Food Preservation and Methods physical methods simple notes

Physical methods Food Preservation and Methods Food preservation is essential for extending the shelf life of food products, maintaining their nutritional value, and ensuring food safety. Various methods and principles are applied in food preservation to prevent microbial degradation, self-decomposition, and damage from insects, animals, or mechanical causes. Here, we discuss several methods and the principles behind them. Principles of Food Preservation Preventing or Delaying Microbial Degradation Asepsis : Keeping microorganisms out of food through sterile conditions. Filtration : Removing microorganisms using filters. Growth Inhibition : Using low temperatures, drying, anaerobic conditions, or chemicals to stop microbial growth or activity. Microbial Destruction : Killing microorganisms through heat or radiation. Preventing or Delaying Self-Decomposition Enzyme Inactivation : Destroying or inactivating food enzymes, e.g., through blanching. Use of Antioxidants : Preventing or delayi...

Microbiology Taxonomy short notes easy to understand

  MICROBIAL TAXONOMY   The biological science field of taxonomy includes the three closely linked fields of identification, naming, and classification. A systematic approach for naming, categorizing, and identifying organisms is provided by taxonomy, which may be applied to all living things. This standardization makes it possible for biologists all around the globe to refer to any creature they investigate in their respective domains using the same vocabulary. Scientists can concentrate on more important scientific problems and phenomena since taxonomy is a global language that clears up name misunderstanding. In order to detect infections accurately and promptly, diagnostic microbiology relies heavily on the taxonomy, naming, and identification of bacteria. Father of Taxonomy Carl Linnaeus (23 May 1707 – 10 January 1778), also known as Carl von LinnĂ© after his ennoblement in 1761, was a renowned Swedish biologist and physician. He is celebrated for formalizing the binomial n...

Melanin production of humans

  MELANIN PRODUCTION OF HUMANS Melanin is a complex polymer that originates from the amino acid tyrosine. Melanin is present in human and animal skin to varying degrees, and is responsible for your unique eye, hair and skin color.Melanin is a substance in your body that produces hair, eye and skin pigmentation. The more melanin you produce, the darker your eyes, hair and skin will be. The amount of melanin in your body depends on a few different factors, including genetics and how much sun exposure your ancestral population had. Melanin production begins in large cells called melanocytes, which can be found all over the body. Melanocytes are responsible for producing organelles called melanosomes. Found the Melanin in Human Parts: ·  Hair . ·  Pupils or irises of the eyes . ·  The medulla and zona reticularis of the adrenal gland . ·  Skin where it provides skin color . ·  Stria vascularis of the inner ear . ·  Areas of the brain, the substantia nigra ...
