Enzyme extraction of cupuassu (Theobroma grandiflorum S.) fat sedes

Enzyme-assisted extraction is considered an environmentally friendly technique. Cellulase, pectinase and protease were tested for cupuassu seeds fat extraction. The best fat efficiency (81.66%) was obtained for the solute:solvent 1:5 (m:w), orbital shaker at 120 rpm, 60 °C, for 8 hours and enzyme concentrations (cellulase, pectinase and protease) of 1.0%. The fat was characterized for physicochemical properties, fatty acid profile, phenolic compounds, antioxidant activities and oxidative stability. The fat showed good thermal stability (14.26 h) and high contents of monounsaturated (42.42%) and saturated (43.47%) fatty acids with higher concentrations of oleic and stearic acids, respectively, and a high content of phenolic compounds (141.84 µg EAG·g-1) in the fat, and in the aqueous extract (926.47 µg EAG·g-1). The results indicated that the cupuassu seed fat obtained by enzymatic extraction showed superior properties to cupuassu fat obtained by cold pressing, in addition to generating an aqueous fraction which is rich in bioactive compounds that can be used as ingredients in the food and pharmaceutical sectors

RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true
