BREAD IN THIS SLIDE WE WILL EXPLAIN ABOUT BREAD

Bread  Bread is a staple food prepared by baking a dough of flour and water. It is popular around the world and is one of the world's oldest foods.  Bread is made from water, salt, flour, oil and yeast.  Gluten protein is used to make the dough sticky plastic texture which hold the bubbles of gas

Formation of bread  first, the dough is stretched after mixing it with gluten  Second, the dough is lifted for one or two hours at a temperature 27°c (in which the yeast can work)  The accumulation of carbon dioxide bubbles make the dough rises  The dough is kept in the oven at a temperature of 200°c which kills the yeast bubbles and allow the dough to become a bread.

WINE IN THIS SLIDE WE WILL EXPLAIN ABOUT WINE

WINE  It is a haram liquid formed from mainly alcohol. The natural chemical balance of grapes lets them ferment without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugars in the grapes and converts them into alcohol and carbon dioxide.  Different varieties of grapes and strains of yeasts produce different styles of wine.

 The final product may contain tens of thousands of chemical compounds in amounts varying from a few percent to a few parts per billion.  Wines made from produce besides grapes are usually named after the product from which they are produced (for example, rice wine, pomegranate wine, apple wine and elderberry wine) and are generically called fruit wine.
