How to Make Black Garlic: A Complete Guide to Commercial Black Garlic Production

Black garlic is not the same as having fresh garlic until it turn black during the process. The quality of the final product is determined by the careful control of the raw material, temperature and humidity, fermentation period, and drying period.  For Black Garlic Manufacturers, commercial production is a process of managing controlled conditions to produce black garlic, rather than following a simple cooking recipe.

Commercial buyers require repeatability, consistent moisture levels, appropriate packaging, and a production system that allows for frequent deliveries.

1. Start With the Right Fresh Garlic

Raw garlic is the starting point of production, as fermentation cannot rectify poor-quality bulbs. The commercial processors typically choose mature, plump, undamaged, unbruised garlic without visible mold or damage. It may also be determined by the product that is to be manufactured.

When appearance and dense and premium presentation are crucial, the choice may be for solo or single-clove garlic. For cost sensitive applications and further processing, multi-clove garlic may be more convenient. Rich Garlic cooperates with the Yunnan single-clove garlic and Shandong garlic in various applications of black garlic.

The garlic must be well sorted, after which it should be cleansed and air dried until there is no surplus surface moisture before the fermentation. Standardization also aids batches in responding to controlled conditions in a uniform way.

2. Prepare the Garlic for Controlled Fermentation

After the raw garlic has been graded and cleaned, it goes into a special fermentation machine. For commercial production, the garlic is fermented at a relatively high temperature. The temperature and the relative humidity should be kept in the controlled range for a longer period.

Rich Garlic claims that it is a 60-90°C temperature & 70-90% humidity and typically takes 90-120 days in its stepped dry-fermentation process. The profile parameters can be modified for the desired product properties and production specifications.

The key is consistency. Temperature and humidity should be controlled throughout the batch rather than treated as fixed values. Black garlic needs time to grow, and this can be influenced by heat, humidity, and speed.

3. Monitor What Happens During Black Garlic Fermentation

It's a natural chemical and enzymatic change that's responsible for the transformation, not added coloring. The garlic darkens, softens and sweetens during a prolonged fermentation period due to enzymatic reaction and the Maillard reaction.

The pungent flavor of fresh garlic diminishes over time. Changes in the proteins and carbohydrates in garlic also contribute to its sweet-and-sour taste and soft texture.

When it comes to commercial scale, there is a need to keep track of the batch, since the results won't be the same if the same equipment is used. The product's flavor can be affected by the temperature, humidity, length of fermentation, characteristics of the raw garlic and moisture.

Quality control should be used to compare the final batch with established specifications for color, texture, odor and moisture. This provides a repeatable process and not just based on appearance.

4. Control Moisture After Fermentation

Fermentation does not constitute the last step in production. Once the garlic is at the desired blackness, aroma and texture, it must be vented and dried.

The production process of Rich Garlic results in an end product with less than 35% moisture. Solutions are available to enhance the storage stability and to package the product. Drying should be controlled; if cloves are too dry, they become unduly hard, and if they are not sufficiently dried, there is a decrease in storage stability.

Manufacturers can inspect this point to see if the size, appearance, and texture are consistent and remove any that do not meet standards for packing.
 

5. Grade, Test, and Package the Finished Product

After the garlic is sufficiently firm, it may be graded and conditioned for the desired market. There are various forms in which commercial black garlic is sold and the grading and packing will depend on the application.

Whole bulbs, peeled cloves, paste, powder, and extract can be used in a variety of food and ingredient applications. The packaging should correspond with the shape of the product, the required shelf life, the mode of shipment, and the sales.

Jars or smaller pack sizes can be used for retail products, and larger bulk sizes can be preferred for bulk buyers. Dried black garlic to be stored for a longer period can also be vacuum-packed.

Quality checks should include issues of concern to the purchaser, including appearance, moisture, microbial status and appropriate food-safety requirements. Documentation and market-specific certifications may also be included in the specification for international trade.

6. What Makes Commercial Production Different From Home Fermentation?

Home fermentation is about producing a usable batch. Commercial production needs to ensure hygiene, moisture control, packaging and delivery specifications and provide a consistent product over a number of runs.

The commercial fermentation chamber enables operators to keep track of the conditions in a larger volume of garlic. It is crucial when providing distributors, food processors, restaurants or private label brands that require consistent specs from one shipment to the next.

Some helpful questions for buyers choosing a black garlic manufacturer are: Where is the garlic grown, How is the garlic fermented? What is the level of moisture needed? What form of garlic are they available in, What kind of tests are done to check the quality, What are the options for the packaging, What is the minimum order quantity, and Can they customize the garlic? This information may tell us more than just the question of how long garlic is fermented.

7. How Can the Process Be Customized for Different Markets?

Different buyers require different black garlic. A retail snack might be more interested in appearance, sweetness, texture, and convenient packaging, whereas a food manufacturer may be more interested in the cost, consistency, and suitability for sauces, seasonings, or processed products.

Technical specifications of commercial processors can be modified to use different raw material types, garlic sizes, fermentation times, moisture, product form, and packaging. Rich Garlic offers whole and single-clove black garlic as well as peeled, paste, powder, and extract forms for different applications.

If a new product line is being launched, sampling prior to mass production is feasible for buyers. It provides both sides an opportunity to verify colour, texture, taste, moisture, packaging and other specifications before a big order is made.

Conclusion

The secret to the commercial production of black garlic involves not just extended heat, but controlled transformation. It begins with fresh garlic, followed by controlled temperature and moisture, to the end of drying, inspection, grading and appropriate packaging.

Consistency is the most crucial lesson for manufacturers and importers. A commercial process should have the necessary consistency in terms of producing the product in the desired shape, texture, flavor, moisture, and color from batch to batch. With those specifications in hand, it's a much easier task to determine the production methods and suppliers.
