Why Study Food
Science?
Chapter 2
Personal Benefits
 What
do you put unripe peaches in a
paper bag?
 Why should you put potato salad on ice?
 Why would you put raw pineapple juice
with meat?
 What does soaking celery that has lost its
crispness do?
Exploring Careers
 Scientists,
family and consumer scientists,
food editors, food scientist works for
NASA, airline developing foods and
packaging
 Entry-level jobs = those that don’t require
experience or training
 Entrepreneurs – run businesses of their
own ex. consulting work, freelance writing
and opportunities in a food business
Social Impact
 Scientists
are working on better
preservation and distributing methods
 As populations grow fertile farmland is lost
to housing – worlds population is growing
250,000 daily
 Advances in biotechnology have
developed tougher strains of traditional
food crops.
Biodiversity & Public Health and
Safety
 Biodiversity
= cultivating a variety of
plants and animals.

When creating new strains of organisms for a
few selected traits, scientists try to retain the
hardiness that a plant or animal has
developed over the generations.
 Working
on food supply on being more
nutritionally
• Scientists can determine what vitamins and
minerals should be added to foods in certain areas
Environmental Impacts
 Using
disposable silverware made from
degradable plant starches and then being
able to eat your silverware, saving it from
the landfill.
 Raising plants that are more disease
resistant and require less watering.
 Research continues into energy-and costsaving technologies for processing, storing
and transporting foods.
• Newer packaging – food can be stored without
refrigeration – why is this important?
• Dried food is very light- why would that matter?
Sustainable Farming
 Sustainable
Farming = producing food by
natural methods that fit with local needs and
conditions. Ex. eroding, letting cows graze
 Integrated pest management (IPM) = controls
pests with nonchemical deterrents
• Having harmful insects live along with natural enemies,
keeping the “bad bugs” in check
• Composting plant waste and rotating crops from one
growing season to the next.
