Because, in summer the temperature is high and this helps milk to sour more easily than winter. But in winter it is totally opposite to it. Thus, milk turns sour more easily in summer than winter.
Because it is hotter in the summer
Because it is hotter in the summer
When milk sours it is a chemical change. It is caused by lactic acid which converts the milk and makes it become sour.
This is a chemical change.
No it is a chemical change because you change it back to normal.
The animal, I assume you are thanking about, has been a sours of milk for the people living in North West china. There mead can also be rich sours of nutrias. And lets not forget they can be as soft as a teddy bear.
yes because it is a different substance than before :)
The bacteria (Lactobacillus) needs warmth to convert milk to curd. So the setting of curd is faster in summer.
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.
the curd turn sour due to the reason that the bacteria lactobacillus which is present in curd produce waste or secondary products which turn curd in sour taste, now in summer this phenomena occur with higher speed as the bacteria get its favabourable or optimum temprature to grow..
In the winter, Chai Latte, no water, extra chai, low fat milk. In the summer, mocha frappichino with a shot of expresso.
Milk contains bacteria. Bacteria reproduces. When bacteria reproduces it lowers the pH of milk. When the pH of milk is lowered, Milk tastes sour. Bacteria reproduces faster at room temperature than it does at cold temperatures. So. Your milk will last longer in a refrigerator.
No, a chemical change. Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.
