IMAG1164Garlic is well known as a natural antibiotic, shows antifungal properties and is well as a natural testosterone boosting food.

Fermenting garlic can be done with the skins on or with the cloves peeled. Cloves can change color during fermentation representing a few potential factors.

Epicurious says, “‘We don’t know a lot about this,’ says Dr. Luke LaBorde of Penn State University’s Department of Food Science. ‘It’s definitely enzymatic and nonenzymatic reactions occurring in the garlic, but we really don’t know entirely why’.” Some say this is connected to variations of different nutrients.

“The bioactivity of some natural products is increased by fermentation,” says Nutrition Research. They reported fermented garlic protected diabetic, obese mice through the antioxidant activity of the fermented garlic vs the unfermented garlic. The study showed remarkable liver support and antiobesity effects. 

Plant Foods For Human Nutrition, a publication of the Netherlands, reported a study on fermented garlic which showed, “Superoxide dismutase (SOD)-like activity, scavenging activity against hydrogen peroxide and the polyphenol content of the garlic extract were increased 13-folds, more than 10-folds, and 7-folds, respectively, as compared with those of the control garlic extract.”

They go on to say, “The fermented- garlic is suggested to possess desirable anti-oxidative properties.”

What’s specifically interesting is, as they say, “Hydrogen peroxide is generated from the scavenging reaction by SOD.”

IMAG1171Fermented garlic powder was used in a study with 144 pigs that had just been weaned. The 5-week trial showed an increase of total tract digestibility after use of the fermented garlic powder.

The Journal of Animal Physiology and Animal Nutrition reported the study concluding, “Dietary fermented garlic powder decreased the blood total cholesterol. The triglyceride concentration was decreased. Dietary fermented garlic powder can also increase the nutrient digestibility, lymphocytes and RBC concentrations, but decrease the faecal E. coli concentration in weaning pigs.”

Peeled and blanched garlic was compared with unblanched garlic during fermentation as reported by the International Journal of Food MicrobiologyThe blanched garlic was prepared by pouring boiling water over the peeled garlic for 15 minutes prior to fermentation. They reported, “The starter grew abundantly in the case of blanched garlic, producing mainly lactic acid and reaching a pH of 3.8 after 7 days, but its growth was inhibited in unblanched garlic. Ethanol and fructose, coming from enzymatic activities of the garlic, and a green pigment were formed during the fermentation of unblanched garlic, but not of blanched garlic.”

Sometimes, when fermenting garlic, the cloves change colors.

Epicurious says, “As far as they can tell, garlic enzymes—which give it that distinct flavor—break down over time. Naturally occurring sulfur in the garlic interacts with those enzymes, occasionally turning it slightly green or blue. Sometimes the color change happens, sometimes it doesn’t. Shifts in temperature, pH, and the age of the garlic can also come into play.” Older garlic turns blue or green more frequently than fresh garlic. 

The Journal of Food Science reported a study where they tested all 22 amino acids with garlic fermentation. They said, “Blue–green pigments are easily generated by mixing juice from heated white onions, a good source of 1-PeCSO (1-propenyl-L-cysteine sulfoxide) (which causes the) formation of thiosulfinates, ‘color developers’.”

They further concluded, “Green discoloration” in crushed garlic represents a mixture of yellow and blue pigments, and the blue color results from at least 8 pigments, depending on amino acid composition, rather than a single blue pigment. Results indicated that amino acids other than glycine have the potential to form blue pigments.”

The Journal of Agriculture and Food Industry posted another study testing the pigmented fermented garlic saying, ” Alliinase and acetic acid were required for the color formation. UV-vis spectral measurements and pH results suggest that the color formation occurs by two kinds of processes: one enzymatic and the other nonenzymatic.”

Some traditional cultures make Black Garlic, a totally different product than fermented garlic. Black Garlic is made by putting dried unpeeled garlic in the slow cooker on the warm setting for 12-20 days without opening the lid. This is not a probiotic food, it’s still good for you, just not a probiotic.

Probably the most telling aspect of fermented garlic is its incredible against Staph and the bacteria MRSA (Methicillin-resistant Staphylococcus aureus). MRSA that is specifically resistant to antibiotic use consistently shows no match for fermented garlic. 

IMAG1170Microbiologist and Pharmaceutical Scientist Michelle Moore says, “Unlike antibiotic drugs, garlic is very complex, containing 27 known active ingredients and dozens more that work in unknown ways. Many of these ingredients can work together synergistically inside the body in intricate ways to fight infections. The herb is highly effective against resistant MRSA bacteria because it is too complex chemically for the bacteria to become resistant to. In contrast, the antibiotic drug Zyvox, which is prescribed for many MRSA cases, has only one active ingredient: Linzolid.”

The British Journal of Biomedical Science says, “Resistance to mupirocin in MRSAs is increasing. Allicin is the main antibacterial agent isolated from garlic.” The tested garlic isolates and found, “88% of clinical isolates had MBCs of 128 microg/mL, and all were killed at 256 microg/mL. Of these strains, 82% showed intermediate or full resistance to mupirocin; however, this study showed that a concentration of 500 microg/mL in an aqueous cream base was required to produce an activity equivalent to 256 microg/mL allicin liquid.”

Fermenting garlic is one of the easiest and most potent things a person can do for their health. 

Fill a quart mason jar full of garlic cloves (peeled or unpeeled, your choice), add a tablespoon of mineral salt. Fill the jar with filtered water leaving an inch of headroom. Let the jar sit for a few weeks or longer.

  1. Dani says:

    Just be careful if you have asthma. It triggered an attack for my husband.

  2. Rachel Johnson says:

    Does a longer ferment mean it will be more potent? Another recipe says to leave it at room temp 3 days before transferring to the fridge. Which is better?

    • Becky Plotner says:

      There are a lot of factors at play here depending on the temperature, size of cloves, desire of taste. I am not aware of studies showing the length of time and effect on ferment, as of yet.

  3. So do you recommend blanching garlic before fermenting? I put it in a lot of my ferments but have not done a jar of it alone.

  4. Priscilla says:

    I have been waiting for an article like this for ages! We see so many benefits with it its unreal. Does this mean we should be blanching our garlic in hot water before fermenting it? I have never done it this way.

  5. Yes-I didn’t quite get from the information that it is better to blanche or not to blanche. Also-how many cloves a day do you eat and after several weeks-do you put it in the refrigerator? And what about the fermented garlic powder? Would it have as much benefit as the whole cloves?
    Thank you for answering-Tana

    • Mike says:

      The powder was for a controlled scientific research / blanched good for you but not probiotic / amounts ingested / as much as possible lol

  6. April short says:

    What do you do with the fermented product? Drink the juice? Use the cloves in recipes?

  7. Connie says:

    I’m in the same boat…to blanche or not to blanche, that is the question. What would a dosage for someone with MRSA be perhaps? My sister has that. And I also would like to know more about making fermented garlic powder. Dehydrate at a low temp then grind? Thanks.

  8. Rick says:

    How do you get the allicin by using fermented garlic….crush and wait 10 mins like when its raw?

What do you think?
