The terms “curd” and “yoghurt” are often used interchangeably, but they have distinct differences in terms of their production process, texture, and nutritional content. While both are popular dairy products, they cater to different tastes and dietary needs. In this article, we will delve into the world of curd and yoghurt, exploring their differences, benefits, and uses.
Introduction to Curd and Yoghurt
Curd and yoghurt are both fermented dairy products, but they are made using different methods and have unique characteristics. Curd is a traditional Indian dairy product made by curdling milk with an acidic substance like lemon juice or vinegar. The curdling process involves the coagulation of casein, a milk protein, which results in a soft, white, and creamy texture. On the other hand, yoghurt is a fermented milk product that originated in the Balkans and is made by adding bacterial cultures to milk. The bacterial fermentation process thickens the milk and gives yoghurt its characteristic tangy flavor and smooth texture.
Production Process
The production process of curd and yoghurt is a crucial aspect that differentiates them. Curd is made by adding an acidic substance to milk, which causes the casein to coagulate and separate from the whey. The resulting curd is then drained and pressed to remove excess liquid, leaving behind a thick and creamy texture. In contrast, yoghurt is made by adding bacterial cultures like Lactobacillus bulgaricus and Streptococcus thermophilus to milk. The bacteria feed on the lactose in the milk, producing lactic acid and causing the milk to thicken and curdle. The yoghurt is then incubated at a warm temperature to allow the bacteria to grow and develop the characteristic flavor and texture.
Bacterial Cultures
The type of bacterial cultures used in yoghurt production is a key factor that differentiates it from curd. Yoghurt contains live and active cultures, which provide various health benefits, including improved digestion and immune system function. Curd, on the other hand, does not contain live cultures, as the acidic substance used to curdle the milk kills the bacteria. However, some types of curd, like probiotic curd, are made by adding bacterial cultures to the milk before curdling, which provides similar health benefits to yoghurt.
Nutritional Content
The nutritional content of curd and yoghurt is another aspect that distinguishes them. Both are excellent sources of protein, calcium, and vitamins, but they have different levels of these nutrients. Curd is higher in protein and calcium compared to yoghurt, making it an excellent option for those looking to increase their protein intake. Yoghurt, on the other hand, is lower in calories and fat compared to curd, making it a popular choice for those watching their weight. Additionally, yoghurt contains more probiotics and live cultures, which provide additional health benefits.

What is the primary difference between curd and yoghurt?
The primary difference between curd and yoghurt lies in their preparation methods and the type of bacteria used in the fermentation process. Curd is prepared by adding a spoonful of curd to boiled and cooled milk, which contains Lactobacillus acidophilus bacteria. This process helps to convert the milk sugar (lactose) into lactic acid, resulting in the curd’s characteristic texture and taste. On the other hand, yoghurt is made by adding a yoghurt culture that contains Lactobacillus bulgaricus and Streptococcus thermophilus bacteria to the milk.
The distinct bacteria used in curd and yoghurt production contribute to their unique taste, texture, and nutritional profiles. For instance, the Lactobacillus acidophilus bacteria in curd are more effective in breaking down lactose, making it easier to digest for people with lactose intolerance. In contrast, the bacteria present in yoghurt, such as Lactobacillus bulgaricus, are known for their ability to enhance the immune system and improve gut health. Understanding the difference in the bacteria used in curd and yoghurt can help consumers make informed choices about which one to include in their diet.
How do the textures of curd and yoghurt differ?
The textures of curd and yoghurt differ due to the variation in the fermentation process and the type of milk used.
