Why Are Gummies Acidic? Discover the Role of Acids in Gummy Manufacturing

Are you wondering why gummies have that delightful tang? It’s all thanks to the acids used in the gummy production. But what’s the science behind this, and why are gummies acidic? Well, acids play a significant role during gummy manufacturing. Understanding how different acids influence the overall gummy texture, taste, and shelf life is the secret to crafting irresistible gummy treats. So, whether you’re a small, medium, or large-scale gummy-making business, this guide is for you. Let’s dive in.    

.

How important are acids to gummy making?

Acids are crucial additions to your gummy recipes to ensure the final product is a delicious and appealing gummy treat. Here are the two primary reasons why gummy manufacturers use acids during production: 

• Flavor enhancement 

Acids like citric, malic, and tartaric provide a tangy and tart dimension or sour taste in gummies. They elevate the gummy fruity notes and complement their sweetness. This enhances the overall gummy taste experience. Therefore, your choice of acid can significantly impact the gummy taste, making it essential to select the right acid based on the desired flavor profile.

• Gelling process 

Acids are essential for activating gelling agents and setting the gummy texture, especially in pectin-based recipes. They interact with the pectin molecules, forming a network that gives the gummies their structure and characteristic chewiness. The pH level of the gummy mixture is crucial for this process. If the pH is too high, the pectin may not gel properly, resulting in gummies that are too soft or runny. Conversely, if the pH is too low, the gummies may become overly hard and brittle.  

Gummy manufacturers can find dealing with acids challenging due to their influence on pH and setting time. The addition of acids can lower the pH of the gummy mixture, which can affect the gelling process and the overall texture. 

We recommend the following tips to ensure optimal gelling and texture in acidic gummies: 

• Use a pH meter to measure the pH of the gummy mixture and adjust it as needed.
• Carefully control the amount of acid added to the mixture to avoid excessive pH changes. 
• Combine different acids to help balance the pH and achieve the desired flavor profile. 
• Be familiar with the properties of the pectin being used. Various types of pectin may have varying pH requirements.

How are acidic gummies produced? 

The production of acid gummies is a precise and intricate operation that you can achieve in the following key steps.

.

.

Step 1: Compounding

The first step in manufacturing acidulated candy is weighing, mixing, and cooking. 

1. Weighing: You should use calibrated scales to carefully weigh all the raw materials for your gummy recipe, such as sugar, gelatin, corn syrup, acidulants, flavoring, and colorants.  

2. Mixing: After you have the correct weight for each raw material, use a high-speed mixer to thoroughly combine the ingredients to form a homogeneous syrup. The mixing time and speed can be adjusted based on the specific acid gummy recipe and desired texture.

3. Cooking: Heat the syrup to a temperature of approximately 140-150°F (60-65°C), which is crucial for activating the gelatin and ensuring proper gelling. The cooking period can vary depending on the gummy-making recipe and the desired consistency.

Step 2: Forming gummy

Once you have the gummy syrup, it is time to mold your final gummy products.

1. Depositing: This step requires you to deposit the gummy syrup into gummy layouts and molds to shape the gummy treats into the desired forms. With a gummy depositing machine from GummyGenix, you can produce solid, stripped, or layered gummy treats. 

2. Cooling: Now, pass the gummies deposited in your gummy molds through a cooling tunnel with a controlled temperature of around 50-60°F (10-15°C). This allows the gummies to solidify and set in their respective shapes without becoming too hard. 

3. Demolding: After cooling, remove the acid gummies from the molds. Use a demolding machine from GummyGenix to gently remove the gummies without damaging them. 

.

Step 3: Quality control

The last step is to ensure your acidic gummies meet the desired size and shape specifications with no visual defects such as cracks, air bubbles, or uneven surfaces. You must also measure the acid concentration in the gummies using a pH meter to check the tartness level. Substandard gummies are removed, and the final products are packaged. 

If you want to establish a fully or semi-automatic gummy production line for your business, the following equipment from GummyGenix is essential!

Acids like ascorbic acid (Vitamin C) can extend the shelf life of gummies by acting as preservatives, preventing oxidation, and maintaining freshness. However, the type and concentration of acid must be carefully controlled to avoid compromising the gummy texture and taste over time. The pH level also plays a crucial role in preventing microbial growth, which can further enhance shelf life.

.

8. Can the pH of gummies affect their color and flavor stability?

Yes, the pH of the gummy mixture can significantly affect both color and flavor stability. A lower pH (more acidic environment) can cause colorants and flavors to degrade or change over time, especially if natural colorants or delicate flavors are used. Maintaining an optimal pH balance helps preserve the intended color and flavor profile throughout the product’s shelf life.

.

9. What are the most effective methods for incorporating acids into gummy recipes?

To ensure optimal texture and flavor, it is crucial to add acids at the right stage of gummy production. Acids should generally be added after cooking to prevent premature gelling and ensure even distribution throughout the mixture. Start with a small amount, and gradually adjust while monitoring the pH with a meter. Additionally, use a pre-dissolved acid solution to achieve a uniform taste and avoid localized over-acidification. Combining different acids can help balance the overall flavor profile and prevent unexpected texture changes.
