Study of the proteins in the defatted flour and protein concentrate of baru nuts (Dipteryx alata Vog) 116
Guimarães,Rita de Cássia Avellaneda; Favaro,Simone Palma; Viana,Antonio Camilo Arguelho; Braga Neto,José Antônio; Neves,Valdir Augusto; Honer,Michael Robin.
Baru (Dipteryx alata Vog.) is an abundant legume in the Brazilian Savanna. Its nuts can be exploited sustainably using its protein and lipid fractions. This study aimed to analyze the proteins of the nuts present in the defatted flour and protein concentrate in terms of their functional properties, the profile of their fractions, and the in vitro digestibility. The flour was defatted with hexane and extracted at the pH of higher protein solubility to obtain the protein concentrate. The electrophoretic profile of the protein fractions was evaluated in SDS-PAGE gel. The functional properties of the proteins indicate the possibility of their use in various foods, like soybeans providing water absorption capacity, oil absorption capacity, emulsifying...

Effect of chickpea (Cicer arietinum L.) germination on the major globulin content and in vitro digestibility 116
Portari,Guilherme Vanucchi; Tavano,Olga Luisa; Silva,Maraiza A. da; Neves,Valdir Augusto.
Chickpea seed germination was carried out over a period of 6 days. Little variation in the nitrogen and total globulin content was observed. The major globulin (11 S type) showed higher variation after the 4th day of germination. The elution behaviour and distribution of the isolated major globulin fraction on Sepharose CL-6B chromatography showed little modification at the end of germination. On SDS-PAGE the peak eluted from Sepharose CL-6B showed changes in protein bands between 20 and 30 kDa and above 60 kDa, indicating protein degradation during the period. Proteolytic activity was detected in the albumin fraction of the seeds, which increased up to the fourth and then decreased up to the sixth day, when isolated chickpea total globulin and casein were...

Genetic variation and environmental effects on beta-conglycinin and glycinin content in Brazilian soybean cultivars 86
Carrão-Panizzi,Mercedes Concórdia; Kwanyuen,Prachuab; Erhan,Sevim Zeynep; Lopes,Ivani de Oliveira Negrão.
The objective of this work was to determine genetic and environmental effects on beta-conglycinin and glycinin content in Brazilian soybean cultivars. The concentrations of these protein fractions were analyzed by scanning densitometry after electrophoresis, in 90 Brazilian soybean cultivars sown in Ponta Grossa, PR, in 2001. The effects of the sowing location were determined in the cultivar MG/BR 46 (Conquista), sown in 16 locations of Goiás and Minas Gerais states (Central Brazil), and in the cultivar IAS 5, sown in 12 locations of Paraná and São Paulo states (Southern Brazil), in 2002 soybean season. A significant variability for beta-conglycinin (7S) and glycinin (11S) protein fractions ratio was observed among the 90 Brazilian soybean cultivars....
