Pulses or legumes

Pulses or legumes

Peas and Beans


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


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
