Food-grade activated carbons increase the shelf life of food and beverages by absorbing unwanted compounds that contribute to spoilage. These activated carbon preserve product freshness, and quality, and remove wastage. Thus, activated carbon increase consumer satisfaction.
What Are the Raw Materials for Making Food Grade Activated Carbon?
The key raw material used for manufacturing the food-grade activated carbon is a coconut shell, resin, wood, and viscose rayon. Food-grade activated carbon is used to purify liquids and gases in food & beverage processing thus many food and beverage products require activated carbon to improve purity, appearance, or other sensory characteristics. Apart from decolorization, food-grade activated carbon for removing impurities, which are typically organic compounds.
Types of Food Grade Activated Carbon
Granular Activated Carbon (GAC)
The particles of granular activated carbon are large in size, but have a smaller external surface area when compared to other types of activated carbon. GAC particles are well capable of adsorbing vapors and gasses because they disperse quickly, and are therefore often used extensively in water treatment.
Powdered Activated Carbon (PAC)
The particles of powdered activated carbon are made using ground or crushed carbon. Normally, powdered activated carbon particles are added directly to other process units, such as rapid mix basins, raw water intakes, and clarifiers. Mostly these particles are a good choice for carbon block filters.
1. Sweeteners: Remove color, taste, and odor from cane sugars, corn syrup, dextrose, and fructose.
2. Decaffeination: Caffeine removal with minimal loss of flavor and product components.
3. Deodorization: Eliminates unwanted odors in food storage and packaging.
4. Color Removal: Used to decolorize syrups, sugars, and other food products.
5. Brewing & Bottling: Purification of water, liquids and gases involved in the brewing and bottling process.
6. Acids/Chemical Purification: Decolorize and purify organic acids and amino acids from fermentation processes.
7. Water Purification: Treatment of water having stringent purity and quality requirements.
8. Vitamins: Decolorize and remove impurities from vitamins and acids during the manufacturing process.
9. Tobacco: Used in cigarette filters to remove poor taste in the smoke.
10. Beverage: Clarifies liquids and removes off-flavors in juices, wines, and other beverages.
11. Pharmaceutical Industries: It is used for decolorization, purification, and removal of impurities from chemicals, solvents, and pharmaceutical intermediates.
Can Food Grade Activated Carbon be Reused?
Once granular or pelletised activated carbons have been used for purification or decolourisation applications, they can normally be recycled by thermal reactivation enabling activated carbon to be returned to customers for reuse. Reactivation is a highly skilled process that involves treating the spent carbon in a high-temperature reactivation furnace during which the organics that have been adsorbed on the carbon in its site operation are thermally destroyed. Reactivation is a sustainable, circular economy model that enables activated carbon to be repeatedly reused in the same or appropriate application.
How to Test the Quality of Food Grade Activated Carbon?
Iodine Adsorption Test (ASTM D460)
This test checks a wet mixture of activated carbon and gives a number between 800 and 1200 mg/g. The higher the number, the better the activated carbon is at adsorbing.
Carbon Tetrachloride Adsorption Test
This test measures vapor and gives a number between 45% and 70%.
Effective Chlorine Removal
Chlorine in water isn't harmful, but it can change how the water smells and tastes. Carbons are tested to see how well they can remove chlorine. This is measured from 5 parts per million (ppm) to 3.5 ppm. A shorter time to remove chlorine is better.
Moisture Content
Test for moisture content, as excess moisture can affect performance. This is usually done using a drying oven or moisture analyzer. Lower ash content is preferable for food-grade applications.
Activated Carbon in Food and Beverage Processing: Quality and Safety Assurance
Purification and Filtration
One of the primary functions of activated carbon in food and beverage processing is purification and filtration. Activated carbon's porous structure allows it to adsorb a wide range of contaminants, including organic compounds, colors, odors, and undesirable flavors. By passing food and beverage ingredients or finished products through activated carbon filters, manufacturers can effectively remove impurities and improve product quality.
Color and Flavor Enhancement
In addition to purification, activated carbon is also utilized to enhance the color and flavor of food and beverage products. Through a process known as decolorization and deodorization, activated carbon selectively adsorbs unwanted pigments, off-flavors, and volatile compounds, resulting in a cleaner, more appealing product. This is particularly important in industries such as brewing, distilling, and juice processing, where maintaining consistent color and flavor profiles is essential.
Removal of Contaminants
Activated carbon is also used to remove contaminants and toxins from food and beverage ingredients. In the production of alcoholic beverages, for example, activated carbon is commonly employed to remove impurities such as fusel alcohols, methanol, and sulfur compounds, which can affect taste and contribute to hangover symptoms. Similarly, in water treatment for beverage production, activated carbon filters help remove chlorine, chloramines, and other chemical contaminants that can compromise product quality and safety.
Ensuring Food Safety
Beyond improving product quality, activated carbon also plays a crucial role in ensuring food safety. By removing harmful substances and pathogens from food and beverage ingredients, activated carbon helps mitigate the risk of foodborne illnesses and contamination. Its ability to adsorb mycotoxins, pesticides, and heavy metals makes it an invaluable tool in safeguarding consumer health and meeting regulatory standards for food safety.
Does Food Grade Activated Carbon Contain Additives of Any Kind?
Our activated charcoal products are certified food grade and they don't contain any sweeteners or other additives. The only ingredient is activated charcoal powder - pure carbon. It is typically made from natural sources like coconut shells or wood, and its manufacturing process aims to minimize contaminants. However, it's essential to check specific product labels or certifications for any variations.
How To Determine If Food Grade Activated Carbon Has Failed
Observe color changes
The color of expired activated carbon may change, gradually becoming lighter or brownish from its original dark black color. The color change is caused by the pores of activated carbon being filled or blocked by pollutants.
Odor change
Invalid activated carbon may produce an unpleasant odor or odor. If used activated carbon cannot effectively remove pollutants, it may release an unpleasant odor.
Decreased adsorption efficiency
The adsorption efficiency of activated carbon can be evaluated by measuring the concentration of target substances in inlet and outlet water or gas. If activated carbon fails, its adsorption capacity will significantly decrease, making it unable to effectively remove the target substance.
Time and service life
Activated carbon has a certain service life, usually determined by its design and application. If activated carbon has been used for more than the recommended lifespan or time, it is likely to have expired and needs to be replaced.
Saturation test
Specific indicators or testing devices can be used to measure the saturation of activated carbon and determine its failure. The saturation test can measure the content of adsorbed substances in activated carbon.
Several factors can directly impact the shelf life of activated carbon and its overall effectiveness. First and foremost, exposure to air is one of the primary culprits that can reduce the potency of this versatile substance.
As a highly absorbent material with a naturally porous structure, activated carbon easily attracts impurities and contaminants in the surrounding environment. Other elements such as light, humidity, and temperature variations can also significantly affect the shelf life of activated carbon.
For instance, when exposed to direct sunlight or fluctuating temperatures over an extended period, there's a possibility that its internal structure might be compromised – leading to reduced efficiency. Similarly, high humidity levels may cause clumping while promoting bacterial growth on your precious supply of activated charcoal.
