Ingredients used in making Bread, yogurt, pickle and ketchup and their function

Explanation:

Bread -  It is a common staple food made by combining flour, water yeast and sometimes other ingredients. The most common way of making bread is baking. Thousands of different versions and recipes of bread are used all around the world.

Ingredients - Flour, water, salt, activated yeast. Some recipes often use eggs, herbs and oils to add extra flavor.

Flour and water are combined to form a dough. Activated yeast is added to the dough mixture to enhance fluffiness of the bread as the yeast digests some of the carbohydrates in the bread and releases carbon dioxide which makes the bread fluffy and light. This process is known as fermentation.

Yogurt -  It is made by fermenting milk with the help of  fermentation using bacteria known as yogurt cultures. These bacteria ferment the lactose present in the milk and convert it into lactic acid which gives the yogurt its characteristic flavor and texture.

Ingredients -  Cow's milk, yogurt cultures (bacteria). Some flavoring agents like herbs and spices may be added to enhance the flavor. The bacteria is extremely important for the formation of yogurt as it is responsible for the fermentation of the milk.

Pickles - Pickles are made by submerging the food material into salt brine, vinegar or oil to increase their shelf life and avoid microbial contamination.

Ingredients -  Food stuff like gherkins, cucumbers, onions, fish, mangoes, etc. the macerating liquid can be a simple salt and water solution, vinegar or oil.

These liquids ensure that there is no microbial activity in the pickles by causing ex-osmosis in the microbes present in the pickling jar which elongates the shelf life of the pickle. Some antimicrobial herbs and spices like mustard and turmeric are added to enhance the taste and act against the growth of  microbes.

Ketchup - It is a commonly used condiment where the major ingredient is tomato.

Ingredients - The most common recipe includes tomatoes, salt, sugar and vinegar along with other herbs and spices for flavor.the vinegar stops the growth of microbes in the ketchup and imparts a tangy taste to it. Some other common ingredients include cumin, garlic, cloves, ginger, mustard, etc.
