Citric Acid Vs Sodium Citrate: What Are They & What Roles Do They Play?

Citric acid vs. sodium citrate, what exactly are these two compounds, and what roles do they play? Frequently encountered as co-additives in beverages, there exists a pervasive inquiry regarding their safety for consumption. We will give a comprehensive exploration of these queries in the following text.

What's Citric Acid?

Citric acid comes in natural and man-made flavors. You can find natural citric acid all over the place—in fruits like lemons, oranges, and pineapples, and even in animal bits like bones, muscles, and blood. Man-made citric acid, on the other hand, is whipped up from sugary stuff like sugar, syrup, starch, grapes, and more.

Loads of fruits and veggies, especially the citrusy ones, pack a punch of citric acid. Lemons and limes, for instance, are chock-full, with up to 8% when dried (that's about 47g/L in juice). Among citrus fruits, citric acid levels range from 0.005 mol/L in oranges and grapes to 0.30 mol/L in lemons and limes.

Citric acid is a friendly edible acid that boosts our normal body processes and doesn't harm us when we consume it sensibly. It even lets jazz up things like jams, drinks, canned goods, and candies to make them tastier. But because it can mess with how our bodies handle calcium, folks who gobble down a lot of canned foods, drinks, jams, and sour candies, especially kids, should keep an eye on their calcium intake.

What's Sodium Citrate?

Sodium citrate, on the other hand, is a natural compound that looks like white or clear crystals. It plays nice with water and glycerol, sort of okay with ethanol, and adds a dash of mild alkalinity to water, giving it a cool, refreshing taste. Heat it up to 100°C, and it turns into a dihydrate salt. It's the most important salt of citric acid, born when starch-like stuff ferments into citric acid, which then gets cozy with alkaline substances.

Sodium citrate has good water solubility, excellent chelating capacity for metal ions such as Ca2+ and Mg2+, biodegradability, strong dispersing ability, and anti-redepositing ability. Therefore, it is used as a raw material to produce various specialized detergents for cleaning copper kitchenware, valuable precision instruments, as well as for pesticide residue removal on vegetables and fruits.

And in the world of cosmetics, sodium citrate fights skin pigmentation, boosts skin condition, speeds up skin renewal, helps get rid of dark spots, shrinks pores, and clears out blackheads.

Citric Acid vs. Sodium Citrate: What happens when they combine?

Now, back to the duo: as we mentioned before, citric acid brings sourness and pH control to the party, while sodium citrate adds a hint of saltiness and a touch of alkalinity. Though they're both acids, they're pretty different.

When you mix them, they team up to create a buffer system that keeps the pH level in check. This teamwork softens citric acid's sour punch, making it less intense and giving it a long-lasting, balanced vibe. Together, they make jams, jellies, juices, drinks, ice-cold sips, dairy treats, and pastries that taste better and stay stable.

Most of the time, citric acid can do its thing solo, but adding a pinch of sodium citrate helps mellow it out, so it doesn't overpower your taste buds, making your treat taste more natural and subtle.

In addition, in the world of drinks, keeping things stable is a big deal. That's where sodium citrate comes in, helping maintain the right pH. It's because lots of stuff can't handle too much acidity, and some drinks have proteins that are picky about pH levels. Sodium citrate keeps everything in harmony.

In a Nutshell

Citric acid vs. sodium citrate, these two buddies boost the taste, stability, and flavor of all sorts of food and drinks. They are both proven to be non-toxic, so they are absolutely safe to consume. If you want to manipulate these two chemicals yourself at home to achieve a perfect recipe, you may want to pay attention to their ratio, 1:2 was experimented with is feasible, but you can also try other options - but remember, don't eat their mixture straight away, it's very risky-! -until there is experimentation.
