What is Fermentation?
Fermentation is one of the oldest and basic forms of preserving food. Fruits and vegetables contain natural bacteria that, when deprived of air, can suppress and inhibit the growth of other microbes that would cause spoilage. During the fermentation process, these natural bacteria convert the carbohydrates and sugars in food to an acid which creates an ideal environment for preserving. Lacto-fermentation, a process brought on through the presence of lactobacillus, gives fermented foods and drinks their signature tangy and sour taste, but also creates probiotics that aid digestion.
Due to their health benefits, fermented foods such as kimchi and sauerkraut have become increasingly popular in recent years. Making fermented foods at home is a cheap and healthier alternative to shop bought products and allows you to experiment with new and exciting flavours.
