TelegramFruit juices contain many organic acids in varying proportions. These acids can include oxalic acid, citric acid monohydrate, citric acid anhydrous, malic acid, lactic acid, and ascorbic acid.
The proportion of these substances in fruit juice depends on the juice's content and the type of fruit.
To determine the quantities of organic acids, the reverse-phase UPLC method is used. This is a chromatographic separation method. Potassium dihydrogen phosphate is used as a buffer in the mobile phase.
The factors that change the organic acid profiles are as follows;
- Sweet Orange
- White Apple
- Red Apple
- Lime
- Lemon
- White Grapefruit
- Pink Grapefruit
The presence of the fruits above is a determining factor for which organic acid will be present.
From this, it is understood that organic acids exist in fruits and vegetables. They can be obtained through the fermentation of fruits and vegetables. And these organic acids are actively used in many foods during the manufacturing process. Organic acids are obtained from foods through water and solvent extraction, followed by a steam distillation process, and then precipitation to separate them from other elements and substances like lead.
How Are Organic Acids Obtained from Fruits and Vegetables?
Industrially, the most common extraction method for these substances is solvent extraction.
The amount of organic acid to be obtained from fruits and vegetables via extraction is determined by the fruit's maturity level and geographical origins.
What Are the Effects of Organic Acids in Fruits on Human Health?
The organic acid compositions found in fruit have an impact on the sensory properties for humans. This creates a particular demand for citrus products.
Scientific studies have shown that the consumption of citrus juices has positive effects on coronary patients and chronic asthma sufferers.
At the same time, extracts of citrus fruits have the ability to prevent specific issues, exhibiting antioxidant, anti-inflammatory, anti-tumor, anti-fungal, and blood clot prevention properties.
Citrus fruits are known as acidic fruits. Because their composition consists of organic acids and sugars.
The main acids in citrus fruits are as follows;
Among these, malic acid is used to provide a sour taste. It has a very high souring capability.
What Are Organic Acids and Their Uses?
Citric acid balances the pH of the fruit juice and acts as a preservative. Tartaric acid increases the clarity of the fruit juice and acts as a preservative. Ascorbic acid acts as an antioxidant and extends the shelf life of the fruit juice. Fumaric acid and lactic acid enhance the aroma of the fruit juice and act as preservatives.
