Question

We need warm milk to set curd. Why do you think very cold or very hot milk cannot be converted to curd?

Answer 1

Curd is made by the bacteria called lactobacillus. This bacteria develops and recreates to make curd in the warm milk. On the off chance that the milk is excessively hot or cool, the bacteria won't have the capacity to work legitimately and the curd won't be formed.

The ideal temperature for Lactobacillus acidophilus microorganisms which changes over milk into curd is 40 degrees Celsius. Beneath this temperature, the microscopic organisms do not work legitimately.

Answer 2

1.Milk is turned into curd by bacteria.
2. To make milk as curd , we need to add little pre -made curd into Luke warm milk.
3. Curd contains several micro organisms including Lactobacillus bacterium .
4. Lactobacilli bacteria promote the formation of curd from milk.
5.When little pre-made curd is added to warm milk, the Lactobacilli bacteria present in curd multiply and convert into curd.
6.Lacto bacillus bacteria convert the lactose sugar into lactic acid. This lactic acid converts milk into acid.
8.The optimum temperature for the Lacto Bacillus bacteria to convert milk into curd is 40⁰C.
9.If the milk is too hot bacteria can die and if it is too cold the bacteria cannot multiply.
