fabaceae
Fabaceae
  • Second most important family for humans
  • A combination of grain and pulses is seen in major civilization
    • Barley and lentils; rice and soybeans; corn and beans
  • Fabaceae is diverse and has about 16,000 species
  • Common features are the flowers and fruits (a legume)
fabaceae1
Fabaceae
  • Three subfamilies
    • Faboideae – main source of pulses (Dried seeds)
    • Caesalpinoidae – tamarind and carob
  • Plants have root nodules
    • increases the nutrients of the soil
    • More protein in the fruits
    • Non-protein amino acids (some toxic)
    • Good rotation crop
nutrients
Nutrients
  • Protein: CHO: fat: fiber are 20:70:8:4 percent.
  • Protein: lack Met and cysteine and some sulfur containing amino acids
  • CHO: raffinose and stachyose series. Hard to digest, flactulence. Alpha –galactosidase from Aspergillas.
  • Fat has unsaturated fatty acids; hihgest in peanuts
nutrients1
Nutrients
  • Non-protein amino acids
  • Some have anti-nutritional factor
  • Protease inhibitor
  • Isoflavone
  • Dissolve fiber
lentils
Lentils
  • Lens culinaris –Shape of eye lens. 25% proteins, 60% CHO, less than 1% fat vit A &B abd calcium
  • Middle East between 8000-9000years ago
  • Domesticated
  • Has most digestible and most commonly eaten pulse
slide7
Peas
  • Pisum sativum
  • Near East and Europe, 8000 – 9500 years old but not sure whether grow or gathered.
  • Brought ot New world by Columbus
  • Eaten fresh
  • Chinese snow peas has low fiber and selected 17th century
  • Sugar snap peas – recent 1979
broad beans
Broad beans
  • Vicia faba: mainly hog feed
  • Middle East origin
  • Favism: hemolytic anemia; due to defective gene; glucose-6-phosphate dehydrogenase; due to vicine that oxidizes and degrades RBC
chickpeas
Chickpeas
  • Cicer arietinum: forage has toxic proteins
  • Near Eastern
  • Do not like cool climates
  • Quality and easily digestible proteins
soy beans
Soy beans
  • Glycine max: Native of China
  • High is proteins sulfur containing ones
  • Isoflavones: genestine; daizein
  • Phytosterols
  • Antivitamins; protease inhibitors; cyanogens; saponins
pigean peas
Pigean peas
  • Cajanus cajan
black eye peas
Black-eye peas
  • Vigna unguiculata
lima beans
Lima beans
  • Phaseolus lunatas/limensis
  • Lima; kidney or garden beans(P.vulgaris); green or mung beans(P. aureus); blackgram (P.mungo)
peanuts
Peanuts
  • Arachis hypogea: pedicles enter the ground for fruit to mature
  • Unique flowering and fruiting
  • 45% oils; 20-25% proteins;
  • South America – origin
  • Mainly used as roasted seeds; peanut butter and oil
tamarind and carob
Tamarind and carob
  • Tamarindus indica
  • Ceratonina siliqua
