Sour taste is one of five major taste qualities perceived by humans, along with salty, sweet, umami (savoury) and bitter [].Nearly all (or perhaps even all) modern human cultures employ microbes in ways that make foods that are not sour become more sour [], and the preparation of such sour ferments pre-dates the origins of agriculture [3,4].
Fermented foods are defined as “foods or beverages produced through controlled microbial growth, and the conversion of food components through enzymatic action” . Many foods have historically undergone fermentation, including meat and fish, dairy, vegetables, soybeans, other legumes, cereals and fruits.
Fermented foods are packed with probiotics, which are beneficial bacteria that can aid in digestion and boost the immune system. Some fermented foods also contain essential vitamins and minerals, such as vitamin K and vitamin B12. Additionally, fermented foods can help to lower cholesterol and improve heart health.
