Smoothie Cafe. They appreciate the opportunity to reduce plastic waste. Many people find it fun to eat the straws. Kids in particular enjoy the novelty.

Some key customer feedback themes include:

  • Happy to ditch plastic straws
  • Straws have a pleasing sweet taste
  • Fun experience for kids
  • Straws start out crispy but soften with the drink
  • Neutral flavor doesn’t clash with the beverages

Negative feedback has been minimal. Some customers don’t like the texture change as the straws soften and prefer straws that remain crispy. Individuals allergic to wheat cannot consume the straws. However, the overall response has been extremely positive.

The Future of Edible Straws

Edible straws are still a relatively new concept but are gaining widespread popularity. As more companies like Tropical Smoothie Cafe adopt them, they will continue to grow in availability and affordability.

Some expected future trends include:

  • More specialty straw shapes and flavors
  • Custom branded straws for individual businesses
  • Increased durability and lifespan
  • Lower costs through scaled production
  • Broader use beyond foodservice in venues like airlines and hotels

Edible straws provide a functional, safe, and environmentally sustainable solution. They satisfy consumers’ desire for straws while reducing waste and pollution. They are a simple innovation with massive potential positive impact. Tropical Smoothie Cafe’s edible straws are an exciting step towards a world less dependent on single-use plastics.


Tropical Smoothie Cafe’s edible straws provide a tasty and eco-friendly alternative to plastic straws. They are produced from a gluten-free flour blend, often containing wheat flour, tapioca flour, potato starch and other ingredients. The straws are formed using an extrusion process, then baked to set their shape and crisp texture. They have a mild, sweet flavor that absorbs the taste of the beverages they are used with.

The edible straws are biodegradable and compostable, unlike their plastic counterparts. They have been met with an overwhelmingly positive response from Tropical Smoothie Cafe customers seeking more sustainable options. While the straws currently cost more to produce than plastic, advances in manufacturing and supply chain efficiency can lower expenses over time. Edible straws offer an easy way for businesses to reduce their plastic waste and environmental footprint.
