What is the pH of orange juice?

In this brief blog, we will address the query,”What is the pH of orange juice?” We will also look at the importance of measuring pH in fruit juices. We will talk about the nutritional value of orange juice and fresh oranges. We will also discuss some health benefits of orange juice.

What is the pH of orange juice?

The pH of orange juice ranges between 3.30 and 4.15 and this depends on the type of the orange , where it has been cultivated and how it is processed. 

The acidity of foods and beverages is usually rated on a scale that ranges from 0 to 14 that depicts the highest acidity (0) to the highest alkalinity (14). If a food or drink falls rates in the middle which is a pH of 7 it is considered to be neutral and is neither acidic nor alkaline.

What is the importance of measuring the pH of fruit juices?

pH is a very important parameter to measure in fruit juices as it affects the shelf life and spoilage rate of the fruit juice. Another factor that also determines the shelf life is the water activity. 

Variations in the pH of a fruit juice can affect the flavor, consistency and also the shelf life of the product. Most fruit juices have low pH values that range from 2.0 to 4.5 because of the presence of organic acids that usually differ in the various fruit juices.

So as to monitor the quality of fruit juices it is essential that you monitor the pH and ensure that it is in the required range that does not encourage microbial growth which is generally acidic.

What is the nutritional value of orange juice?

The nutritional value of fresh oranges and orange juice is very similar although there are some notable differences. One major difference is that orange juice has less dietary fiber and also about twice the calories and carbohydrates which are the fruit sugars.

Let’s take a look at a comparison of the nutrients typically contained in 240 ml of orange juice and a medium orange weighing 131 grams which are both one serving of a fruit.

What are some health benefits of orange juice?

It is rich in antioxidants

Antioxidants are very powerful compounds that help prevent oxidative damage by neutralizing any free radicals in the body and have been shown by studies to help protect against chronic diseases such as cancers.

Numerous studies have also shown that antioxidants are important for general health and prevent conditions such as cancer as mentioned previously, heart disease and even diabetes.

Orange juice is a great source of antioxidants such as flavonoids, carotenoids and also Vitamin C (Ascorbic acid)

It can strengthen your immune system

Orange juice is a great source of Vitamin C with a cup of orange juice providing twice the Recommended dietary Intake. Vitamin C aids in boosting your immune system and can help fight some conditions such as the common cold.

It can help prevent kidney stones

Kidney stones are small hard deposits which are made up of minerals and salts that form inside the kidneys as a result of excess body weight, diet, some medical conditions and some medications.

Kidney stones can result in symptoms such as severe pain, nausea and blood in the urine. Studies have shown that an alkaline pH in the urine may be effective in preventing kidney stones.

Orange juice can assist in increasing the pH in urine and thus making it more alkaline.

It can help reduce the risk of birth defects

The folate that is present in orange juice can assist in healthy fetal development. Pregnant women are advised to take in at least 400 mcg of folate or folic acid per day so as to prevent neural tube defects.
