Lemon has many bioactive components such as citric acid, Ascorbic acid, minerals, flavonoids and essential oils (5). Citrus essential oils are generally recognized as safe (GRAS) and a complex mixture of about 400 constituents consisting of 85-99% volatile and 1-15% non-volatile components (6)..
Herein, what are the chemicals present in lemon?
The chemical composition of lemon juice apart from water is contains certain acidic substances called citric acid and carboxylic acid (Saidan et al., 2004, Silalahi, 2002).
Additionally, what is the chemical formula for lemon juice? Citric acid has the chemical formula C6H8O7, and the catchy systematic name of 2-hydroxypropane-1,2,3-tricarboxylic acid. If you look at the molecule you can see why it's an acid.
Also know, what are the chemical properties of lemon juice?
One of the primary chemical properties of lemon juice is its low pH. With a highly acidic pH level of 2, lemon juice lies just below stomach acid on the pH scale. Lemon juice's high acidity means that it has a high concentration of hydrogen ions. Like other acidic substances, lemon juice is sour and can corrode metals.
What is the main component of lemon juice?
The juice of the lemon is about 5% to 6% citric acid, with a pH of around 2.2, giving it a sour taste. The distinctive sour taste of lemon juice makes it a key ingredient in drinks and foods such as lemonade and lemon meringue pie.
