Study Notes
Industrial Microbiology
- Industrial microbiology is a branch of applied microbiology that uses microbes to produce important products such as metabolic manufactures, biotransformation, energy, and management of organic and industrial wastes.
- Microbial food processing is used to transform simple food into value-added forms and convert low-value, often inedible, perishable natural resources into high-value, safe food products.
Microorganisms
- Microorganisms, or microbes, are organisms that are microscopic.
- The study of microorganisms is called microbiology.
- Microorganisms can be bacteria, fungi, archaea, or protists.
- The term microorganisms does not include viruses and prions, which are generally classified as non-living.
- Microorganisms from yeasts, bacteria, and fungi are useful to humanity and have a major contribution in the food industry.
Mechanism of Microorganisms in Food Industry
- Microbes produce food products through fermentation, which is the biochemical change of simple sugars into favorable products such as alcohol, acid, and carbon dioxide.
- Fermentation processes improve the taste, aroma, and shelf life of products at low cost.
Applications of Microorganisms in Food Industry
Chocolate Production
- Microorganisms are used to enhance the flavor of chocolate through fermentation.
- There are two types of fermentation taking place during the production of chocolate from raw cacao beans: alcoholic fermentation (mediated by yeast) and acetic acid fermentation.
Market Products
- Lactobacillus, Leuconostoc, Pidococcus, Bifidobacterium, and Lactococcus are used to improve flavor, texture, and preservation of dairy and vegetable products, grain and legume fermentation products, and probiotics.
- These microorganisms ferment lactose and other sugars, and produce antimicrobial bacteria that help control unwanted microbes.
- Molecular strategies are studied to improve fermentation efficiency, better shelf life, better nutrition, and sensory product characteristics.
Explore the application of microbiology in producing important food products, managing waste, and creating bio-control agents. Learn about microbial food processing and its significance in the industry.
