The ideal pH of the finished product of yogurt should be between 4 and 4.1. This number also depends however on if you add fruits or flavoring to the yogurt. But after fermentation has been completed and the yogurt is ready to eat, the pH should be 4 to 4.6.

What is the optimum ph of yoghurt?
The pH of most yogurts is somewhere between 4.0 and 5.0. Because optimal pH tends to be the pH of the solution, the optimal pH of yogurt would be between 4.0 and 5.0 as well.
Why does pH of milk change on turning into curd?
A protein called casein, present in milk, forms a coagulum in the presence of an acid. This may result from the splitting of some of the phosphate that had been esterified to the casein and also from some proteolysis of peptide bonds in the casein molecules.

Why it is necessary to add a small amount of yogurt to convert milk into yogurt?
Yogurt converts the milk sugar to lactic acid, driving the pH down. The low pH causes the milk proteins to coagulate into a soft curd. So basically yogurt is milk transformed by harmless bacteria.

How would you show streptococcus and lactobacillus are in commercial yogurt?
The way you would prove there is Streptococcus and Lactobacillus in commercial yogurt are by:Gram Stain (both are G positive)PH levels, both release lactic acid, so the PH level should be lower than 7TasteSmelloxidase- and catalase-negativeProof,do it yourself.Eli
Why is sugar added to the milk used to make yogurt?
Sugar isn't added to the milk used to create yogurt. Often, however, sugar is added after creation to enhance the flavor. Next time you are at the supermarket, look at the ingredients list for plain, unflavored yogurt. It will contain milk and bacteria. The sugars, alternative sweeteners, fruits, and other flavorings are then added.
Is little pH bad or good?
A low pH is generally good for storing food. Canned foods have to have a pH less than 4.6 or else they need to be heated in a pressure cooker. A low pH is also good for determining when a fermentation is finished, like in yogurt. However, too low of a pH can affect the flavor, color, and texture of a food.
How the pH of milk is changed as it is turn into curd?
the PH level will be about 7 or 8 as is becomes more acidic. Actually, you are incorrect. When something becomes more acidic it is below 7. (7 being neutral). The ideal pH level for yogurt is about 4.25 on the pH scale.
How does bacteria affect the pH in milk?
Bacteria in milk causes milk to sour by changing lactose to lactic acid. This causes the pH to drop and once the pH drops low enough, the proteins in the milk will curdle.
Does yogurt calm your tongue from hot peppers?
