Which organisms turn milk into curd?
bacteria turns milk into curd.
Why curd is added while making idle and bhatura?
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.
How bacteria help in making curd?
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.
Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?
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.
Formation of curd from milk is which reaction?
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.
Why do you think milk is warmed a little before adding curd?
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.
Explain why curd forms when milk sours?
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.
Is curd a pure substances?
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.
Why does curd become sour if it is not transferred to cool place after it is set?
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.
Why curd is added while making idlis and bhaturas?
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.
Why do you think Curd sets faster in summer than in winter?
The bacteria (Lactobacillus) needs warmth to convert milk to curd. So the setting of curd is faster in summer.
What do you produce when you use bacteria that uses lactic acid?
curd
