Fermented food items like fermented soybeans and fermented bamboo shoots are consumed as traditional food in some parts of India. With the help of your parents and teachers, list some traditional food items from your area that utilise the process of fermentation. Investigate the ingredients used in the preparation of these fermented food items; the method of preparing them; the microorganism responsible for the fermentation of the food, and the cultural and nutritional importance of the fermented food.
Traditional fermented foods from different regions of India include several popular items that are prepared using the process of fermentation.
Idli and Dosa (South India) are made from fermented rice and lentil batter using Lactobacillus bacteria, which makes the batter soft and nutritious.
Curd/Yogurt (pan-India) is made by fermenting milk with Lactobacillus bacteria. It is rich in probiotics and calcium.
Dhokla (Gujarat) is made from fermented gram flour batter using bacteria. Bhatura (North India) is made from fermented flour dough using yeast.
Pickles (various regions) are preserved using salt, oil, and natural fermentation by lactic acid bacteria.
Fermentation enhances nutritional value by increasing vitamin content, making nutrients more bioavailable, and adding beneficial probiotics that improve gut health.
These foods hold cultural significance in festivals, daily meals, and regional cuisine identity.
Explanation
Activity 2.8 and 2.9 in the chapter explain the role of yeast and Lactobacillus bacteria in fermentation. Yeast makes bread soft and fluffy by producing carbon dioxide. Lactobacillus ferments milk to form curd by producing lactic acid. The chapter mentions that in addition to yeast, bacteria like Lactobacillus help in fermentation of batter for making idli and dosa, and dough for making bhatura.
