– Discuss America's culinary heritage
– Explain the main elements in receiving and storing
perishable and nonperishable items
– Describe the key points in food production
– Discuss the various types of food poisoning and
how to avoid them

Our Culinary Heritage
• American cooking
– Formed on a matrix of national cuisines
• The confluence of foods and food preparation methods
from numerous national and racial groups
– English, Italian, Indian, French, Chinese, etc.
– Menus of the Great American Restaurant
• Present foods prepared by methods that are an
amalgam of various cookery styles
– Sharpened by food science, home economics, and the food
section of the daily newspaper
Native American Influence
• Lasting, yet sometimes overlooked, influence
on American cuisine today
– American Indians from the Eastern Woodlands:
• Planted crops of corn, beans, and squash
– Native Americans:
• Diets included several fruits and vegetables
• Also introduced pumpkin, various beans, squash,
peppers, blackberries, raspberries, and tomatoes
• Diets were supplemented through hunting game (e.g.,
venison, rabbit, squirrels, and raccoons)
African American Influence
• Soul food:
– Food traditionally prepared and eaten by African
Americans of the Southern U.S.
– Can be trace back to Africa:
• Slaves brought fruits and vegetables with them to eat
on their journey to America
• The seeds (e.g., watermelon, okra, black-eyed peas,
and eggplant) would have a lasting influence on
American cuisine
Italian Influence
• Italy has a rich culinary tradition
– Offers a variety of foods
• Italians cultivated fine cuisine long before the
French
– Their influences have much in common
• It was from Italy that much of the French fascination
with food came originally
– In the ancient period, wealthy Romans spent
lavishly in time and money on food and drink
French Influence
• Lexicon of cookery
– Reflects the French contribution to the culinary
scene:
• Dishes
• Terms (e.g., blanch, fricassee, and poach)
• Food presentation
• Service
• Sauces (e.g., hollandaise, béarnaise, etc.)
• Most experts rank French cookery near or at
the top of various national cuisines

French Sauces and Seasonings
• Sauces: hallmarks of the French cook
– Particularly those thickened with roux
• Equal quantities of fat and flour
• Five “mother” or leading sauces:
–
–
–
–
–
Béchamel
Velouté
Espagnole
Tomato
Hollandaise
French Sauces and Seasonings
(cont’d.)
• Younger French chefs have invented ways of
avoiding calories while retaining flavor
– Fresh foods, lower fat, and the avoidance of rouxthickened sauces are being featured
• Called Nouvelle Cuisine (New Cuisine) and Cuisine
Minceur (pronounced man sir, “cuisine of thinness”)
• Instead of roux-thickened sauces, pureed fruits and
vegetables are used
• Liquids are reduced by cooking to appropriate
thickness
Receiving
• Smart restaurateurs arrange with suppliers for
all deliveries to be delivered at times
convenient to the restaurant
– Copy of the order should be available for the
receiver
• Checks quality and quantity accuracy
– Management should check and sign for all
deliveries
• Few restaurateurs have the time to check all items, so
they check the higher-cost items
Storage
• Should be arranged for easy receiving, issuing,
and inventory control
– Dry-goods storeroom: canned, packed, and bulk
dry foods are stored according to usage
• Most-used foods: stored closest to the door
• Least-used foods: stored in the less accessible corners
and shelves
– Rotational system:
• As foods are received, they are stored at the backs of
shelves
• Older items are moved forward to be used first
Storage (cont’d.)
• Systems:
– Last-in, first-out (LIFO) system
• Costs the item at the price paid for the merchandise
purchased last
– First-in, first-out (FIFO) system
• Uses the price actually paid for the item
• During a period of inflation
– Two costs could be quite different
• Selected method must be used consistently
Food Production
• Kitchen manager, chef, or cook
– Begins the production process by determining the
expected number of guests
• Same period for the previous year gives an indication of
the expected volume and a breakdown of menu item
sales
– Product mix: list of what was sold yesterday
• Gives an indication of what needs to be prepped to
bring the item back up to par level
Food Production (cont’d.)
• Every morning:
– Chef or kitchen manager determines the amount
of each menu item to prepare
• Par levels are checked and a production sheet is
completed for each station
• Production sheets give the quantity of each menu item
to be prepared
• Cooking line:
– Most important part of the kitchen layout
– Kitchen is set up according to what is ordered
most frequently
Production Procedures
• Production in the kitchen
– Critical to the success of a restaurant
• Relates directly to the recipes and how much product is
on hand
– Timing is vital
• Production starts with mise-en-place
– Assembly of ingredients and equipment for the
recipe
• Backbone is having all the specific ingredients for the
recipes prepped ahead of time
Production Procedures (cont’d.)
• Creating production sheets:
– Count the products on hand for each station
– Determine production levels
– Decide on amount of production required to
reach the level for each recipe
– When calculations are completed, sheets are
handed to cooks
Production Procedures (cont’d.)
• Use of production sheets
– Critical in controlling how cooks use products
• Production plays a key role in food cost
• Every recipe has a particular spec to follow
– When one deviates from the recipe:
• Quality goes down
• Consistency is lost
• Food cost goes up
Staffing and Scheduling
• Proper staffing
– Critical for successful running of a kitchen
• Important: have enough staff to enable the restaurant
to handle the volume on any shift
– Often it is better to overstaff the kitchen, rather
than under-staff:
• Much easier to send an employee home than to call
someone in
• Having extra staff on hand allows for cross-training and
development
Food-borne Illness
• United States Public Health Service
– Identifies more than 40 diseases that can be
transferred through food
• Can cause serious illness; some are deadly
– Food-borne illness: disease that is carried or
transmitted to human beings by food
– Types of hazards to safe food: biological,
chemical, and physical
• Biological hazards cause the highest percentage of
food-borne illness outbreaks
Biological Hazards-Bacteria
• Highest number of biological food-borne
illness is caused by bacteria
– Single-celled microorganisms that are capable of
reproducing in about 20 minutes
• Need sustenance to function and multiply
• Can cause illness in two ways:
– Disease-causing bacteria (e.g., pathogens)
– Other bacteria discharge toxins that poison
humans when food containing them is eaten
Biological Hazards-Bacteria
(cont’d.)
• Pathogenic bacteria causes illness in humans
through:
– Intoxication
• Example: botulism
– Infection
• Example: salmonella
– Toxin-mediated infection
• Example: E. coli
Causes of Food-borne Illness
• High protein foods
– Responsible for most food-borne illnesses
• Includes any food consisting of milk or milk products,
shell eggs, meats, poultry, fish, shellfish, edible
crustaceans (e.g., shrimp, lobster, crab, etc.), tofu and
other soy-protein foods, plant foods that have been
heat treated, raw seed sprouts, or synthetic ingredients
Causes of Food-borne Illness
(cont’d.)
• Disease-causing microorganisms:
– Staphylococcus aureus
• Produce enterotoxins that cannot be destroyed
– Salmonella
• 2,000 closely related bacteria
• Continually cycle through intestinal tracts of people
and animals
– Clostridium perfringem
• Bacteria present in soil, intestines of animals and
humans, and in sewage
Controlling or Destroying Bacteria
• In order to grow, bacteria require:
– Food, moisture, proper pH, and time
• Potentially hazardous foods:
– Those high in protein (e.g., meat, milk, and dairy
products)
• Eggs, fish, and shellfish
• Custard, mayonnaise, hollandaise sauce, and quiche
Bacteria and Temperature
• Temperature
– Most important element for bacteria survival and
growth
• Also the easiest to control
• Temperature danger zone: 40°F to 140°F
• Destroying bacteria:
– Heat:
• 180F is used in final rinse of dishwashers
– Chemical sanitation:
• Most effective between 75F and 120F
Viruses
• Do not require a hazardous food in order to
survive:
– Can survive on any food or surface
– Do not multiply
– Not as affected by heat or cold
• Once a virus enters a body cell, it takes over:
– Forcing the cell to assist in production of more
viruses
Chemical Contaminants
• Increased use of pesticides
– Has caused concern about chemical
contamination of foods
• Other types of chemical contamination:
– Restaurant chemicals (e.g., detergents)
– Overuse of preservatives and nitrates
– Acidic reaction of foods with metal-lined
containers
– Contamination of food with toxic metals
Hazard Analysis of Critical Control
Points
• Presents methods for systematically ridding
kitchens of pathogens
• System steps:
– Identify hazards and assess severity and risks
– Determine critical control points in food
preparation
– Determine critical control limits for each CCP
– Monitor CCPs and record data
Hazard Analysis of Critical Control
Points (cont’d.)
– Take corrective action whenever monitoring
indicates a CCL is exceeded
– Establish an effective record-keeping system to
document the HACCP system
– Establish procedures to verify that the HACCP
system is working
Common Food Safety Mistakes
• Key areas of common food safety risks in dayto-day food production:
– Time/temperature
• Keep cool foods below 40F and hot foods above 140F
– Cross-contamination
• Most occurs in food preparation
– Poor personal hygiene
Approaches to Food Safety
• Overall responsibility for foodservice has been
given to the FDA
– Provides a model ordinance that is the basis for
most local health ordinances
• States and local communities monitor restaurants for
cleanliness and adherence to food protection
ordinances
• Public health license to operate a restaurant is
required
– Health officer makes an inspection
Food Protection as a System
• The more sanitation practices built into a
system:
– The more likely they will be carried out
• Personnel trained in the system are carried along by it
• Success of McDonald’s:
– Emphasis on the sanitation system
• Systematize sanitation practices:
– Build them into the manager's daily schedule
