It is an endothermic reaction. It absorbs heat while freezing.
Setting of curd is a chemical change b'coz when lactobacillus bacteria comes in contact of milk they convert the milk to curd due to some biochemical reasons.
Yes, curd (or yogurt) is more acidic than milk because it is produced by fermentation, which involves the conversion of lactose (milk sugar) into lactic acid by bacteria. This increase in acidity results in the characteristic tangy flavor of curd that is not present in milk.
As milk turns into curd, lactic acid bacteria ferment lactose into lactic acid, causing the pH to decrease. The pH of curd is usually around 4.6 to 4.8 due to the build-up of lactic acid during fermentation.
the protein in the milk is denatured, therefore it cannot return to its original structure. the tertiary and quaternary structure of the original protein changes, bonds are broken and others reformed, these cannot be changed. the process is similar to that of cooking an egg, once it has been cooked it cannot change back to its raw state.
The pH of milk decreases when it turns into curd because the bacteria used in the fermentation process produce lactic acid as they consume the lactose in the milk. This accumulation of lactic acid lowers the pH of the milk, which helps in the coagulation of milk proteins to form curd.
This is a chemical change.
yes!
no change
The process of milk turning into curd is a chemical change because it involves the fermentation of lactose by bacteria present in the curd culture. This fermentation process causes a change in the chemical composition of the milk, leading to the formation of curd through the breakdown of lactose into lactic acid.
To change into curd; to coagulate; as, rennet causes milk to curdle., To thicken; to congeal., To change into curd; to cause to coagulate., To congeal or thicken.
bacteria turns milk into curd.
Curd &milk are posine or not
Setting of curd is a chemical change b'coz when lactobacillus bacteria comes in contact of milk they convert the milk to curd due to some biochemical reasons.
Due to process fermentation of microorganism the milk turns into curd.
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 formation of curd is a natural change because it involves a chemical reaction between lactic acid bacteria and milk, resulting in the coagulation of the milk proteins. This process occurs spontaneously without the need for human intervention.
Lactobacillus is a type of beneficial bacteria that plays a key role in the fermentation process that turns milk into curd. When milk is inoculated with Lactobacillus, it ferments the lactose (milk sugar) and converts it into lactic acid. This acid causes the proteins in milk, particularly casein, to coagulate and form the thick, creamy texture of curd. The fermentation process also enhances the nutritional value of the milk by introducing probiotics, which promote gut health.
