What is Food?...  Any nourishing substance that is eaten, drunk, or otherwise taken into the body to sustain life, provide energy, and promote growth.  Food helps the body: work, grow & repair itself  Any nourishing substance that is eaten, drunk, or otherwise taken into the body to sustain life, provide energy, and promote growth.  Food helps the body: work, grow & repair itself Presenter Yancy Engleton

What is Food Processing?  “The set of methods and techniques used to transform raw ingredients into food or to transform food into other forms for consumption by humans or animals.” (wikipedia.org)  It takes clean, harvested crops or butchered animal products and uses these to produce attractive, marketable and often long shelf-life food products. Presenter Tin Zar Kyaw

What is Food Processing? Cont. What Are all food processing done in factories? Presenter Tin Zar Kyaw

What are the Benefits of Food Processing?  Benefits :  Toxin removal Make many kinds of foods safe to eat by de-activating spoilage and pathogenic micro-organisms.  Preservation Enables transportation of delicate foods across long distances. Increase seasonal availability of many foods. Presenter Tin Zar Kyaw What is Food Processing? Cont.

What are the Drawbacks of Food Processing?  Drawbacks : Lower proportion of naturally-occurring vitamins, fiber and minerals. Example: canned fruits have lower content of vitamin C which is destroyed by heat in the process of canning. Chemicals used for preservation purpose can be harmful. Negative cultural consequences. Presenter Tin Zar Kyaw What is Food Processing? Cont.

 Fermentation  Milling  Controlled storage  Blanching  Freezing  Cooking Forms of Processing Presenter Gil Arreola

Forms of Processing continued  Fermentation the conversion of carbohydrates to alcohols and carbon dioxide or organic acids, using yeast and bacteria without oxygen.  Milling applies to cereals; during this process part of the original grain is removed, and depending on the extent of the milling large amounts of fat, fiber, vitamins, and minerals are lost. Presenter Gil Arreola  Controlled Storage is beneficial to fruits and vegetables. Controlled atmosphere storage is done to increase the storage life of foods, under an atmosphere different than air. Without a controlled storage may fruits would not be available through out the year. Fermentation Controlled Storage

Forms of Processing continued  Blanching is the heating of fruits and vegetables using steam or water. Heating is not meant to cook the food, but to inactivate substances that would affect the nutrient content, color, flavor and texture during processing and storage. Blanching is an important step before canning, drying or freezing of food.  Freezing is done to conserve food to eat at a later date. If the temperature is controlled at -18°C, longer storage times can be achieved. Presenter Gil Arreola Blanching  Cooking is important in food processing because nutrients are converted into a form that can be used by our bodies. Cooking is also necessary to ensure that food is free from harmful levels of micro-organisms. Freezing

Cooking Methods  Steaming  Braising  Barbecuing  Grilling  Stir-frying  Baking  Roasting  Broiling  Frying  Boiling  Microwaving Presenter Eddie Herrera

Baking: to cook in an oven or an oven-type appliance Roasting: Uses dry heat in an oven, indirect heat Broiling: direct intense heat from above Presenter Eddie Herrera

 There are various ways to frying food  Shallow frying: Cooking food in a small portion of preheated oil inside of a shallow pan or griddle. (hamburgers, hashbrowns)  Deep frying: Cooking food in a deep portion of preheated oil inside a deep pan or deep fryer. (doughnuts, fries, chicken) Presenter Eddie Herrera

Quiz: 1.What flavor does alkalinity give food? 2.Give one Benefit of Food Processing? 3.What is the key difference between Barbeque and Grilling? 4.Give two key components of a well balance meal? 5.Name at least two forms of food processing?
