Methods of Preservation
The removing water from foods to create a lighter, smaller, and preserved product.
What is drying/dehydration.
The storing of food at any temperature between 32*F and 0*F.
What is frozen storage.
The __________ is an international symbol and must be stamped on any irradiated products.
What is radura.
Salt solution used to preserve food through fermentation.
The reason food preservation is important.
What is- allows food to have an extended shelf life so consumers are able to store food easily and conveniently.
The addition of any substance used to maintain or improve the quality of food.
What is food additives.
The main benefit of frozen storage over cool storage is?
What is- frozen storage maintains food quality factors like size, shape, texture, color, and flavor.
GMO stands for _____________________.
What is genetically modified organism.
The __________ controls the use of food additives.
What is the FDA.
What is paper, glass, plastic, metal.
The cooking of food to extreme temperatures to kill micoorganisms, destroy enzymes, and improve shelf life.
What is heating.
The dry and tough spots found on frozen products is called ____________. What causes it?
The main benefit of using radiant energy to preserve food is?
What is- wavelengths are capable of damaging microorganisms such as those that contaminate food or cause food spoilage and deterioration.
____________ are substances added to food to slow down or prevent food spoilage and maintain food freshness.
What is preservatives.
The three main goals of food packaging.
What is- protect food, communicate between manufacturer and consumer, marketing tool
What is fermentation.
Explain the drying curve.
What is- water is lost rapidly at first because it is being lost from the surface of the food. Overtime the food develops a dried layer on the outside and traps moisture in the center of the product causing dehydration to slow.
The key factor that influences how fast a product will heat in the microwave is?
What is water content.
The debate on the use of food additives in food products stems from what?
What is- consumer unrest, in the past chemicals have been added to food for unacceptable products.
The storing of food at any temperature between 68*F and 28*F.
What is cool storage.
The preservation of food through invisible energy waves through space.
What is irradiation.
What is- occurs by removing approximately one-third to two-thirds of the water present to reduce weight and volume.
Explain genetic engineering and how it has been used in the food industry.
What is- alters the genes in a product in a way that improves yields and efficiencies. It has been used to improve flavors, shelf life, and yield.
Fermentation breaks down __________ and yeasts and produces __________ and CO2.
What is sugar and alcohol.
The difference between the types of primary, secondary, and tertiary containers.
