Understanding Citric Acid: Uses, Benefits, and Safety

Understanding Citric Acid: Uses, Benefits, and Safety

From sparkling sodas to tangy cocktail mixes, citric acid is the secret sour weapon that makes many of our favorite beverages sing. This common yet powerful organic acid naturally occurs in citrus fruits, giving lemons, limes, and oranges their characteristic bite. Today, it’s added to both natural and artificial beverages to stabilize, preserve, and balance flavors. But how did citric acid go from fresh fruit to manufacturer-made ingredient? Is it a natural compound or lab-created chemical? Most importantly, is citric acid considered safe for regular consumption in drinks? Read on as we explore the origins, uses, safety, and science behind citric acid additions in beverages.

What is Citric Acid?

When it comes to citric acid, the name tells you a lot. It's an acid that's found naturally in all kinds of citrus fruits - think lemons, limes, oranges, and grapefruit. This sour stuff is what gives these fruits their tart, zingy taste. The chemical name is a mouthful, but you probably know citric acid best as the ingredient that makes sour candies, fizzy sodas, and tangy cocktail mixes taste the way they do. It's produced commercially in powder form from fermented sugars and used to give foods that lip-puckering flavor. Citric acid does more than make your mouth water though. It acts as a preservative too, helping keep foods fresh and safe. The sour taste comes from citric acid stimulating receptors on your tongue that say "tart stuff here!" to your brain. That tingling sensation is your cue that whatever you're eating or drinking contains this common acid. It's found in all living things, especially fruit, so citric acid is a totally natural ingredient. While too much can be bad for your teeth, it's considered safe when used properly to enhance flavors.

How's that? I tried to explain what citric acid in a conversational way that is easy to understand. Let me know if you would like me to clarify or expand on anything!

The Powerful Benefits of Citric Acid in Beverages

Citric acid offers several advantages that make it an invaluable component in many popular prepared drinks. Let’s explore some of the top benefits:

Preservative properties

One of the most important benefits of citric acid is its ability to act as a natural preservative in beverages. The low pH environment created by citric acid inhibits microbial growth from bacteria and fungi, allowing drinks to stay stable and safe for consumption. Citric acid also chelates metal ions that can catalyze damaging oxidative reactions during storage. This antioxidant effect further delays spoilage. With proper acidification, pasteurization, and bottling, beverages can maintain quality and freshness for months.

Flavor enhancement

In addition to preservation, citric acid brings out the bright, vibrant flavors in beverages. It stimulates taste receptors on the tongue, allowing people to better detect sweetness and tartness. Citric acid enhances fruit-based flavors like berry, citrus, and tropical flavors by making them “pop”. It also balances out unpleasant bitter notes common in iced tea, coffee, and chocolate drinks. This flavor boost makes beverages more palatable and craveable.

pH control

Citric acid gives beverage manufacturers better control over the acidity level in their products. Drinks need sufficient acidity for microbial stability, but also an appealing pH for taste. Citric acid allows precise pH adjustment between 3-4 for the optimal balance. This pH also ensures the best solubility and stability of other ingredients like vitamins, minerals, and antioxidants.

Clean, tart taste 

Consumers expect that brisk, lip-puckering sensation from certain beverages. Citric acid provides that clean, tart flavor without dulling other tastes. It has a neutral background that doesn’t overpower like vinegar or affect color like lemon juice. The crystallization also makes it easier to control tartness. This makes citric acid ideal for achieving the right zing.


Unlike other acids like phosphoric or lactic acid, citric acid works well in a huge range of beverage types. It can be used in carbonated soft drinks, still fruit beverages, powdered mixes, alcoholic drinks, coffee and tea products, or functional waters. This versatility makes it a staple across the entire beverage industry.

What Citric Acid Commonly Used For?

One of the most prevalent uses of citric acid is as an additive and preservative in prepared foods and beverages. Within the beverage industry, citric acid is widely utilized in carbonated soft drinks, juices, ready-to-drink cocktails, flavored waters, iced teas and coffees, and more. Even small amounts of citric acid can help stabilize the pH, boost flavor, and prevent spoilage in these products. Beverage manufacturers often include citric acid in their formulations because of its ability to act as a natural preservative. The low pH environment created by citric acid prevents microbial growth and inhibits chemical reactions that lead to degradation. This allows companies to limit the use of artificial preservatives in their products. Citric acid also balances out sweeteners, enhances fruit flavors, and adds tartness to counter the bitter notes in coffee and tea. It provides the brisk, refreshing quality consumers expect in many mainstream beverages. Whether it's the burst of tartness in lemon-lime soda or the slight puckering quality in an iced tea, citric acid is likely contributing that signature tang behind the scenes. It's an unsung workhorse ingredient that delivers both flavor and functional benefits in all types of ready-to-drink beverages.

Is Citric Acid Safe and Natural?

When it comes to citric acid, naturalness and safety go hand in hand. Unlike synthetic chemicals, citric acid is a pure organic substance that occurs abundantly in nature. It's found in the cells of virtually every plant and animal species as part of the Krebs cycle that generates cellular energy. Humans have safely consumed citric acid in fruits and foods since the dawn of time. Common citrus fruits offer some of the highest natural concentrations. With modern production methods, manufacturers can now take advantage of citric acid’s benefits safely and sustainably. The citric acid used in foods and beverages today is commercially fermented from carbohydrate sources like corn in a process similar to brewing beer. After purification, the end product is chemically identical to the citric acid found in an orange or lemon. The FDA and food regulatory agencies worldwide affirm citric acid as GRAS (Generally Recognized as Safe). When used according to food manufacturing guidelines, citric acid poses no health risks. In fact, citric acid offers a healthier alternative to artificial ingredients for flavor and preservation. With a long history of safe use and natural origins, citric acid has rightfully earned its place as an invaluable component of the modern food and beverage industry.

Who Can Use Products Contain Citric Acid?

When it comes to citric acid in drinks, moderation is key for most individuals. For healthy adults, beverages containing citric acid can be safely enjoyed as part of a balanced diet. The tartness from citric acid makes these drinks more palatable and refreshing. Consuming citric acid from natural sources like juices or from additive amounts in carbonated beverages, flavored waters, teas, and coffees is not a concern for most people. These products can be incorporated into the daily diet without issue when citric acid is within the safe usage limits for the beverage type. 

Those sensitive to acidity, such as those with GERD or ulcers, may want to monitor intake of highly acidic drinks. 

People taking medications that interact with citric acid or those with kidney stone tendencies may also require caution with chronically high intakes. 

However, citric acid is recognized as safe for healthy pregnant and breastfeeding women at recommended dosages spaced throughout the day. 

Children can also safely enjoy citric acid-containing drinks occasionally provided serving sizes account for lower body weight. 

Overall, beverages flavored and preserved with citric acid pose no increased health risks compared to their homemade counterparts containing fresh citrus juice. With some common sense precautions for special populations, citric acid can be safely used to create enjoyable drinks for everyday consumption.

Citric Acid Dosage and Use

When it comes to citric acid, a little goes a long way. Here are some guidelines for safe use:

  •     Up to 0.5% solution for flavor balancing. This works out to about 500 mg citric acid per 100 ml of total beverage.
  •     Up to 1% solution for preservative effects. Use 1000 mg citric acid per 100 ml of beverage to help control microbial growth.
  •     Limit straight citric acid powder to 500-1000 mg servings. Measure carefully to avoid overconsumption.
  •     Consider dilution, solubility, and impact on other ingredients. Citric acid can potentially interact with proteins, leach minerals, and damage surfaces.
  •     Store in an airtight container away from moisture and sunlight to prevent caking.

Start with small amounts of citric acid and increase to the lowest effective dose for purpose. This will provide an ideal tangy flavor and sufficient preservative effect.

Why Citric Acid for our CBD Cocktails?

Complement the hemp flavor

The earthy, botanical taste of hemp can be quite strong on its own. Citric acid helps brighten up and complement the grassy, funky flavors of our full spectrum hemp extract. It rounds out the herbal notes in ingredients like lemon balm, hibiscus, and ginger, allowing their flavors to shine through instead of getting muddled by the hemp. The interplay keeps our CBD flavor vibrant instead of one-dimensional.

Preserve potency

One of the biggest challenges with CBD-infused beverages is maintaining stability and potency during storage. The nanoemulsified CBD we use provides great bioavailability but can still degrade over time. Citric acid helps create an inhospitable environment for the chemical reactions that cause CBD to degrade. The low pH and chelating properties inhibit oxidation, hydrolysis, and other breakdown reactions. This keeps our CBD intact so it delivers the full impact we intended when you crack open a can, even months after canning.

Add complexity

Citric acid is essentially a flavor multiplier in Jeng CBD cocktails. It interplays with the fruit juices, sugars, spices, and hemp extract to create a symphony of satisfying flavor. Rather than just tasting tart, sweet, or hempy, the acids create a cascading tasting experience that dances on your tongue. This multidimensional flavor experience is part of what makes our drinks so interesting yet approachable. The citric acid is key to that profile.

Let the CBD shine 

Poorly formulated CBD drinks often use strong flavors like fruit juices or spices to mask the taste of lower quality hemp. The flavor experience ends up being one-dimensional. With our high purity CBD extract, we don't want to hide or overpower its essence. Citric acid lifts up those terpenes and plant compounds. The tartness makes you salivate, allowing the true nuances of the hemp to shine through. You get its full impact.

Make flavors pop

In many beverages, flavor molecules can get buried or muddled. Citric acid helps punch them through, especially in carbonated drinks. The bubbles, juices, spices, and hemp pop with each sip rather than falling flat. It's like an instant flavor explosion in your mouth. That bright, lively mouthfeel keeps you coming back for more. The citric acid creates an addictive and consistent experience.

Keep drinks stable

One of the challenges of canned CBD cocktails is maintaining stability without using preservatives. Citric acid allows us to create shelf-stable recipes that stay fresh until you're ready to enjoy them. Its antimicrobial properties and pH buffering inhibit spoilage reactions. And its chelating power prevents oxidative damage. This ensures every sip tastes just as fresh as the day it was canned, even months later. You can stock up knowing the quality will be locked in.

Wrap Up

While citric acid is only a minor part of any beverage, its impact is major. This versatile organic acid helps today’s drinks stay stable, safe, and deliciously tart. From fruit-flavored sodas to ready-to-drink cocktails, citric acid offers both functional benefits and flavor enhancement. It replaces the need for less natural preservatives and lets natural fruit flavors shine. For most consumers, enjoying citric acid in moderation poses little health risk and adds enjoyment to everyday beverages. Next time you crack open a cold one, appreciate the science behind that thirst-quenching tang. Citric acid may work quietly, but its powerfully tart punch keeps us coming back sip after sip.
