Are Strawberries Acidic? A Deep Dive into their pH Level

By Dr. Aastha Manchanda +2 more

Key Highlights: 

  • Strawberries are acidic, with a pH level typically ranging from 3 to 3.5. 
  • The acidity of strawberries is influenced by different factors, such as their ripeness and the type of cultivar.
  • Organic acids found in strawberries include citric acid, ascorbic acid, and malic acid. 
  • Acidity levels in strawberries can change based on various factors, including ripeness and whether they are frozen or fresh. 
  • While strawberries have numerous potential health benefits, their acidity may cause discomfort for individuals with acid reflux or GERD. 
     

Introduction 

Strawberries are a favourite fruit for many. They are loved for their rich aroma, bright color, and good taste. In this article, we’ll discuss if strawberries are acidic. We’ll discuss their pH levels and the organic acids present in them. We’ll also discuss how their acidity affects our health. Lastly, we will answer the frequently asked questions regarding this topic.  

Understanding pH and Acidity 

Before we talk about the acidity of strawberries, we need to understand what pH and acidity all mean.  

are strawberries acidic

What is pH? 

pH tells about the “potential of hydrogen.” It measures how much hydrogen ions are there in a solution. Simply, it shows how acidic or basic a substance is. The pH scale ranges from 0 to 14. Every number on the scale tells us about the acid or base levels. For example, a pH of 3 means it’s ten times more acidic than a pH of 4. Acidity pulls the pH down while alkalinity pulls the pH up.  

Defining acidity and alkalinity 

Acidity relates to substances that produce hydrogen ions (H+) in solutions. Alkalinity, on the other hand, refers to substances that produce hydroxide ions (OH-) in solutions. So, an acidic solution has more hydrogen ions, and an alkaline one has more hydroxide ions. 

pH scale and its relevance 

The pH scale runs from 0 to 14. 0 is highly acidic and 14 is very basic or alkaline. The neutral pH is 7. Acidic substances typically have a pH between 0 and 6.99. Alkaline substances have a pH between 7.01 and 14. This scale is used in a lot of areas. It helps in checking soil conditions for farming, water quality, and the acidity or alkalinity levels in our food and drinks.

Are Strawberries Acidic? 

Now that we understand pH and acidity, we can now try to understand if strawberries are acidic. In this section, we’ll discuss the acidity of strawberries, the factors affecting it, and the types of organic acids present in these fruits. 

1. The acidity level of strawberries 

Yes, strawberries are acidic. They usually have a pH ranging from 3 to 3.5. In comparison to lemons,  which have a pH of 2.2 to 2.4  strawberries are less acidic. But, it’s this acidity that gives the strawberries their unique taste. 

  • Factors affecting the acidity of strawberries  

 All strawberries don’t have the same acidity level. Not exactly. Several factors can change their acidity level. These factors can be the type of strawberry, growing conditions, and how ripe they are. Even different types of strawberries can taste different due to these reasons. 

  • Variability in types and cultivars 

Different types of strawberries can have varied acidity levels. This is because each type comes with its own set of features and tastes. Some strawberry types might be more acidic than others leading to stronger tart flavours. 

2. Types of organic acids found in strawberries 

Strawberries have a few types of organic acids. They add to the fruit’s acidity and give it its unique flavour. The acids found in strawberries include citric acid, ascorbic acid, and malic acid. Each of these acids plays a special role in giving strawberries their taste and health value. 

  • Citric acid 

Citric acid gives strawberries their tart taste. It’s like what you taste in citrus fruits. But citric acid doesn’t just bring  flavour. It also acts as a natural preservative and keeps strawberries fresh for longer. 

  • Ascorbic acid 

Strawberries are a great source of vitamin C or ascorbic acid. This acid helps to keep our body healthy. It aids in the growth and repair of tissues. It also works as an antioxidant to protect our cells from damage. 

  • Malic acid 

Strawberries also have malic acid. Its presence goes down as the strawberry ripens. This change in malic acid levels changes the taste of strawberries as they ripen.  

3. How does the level of acidity change in strawberries? 

The acidity level in strawberries can change. It depends on how ripe the fruit is and how it’s stored. 

  • Unripe strawberries vs. ripe strawberries 

When strawberries are not ripe yet, they are hard and pale. They also taste tart or even sour due to high acidity. As they ripen, they turn soft and bright red. Their taste also changes as they become sweet and less acidic. But it’s not just the taste that changes. The texture, smell, and nutritional content also change. For example, ripe strawberries have more vitamin C than unripe ones. 

  • Frozen vs. fresh strawberries 

There’s not much difference in the acidity level between fresh and frozen strawberries. Freezing the berries doesn’t change their acidity level. But if they are kept frozen for very long, they might taste more acidic. Even then, you can use them in all of your  favourite recipes and pair them with sweet foods to balance out the acidity. 

Potential Health Benefits and Possible Adverse Effects of Eating Strawberries 

Even though strawberries are f healthy, they might not be the best for everyone. Especially, if you have acid reflux or GERD.  

1. Source of Vitamin C 

You know already that strawberries are a great source of vitamin C. A cup of strawberries can give you about 140% of the daily need for vitamin C. That’s around 85mg of vitamin C. 

2. Antioxidant properties 

Strawberries don’t only have vitamin C. They are also packed with a lot of antioxidants. These help control harmful free radicals in your body. These antioxidants may help you maintain heart health and balance blood sugar levels. 

3. Dietary fiber 

Strawberries are also a good source of dietary fiber. Fibers are said to assist in digestion and help keep your heart healthy. Strawberries are low in calories so you can snack on them without worrying about too much calorie intake. 

4. Tart flavor and sugar content 

The acidity in strawberries gives them a tart taste which pairs well with their natural sugars. This unique sweet and tart taste is what makes strawberries so loved. But, it’s best to eat strawberries in moderation due to their sugar and acid content. 

Potential adverse effects for acid reflux and GERD patients 

Strawberries might not be the best for everyone. If you have acid reflux or GERD, their acidity might cause issues. They could make your symptoms worse leading to discomfort. So, if you have a sensitive stomach, it’s a good idea to ask a healthcare professional before adding acidic fruits like strawberries to your diet. 

Ripeness and Acidity 

How ripe a strawberry is can change its acidity level. Ripe strawberries tend to be less acidic than unripe ones.  

As strawberries ripen, they become sweeter and less acidic. All these changes impact the taste, texture, aroma, and nutrition of the fruit. So, if you want the best balance of sweet and tart, go for fully ripe strawberries. Also, picking fully ripe strawberries can help avoid any discomfort from their acidity. 

Tips for selecting ripe strawberries 

Here are some tips for picking ripe strawberries. 

  •  Look for a deep red colour all over the berry. If they have green or white parts, they are not ripe yet. 
  • The top leaves of ripe strawberries should be green and fresh. If they look wilted or brown, the strawberry might not be ripe. 
  • Try to softly squeeze the strawberry. Ripe ones will feel firm but give in a little. They should not be very soft or mushy. 
  • Ripe strawberries give off a sweet smell. 

Consumption Tips 

If eating strawberries causes discomfort, you don’t have to quit them. Here are some ways to reduce their acidity and continue enjoying them. 

  • Can you make strawberries less acidic? 

You can balance out the acidity of strawberries by eating them with alkaline foods. If you are making a smoothie with strawberries, try using unsweetened almond milk. It’s alkaline and might help reduce the effect of the strawberry’s acid. 

  • Incorporating strawberries into a balanced diet 

Here are some tips to eat strawberries without feeling discomfort. 

  • Like all foods, only eat strawberries in moderation. 
  • Combine strawberries with non-acidic or alkaline foods like yogurt, oatmeal, or almond milk it helps reduce the acidity of strawberries. 
  • As we talked about before, ripe strawberries are less acidic than unripe ones. So, try to pick fully ripe strawberries to avoid any discomfort. 
  • Pairing strawberries with less acidic fruits 

If eating strawberries alone is hard for you, pair them with fruits that have low acidity. Bananas, melons, and mangoes are such fruits. When eaten together, these can balance out the tartness of strawberries while mixing different flavours. 

Comparing Strawberry Acidity with Other Fruits 

1. Are strawberries more acidic than oranges? 

Oranges have a pH ranging from 3.3 to 4, making them slightly more acidic than strawberries. But both are still considered low in acidity. 

2. Are grapes or strawberries more acidic? 

Grapes are more acidic than strawberries. Their pH ranges from 2.9 to 3.4.  

3. Are strawberries more acidic than lemons? 

Yes, strawberries are more acidic than lemons. Lemons have a pH of 2.0 to 2.6, making them a lot more acidic than strawberries.  

4. Classifying fruits by their acidity 

Let’s list some fruits based on their acidity levels: 

  • Low-acid fruits: Bananas, melons, mangoes 
  • Medium-acid fruits: Strawberries, oranges, nectarines 
  • High-acid fruits: Grapes, lemons, pineapples
