Where Does Citric Acid Come From?

Hold on to your taste buds; until the early 1900s, citric acid was derived as it was back in 1784, from lemons, then researchers discovered black mold. Black mold efficiently converts sugars into citric acid, and its fermentation is generally recognized as safe by the FDA under its Federal Food, Drug, and Cosmetic Act. Approximately 99 percent of the world’s manufactured citric acid powder production is developed from the Aspergillus niger fungus, also known as black mold.

Citric acid has a fascinating history when it comes to its sources of production. Up until the early 1900s, citric acid was primarily derived from lemons, as first demonstrated by Carl Wilhelm Scheele in 1784. However, a significant breakthrough occurred when researchers discovered the remarkable citric acid-producing abilities of a particular strain of fungus known as Aspergillus niger, commonly referred to as black mold.

The discovery of black mold as a highly efficient producer of citric acid revolutionized the commercial production of this compound. Today, approximately 99 percent of the world’s manufactured citric acid powder is derived from the cultivation and fermentation of Aspergillus niger. This strain of fungus possesses a unique enzymatic pathway that enables it to convert sugars into citric acid through a process known as fermentation.

The citric acid production using Aspergillus niger involves a carefully controlled and monitored fermentation process. Carbohydrate-rich substrates, such as molasses or cornstarch, are provided as a food source for the fungus. Under specific conditions of temperature, pH, and oxygen availability, the fungus metabolizes the sugars in the substrate and produces citric acid as a metabolic byproduct.

This fermentation process occurs in large-scale bioreactors, where the growth of Aspergillus niger is carefully controlled. The fungus is cultivated on a bed of solid substrate or in a liquid medium containing the carbohydrate source. Citric acid accumulates in the fermentation broth as it grows and metabolizes the sugars.

Once the fermentation process is complete, the citric acid-containing broth undergoes a series of purification and separation steps. These steps typically involve filtration, precipitation, and acidification to isolate and purify the citric acid. The final product is a high-quality citric acid powder ready for use in various industries.

It is important to note that the use of Aspergillus niger for citric acid production has been extensively studied and deemed safe by regulatory authorities such as the U.S. Food and Drug Administration (FDA). The FDA recognizes the production of citric acid by this fungus as Generally Recognized as Safe (GRAS) under its Federal Food, Drug, and Cosmetic Act.

In summary, while citric acid was initially derived from lemons, the discovery of black mold, specifically Aspergillus niger, as a highly efficient producer of citric acid revolutionized its commercial production. Today, the vast majority of manufactured citric acid powder is obtained through the controlled fermentation of Aspergillus niger. This fungus has a unique ability to convert sugars into citric acid, making it an indispensable source for the global production of this compound.

Tips for the BEST Wine Slushies;

1. Select your wine: Choose a wine that complements the flavors you desire in your slushie. Popular choices include fruity and crisp wines like Sauvignon Blanc, Riesling, Rosé, or even a sparkling wine like Prosecco. Opt for a wine with a flavor profile that pairs well with the added tanginess.
2. Add fruit: To enhance the fruity flavors in your slushie, consider adding fresh or frozen fruits of your choice. Common options include berries (such as strawberries, raspberries, or blueberries), peaches, mangoes, or citrus fruits like lemons or limes. The natural acidity in these fruits will complement the citric acid addition.

Drink Responsibly:

Remember to enjoy your wine slushies responsibly and be mindful of alcohol consumption. The addition of citric acid can elevate the overall taste experience, adding a tangy and refreshing twist to your homemade wine slushies. Cheers!

How to make your own Citric Acid mask:

Making a citric acid face mask can help brighten the skin, promote a healthy complexion, and provide gentle exfoliation. However, it’s essential to note that citric acid is an acid, so it’s crucial to use it in the correct proportions and conduct a patch test beforehand to ensure your skin can tolerate it.

Here’s a simple recipe to make a citric acid face mask:

Ingredients:

• 1 tablespoon citric acid powder
• 2 tablespoons water or aloe vera gel
• 1 tablespoon honey (optional)
• 1-2 drops of essential oil (such as lavender or tea tree oil, optional)

Instructions:

1. Start by thoroughly cleaning your face with a gentle cleanser and patting it dry.
2. In a small bowl, combine 1 tablespoon of citric acid powder with 2 tablespoons of water or aloe vera gel. Mix well until the citric acid is dissolved.
3. If desired, you can add 1 tablespoon of honey to the mixture. Honey has moisturizing and antibacterial properties that can benefit the skin. Mix until all the ingredients are well combined.
4. Optional: Add 1-2 drops of your favorite essential oil to the mixture. Essential oils can add fragrance and additional skin benefits, but be sure to choose oils that are suitable for your skin type and dilute them properly.
5. Apply the mask to your face, avoiding the eye and lip areas. You can use clean fingertips or a soft brush to spread an even layer of the mask.
6. Let the mask sit on your face for 10-15 minutes. You may feel a slight tingling sensation, but if it becomes uncomfortable or causes irritation, rinse off the mask immediately.
7. After the designated time, gently rinse off the mask with lukewarm water. Ensure that all traces of the mask are removed.
8. Pat your face dry and follow up with your regular skincare routine. Apply a moisturizer to keep your skin hydrated.

Note: It’s essential to use caution when using citric acid on your face. Citric acid is an exfoliant and can be too harsh for sensitive skin or if used in high concentrations. If you have sensitive skin or any underlying skin conditions, it’s best to consult with a dermatologist before using a citric acid face mask.

Remember to perform a patch test before applying the mask to your face to check for any adverse reactions. Discontinue use if you experience redness, irritation, or discomfort.

Something You Shouldn’t Clean With Citric Acid

While citric acid is generally safe and effective for many cleaning purposes, there are certain items or surfaces that you should avoid cleaning with citric acid.

Here are a few examples:

1. Natural Stone Surfaces: Avoid using citric acid on natural stone surfaces such as marble, granite, limestone, or travertine. The acidic nature of citric acid can etch or damage the delicate surface of these stones.
2. Aluminum: Citric acid can react with aluminum and cause discoloration or even corrosion. It’s best to avoid using citric acid on aluminum surfaces or items.
3. Cast Iron Cookware: Citric acid can strip the seasoning off cast iron cookware. It is recommended to clean cast iron with gentler methods to preserve its seasoning and prevent rust.
4. Certain Metals: While stainless steel is generally safe to clean with citric acid, some other metals like copper, brass, or bronze may be sensitive to acidic cleaners. Citric acid can cause tarnishing or damage to these metals.
5. Electronics and Electrical Appliances: Avoid using citric acid on electronics, electrical appliances, or any item with delicate electronic components. The moisture and acidity of citric acid can cause damage to these items.
6. Porous Surfaces: Citric acid should not be used on porous surfaces such as unglazed tiles, grout, or untreated wood. The acid can penetrate and damage these porous materials.
7. Sensitive Fabrics: Citric acid can have a bleaching effect on certain fabrics, especially delicate or colored fabrics. It’s best to avoid using citric acid on fabrics unless you have tested it on a small, inconspicuous area first.

Remember, it’s always important to read and follow the manufacturer’s instructions for cleaning specific items or surfaces. If in doubt, perform a patch test in an inconspicuous area before using citric acid on a larger scale.
