Describe Three Beneficial Uses of Microbes in Food.

Bacteria are not only present outside the human body but they also live inside the body too. Growing legumes Leguminous plants such as soybeans peas clover alfalfa and beans form intimate associations with nitrogen-fixing bacteria like Rhizobium.

Among those beneficial microorganisms that are found in growing plants that are healthy for human consumption as well as in producing other useful products to man are the following.

. Plantarum is known for its ability to produce hydrogen peroxide. As the name connotes lactic acid bacteria produce lactic acid usually from sugars or other carbohydrates. Lysine is produced by Brevibacterium flavum whilst glutamic acid is produced by Corynebacterium glutamicum.

The fermentation process leading to the production of alcoholic beverages or acid based dairy products takes place when microorganisms get energy from food cells without having to take oxygen. Fungi like yeast or bacteria like Lactobacilli Are essential in the food industry Lasztity 1996. Microbes are useful for us in many ways in various industries.

Yeasts are the most widely used micro-organisms in the food industry due to. It is used for preservation of milk. From low grade ores which otherwise cant be economical.

The lactic acid bacteria and fungi such as Aspergillus produce the distinctive taste of soy sauce. Lactic acid bacteria are used to make yogurt cheese sour cream buttermilk and other fermented milk products. Their use in the food industry is limited eg.

Microbes play an important role in our body shape by helping us digest and ferment foods as well as by producing chemicals that shape our metabolic rates. Microbes keep us slim. Minimizing contamination from raw or unprocessed food people equipment and the environment.

THE MICRO-ORGANISMS that act on foods may be divided into two general groups. Bacteria are used to recover metals like nickel lead zinc copper etc. And of course microbes are essential to making many foods we enjoy such as bread cheese and wine.

Microorganisms are used to change one substance to another which is used as food such as milk to yoghurt and cheese sugar. And sudden cooling at4-5C to kill the non-spore forming bacteria. It is used as a food additive to enhance its nutritional value.

The beneficial uses of bacteria include the production of traditional foods such as yoghurt cheese and vinegar. Studies have also found that this strain helps effectively support immune function in healthy adults. Use of micro-organisms for making many products including such every- day foods as bread and cheese.

Removing or destroying them by trimming washing heating pickling. Vinegars are produced by bacterial acetic acid fermentation. Microorganisms and its uses 1.

Adding chemicals like acid or alcohol or by encouraging competition to form organisms. And biological control of. Supports the whole digestive process.

The micro-organisms occurring on andor in foods are from a practical point of view divided into three groups. Bacteria are the key players here. The table below lists a few with their uses.

Production of Foods - Microbes are a key component in both home and industrial food preparation. Bacteria help in fermentation which helps in making different forms of dairy products from milk like curd buttermilk butter cheese. Uses of Microorganisms Food Industry and Beverages.

There are many useful application of microbes in the food industry. It is the heating of milk at 628 C for 30 min of 716C for 15 sec. - prevent food from spoiling - biofilms - biofuels such as ethanol - recycling vital elements - production of foods medicines - pest control - manufacturing products - bioremediation - water sewage treatment.

Molds are generally concerned in the spoilage of foods. The body uses hydrogen peroxide as a line of defense against bacteria in food as well as other microorganisms. The food processor reduces potential problems from microorganisms in several ways.

Minimizing microbial growth by cleaning and. Human and animal digestion. Molds yeast and bacteria.

Bacterially Produced Amino-acids Used as Food Additives. Biotechnology and genetic engineering producing substances such as drugs and vitamins. Millions of metric tonnes of amino acids are produced commercially each year.

Eisen explains It seems that disturbances in our microbial community may be one of the factors leading to an increase in obesity. Streptococcus is the most common genus of bacteria that are used in the commercial production of this product. For example each human body hosts 10 microorganisms for every human cell and these microbes contribute to digestion produce vitamin K promote development of the immune system and detoxify harmful chemicals.

Vinegar is made not by lactic acid but by the acetic acid bacteria from wine apple cider or dilute ethanol. Minimizing contamination from equipment people the environment and from unprocessed food. They influence the quality availability and quantity of food.

Production of dairy products. The role of microorganisms in food preparation and beverage manufacturing is known for ages. Microorganisms are used in the production of fermented foods and beverages.

1 Those bringing about spoilage and deterioration and 2. Removing or destroying them by trimming washing heating pickling by adding chemicals or by encouraging competition.
