Food Processing Standard: 19.0 Describe Food Safety and Processing Practices Measurement Criteria:19.2 Describe food-processing practices
2
What is food processing?
Techniques used to slow deterioration and allow people to enjoy foods in a variety of forms around the year and around the globe. Food processing turns raw agricultural product into attractive and consumable food.
3
What is the importance of food processing to human health?
increases variety increases convenience improves quality of food
4
What are five food-processing methods?
Fermentation - Production of CO2 through anaerobic respiration, also produces lactic acid alcohol in the process. Canning - Sterilize food by getting it to a temperature of F, then putting it into airtight containers Dehydration - Lowers moisture content to inhibit growth of microorganisms Irradiation - Uses gamma rays to kill insects, bacteria, fungi, etc. in food products. Blanching - Briefly scald food to inactivate enzymes that cause undesirable changes.
5
Method- Fermentation Advantages Disadvantages Improves taste
Adds value to crops, such as cucumber Disadvantages Rather lengthy process in comparison to other food processing techniques.
6
Method- Canning Advantages Disadvantages Increases shelf life
2 years is considered normal shelf life Disadvantages Weight of product Requires specially treated metal cans or appropriate glass jars.
7
Method-Dehydration Advantages Disadvantages
Increases shelf life up to 2 years Lighter weight Lower volume Disadvantages Changes taste and texture of food Typically requires preparation to reconstitute food.
8
Method-Irradiation Advantage Disadvantages
Gamma rays pass through without heating or changing it, therefore no heat sensitive nutrients are lost in the process Disadvantages High cost Perception of irradiation
9
Method-Blanching Advantage Disadvantage Improves taste
Increases availability of out of season foods Disadvantage Storage limits Fruits & veggies 1 year Meat 3-6 months Freezing temperatures required for storage
