Document Summary

Bean or pea family (3 subfamilies: mimosaceae: acacia, leucaena, mesquite, fabaceae, caesalpiniacaea: senna, carob, redbud. Fabaceae (leguminosae: cosmopolitan (warm tropical regions, all produce a legume (pod form from carpel) Pulses: dried seeds of legume use a food eg. lentil, peas. Symbiosis relation with rhizobium bac in root (fix n2 to nh4, nitrogenase) Leghemoglobin: produce by plants infected with bac, keep o2 level low so nitrogenase not affected. Nitrogen fertilizer: energy intensive, from industrial process, with increase energy cost, movement to grow more legumes. Chick peas: spread east to india and west mediterranean. Soybean: domest in china 3000yrs, needs warm climate, moderate rain, 2nd highest pr+ after carob, good aa balance, contain phytoestrogen. Tempeh fermented soybean cake: staple source of pr+ in indonesia. Miso: mixture of soybeans, salt, rice fermented by fungi. Common bean (phaseolus vulgaris: originate in central/south america, pr+ analysis reveal species intro more than once. Lima beans (phaseolus lunatus) relative to common bean, mainly in dry form.
