The bacteria is called Lactobacillus and Bifidus, just two of the many types of lactic acid microorganisms, convert lactose sugars in milk into lactic acid.
Curd is added while making idlis to enhance fermentation, which is crucial for achieving the light and fluffy texture characteristic of idlis. The lactic acid bacteria in curd promote the fermentation process, helping to leaven the batter. Additionally, curd contributes to the flavor and nutritional value of the idlis, making them softer and more palatable.
bacteria turns milk into curd.
Yogurt (curd) is added to idli and bhatura batter as a fermenting agent. The bacteria in the curd help in the fermentation process, which creates a light and fluffy texture in idlis and bhaturas. This also helps in making the final dish more digestible.
Bacteria, such as Lactobacillus, play a crucial role in making curd by fermenting the milk sugars into lactic acid, which gives curd its tangy taste and thick texture. These bacteria also help in breaking down proteins in milk, resulting in the coagulation and solidification of curd. Additionally, these beneficial bacteria help inhibit the growth of harmful bacteria, contributing to the preservation and safety of curd.
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
Warming the milk before adding curd helps promote better and faster fermentation. The slight increase in temperature creates an ideal environment for the beneficial bacteria in the curd to multiply and convert the milk into yogurt.
Formation of curd in milk is called 'Fermentation'.Curd is formed when milk is pasteurised and fermented by a combination of lactic acid bacteria and a protease.
The curd is the fat in the milk that sticks together. ------------------------------------------------------------------- I think it is the proteins rather than the fat that are responsible for the formation of curd - after all you can get fat free curd cheese.
Curd is not considered a pure substance; it is a mixture. It contains water, proteins, fats, lactose, and various microorganisms, such as bacteria, which contribute to its texture and flavor. The composition of curd can vary depending on factors like the type of milk used and the fermentation process, making it heterogeneous.
Curd does not typically contain yeast; it is primarily made through the fermentation of milk by specific bacteria, mainly lactic acid bacteria. These bacteria convert lactose into lactic acid, which thickens the milk and gives curd its tangy flavor. While yeast can be present in some fermented dairy products, it is not a standard component of traditional curd.
Curd contains live bacteria that continue to ferment the milk sugars even after it has set. If the curd is not transferred to a cool place, the bacteria will continue to multiply and produce more lactic acid, causing the curd to become increasingly sour.
Curd is added while making idli and bhatura dough as curd contains Lactobacillus bacteria that undergoes anaerobic respiration and in this process it acts on sugar of the flour and releases carbon dioxide gas, this gas make the dough rise and when baked or fried gas escapes leaving the idli or bhatura soft and spongy.
