Course Outline Institut Pertanian Bogor - ACICIS’ Agriculture Semester Program Unit name Food Fermentation Technology (ITP321) Department/ Faculty Food Science and Technology Faculty of Agriculture Technology Course credit (SKS) 2 (2-0) Offered in Even semester (February-July) Pre-requisite Food Microbiology Course Coordinator Lilis Nuraida Language Indonesian English Both Course description This course discusses the use of microorganisms in fermentation technology and biotechnology which cover principles and history of fermentation, microbial metabolisms and regulation, strain improvement, microbial isolation and screening, culture preservation, fermentation techniques and conditions and their application in the production of enzymes, amino acids, alcohol, acetic acid, lactic acid, biomass and mixed fermentation commonly implemented in food industries. This course is designed to enable students develop a food fermentation process using microorga- nisms and local based substrate. Food Fermentation technology is a mandatory course for students enrolling in Food Technology Study Program at the Department of Food Science and Technology, Bogor Agricultural Technology. As a part of food processing technology, fermentation technology has evolved from spontaneous to controlled processes employing improved strains commonly obtained from the benefit of biotechnology development in large industrial scales to produce food, ingredients and additives important for food. Food fermentation technology covers (1) the principles of fermentation technology, including fermentation history, microbial isolation and screening techniques, microbial metabolisms and their regulations, strain improvement, culture preservation, bio-reactor for industrial scale production and (2) application and use of the principles in various fermentation process, i.e. in the production of amino acids, enzymes, alcoholic food and beverages, acetic acids, lactic acid fermented foods, lactic acid bacteria for probiotics, biomass, additives and other ingredients. The knowledge is important for students to understand the mechanisms behind food fermentation processes, especially with regard to the processes that may be controlled after understanding the microbial behaviour as dictated by their metabo-lisms and regulation as well as chemical changes in raw material that occurs during fermentation that may be beneficial pertaining its shelf life, digestibility, improved taste and flavour, reduced toxicity and health functions. Learning outcomes Upon successful completion of this course students are expected to be able to design a food fermentation process starting from isolation, screening and preservation of microorganisms, selecting the fermentation conditions, and preparing the necessary step for isolation and harvesting of the products.
