How is bacteria used in food production?
How is bacteria used in food production?
Nature uses microorganisms to carry out fermentation processes, and for thousands of years mankind has used yeasts, moulds and bacteria to make food products such as bread, beer, wine, vinegar, yoghurt and cheese, as well as fermented fish, meat and vegetables.
How does bacteria affect food quality?
Microbial spoilage is caused by microorganisms like fungi (moulds, yeasts) and bacteria. They spoil food by growing in it and producing substances that change the colour, texture and odour of the food. Eventually the food will be unfit for human consumption.
Where is bacteria used in food?
Bacteria are not only used for fermentaion in the dairy industry, but for use in other such food production as in the processing of coffee and cocoa, the manufacturing of food additives, and other such processes such as the making of xanthan gum and vinegar. Bacteria, and most viruses do not tolerate acids.
Why is bacteria in food important?
Microbiology is important to food safety, production, processing, preservation, and storage. Microbes such as bacteria, molds, and yeasts are employed for the foods production and food ingredients such as production of wine, beer, bakery, and dairy products.
What type of bacteria causes food spoilage?
The predominant bacteria associated with spoilage are Brochothrix thermosphacta, Carnobacterium spp., Lactobacillus spp., Lactococcus spp., Leuconostoc spp., Pediococcus spp., Stretococcus spp., Kurthia zopfii, and Weisella spp.
What is the name of the bacteria on food?
Some Common Foodborne Germs Salmonella. Clostridium perfringens. Campylobacter. Staphylococcus aureus (Staph)
Which food has the most bacteria?
Raw foods of animal origin are the most likely to be contaminated, specifically raw or undercooked meat and poultry, raw or lightly cooked eggs, unpasteurized (raw) milk, and raw shellfish. Fruits and vegetables also may get contaminated.
What type of bacteria causes most food poisoning?
In most cases of food poisoning, the food is contaminated by bacteria, such as salmonella or Escherichia coli (E. coli), or a virus, such as the norovirus.
What are three foods that have been made using bacteria?
Bacteria, often Lactobacillus, along with yeasts and molds, have been used for thousands of years to make fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, beer, and yogurt (some of which are shown in Figure below.)
