Ethanol in the presence of oxygen and acetic acid bacteria(Acetobactor) is converted into vinegar. This is what I got from yesterday’s discussion.

Today morning, I asked my mother and grandmother about the making of appam. Grandmother said that in her days, she used to make appam by adding kallu/toddy to the dough to make it soft and sweet. My mother said that since toddy is not readily available, she add Baker’s yeast to the dough along with a pinch of sugar. She keeps this overnight. And she says that, on adding yeast, the dough rises and holes appear on it by the next day.
What is the role of sugar here? Does it increase fermentation or act as a ‘start’ for fermentation? What actually is Baker’s yeast? Does it contain live organisms? And how?

But our body is full of bacteria, both good and bad. Probiotics are often called “good” or “helpful” bacteria because they help keep your gut healthy. You can find probiotics in supplements and some foods, like yogurt.

[31/03, 5:08 pm] ayanasudheer: Fermentation is the process in which yeast acts on sugar and converts it into alcohol and carbon dioxide. It is one of the economic methods of producing new food items and also preserving food. Coconut water, coconut milk also ferment. But palm sap ferment faster (they contain high amount of sugar) Fermentation of coconut water produce more lactic acid and very less ethanol. That might be the reason why only palm sap is fermented to toddy.

[31/03, 5:11 pm] ayanasudheer: Traditional method of toddy preparation from fresh palm saps: (a) preparation for collection of saps; (b) tapping; (c) sap collection in container; (d) accumulation of sap into container; (e) filtered sap; (f) sap kept outside for natural fermentation.
