    Lacto-Fermentation - What Is It?

    FacebookTweetPinShares558

    Lacto-Fermentation is a great way to get probiotics into your diet. It is an important part of the GAPS diet and also a great way to get beneficial probiotics into your diet.

    You might think of it like pickling but it is not pickling in the traditional sense as in store-bought pickles. Let's see how they are different.

    Fermented foods shown on counter with cutting board.

    You may have noticed my latest recipe additions - Sauerkraut and Fermented Carrots - contain fermentation in the process.

    Being on the GAPS Diet and reading about the health benefits of probiotics, I have purposefully added them to our family's diet.

    One way to get probiotics is through fermented foods. But, not just "fermented" as in pickled, I mean "fermented" using the lacto fermentation process.

    So, what is lacto fermentation and why is it so healthy?

    The result of lacto-fermentation is the proliferation of lactobacilli. They increase the vitamin levels and make the fermented foods more digestible.

    These beneficial bacteria, lactobacilli, produce helpful enzymes. Antibiotics and anti-carcinogenic substances help with the process too.

    Lactic acid is the main by-product of lactobacilli and has two important jobs:

    1. It helps preserve vegetables and fruits.
    2. Promotes the growth of healthy flora (or bacteria) throughout the intestines.

    Lactic acid is a natural preservative that inhibits bacteria which putrefies.

    Vegetables and fruits contain starches and sugars. They convert into lactic acid by the lactic-acid-producing bacteria.

    There are many species of these bacteria. Lactobacilli in particular is present on all living things. Encouraging this one to grow, has great health benefits!

    Please keep in mind that this is a very specific type of fermentation. Not every fermentation recipe will use lacto-fermentation.

    Lacto-fermentation Simple, Yet Complicated

    The Weston A. Price Foundation (a wonderful source for information about food and natural processes in general) says this about the history of lacto-fermentation:

    The ancient Greeks understood that important chemical changes took place during this type of fermentation. Their name for this change was “alchemy.” Like the fermentation of dairy products, preservation of vegetables and fruits by the process of lacto-fermentation has numerous advantages beyond those of simple preservation.

    The proliferation of lactobacilli in fermented vegetables enhances their digestibility and increases vitamin levels. These beneficial organisms produce numerous helpful enzymes as well as antibiotic and anticarcinogenic substances. Their main by-product, lactic acid, not only keeps vegetables and fruits in a state of perfect preservation but also promotes the growth of healthy flora throughout the intestine. Other alchemical by-products include hydrogen peroxide and small amounts of benzoic acid.

    History of Lacto-fermentation 

    Again from the Weston Price Foundation: 

    A partial list of lacto-fermented vegetables from around the world is sufficient to prove the universality of this practice... Cucumbers, beets and turnips are also traditional foods for lacto-fermentation. Less well known are ancient recipes for pickled herbs, sorrel leaves and grape leaves. In Russia and Poland one finds pickled green tomatoes, peppers and lettuces. Lacto-fermented foods form part of Asian cuisines as well.

    The peoples of Japan, China and Korea make pickled preparations of cabbage, turnip, eggplant, cucumber, onion, squash and carrot. Korean kimchi, for example, is a lacto-fermented condiment of cabbage with other vegetables and seasonings that is eaten on a daily basis and no Japanese meal is complete without a portion of pickled vegetable. American tradition includes many types of relishes–corn relish, cucumber relish, watermelon rind–all of which were no doubt originally lacto-fermented products. The pickling of fruit is less well known but, nevertheless, found in many traditional cultures. The Japanese prize pickled umeboshi plums, and the peoples of India traditionally fermented fruit with spices to make chutneys.

    Lacto-fermentation - 3 Ingredients

    Basically, the lacto-fermentation process uses 3 simple ingredients:

    1. Good quality produce - Good quality produce provides the nutrients necessary for the lactobacilli to work.
    2. Sea salt - Sea salt inhibits the growth of putrefying bacteria until enough lactic acid is produced.
    3. Water - provides the liquid necessary for growth and maintaining an oxygen free environment.

    You can keep vegetables for many months once a sufficient amount of lactic acid is produced through the lacto-fermentation process.

    People use fermented food starters, kefir or whey to "jump-start" lactic-acid producing bacteria's growth. They help to make the fermentation process more consistently successful.

    Lacto-fermented vegetables are nutritious and the fermentation process enhances the nutritional profile making the nutrients more easily absorbed by the body.

    Why Is Lacto-fermentation Not Used for Large Scale Production?

    This process is not used on a large scale by bug business - why not? The answer is simple.

    The lacto-fermentation process did not yield consistently predictable results when converted to an industrialized process.

    Uniform products, speed and profit are the goals of businesses. However, while the pickles products available in today's stores are produced consistently, the result is not a more nutritious one.

    Examples would be the addition of vinegar and pasteurization. This kills all the lactic acid producing bacteria which benefit the digestive system)

    Important Points About Lacto-Fermentation

    When using recipes I have posted which use the lacto-fermentation process, as well as any others you might find, remember a couple of important things:

    1. Lacto fermentation is an anaerobic process. Once fermentation begins, the presence of oxygen will affect your results. For example: If you do not have something weighing the cabbage down below the surface of the liquid, you should push it down into the liquid using a clean spoon, morning and evening. Mold grows on any surfaces exposed to air. Scoop this out and thrown away—it's easy. The remaining sauerkraut will be just fine. But, if your fermented vegetables taste or smell rotten - throw them out and start over. I have made many batches of both sauerkraut and fermented carrots and only one batch of sauerkraut went awry. There was no question that something was wrong and I threw it out and started over!
    2. The vegetables will expand slightly and may even become bubbly during the fermentation process. Make sure to leave a 1 inch space between the top of the vegetables and the top of the jar.

    Some brands of lacto-fermented vegetables are available through health food stores, however, they tend to be rather expensive. Like these pickles and pickles which you may find locally for less.

    Since I enjoy the adventure of learning and trying new recipes, I have loved this new way of preserving. Cooking should always feel like an adventure!

    Your gut health plays a central role in nutrient absorption, and affects all other systems in your body. The bacterial cultures in your intestines are an often overlooked and neglected part of the average diet.

    Known as the "second brain", your gut has more than 100 million neurons, and needs to be nourished.

    You'll find recipes here that focus on prebiotic ingredients, whole vegetables, and probiotics like kefir, sauerkraut and cheese.
