Immune Boosting Orange Peel Puree

Orange peel puree for boosting immune strength to protect against influenza and virus infections.


When we think of the nutrition in oranges, we tend to think of the vitamin C content that benefits our immune systems.

But oranges also contain valuable antioxidants for protecting our health, and most of them are found in orange peels.

Orange peel nutrients are widely studied for their potential to prevent disease and virus infection, promote heart and gut health, aid digestion, reduce allergies, and calm inflammation.

Orange peels offer a wide range of powerful compounds produced by plants that provide health benefits to your body (phytonutrients).


Orange peels offer a wide range of powerful compounds produced by plants that provide health benefits to your body (phytonutrients).

They are full of antioxidant flavonoids, predominantly hesperidin.

Hesperidin is known to have antioxidant • anti-inflammatory • antiadipogenic (lowers high levels of fats) • antiallergic (prevents or relieves allergies) • anticarcinogenic (protecting against cancer) • antiviral • insulin-sensitising • hypolipidemic (decreases high cholesterol) • neuroprotective (defends the central nervous system against injury) • and vasoprotective (alleviates or prevents blood vessel diseases) properties.

We should never underestimate the power of nutrition to protect our health.

In cold and flu seasons, orange peels offer us a simple way we can prevent and heal from flu and virus infections.

And you can make eating orange peels delicious using my puree recipe.

I’ve included links in the reference list to studies that show hesperidin’s anti-viral activity against the influenza virus by significantly reducing the ability of a virus to infect your cells (virus replication).

Hesperidin is also emerging as a promising candidate in the fight against COVID-19 (SARS-CoV-2), with the potential to contribute to both preventive and therapeutic strategies.

This orange peel puree recipe aims to help you boost and protect your metabolism and immune system.


I originally created an orange peel puree recipe to use for myself to help prevent and recover from viruses, colds and flu infections.

I’m constantly working with sick people so I use proactive strategies to protect my immune system.

Now, with virus infections challenging us all year round, I want to share my puree recipe with everyone because it’s powerful and delicious.

It’s a prevention is always the best cure type of recipe you can eat daily.

The aim of the recipe is to help you boost and protect your metabolism and immune system.

You use a slow cooker for this recipe to preserve as much nutrition as possible.

But you can also gently boil whole oranges, and we give you that option in the recipe.

Luckily, the citrus season in Australia peaks in the colder months of winter so there are plenty of oranges to choose from.

Navel oranges are available throughout winter. They are a sweet, seedless orange making them ideal for orange peel puree.

I make small batches of orange peel puree at a time but feel free to adjust the recipe quantities to suit your needs.


4 organic oranges.

1/2 cup boiling water.

1/4 cup lemon juice.

1/2 teaspoon cinnamon.

1/2 teaspoon of 100% pure monk fruit powder.

3 tablespoons of dark, organic, pure maple syrup.


Slow cooker – on low.

Stick blender.

Metric measuring spoons.

Glass storage jars.


If you can’t source organic oranges, thoroughly wash your oranges with detergent or a sonic cleaner to remove any wax or pesticide residues. Do not remove the peel.

Cut the oranges in quarters and then finely slice each quarter and remove any seeds.

Layer the orange slices in your slow cooker.

Pour half a cup of boiling water in a glass measuring jug.

Add the cinnamon and monk fruit.

Whisk the ingredients into the hot water.

Stir in the lemon juice.

Pour over the oranges.

Set your slow cooker on slow heat for 3-4 hours.

After 2 hours stir the fruit, bringing the bottom layers to the top, and press the fruit into the juices.

After three hours check to see if the peels can be easily softened with a fork.

If not completely cooked, continue cooking for four hours, turn the cooker off, take the lid off, and allow to cool.

When cooled to room temperature, add the maple syrup to offset the bitterness of orange pith.

Then get your stick blender and blend into a smooth orange puree.

Taste test and add more maple syrup if needed.

Pour your purée into sterilised glass jars and store in the fridge.

Because this recipe doesn’t contain preserving sugar, make sure you eat the puree within two weeks.

Recipe notes for swapouts and alternative ingredients.


I use a 1.5 litre slow cooker with a ceramic inner pot and glass lid for this recipe. You may need to adjust the cooking time if you use more oranges or a large slow cooker.

The oranges are cooked when the peels easily break up with a fork.

If you don’t have a slow cooker, you can boil the oranges using the same recipe. Bring to the boil, then reduce the heat and gently simmer with the lid on the pot for one to two hours. Keep the lid on the pot and allow the cooked oranges to cool to room temperature before blending.

I love eating blood oranges, which you can see in the recipe image, but use whatever is in season, and preferably a sweet orange variety.

If you can’t source organic oranges, make sure you scrub them well to remove as much pesticide and wax residue as possible.

Orange peel puree made in a slow cooker creates a stronger brew than boiling oranges. But use what equipment you have. Either way of cooking will benefit your gut microbiome and immune system.

The amount of pure maple syrup sweetener you add will depend on the variety and number of oranges you use. Taste test and sweeten accordingly. Don‘t use sugar.

If you can’t source 100% pure monk fruit, don’t worry – it’s a natural sweetener with immune-boosting benefits. Just add maple syrup after the oranges are puréed.

I buy 100% pure monk fruit powder online from Herbal Connection in Queensland.

And also I use Thankfully Nourished pure liquid monk fruit extract, which I stock at the clinic to help my clients quit sugar.

If you can’t source 100% pure certified organic maple syrup, use raw honey. Add the honey once your cooked oranges have cooled so you don’t destroy the enzymes in the honey.

There are many ways you can enjoy eating orange peel puree.


There are many ways you can enjoy eating orange peel puree.

Have fun experimenting and find your favourite way.

You can eat 1 teaspoon of orange puree three times daily straight off the spoon to boost your metabolism and immune system and prevent chronic disease.

Add 1 tablespoon of orange purée to 3 tablespoons of coconut yoghurt. Avoid animal dairy products if you are congested with phlegm.

If you can’t source plain, live coconut yoghurt, add one tablespoon of orange puree to plain Greek yoghurt. Only use a live, plain yoghurt without fillers – they offer beneficial friendly bacteria that aid your gut health and digestion.

Add 1 tablespoon of orange puree to a mango and banana smoothie. Also, see our Healthy Gut Reboot or Gut Health Boosting Smoothie Recipe blogs for health-boosting smoothie ideas.

Add a tablespoon of puree to individual coconut chia puddings.

Add a tablespoon of orange puree to your cooked porridge.

Add 1-2 teaspoons of puree to a cup of lemon balm tea to soothe lung congestion.

Add a tablespoon of orange peel puree to fruit salad.

Add 1-2 teaspoons of orange peel puree to a delicious hot cacao drink with saffron honey to soothe coughing.

Slow cooking makes orange peels more palatable. But for even greater nutritional value, you could also zest raw orange peel and add it to yoghurt, smoothies, salads, in dairy-free cream cheese frosting, or as a topping for porridge or desserts.

You can also add a tablespoon of raw orange peel to fresh juices. Try fresh pineapple, carrot, orange peel, and ginger juice to alleviate coughing.

JUICE CAUTION: pineapple is not recommended if you are pregnant or take blood thinning medication. Use organic apples instead.
