1. Herbs and Spices
2. Herbs and spices Herbs are aromatic leaves or seeds from plants of temperate origin
Spices are aromatic fruits, flowers, bark or other plant parts of tropical origin
While herbs and spices are mainly associated with cooking, they have been used in medicine, as natural dyes, and in the perfume and cosmetic industries
3. Essential Oils Volatile substances that contribute to the essence or aroma of certain plants
Most commonly found in leaves, flowers, and fruits where they occur in specialized cells or glands
Chemically, essential oils are classified as terpenes - type of hydrocarbon
In flowers they attract pollinators
4. Early history of spices Primitive people were attracted to aromas of these plants and found uses for them
Ancient Egyptians used herbs and spices extensively in medicine, cooking, embalming, and as perfumes and incense.
Ebers Papyrus dated about 3500 years ago is a scroll that lists the medical uses of many plants
5. Ebers Papyrus Anise, caraway, mustard, saffron and many others
Cinnamon and cassia also mentioned in Egyptian records
These two spices, native to Southeast Asia and China, are evidence that an active spice trade was already in existence
6. Ancient Greek trade During ancient Greek civilization, the spice trade was flourishing between the Mediterranean region and the Far East
Spices such as the cinnamon and cassia as well as black pepper and ginger from India
Arab merchants brought the spices by caravan from India, China, and Southeast Asia (Spice Islands in East Indies)
7. The Roman spice trade Spices were even more prominent in the Roman Empire
After first century, Rome began trading directly with India by ship, breaking the centuries-old Arab monopoly
When Rome fell in 476 A.D. the spice trade virtually disappeared
Centuries elapsed before the spice trade actively resumed
8. Dark Ages Exotic spices from the East were rare
Europeans had to rely on native temperate herbs and many valued for medicinal uses
Merchant travelers kept a limited supply of spices from the Arab trading centers
Crusades, beginning in 1095, increased the spices from the Near East
9. Marco Polo Venice and Genoa rose in 12th and 13th century
Venetian who influenced spice trade - Marco Polo
Traveled to the court of Kubla Khan in China in 1271 and spent 25 years in the Orient - saw its riches and wrote about it on his return
Increased European desire for spices
Lured more and more travelers eastward
New overland routes were established and soon explorers were searching for sea routes to the East
10. Henry the Navigator Prince Henry of Portugal wanted to break the Venetian-Muslim trade monopoly
He established a school of navigation in 1418 to find a sea route to the Orient
His efforts laid the ground work for the Age of Exploration
11. Age of Exploration In 1486 Bartholomew Dias discovered the Cape of Good Hope at the southern tip of Africa, proving a sea route to India was possible
Vasco da Gama made the possibility a reality when he reached the west coast of India in 1497
12. Christopher Columbus Sailed west in search of spices of the East
He was convinced that he had discovered the route to China and Japan.
Christopher Columbus never found black pepper and cinnamon, but he firmly establish Spain's claim to the New World
He did introduce many plants including yams, sweet potato, cassava, kidney beans, maize, capsicum peppers, and tobacco
13. Ferdinand Magellan Portuguese Ferdinand Magellan, also sailing for Spain, led the expedition that circumnavigated the globe (1519-1522) and discovered a western route to the Spice Islands
14. Imperialism - Portuguese control During the 16th century, Portugal monopolized spice trade through its outposts in India, China, Japan and the Spice Islands
The Portuguese were ruthless in their control, often enslaving native populations to labor in the plantations.
Price of spices soared throughout Europe, and the revenues brought tremendous wealth and power to Portugal
15. Dutch control Dutch and English broke the Portuguese control early in the 17th century
By 1621 the Dutch forced the Portuguese from the Spice Islands
Dominant force in the East Indies, Ceylon, and the Persian Gulf spice markets
Even harsher than the Portuguese
To inflate prices of nutmegs and cloves, uprooted 75% of trees on the Spice Islands.
16. English control In the later half of the 18th century the Dutch monopoly began to break down
British and French began spice plantations in their own colonies
By the end of the 18th century, 200 years of Dutch control ended
Early in 19th century the English East India Company had control over most of the spice-rich Orient
17. No more spice monopolies In the 19th century spice monopolies had ended
Decentralization of the spice trade had begun and a spice monopoly would never occur again
18. New World Discoveries The New World spices, introduced first to Spain, included allspice, vanilla, and several varieties of capsicum peppers such as chili peppers and paprika.
19. Old World Spices Cassia ------------------------------ bark
Cinnamon ------------------- inner bark
Cloves ---------------------- flower bud

Outer layer of the bark is scraped away and inner bark curls into quills
Pieces and trimmings ground
22. Cassia The similar spice also called cinnamon comes from several related species, but primarily Cinnamomum cassia native to Southeast Asia
Entire bark is used to make the quills
In US much of cinnamon may actually be cassia
23. Black and white pepper From dried berries of Piper nigrum

27. Cloves
28. Nutmeg and mace Two spices from fruit of a single plant
Nutmeg tree - Myristica fragrans native to the Spice Islands in the East Indies
Apricot-like fruit with a fleshy mesocarp
Inside mesocarp is an aril-covered endocarp
Aril is a thin red net-like covering around the endocarp
30. Nutmeg and mace - the spices Aril dried and ground as spice mace
Stony endocarp and seed dried until the seed rattles
Seed is nutmeg - sold whole or ground
Both spices have similar properties with a strong, spicy but slightly bitter, aromatic flavor and are used in baking sweets as well as meat and vegetable dishes
31. Hallucinogenic properties Both nutmeg and mace - hallucinogens.
Large quantities of either spice must be consumed.
Essential oils contain hallucinogens, but because of the toxicity of these compounds, the hallucinations are accompanied by many unpleasant side effects including nausea, vomiting, dizziness, and headaches.
32. Nutmeg and Mace in history Not known to ancient western civilizations
Reached Europe by the 12th century and were two valued spices of the Middle Ages
Yankee traders in the 19th century developed a scam by producing fake wooden nutmegs which they sold as the real thing - Connecticut- "Nutmeg State"

Three-parted stigmas carefully removed
Speed important before the petals wilt
Traditionally done by hand
Stigmas dried by slow roasting and sold as either saffron threads or powdered
39. Harvesting
40. Most costly spice Stigmas from 75,000 to 100,000 flowers for one pound of the spice.

41. New World Spices Allspice -------------------------- fruit
Capsicum peppers ----------- fruit
Vanilla --------------------------- fruit
42. Capsicum peppers Discovered by Columbus and introduced to Spain
Capsicum fruits as pungent as the Oriental black pepper
He believed that his voyage west in search of spices had been justified
43. Early history of Capsicum peppers Cultivated for thousands of years in tropical America
Exact time of domestication not known
Fragments of a 9000 year old chili pepper were discovered in a Mexican cave
After their introduction to Spain, spread throughout Europe, Asia, and Africa
44. Botany Fruits of genus Capsicum, several cultivated species and hundreds of varieties
Member of Solanaceae (tomato family)
Fruits are berries - immature fruits green and mature fruits vary from yellow to purple to red, from long narrow to spherical
Capsicum annuum most widely cultivated
sweet bell peppers ---> hot peppers
Capsicum frutescens mainly in the tropics - more fiery taste such as tabasco pepper
45. Capsaicin Biting taste due to the amount of capsaicin
Found in the seeds and placental area
Capsaicin content is negligible in the sweet bell peppers and high concentrations in hot chili or jalapeno peppers
Capsaicin can be tasted in concentrations as low as one part per million
Utilized as a pepper spray
Used in creams for localized pain relief
46. Peppers and vitamin C Excellent sources of vitamin C
One pepper is more than enough to satisfy the daily requirement
Higher in peppers than in citrus fruits
Vitamin C was first chemically isolated from paprika in 1932 by Albert Szent-Gyorgyi, who won a Nobel Prize in 1937
47. Capsicum peppers as a spice Sold whole, either fresh or dried
Powders are prepared by grinding the dried fruits
Chili powder - a blend of spices in addition to the ground chili peppers
Used internationally
48. Vanilla Only spice obtained from an orchid
Vanilla planifolia, a perennial vine native to the humid tropical rain forests of Central America and Mexico
Produces elongate pods which are processed into the vanilla beans

Named for its multi-faceted flavor - similar to a combination of cinnamon, nutmeg, and cloves
Never successfully cultivated outside the Western Hemisphere
52. Herbs Herbs are usually the aromatic leaves or sometimes seeds of temperate plants
Other organs may also be herbs
Throughout the centuries, thousands of plants have been used as herbs for both cooking and medicinal properties
Four well known families - mint, parsley, mustard, and lily
53. Mint family - Lamiaceae Herbaceous plants and small shrubs
square stems
aromatic simple leaves with numerous oil glands
Dried leaves or distilled oils used
Mediterranean region an important center of origin for family
54. Mint family - Lamiaceae spearmint
peppermint
marjoram
oregano
rosemary sage
sweet basil
thyme
savory
55. Basil Rosemary
56. Parsley Family - the Apiaceae Annual, biennial, or perennial
Recognized by their umbels (flat-topped inflorescences) and compound leaves
Characteristic fruit - schizocarp
dry indehiscent fruit which splits into two one-seeded identical halves
commercially referred to as seeds
Useful parts are fruits (seeds) or dried leaves or both
57. Parsley family - the Apiaceae parsley
caraway
dill
fennel
celery anise
coriander and cilantro
cumin
chervil
58. Dill
59. Mustard family - the Brassicaceae Many vegetables: cabbage, broccoli, cauliflower, brussel sprouts, turnips, and radishes
Two flavorful herbs - mustard and horseradish
Family especially abundant in the Mediterranean area
Family easily recognized by flowers with four petals arranged in a cross
60. Mustard From Brassica nigra and B. alba seeds
B. alba, white mustard, milder than B. nigra, black mustard
Marketed as whole and ground seeds
Taste result of reactions between:
sinigrin and myrosin in black mustard
sinalbin and myrosin in white mustard
these react to produce volatile oils - unless acidified they quickly deteriorate
61. Horseradish Use as a condiment since the Middle Ages in Denmark and Germany
Prepared from taproots
Taste due to the interaction of sinigrin and myrosin which produce volatile oil
When the roots are scraped or grated the components interact
Volatile oil diffuses easily
62. Lily Family - the Liliaceae Herbaceous perennials that arise from rhizomes, bulbs, or corms
A single genus, Allium from central Asia, is the source of many familiar herbs:
onions - A. cepa
garlic - A. sativum
leeks - A. porrum
shallots - A. ascalonicum
chives - A. schoenoprasum
63. Onions and garlic Onions - biennial producing a single large bulb
Garlic - perennial with a composite bulb
each clove called a bulblet
Pungent flavor due to volatile sulfur compounds that are released when the tissues are cut
garlic -- allicin
onion -- lacrimatory factor
65. Medical use Ebers Papyrus listed 22 uses of garlic for various ailments
In both India and China, onions and garlic used for numerous conditions
Modern research has shown these folk remedies have a sound scientific basis
sulfur compounds in garlic inhibit the growth of disease causing bacteria & fungi
inhibit the formation of blood clots
66. Summary Essential oils are volatile substances that contribute to the essence, the aroma or flavor, of herbs and spices
Desire for spices had a significant impact on world exploration, colonization, and trade
In temperate regions the use of herbs goes back to prehistoric time
Four families provide the majority of herbs in use today
