Study Notes
Biotechnological Applications in Food Industry
- Dr. Eman Owis, lecturer of Microbial Biotechnology at Mansoura University, Germany, presented on biotechnological applications in the food industry.
Food Biotechnology
- Food biotechnology is a broad field covering various aspects, including microorganisms associated with food, fermentation biotechnology, genetically modified food, enzymes in the food industry, and nanotechnology.
- Branches of biotechnology address factors influencing microbial activity, benefits of biotechnology, food safety and regulations along with different techniques associated with food biotechnology.
- The study covers importance of bacteria and yeasts in the food industry.
Fermentation Biotechnology
- The introduction to fermentation biotechnology includes the definition of fermentation, microbial agents (bacteria, yeasts, molds) involved in fermentation processes, and factors influencing microbial activity.
- The process of fermentation is discussed along with different types of fermentation, including genetically modified food, enzymes and nanotechnology.
- The roles of DNA, RNA and proteins in the process of fermentation are addressed
- An overview of molecular biology techniques and their applications in food biotechnology.
- Examination of the ethical aspects of food and agricultural biotechnology.
Outputs of the Presentation
- The lecture provided principles and bases of fermentation.
- It included principles of fermenters/bioreactors and principles of downstream processing.
Fermentation Word Cloud
- The presentation visualized various components of fermentation using a word cloud. The cloud included words like sugars, acids, carbohydrates, and preservation, indicating a wide range of applications.
Traditional Fermentation
- The origins of fermentation technology trace back to its widespread use across cultures. It has underpinned various traditional processes and laid groundwork for the development of chemistry and medicine.
- It is a process involving the conversion of organic substances into simpler compounds through digestive processes
- The process has evolved over time, reflecting the growing knowledge and use of different processes.
Historical Development of Fermentation
- The earliest archaeological evidence of fermentation dates to residues from beer (13,000 years ago near Haifa).
- Other early fermented beverages include those from fruit, rice, honey (7000-6600 BC, Jiahu) and wine (6000 BC, Georgia).
- Archaeological findings from across various ancient civilizations, including Babylon, Egypt, and pre-Hispanic Mexico, highlight wide use of fermented foods and drinks.
Fermentation Definition
- Fermentation is defined using multiple approaches from various perspectives (e.g. informal definitions for production of alcohol to more technical and scientific ones focusing on organic compound conversion).
Fermentation Process
- Different types of fermentation processes are explained. The processes include batch culture, fed-batch culture, and continuous culture.
- The presentation covered the advantages and disadvantages of each process, considering, e.g., environmental concerns (waste, emissions, pollution) and economic factors (cost, sustainability).
- Aspects like optimization of growth parameters, and fermentation media were also addressed.
Fermentation Stages
- The process involves: in-bound logistics (raw material supply and storage), upstream processing (raw material preparation), fermentation (major conversion phase), downstream processing (purification and concentration), and finally, out-bound logistics (product packaging, storage and delivery).
Industrial Fermentation Overview
- The diagram depicted the typical process steps across a typical industrial fermentation setting from obtaining raw materials, through downstream processing, product purification to final packaging and delivery
- Various stages are involved, including Upstream processing (strain selection/genetic modification, media development and Scale up) and Downstream processing (e.g. cell disruption, product separation & purification)
Applications of Fermentation
- Fermentation has applications in various sectors, including production of antibiotics, vitamins, organic acids, and toxins; industrial applications involving chemicals, agriculture, fuel production, food products and preservation (dairy products, beverages etc.) and environmental treatment (waste recycling)
Features of Fermentation-Based Industries
- Fermentation-based industries are often characterized by unique aspects: organic products, low temperature manufacturing, moderate pH, use of waste materials, and minimal emissions.
Defects of Fermentation-Based Industries
- Potential issues highlighted in the lecture include the relatively small quantities of products sometimes obtained, the need for proper strain maintenance (which may involve handling of mutations), and the challenge in separating final products from raw materials.
Conditions for Successful Fermentation
- Conditions necessary for success include the economical availability of raw materials (not already used as food), an efficient and stable biocatalyst, the precise manufacturing process, minimization of contamination and processes to secure quality and stability for product storage.
Types of Fermentation Process
- Different methods of fermentation (Batch culture, Fed-batch culture, and Continuous culture) and their processes, are described.
Culturing Methods of Microorganisms
- One of the ways of culturing microorganisms are via batch culture.
Downstream Processing
- Processes like solid-liquid separation, recovery, purification, and polishing are involved in downstream processing following completion of fermentation.
Stages of Industrial Fermentation
- The topic breaks down industrial fermentation stages into two key parts: Upstream processing (dealing with microorganism selection, media creation and process scale up) and Downstream (focused on extracting and refining the results)
General Concept Of Fermentation
- Two approaches emphasizing either the use of yeast to transform organic materials. In the modern approach, we utilize microorganisms in converting complex organic materials to simpler forms for various purposes.
- The modern concept also highlights the use of microorganisms or their products (enzymes) in transforming complex organic substrates to useful substances for humans.
