Adopting good housekeeping practices to reduce microbial growth . Request PDF | Intrinsic and Extrinsic Factors Affecting Microbial Growth in Food Systems | The food environment can support or reduce the ability of microorganisms to persist, establish and grow. The key to a productive staff is creating and maintaining a safe and healthy work environment. Factors-affecting-microbial-growth-in-food-pdf Plant foods have high concentrations of different types of carbohydrates and varying levels of proteins, minerals, and vitamins. Organisms having complex nutritional requirements and needing many growth factors are said to be fastidious . Organic and Inorganic Chemicals 3. Soil Moisture: Moisture is present in the form of film in soil pores. Factors affecting growth of Micro-organism in food (Intrinsic and Extrinsic) ... influence redox potential of food and finally the microbial growth. 1 0 obj Influence. Meats have abundant protein, lipids, minerals, and vitamins. <> Main factors affecting microbial growth 5. 4Bacteria grow and divide by binaryfission, a rapid and relatively simple process. 3 0 obj endobj Factor affecting bacterial growth. Growth factors are organic compounds such as amino acids , purines , pyrimidines , and vitamins that a cell must have for growth but cannot synthesize itself. <> Although bacteria do increase in size before cell division, bacterial growth refers to an increase in the number of organisms rather than an increase in their size.

Factors that. factors, which could affect microbial protein synthesis in the rumen. Effect of nutrient availability 6. Temperature requirement. Microbial growth in foods is very complex and diversified, which is governed by biochemical, environmental, and genetic factors along with their nutritional class. We discussed the nutrient requirements of microorganisms. The most important physical factors are … Some microorganism can hydrolyze triglycerides and other types of fats by microbial lipase and produces glycerol and smaller fatty acid. Nitrogen needed for amino acids and nucleotides; some can synthesize … Hurdle technology is becoming an increasingly popular preservation strategy. Extrinsic factors are those that refer to the environment surrounding the food such as temperature. •The requirements for microbial growth can be divided into two main categories: physical and nutritional.
