Acreage harvested among countries: 0.04-3.8 Mil ha). • Poland is number 1 in production (5.66 MMT), followed by • Germany (4.78 MMT), and Russia (3.30 MMT). • Major exporter: Canada.

  9. Sorghum: 1998/99 Estimate • Yield varied from 0.3 MT/ha (Niger) to 4.53 MT/ha (Argentina). • Nigeria (6.6 Mil ha) and Sudan (5.2 Mil ha) are number 1 and 2 in • the world in acreage harvested. US is 3rd in acreage harvested. • US is number 1 in production of sorghum (13.21 MMT). Nigeria is a • distant second (7.30 MMT) in the world.

  10. Rice: 1998/99 Estimate • Yield varied from 1.87 MT/ha (Nigeria) to 8.96 MT/ha (Egypt). • India is number 1 in acreage harvested (43.42 Mil ha) followed by • China (31.77 Mil ha). • China (140.49 MMT) and India (82.30 MMT) are number 1 and 2, • respectively, in production. • Major exporters: Vietnam, Thailand, Burma, and Pakistan. • Major importers: EU, Indonesia, South Korea, Iran, and Nigeria.

  11. Soybeans: 1997/98 Estimate • Yield varied from 0.69 MT/ha (Russia) to 2.76 MT/ha (Argentina). • US is number 1 in acreage harvested (27.97 Mil ha), followed by • Brazil (13 Mil ha). • US (73.18 MMT) and Brazil (32.50 MMT) are number 1 and 2 in • production. • Major exporters: Argentina, Brazil, Paraguay.

  19. Utilization of Grains in the US

  20. Wheat • Processes about 36% of its total wheat produced. About 25-42% is exported. • End uses: • Flour (various types and blends). • Animal feed • Wheat starch (fruit pie fillings, gravy mixes, adhesives, syrups) • Amylose in starch: biodegradable films (sausage casings).

  21. Corn • About 63% consumed as animal feed (grain, silage, corn gluten meal, various extruded feeds). • 21% exported. • 16% for food, alcohol, and industrial purposes. • 0.2% for planting seed.

  22. Barley • Animal feed (hay, silage, and swine feed; B-glucans reduce cholesterol in chickens) • Brewing • Human food (popped, barley flakes, sprouts, sweeteners, malt, infant food syrups)

  23. Oats • Mostly used as livestock feed. • High protein unlike barley. • Hot cereals, cold cereals, bread products, cookies, infant foods. • High in soluble fiber.

  24. Sorghum • Wet milling: gluten and starch. • Syrups from starches. • Dry milled products used for making “tortilla” type products. • Ethanol (1 bu produces 2.5 gal. of alcohol). • Beer and malt. • Blended with other flours for baked and pasta products

  25. Rice • Food (consumption in US increasing). • Directly as cooked rice. • Processed foods (cereals, soups, baby food, etc.). • Brewing (beer). • Rice bran and germ as livestock feed. • Rice hulls as poultry littering material.

  26. Rye • Rye flour for bread, snack type crackers, pan cake, waffle mixes. • Whiskey. • Manufacture of paper. • Adhesives • Straw for animals. • May contain poisonous substances (ergot, resorcinols, phytates, and enzyme inhibitors).

  27. Soybeans • Various soy foods • Soymilk, tofu, Yuba. • Fermented foods • Soy paste, sauce, tempeh, • Oil (20% oil mc-free basis) • Defatted meal (40% protein mc-free basis) • 1 MT of soybeans = $ 160 of meal & $ 80 of oil. • Burgers

  28. References on Utilization of Cereal Grains • Lorenz, K, J. and K. Kulp. (Eds.). 1991. Handbook of cereal science and technology, Marcel Dekker, Inc. New York, 882 pp. • KeShun Liu. 1997. Soybean: chemistry, technology, and utilization. Chapman and Hall, New York, 532 pp.

  29. Harvest and Storage of Grain • Harvest occurs once. • Storage occurs multiple times after harvest. • Raw grain: Farm to processor. • Processed grain: Processor to consumer. • Deterioration can occur anywhere throughout this continuum (harvest to consumption).

  30. Stored-Grain Ecosystem • Ecosystem = Ecological system. • Artificial, transient ecosystem. • Biotic community, abiotic environment, and their interactions. • Population: A group of individuals of a species. • Habitat: Designated area (bag of seed, silo, many silos, etc.)

  31. Stored-Grain Ecosystem: Objectives • Preserve maximum amount of the harvested crop in the best possible condition for the longest time. • Quantity, quality, storability.

  32. Decomposition of Stored Grain • Differences between Less developed or developing countries and developed countries.

  33. Management of Stored Grain in Developing Countries • Wide variety of structures used. • Climatic conditions conducive for biological organisms that cause spoilage. • Low income of the farmers. • Lack of knowledge and training.

  34. Management options for small farmers • Waterproofing granaries (flood and rain water). • Rodent-proofing. • Cleaning (structures and grain). • Drying (12-13%). • Cooling (proper building materials to reduce natural radiation). • Protectants. • Regular inspections.

  35. Traditional Storage Systems

  36. Underground Storage Systems

  37. Storage Systems in Developed Countries

  38. Reading Assignment • Chapters 4 (Development of storage techniques) and 5 (Whole grain storage) from D. B. Sauer’s Book.
