2 days ago  For example, milk pasteurization historically was based on Mycobacterium tuberculosis and Coxiella burnetti, but with the recognition of each new pathogen, the required time temperature relationships are continuously being examined. A thermal death curve for this process is shown ://   micro-organisms Micro-organisms in retorted foods Microbial spoilage of canned foods Sterilisation process and euipment Containers for thermally treated products Cleaning of containers prior to filling Seaming of cans Death rate cure (D value) Thermal death https://safefoodcom/resources/ 2 days ago  Milk is sterile at secretion in the udder but is contaminated by bacteria even before it leaves the udder. Except in the case of mastisis, the bacteria at this point are harmless and few in number. Further infection of the milk by microorganisms can take place during milking, handling, storage, and other pre-processing :// 3. Pathogenic micro-organisms present in host cells are killed by medicines called (a) Pain killer (b) Antibodies (c) Antibiotics (d) Vaccines. Soln: The answer is (b) Antibiotics. Explanation: Pain Killers gives relief from pain. Antibodies are produced by our immune system

Microorganisms Class 8 Science Chapter 2 as per NCERT Book used in CBSE and other Schools. The lesson covers the complete explanation of class 8 Chapter 2 covered are Introduction to Micro-organisms and microbiology, different types of Micro-organisms, Useful and Harmful Micro-organisms. How to avoid spreading of Micro-organisms has been :// The lowest temperature that achieves sterilization in a given quantity of broth culture upon a minute exposure is referred to as the thermal death point. True The heat treatment of perishable liquids to destroy heat-sensitive vegetative cells and prevent infection and spoilage is called :// The destruction of pathogenic nonsporulating microbes or their toxins, usually on inanimate surfaces. Sanitization. Heat treatment of perishable fluids such as milk, fruit juices, or wine to destroy heat sensitive vegetative cells, followed by rapid chilling to inhibit growth of survivors and germination of spores. Thermal death time (TDT) Similarly, the death kinetics of the contaminating micro‐organisms can be markedly different dependent on the composition of the food product. These factors combined with the consumer demands for ‘fresher’ foods has resulted in product, process and package development and innovation progressing at a much faster rate than in the ://

Milk and dairy products are highly nutritious media, in which micro-organisms can multiply and cause spoilage. The levels and types of micro-organisms in milk and dairy products depend on the initial levels present in raw milk, the microbial quality of other raw materials, the conditions under which the products are produced and the temperature and duration of ://   The more complete, book versions of volumes 1, 2 and 3 are forthcoming -- 1.

Sterilisation can be effected by the following methods: I. Physical Methods and II. Chemical Methods. Sterilisation and Disinfection: These two terms are used to describe the killing or removal of micro-organisms. The sterilisation is an absolute term which [ ]
