Why Curd Turns Sour Faster in Summer than in Winter?
Curd is a dairy product that is made by adding bacteria to milk. The bacteria ferment lactose in milk, which produces lactic acid. As a result, the milk thickens and turns into curd. However, curd is a perishable product and needs to be stored at the right temperature to prevent it from turning sour. In this article, we will explain why curd turns sour faster in summer than in winter.
1. Temperature
Temperature is the most significant factor that affects the fermentation process of curd. In summer, the temperature is warm, and bacteria grow and multiply faster, leading to faster fermentation. On the other hand, in winter, the temperature is low, and bacteria grow and multiply slowly. Therefore, curd takes more time to ferment, and the chances of it turning sour are relatively less.
2. Humidity
Humidity is another factor that affects the fermentation process of curd. In summer, the humidity is high, which creates a favorable environment for bacteria to grow and multiply. The high humidity also leads to the formation of moisture on the surface of the curd, which promotes the growth of bacteria. In contrast, in winter, the humidity is low, which does not create a favorable environment for bacteria to grow and multiply. Therefore, curd takes more time to ferment, and the chances of it turning sour are relatively less.
3. Handling and Storage
The way curd is handled and stored also affects its fermentation process. In summer, curd should be stored in a cool and dry place to prevent it from turning sour too quickly. It should also be covered properly to prevent contamination from bacteria and other microorganisms. In contrast, in winter, curd can be stored at room temperature as the low temperature slows down the fermentation process. However, proper handling and storage are still essential to prevent contamination and ensure freshness.
Conclusion
In conclusion, curd turns sour faster in summer than in winter due to the higher temperature and humidity. The warm and humid environment creates a favorable environment for bacteria to grow and multiply, leading to faster fermentation. Therefore, it is essential to store curd properly and handle it carefully to ensure its freshness and prevent it from turning sour too quickly.
