Why are food preservatives not required to inhibit the growth of bacteria in yoghurt?
Food preservatives are not required to inhibit the growth of bacteria in yogurt because the fermentation process itself relies on specific beneficial bacteria, such as Lactobacillus and Streptococcus, which create an acidic environment. This acidity inhibits the growth of pathogenic bacteria while allowing the desired cultures to thrive. Additionally, the low pH and high competition from these beneficial bacteria naturally help preserve the yogurt, making additional preservatives unnecessary.

Explain the formation of yogurt with the help of microorganisms?
Milk + Bacteria -> Yoghurt by elvis
Why do soem bacteria produce lactic acid?
Good question! In yoghurt production, the bacteria Lactobacillus is added to milk. The Lactobacillus is cultured at 46 degrees celcius, releasing lactic acid into the milk and converting the milk into yoghurt.
What household item contains good bacteria?
Yoghurt contains active bacteria cultures which are of no harm to humans these are normally from the yoghurt making process. However pro biotic yoghurts have a wider range of bacterial cultures which may aid the digestive system.
Why is yogurt incubated?
The production of yoghurt requires certain bacteria: these bacteria live and reproduce better at warm conditions. It's as simple as that!
What is the purpose of bacteria in yogurt?
Not all bacteria is unhealthy, even though it may seem all is bad for you. Yoghurt is considered a healthy food, and its the good bacteria that makes it healthy.
Why is yoghurt acidic?
A type of bacteria called "Lactic acid bacteria" ferment milk sugars, lactose to produce lactic acid. Its PH is around 4-5 and therefore it is acidic. Depending on the age and bacteria activity of the yoghurt, the inoculated milk can acidify the sugars enough to coagulate the proteins , resulting into a custard-like curd.
Yogurt is made by changing?
Yoghurt is actually made of mik but bacteria is introduced to it to give it a yoghurty consistency
Is yogurt made from condensed milk?
Yoghurt is made from pasteurised milk to get rid of any harmful bacteria
