Study Notes
Food Scientist Role in Food Development
- Food scientists develop nutritious, palatable, and low-cost food products.
- Examples include:
- Dried milk: A less expensive alternative to fresh milk, but not as readily digested by all.
- Fish "flour": A cheaper source of protein made from fish species not commonly consumed.
- Incaparina: A cereal formulation containing 28% protein made from maize, sorghum, and cottonseed flour - low-cost crops grown in Central and South America.
- Food scientists adapt materials and methods for different regions of the world.
Food Scientist Role in Space Food
- Food scientists are involved in developing food for space programs.
- Space food must be:
- High quality
- Appetizing, even when astronauts' taste buds change in space.
- Safe
- Easy to prepare and eat in a confined space with limited heating options.
- The Space Food Systems team ensures each crew member's nutritional needs are met while considering space, preparation, and gravity limitations.
- Food plays a critical role in astronauts' social and psychological well-being during space travel.
Food Scientist Role in Altering Food Composition
- Food scientists alter food nutrient content, particularly reducing calories or adding vitamins and minerals.
- Examples:
- Soft drinks: Replacing sugar with aspartame (Nutrasweet) - same calories but 200 times sweeter.
- Low-fat ice cream: Removing milk fat and adding specially treated proteins.
- Daily cereals: Adding vitamins and minerals without affecting flavor or appearance.
- Examples:
Food Scientist Role in Food Processing and Storage
- Food scientists design and operate ships that process fish at sea.
- This includes automatic separators for small and large fish, mechanized cooling tanks, oil extractors, ice makers, canning factories, and equipment for preparing fillets, cakes, dehydrating fish, and making dried fish meal.
- These factories can operate at sea for two months or more.
- Food scientists develop controlled atmosphere (CA) storage for food and vegetables.
- They also develop quick-freezing methods for delicate food using liquid nitrogen, carbon dioxide, or other low-temperature liquids.
Food Scientist Role in Food Safety
- Food scientists work to make food as safe as possible.
- They study outbreaks like:
- The 1993 hamburger outbreak involving undercooked ground beef and E. coli O157:H7.
- Salmonellosis (Salmonella enteritidis) from eggs and poultry.
- They develop methods to prevent future outbreaks through proper food processing.
Food Scientist's Role In Food Development
- Food scientists focus on developing palatable, nutritious, and affordable food products.
- Examples include:
- Dried milk: Offering an alternative to fresh milk, though more expensive and potentially harder to digest.
- Fish "flour": Utilizing less commonly consumed fish species for a cheaper source of protein.
- Incaparina: A cereal blend with 28% protein, incorporating maize, sorghum, and cottonseed flour.
- Food scientists adapt and develop food production methods and materials suitable for diverse regions and economic situations.
Space Food Systems
- Food scientists play a crucial role in developing space shuttle food.
- Space food requirements:
- High quality and appetizing, even with altered taste buds in space.
- Safe and easy to prepare in confined spaces with limited heating options.
- Meeting nutritional needs of the crew with limited storage and preparation capabilities.
- Food has a significant social and psychological role during space travel.
Altering Nutrient Content
- Food scientists work to modify food's nutritional profiles.
- Examples:
- Reducing calories: Replacing sugar with aspartame in soft drinks, providing 200 times the sweetness with fewer calories.
- Adding vitamins and minerals: Fortified cereals and low-fat ice cream.
- These additions must be done without compromising taste or appearance.
Food Processing Technology
- Food scientists are involved in designing and operating ships for processing fish at sea.
- This includes:
- Automated fish separation systems.
- Mechanized fish cooling tanks.
- Automatic oil extractors.
- Ice-making equipment.
- Complete canning facilities.
- Equipment for preparing fish fillets, cakes, dehydrated fish, and fish meal.
- These vessels can operate for extended periods, up to two months or more.
Food Preservation and Safety
- Food scientists develop advanced food preservation techniques.
- Controlled atmosphere (CA) storage for fruits and vegetables.
- Quick freezing with liquid nitrogen, carbon dioxide, or other low-temperature liquids.
- Focus on food safety through proper processing methods.
- Examples of foodborne illness outbreaks:
- E. coli O157:H7 outbreak in 1993 linked to undercooked hamburgers.
- Salmonellosis (Salmonella enteritidis) outbreaks linked to eggs and poultry.
- Food scientists research these outbreaks to prevent future occurrences through enhanced food processing techniques.
