Comparative Study on the Impact of Lactic Acid Formation Over Time on Calcium Levels in Curd Made from Cow’s and Buffalo’s Milk

This study explores the process of lactic acid production in milk through natural fermentation, primarily driven by Lactobacillus species, which convert lactose into lactic acid. This acidification lowers the milk’s pH, leading to the coagulation of proteins like casein and resulting in the distinct texture and flavor of fermented dairy products such as curd and yogurt. The research emphasizes that optimal temperature conditions (30°C to 40°C) are crucial for proper curd formation. It also highlights the differences between cow and buffalo milk, noting that cow milk acidifies more slowly even at optimal temperatures, making it more effective in retaining calcium. In contrast, buffalo milk ferments more rapidly, requiring careful temperature control to prevent excessive calcium loss. Additionally, the study stresses the importance of public awareness regarding nutrient preservation. Educational initiatives through schools, health programs, and media can encourage better food preparation and storage practices. Promoting the use of fresh, local ingredients and understanding food labels can help individuals, especially vulnerable groups, make informed dietary choices. Overall, the findings underscore the need to preserve nutrients during food processing and raise awareness so that essential nutrients can be retained or supplemented as needed for individual health and well-being.A comparison of lactic acid production at different temperatures shows that the inoculum becomes more active and multiplies more rapidly at temperatures optimal for Lactobacillus, leading to faster acid development. Conversely, at lower temperatures, the growth of the bacteria slows down, resulting in a slower rate of acid formation. Interestingly, buffalo milk tends to exhibit a quicker rise in acidity than cow milk, suggesting that fermentation occurs at a faster pace. However, this rapid acid production in buffalo milk can lead to increased calcium loss, as the rising acidity dissolves calcium phosphate, which is then released into the whey and removed during curd formation
