pH Of Yogurt | pH Of Greek Yogurt
Yogurt, highly nutritious fermented milk product, is made by curdling cow’s milk with specific bacterial strains like Lactobacillus bulgaricus and Streptococcus thermophilus. These strains are added with milk, the mixture of bacteria and milk is then incubated for the conversion of lactose into lactic acid. This acid is responsible for low pH of yogurt. Due to the acidic mixture the casein protein in milk coagulates and precipitate out thus thickening the milk into yogurt like texture. Many people have confusion that yogurt is alkaline or acidic in nature. The answer is acidic . Generally, the pH of yogurt is in the range of 4-4.6, averagely 4.4.
Lactic acid present at this pH is ideal for yogurt. Besides preventing the microbial growth due to low pH, lactic acid also aids in thickening and it also provides a characteristic tartness to yogurt.The characteristic taste and flavour of yogurt is mainly due to production of 4 major acids- lactic acid, acetaldehyde, acetic acid and diacetyl acid. Theses 4 acids leads to development of strong immune system that’s why yogurt is considered as highly nutritious. In the production of yogurt, pH is the critical control point. pH of yogurt decides its quality and consistency. Any deviation from a standard pH can decrease shelf life of yogurt or can affects its taste. Thus if you want to prepare a delicious and healthy yogurt your main consideration should be pH.
