Can Coconut Milk Be Used to Make Yogurt? The Definitive Guide

According to research published by the University of Guam, acceptable yogurt can be produced from canned coconut milk, serving as a nutritious alternative. So, can coconut milk be used to make yogurt? This comprehensive guide will walk you through the process, from selecting ingredients to troubleshooting common issues.

Quick Summary

This article explains how to ferment full-fat coconut milk with live bacterial cultures to create a creamy, tangy, and dairy-free yogurt alternative at home. It covers the necessary ingredients, equipment, and troubleshooting for a successful homemade batch.

Key Points

• Yes, it's possible: You can use coconut milk to make yogurt, but it requires specific ingredients like a probiotic starter and often a thickener.

• Choose the right milk: For best results, use full-fat canned coconut milk and preferably just the thick, chilled cream portion.

• Mind the temperature: The probiotic cultures are sensitive; heat the milk to thicken, but cool it to 100-115°F before adding the starter to avoid killing the bacteria.

• Troubleshoot thickness: If your yogurt is too runny, try draining some of the liquid through a cheesecloth after fermenting or ensure you used a thickener.

• Nutritional differences: Coconut yogurt is lower in protein and higher in saturated fat (MCTs) than dairy yogurt, so it's not a one-to-one nutritional replacement.

• Control your ingredients: Making it at home allows you to control the sugar content and avoid artificial additives often found in store-bought versions.

The Science Behind Coconut Yogurt

The fundamental principle of making any yogurt—dairy or non-dairy—is fermentation. Lactic acid bacteria (LAB) consume the sugars in the milk, producing lactic acid, which lowers the pH. This process causes the proteins to coagulate, creating the thick, tangy consistency we associate with yogurt. However, coconut milk presents a different challenge than traditional dairy milk. Unlike dairy milk, which contains the milk sugar lactose, coconut milk contains very little natural sugar for the bacteria to consume. This means for a successful fermentation, additional sugars, like maple syrup or coconut sugar, and sometimes a thickener, must be added to provide the LAB with the fuel they need.

The bacteria used are typically freeze-dried probiotic capsules or a small amount of an existing vegan yogurt with live cultures. These beneficial bacteria, such as Lactobacillus reuteri or Lacticaseibacillus paracasei, thrive in the right conditions, creating a product rich in probiotics that can support gut health.

Step-by-Step Guide to Making Coconut Yogurt at Home

Creating your own coconut yogurt is a simple process, but requires careful attention to detail to achieve the right texture and tanginess. Using a high-quality, full-fat canned coconut milk is crucial for a creamy result.

What You’ll Need

• Ingredients
  • Two 13.5 oz cans of full-fat coconut milk (organic, chilled overnight)
  • 2-4 probiotic capsules (containing live cultures like L. bulgaricus or S. thermophilus) or 2 tbsp of a live vegan yogurt starter
  • 1 tbsp maple syrup or coconut sugar (optional, for flavor and feeding starter)
  • 1.5 tsp agar-agar powder or grass-fed gelatin (optional, for thickening)
• Equipment
  • Saucepan
  • Whisk
  • Candy or digital thermometer
  • Clean glass jar(s)
  • Cheesecloth or a thin dish towel
  • Yogurt maker or an oven with a pilot light

The Process

1. Prepare the Coconut Milk: Chill the cans of full-fat coconut milk overnight. This causes the solid cream to separate from the water. Scoop the thick, solid cream into a sterilized glass bowl, reserving the coconut water for later use.
2. Heat the Base: Gently heat the coconut cream in a saucepan over low heat until it becomes liquid, stirring to combine. If using agar-agar or gelatin, whisk it in now, ensuring it dissolves completely. Do not bring to a boil; the goal is to pasteurize, not to kill the good bacteria you are about to add.
3. Cool the Mixture: Remove the saucepan from the heat and allow the mixture to cool to a temperature between 100-115°F (38-46°C). It is critical that the temperature is not too hot, or you will kill the cultures.
4. Add the Starter: Once the mixture is in the correct temperature range, whisk in the contents of the probiotic capsules or the vegan yogurt starter. Stir gently until fully incorporated.
5. Incubate: Pour the mixture into your clean glass jar(s). Cover the jar with cheesecloth and secure it with a rubber band to allow for airflow during fermentation. Place the jar in a warm, draft-free spot. A common method is placing it in an oven with just the light on, which provides consistent, low heat.
6. Ferment: Allow the yogurt to ferment for 12 to 48 hours. The longer it ferments, the tangier the flavor will become. Check on it periodically to assess its tanginess.
7. Chill to Thicken: Once it has reached your desired taste, move the yogurt to the refrigerator. This chilling period is crucial for the yogurt to set and thicken further. If it separates slightly, simply give it a good stir.

Common Challenges and How to Troubleshoot

Making homemade yogurt can sometimes be finicky. Here’s how to address common issues:

• Runny consistency: This is the most common problem. Ensure you use full-fat coconut milk and only the solid cream portion. If it's still too thin after chilling, you can strain it through cheesecloth to remove excess water, similar to making Greek yogurt.
• Separation: It's normal for homemade coconut yogurt to separate into a cream layer and a clear whey layer, especially if your coconut milk doesn't contain added gums like guar gum. A simple stir will reincorporate the two layers.
• Not fermenting: If your yogurt lacks a tangy flavor after 24 hours, the cultures may have died. This can happen if your milk was too hot when the starter was added or if the starter culture was old. Always check the temperature carefully and use a fresh, high-quality starter.
• Off-tastes: If the yogurt smells or tastes unpleasantly alcoholic or spoiled, throw it out and start over. This can occur if the incubation temperature was too high or if your equipment wasn't properly sterilized, allowing bad bacteria to grow.

Nutritional Comparison: Coconut vs. Dairy Yogurt

Coconut yogurt is not a direct nutritional substitute for dairy yogurt, though it is a popular and healthy alternative for those with lactose intolerance or who follow a vegan diet.

Nutrient	Dairy Yogurt (e.g., Greek)	Coconut Yogurt (Unsweetened)	Key Differences
Protein	High (~9g/cup)	Low (~1g/cup)	Dairy yogurt is a significant source of protein; coconut yogurt is not.
Fat Content	Moderate, includes saturated fat (~5g/cup)	High, especially saturated fat (~8-9g/cup)	Coconut yogurt has a higher fat content, mainly saturated fat (MCTs).
Calcium	High, naturally occurring and sometimes fortified	Low, unless fortified with added calcium	Calcium content in coconut yogurt depends entirely on fortification.
Probiotics	Contains live cultures; probiotic content varies by brand	Contains live cultures, though content varies widely by brand	Both contain probiotics, but check the label for 'live and active cultures.'
Suitability	Not suitable for lactose intolerant or vegans	Suitable for lactose intolerant and vegans	Plant-based alternative for those with dietary restrictions.

Potential Health Benefits and Considerations

Despite the nutritional differences, coconut yogurt offers unique benefits. The fats in coconut milk are primarily medium-chain triglycerides (MCTs). Some studies have suggested that MCTs can offer health benefits, including boosting immunity and aiding weight management. However, it's also high in saturated fat, which should be considered in the context of your overall diet.

Furthermore, the probiotics in coconut yogurt can support a healthy gut microbiome, which is linked to various health benefits, including improved digestion and reduced inflammation. When making your own, you can control the sugar content entirely, avoiding the often-high amounts found in many store-bought, flavored yogurts.

Conclusion

Yes, coconut milk can be successfully used to create a rich, tangy, and probiotic-filled yogurt. While the process requires a few specific adjustments compared to traditional dairy fermentation, the result is a delicious and customizable dairy-free alternative. By understanding the need for high-quality ingredients, proper fermentation temperatures, and the addition of a starter culture, you can consistently produce a homemade coconut yogurt that is perfect for vegans, those with lactose intolerance, or anyone looking for a tasty plant-based option. Always remember to prioritize food safety and check your ingredients to ensure a successful and healthy batch.
