Partial chemical and functional characterization of milk whey products obtained by different processes

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Whey protein samples (S-1 to S-5) were tested in vivo and in vitro for nutritional properties and selected bioactivities. Weanling male Wistar rats fed modified AIN-93G (12 g protein. 100 g(-1)) diets for 21 days were used the in vivo studies. The nutritional parameters did not differ among the protein diets tested. Erythrocyte glutathione content was considered high and was higher for S-3, but liver glutathione was the same for all dietary groups. For S-3, cytokine secretion (IL-10 and TNF-alpha) by human peripheral blood mononuclear cells (in RPMI-1640 medium) was higher in the absence of antigen than in the presence of BCG antigen. Interleukin-4 secretion was repressed in all treatments. The IC50, whey protein concentration required to inhibit 50% of the melanoma cell proliferation, was 2.68 mg.mL(-1) of culture medium for the S-3 sample and 3.66 mg.mL(-1) for the S-2 sample. Based on these results, it was concluded that S-3 (whey protein concentrate enriched with TGF-beta and lactoferrin) produced better nutritional and immunological responses than the other products tested.3215664Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)CIPED (Pediatrics Investigation Center of the University of Campinas)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Guar gum effects on food intake, blood serum lipids and glucose levels of Wistar rats

The effects of guar gum derived from the endosperm of Cyamopsis tetragonoloba (75% soluble fiber, 7.6% insoluble fiber, 2.16% crude protein, 0.78% total lipids, 0.54% ash and 9.55% moisture) on food intake, levels of blood serum cholesterol, triacylglycerols, glucose and LDL and HDL-cholesterol were studied. The effects of guar gum on indices of protein absorption and utilization were also investigated. Diets containing 0%, 10% and 20% (w/w) guar gum or 10% and 20% cellulose powder (reference) were fed to normal rats for 60 days. The rats fed the guar gum diets showed significantly (p less than or equal to 0.05) lower levels of blood serum cholesterol, triacylglycerols, reduced food intake and body weight gain. Furthermore, a concomitant increase in HDL-cholesterol with a substantial elevation of the HDL/LDL cholesterol ratio were noted. Guar gum decreased blood serum glucose only during the first month of the experiment, and no changes in the indices of protein absorption and utilization were found. The guar gum caused a 10% increase in the small intestine length and a 25% retardation in the intestinal transit. The results of this research suggested that guar gum could potentially be effective in the treatment of hypercholesterolemia and obesity in humans.531152
