Difference Between Curd and Yogurt

Have you ever wondered if curds and yogurt are the same? Many people use these terms interchangeably, but they are two different dairy products. If you searched for “curd vs. yogurt,” “the difference between dashi and yogurt,” or “is dashi and yogurt the same?”, you are not alone – it’s a common confusion!

Is yogurt the same as curd? no. Yogurt and curd are different. Dahi (curd) is a staple food for Indian families, making fresh cream with natural fermentation processes every day, while yogurt is a commercially produced dairy product with specific bacterial cultures. Both are formed from fermented milk, but the process, bacteria and final texture vary greatly.

So, what is the separation between curd and yogurt? Let’s break it down with definitions, key differences and interesting trivia!

What is curd?

Curd Dashi

Curd, also known as Dahi, is a natural fermented dairy product formed by the action of lactic acid bacteria. It is made by adding a curd starter or natural acidic agent such as lemon juice or tamarind to warm the milk. This triggers a lactic acid fermentation process in which bacteria convert lactose (milk) into lactic acid, causing the milk to clot and thicken into curd.

The scientific process of curd formation:

Bacteria involved – The main bacteria responsible for the formation of curd come from the environment or curd starter. These include Lactobacillus and Lactobacillus Delbrueckii.

Lactic acid production – These bacteria break down lactose into lactic acid (C3H6O3) through glycolysis.

Milk coagulation – Increased acidity reduces pH (from ~6.7 to ~4.6), making casein proteins unstable, which will make them unite and form a thick curd.

Key facts about curd (Dahi):

  • It is homemade and widely consumed in Indian households.
  • The fermentation process is natural and uncontrollable, resulting in changes in texture and taste.
  • The microbial composition depends on the temperature, milk quality and the appetizing culture used.
  • It is used in dishes such as Raita, Lassi, Buttermilk, Kadhi and Dahi Vada.
  • The acidity and microbial content may vary, making it slightly sweet or rich in taste.

What is yogurt?

Yogurt dashi

Yogurt is a commercially produced fermented dairy product made using specific bacterial strains Lactobacillus Bulgarian and Streptococcus thermophilus. Unlike curds, the fermentation process of yogurt occurs in a controlled environment to maintain uniform taste, texture and probiotic benefits.

The scientific process of yogurt formation:

Bacteria involved – Yogurt fermentation using defined start culture Lactobacillus Bulgarian and Streptococcus thermophilusthis is symbiotic.

Lactate Fermentation – These bacteria convert lactose to lactic acid, reducing the pH to ~4.5, resulting in a thicker, creamier consistency.

Protein denaturing–A decrease in pH results in casein micelles (milk proteins) aggregation, forming a uniform gel-like structure, which is characteristic of yogurt.

Key facts about yogurt:

  • Use scientifically controlled bacterial cultures to ensure consistency.
  • It comes in various types including regular yogurt, Greek yogurt and flavored yogurt.
  • Bacterial strains remain active and active, making them a probiotic-rich food.
  • It has a smooth, even texture and can be used in smoothies, desserts, salad seasonings and breakfast bowls.
  • Standardized production processes ensure that they have consistent taste and texture between batches.

in conclusion

Although curd (Dahi) and yogurt may look similar, there are obvious differences in their preparation, fermentation process, and usage. Dahi is a naturally fermented dairy product that is usually prepared in Indian homes, while yogurt is made with specific bacterial cultures under controlled conditions to ensure consistency.

Curd is a staple in traditional Indian cuisine, while yogurt gains worldwide popularity, with different varieties such as Greek yogurt, flavored yogurt and probiotic-rich options. Understanding these differences can help clarify why curds and yogurt are different

Now that you know the difference, the next time someone asks “curd is the same as yogurt?” you will have the perfect answer!
