Microorganisms play a crucial role in transforming raw ingredients into consumable and flavorful food products. Here’s how they contribute:
1.Fermented Foods
A)Cheese and Yogurt: Specific bacteria like Lactobacillus and Streptococcus species are used in the fermentation of milk. They produce lactic acid, which coagulates the milk proteins, forming cheese and yogurt.
B)Bread and Beer: Yeasts, such as Saccharomyces cerevisiae, ferment sugars to produce carbon dioxide (for bread leavening) and alcohol (in beer and wine production).
2.Probiotics
Gut Health: Probiotics are live bacteria (e.g., Lactobacillus and Bifidobacterium) added to products like yogurt or capsules. They promote a healthy gut microbiome, improving digestion and immunity.
3.Pickling and Sauces
Foods like pickles, kimchi, and soy sauce rely on microbial fermentation. These processes enhance flavor, texture, and shelf life.
Benefits of Microbial Involvement in Food
Prolong shelf life through natural preservation.
Enhance nutritional value by producing vitamins (e.g., B12) and digestible proteins.
Develop unique flavors and textures.
