What Is Spirulina?

Spirulina is a nutritious alga popular for its health benefits and culinary potential.

This blue-green algae are abundant in freshwater environments in tropical and subtropical regions.

Did you know?

Spirulina owes its vibrant green color to chlorophyll, a natural pigment found in plants. This pigment is responsible for the characteristic hue of spirulina-containing products.

When added to foods or beverages, spirulina imparts a noticeable green hue, which can range from a lighter green shade to a more intense, deep green color.

It thrives in alkaline bodies of water, forming dense colonies or mats. Harvesting spirulina involves collecting and filtering them from these aquatic sources.

Today, spirulina is commonly available in different forms. The most common forms include powder, tablets, and capsules.

Spirulina powder is versatile. You can easily add it to smoothies, energy bars, baked goods, and savory dishes.

Tablets and capsules provide a convenient option. People who want to take spirulina as a dietary supplement prefer these forms.

If you’re looking to boost your nutrition or experiment with new flavors, spirulina is a great ingredient to consider.

Spirulina Types

There are two main types of spirulina: green and blue spirulina. Aside from their color, the main difference is their composition.

Green spirulina is the whole alga, the whole food.

Blue spirulina, on the other hand, is an extract from the whole food. In short, blue spirulina comes from the green one.

If you want to buy spirulina, look for it in grocery stores with an extensive health food aisle. Better yet, try your luck in health or natural food stores. You may also find it in specialized online retailers.

Choose high-quality and organic spirulina from reputable brands to ensure its purity.

What Does Spirulina Taste Like

Green spirulina offers a unique taste profile with its earthy and grassy notes.

It will remind you of freshly cut grass or seaweed.

You’ll also get a subtle bitterness that adds depth to its taste. Lastly, what you can’t miss is its umami flavor.

Did you know?

Spirulina has a distinct taste that can be described as earthy, slightly salty, and somewhat seaweed-like.

Note that the taste can vary depending on the quality, source, and processing methods.

Some powders may even exhibit hints of sweetness. In that case, the sweet notes will counter the earthiness.

Spirulina’s unique taste adds a touch of character and contributes to its appeal. Its taste attracts food enthusiasts seeking to explore new flavors.

Blue spirulina powder, on the other hand, has a milder, more neutral taste. For this reason, most people prefer it to the green one.

Still, many consider spirulina an acquired taste regardless of its color.

How Does Spirulina Taste In Smoothies?

When added to smoothies, spirulina can contribute a unique taste that may be described as earthy, slightly seaweed-like, or grassy.

The flavor of spirulina can vary depending on the specific brand and the other ingredients in the smoothie.

One of the best ways to consume spirulina is to add it to smoothies. This way, the other ingredients in your smoothie will mask the taste of spirulina.

The result is a refreshing and earthy beverage with a nutrition boost. Not to mention, your drink will also have a vibrant green or blue hue.

For the best outcome, pair spirulina with ingredients with a strong flavor. It will also help if you use it in small amounts.

How To Make Spirulina Taste Good

You are not alone if you cannot stand the taste of spirulina. It is an acquired taste, after all.

The good news is that there are things you can do to make spirulina taste good.

Start with Small Amounts

If you’re new to spirulina, it is best to start by adding small amounts to your recipes. This technique allows you to adjust.

Over time, you’ll get used to the taste and not think it tastes bad anymore.

Mask with Strong Flavors

Combine spirulina with ingredients that have strong flavors to mask its taste.

Combining it with citrus fruits or sweet ingredients can help mask or balance its taste.

Pair it with cacao powder, vanilla extract, citrus juice, or spices like cinnamon or ginger.

These ingredients have much stronger flavors than spirulina. That said, you may not even taste spirulina at all.

Mix with Creamy Ingredients

Another way to make spirulina taste better is to pair it with yogurt, coconut milk, or nut butter.

Their creaminess will help mellow its earthy taste and make it more palatable.

Add Natural Sweeteners

Of course, you can never go wrong with adding a sweetener to improve the taste of spirulina. So as not to counter its health benefits, it is best to use natural sweeteners.

Opt for agave nectar, honey, or maple syrup to balance the taste.

Experiment with Recipes

Don’t hesitate to experiment with different recipes to find what works best for you. Spirulina is versatile enough to meld well with lots of other ingredients.

Try various combinations until you find the mix that you like.

Buy High-Quality Spirulina

Most of the time, spirulina’s strong and fishy taste is because of poor quality.

To ensure that you get the best-tasting spirulina, buy from reputable sources. This way, you’ll have your hands on high-quality, non-fishy spirulina.

Spirulina Storage And Shelf Life

The best way to keep spirulina is to store it in the fridge. However, since it is in powder form, you should keep it away from light, moisture, and air.

Place it in an airtight container and keep it away from liquids. Avoid using transparent containers to protect the powder from light.

While spirulina itself cannot be frozen, you can incorporate spirulina into recipes or preparations that are suitable for freezing.
