Membranes can be used to recover whey proteins?

With this study it was possible to recover 80% whey proteins using membrane of 10 kDa. These proteins showed good protein solubility, emulsion stability, and most were identified as β-lactoglobulin (18.3kDa) and α-lactalbumin (14.2kDa). Therefore, the use of membranes is an alternative to recover whey proteins in the industrial process. Read More →

Study genotypes southwestern Chinese wheat varieties

Through the genotyping of 138 samples, researchers mapped two groups of wheat varieties from southwestern China. Group I presented non-T6VS/6A1 lines from different origins, while group II presented T6VS/6A1 lines, most of which originated from Guizhou, China. The study, conducted by researchers at the Suranaree University of Technology in Thailand and the Guizhou Academy of Agricultural Sciences in China. Read More →

Will the Brazilian Unified Healthcare System (SUS) survive another 30 years?

In this troubled year of 2018, Brazil celebrates two ephemerides: the 30 years of the Magna Carta, the Citizen Constitution, and the 30 years of the Health Unified System (SUS – Sistema Único de Saúde). To celebrate this latest date, the journal Ciência e Saúde Coletiva (vol. 23, no.6) presents a very rich and diverse collection of materials that discusses the advances, limitations and challenges faced by SUS over the last three decades. In this thematic edition, the Unified Health System is scrutinized in the most different ways regarding its qualities and deficiencies. Read More →
