2. Pepper Daniel Pinkwater “It doesn’t matter who you are, or what you’ve done, or think you can do. There’s a confrontation with destiny awaiting you. Somewhere, there is a chili you cannot eat.”

3. Pepper Consumer use Pungency Due to a single compound – capsaicin Present in the septa and placenta Controlled by a single gene Detectable at 1 ppm “Paprika” flavor due to the compound capsanthin

4. Pepper Consumer use Pungency Varies widely among types and varieties Measured using “Scoville units” Bell 0 units Ancho 1,000 units Jalapenos 5,000 units Yellow wax 10,000 units Tabasco 160,000 units Habaneros 200,000 units

5. Caribbean Red Habanero, rated 400,000 on the Scoville scale

6. Pepper Species used for food Capsicum annuum Origin – Columbia, Central America, SW N. America Worldwide production Includes most of the common sweet and hot peppers Bell Jalapeno Wax Cayenne Serrano

7. Pepper Species used for food Capsicum frutescens Origin – Amazon, relatedto C. chinense Grown in China and tropical America Considered to be semi-domesticated Includes “Tabasco”, Thai, and malagueta peppers

8. Pepper Species used for food Capsicum chinense Origin - Amazon Includes the most pungent of all peppers Habanero Naga Datil (includes naga varieties of over 1,000,000 Scoville units)

9. Pepper Species used for food Capsicum baccatum Origin – Bolivia Unique fruity flavor Includes aji (Peruvian puff) peppers Use limited to South America

10. Pepper Species used for food Capsicum pubescens Origin - Central America and Andes Use limited to areas of origin The “goat chili”, adapted to cool highland climates

11. Pepper types and varieties

12. Pepper Use and importance The predominant worldwide spice crop Emerged as a replacement for expensive black pepper Produced and consumed throughout the world Largest production is in Asia and Africa Important source of vitamin A, vitamin C and many minerals

13. Worldwide pepper production

14. Pepper drying in Korea

15. Pepper Consumer use Spices Paprika – dried and ground non-pungent peppers Chili powder – dried and ground pungent peppers mixed with oregano, cumin, garlic Curry – dried and ground pungent peppers mixed with turmeric, cumin, coriander

16. Pepper Production Systems/Market Opportunities Produced worldwide in subsistence and market garden systems Excellent subject for local market sales, organic production Modern intensive production common in the warmest temperate and dry sub-tropical climate in both the northern and southern hemisphere Fresh markets, contract for processing, spices

17. Pepper morphology

18. Pepper Taxonomy Dicotyledon Family: Solanaceae Genus and species: Capsicum annuum Related species: tomato, potato, nightshade

19. Pepper Domestication Endemic to tropical and subtropical America Evidence in Mexico earlier than 5000 BC Spread throughout the world by Spanish and Portuguese traders

20. Pepper Fruit set Temperature sensitive Pollen death and abscission >90 or <60 Optimum set at 70-80 Drought stress causes flower drop Long-term temps higher than 95 cause abnormal fruit growth

21. Pepper Production Problems Subject to many of the diseases and insect problems common to tomatoes Pest problems do not tend to limit production in warm climates

22. Pepper Harvest Harvest Indices Green Harvest (salad or green-processed use) Desired size, lack of color change, waxy surface Mature harvest (dried and/or ground use) Fully developed color (yellow, orange, or red) Attached pedicel Firmness retained for processed Partially desiccated for dehydration

23. Why did the tomato blush?

24. Why did the tomato blush? It saw the salad dressing.

25. Eggplant (Brinjal) Taxonomy Dicotyledon Family: Solanaceae Genus and species: Solanum melongena Related species: potato, tomato, pepper, nightshade

26. Eggplant Botany Short-lived perennial, grown as an annual Bush-type growth 2-8 feet in height Fruit are round, pear-shaped, or elongated Fruit is a berry without a cavity Internal texture is due to spongy placental tissue Wild type fruits are bitter and spiny

27. Eggplant

28. Eggplant

29. Eggplant Origin and Domestication Native to India Center of diversity in Bangladesh and Myanmar Spread to China by 500 BC Taken to Africa and Spain by Arabic traders

30. Eggplant Importance and use Predominantly a product of subsistence and market garden agriculture A staple crop in many tropical Asian countries

31. Eggplant Importance and use Largely used as a fresh market vegetable Seldom processed or eaten raw Prepared boiled, baked, fried, and stuffed Few calories but important source of protein, vitamin A, minerals

32. Eggplant Varieties Many types Oval or round, dark purple - most common Black Beauty, Florida Market, Classic Other countries produce white, yellow, brown, and green types with round, oval, pear-shaped, and long shapes China produces decorative types with scarlet fruit

33. Eggplant Range of types

34. Eggplant Harvest and Storage Edible when 1/3 to fully grown Best quality when about 1/2 to 2/3 full size Thumb-press test Retention of glossy surface Hand harvested Continuous harvest necessary to maintain production

35. Pepino fruit

36. Other Solanaceous Fruits Pepino Species: Solanum muricatum Perennial from Ecuador and Peru Bear for several years once established Immature fruit are cooked Mature fruit are eaten raw as a dessert (sweet, with a cucumber flavor) Market garden production on South America Ethnic markets in Australia, New Zealand, US

37. Tamarillo fruit

38. Other Solanaceous Fruits Tamarillo (tree tomato) Species: Cyphomandra betacea Native of Peru (Andes) Perennial shrub up to 15 feet tall Usually cultured for 5-6 years, then replaced Acidic, tomato-like flavor Usually stewed or juiced, can be eaten raw Export production in New Zealand, Portugal; market garden and subsistence elsewhere

39. Tomatillo fruit

40. Other Solanaceous Fruits Tomatillo (husk tomato) Species: Physalis philadelphica Mexican origin Annual plants up to 3 feet tall Fruit becomes less acid and sweeter at maturity Macerated immature fruit are used for sauces (salsa verde) and other purposes Market garden in Latin America, widely grown in Europe

Other Solanaceous Fruits Naranjilla (Lulo) Species: Solanum quitoense Native of Ecuador and southern Columbia Perennial semi-shrub 3-6 feet tall, grows best in shade Acidic, whitish-green flesh, flavored like orange, pineapple, and tomato Popular for juices, preserves, and desserts Local production in Central and South America
