Lactic acid fermentation of milk. Species of lactic acid bacteria LAB represent as potential microorganisms and have been widely applied in food fermentation worldwide. Milk fermentation process has been relied on the activity of LAB where transformation of milk to good quality of fermented milk products made possible. The presence of LAB in milk fermentation can be either as spontaneous or inoculated starter cultures.

Properties of Lactic Acid Bacteria Milk fermentation process has been relied on the activity of LAB which play a crucial role in converting milk as raw material to fermented milk products. The lactic acid fermentations are generally inexpensive and often little or no heat is required in their preparation making them fuel efficient as well. Foods fermented with lactic acid play an important role in feeding the worlds population on every continent.
This review was conducted to find out the main function of lactic acid bacteria in milk fermentation and preservation. Lactic acid bacteria LAB are a group of Gram-positive non-spore forming. Lactic Acid Fermentation of Pasteurized And Powdered Milk And Optimizing The Factors Affecting The Fermentation Process INTRODUCTION 11 IMPORTANCE OF THIS STUDY Yogurt also spelled yoghurt is a semisolid fermented milk product that originated centuries ago and has evolved from many traditional Eastern European products.
The presence of lactic acid or lactate in milk is due to the fermentation of lactose caused mainly by lactic bacteria. Generally speaking just-milked milk does not contain lactic acid but this increases after a while and its concentration is closely correlated to the total bacterial charge. In the case of milk when good healthy bacteria such as Lactobacillus delbrueckii bulgaricus and Streptococcus salivarius thermophilus are added and a particular temperature is reached they start to nibble at the tasty molecules of lactose which is a sugar transforming them into pyruvic acid.
In the absence of oxygen the latter eventually turns into a lactic acid. Now seeing as there are also many. Species of lactic acid bacteria LAB represent as potential microorganisms and have been widely applied in food fermentation worldwide.
Milk fermentation process has been relied on the activity of LAB where transformation of milk to good quality of fermented milk products made possible. When fermenting milk lactic bacteria convert part of α- and β-lactoses into d - and l - lactic acids causing a pH decrease responsible for casein coagulation. Lactic acid monitoring during fermentation is essential for the control of dairy gel textural and organoleptic properties and is a way to evaluate strain efficiency.
Lactic acid fermentation commonly referred to as lacto-fermentation is one of the most common and easiest methods of home preservation. Lactic acid fermentation was a method used to preserve dairy products vegetables and meat for extended periods of time before the advent of refrigeration and modern canning practices and today is also utilized in industrial fermentation.

Kefir are called fermented or cultured milks. Fermented milk also known as cultured milk is a type of dairy food which is made by adding lactic acid bacteria mold or yeast to milk. The specific chemical reaction and product that results from fermentation depends upon the type of bacteria used and the process by which it.

L-Lactic acid in milk Lactic acid is produced by the fermentation of lactose mainly through microbial activity. Its concentration depends on the total bacterial count and can be a useful indicator of the good state of preservation.
