The objective of this study was to obtain protein hydrolysate from the mechanically separated meat of blackfin pacu to evaluate the influence by ultrafiltration in the antioxidant and antimicrobial activities of the peptidefractions obtained and to apply in ground beef to evaluate the lipid stability. The enzymatic hydrolysis was performed using the enzyme Protamex (pH 7.0, 60°C) for 240 min. The protein hydrolysate was fractionated by ultrafiltration. Then, the antioxidant capacity of the protein hydrolysate and the peptide fractions were evaluated in vitro by the methods of 2,2?-azinobis (3-ethylbenzothiazoline sulfonic acid) radical capture, 2,2-diphenyl-1-picrylhydrazyl radical-scavenging assay, reducing power, and hydroxyl radical scavenging activity. The antimicrobial activity of the samples was evaluated by disc-diffusion against Staphylococcus aureus and Escherichia coli. After evaluation, the peptide fractions did not present higher bioactivities than that shown for the hydrolysate. The protein hydrolysate was applied to ground beef, where the substances reactive to thiobarbituric acid and color were evaluated during 7 days of storage at 4°C. Lipid oxidation was reduced up to 60.9% and there was no modification of the natural coloration. Thus, the protein hydrolysate can be used as an alternative source of antioxidant for the preservation of refrigerated meats. |

Winged Bean cultivars,'fingeWB-21-8 and Siempre WB-12-11, were grown with complete fáctorial soil fertility experiments for P, K, Ca, Mg, and S combinationson a Typic Eutrustox (dark-red latosol) from Central Brazil. Nitrogenase (C2H2 reduction), growth, and associated nodule enzyme parameters and composition were determined at anthesis. Highly significant increases in nitrogenase activity levels resulted with applied P and K for both cultivars with significant increases for Ca additions. Growth,,nodulatíon and cytosol enzyme activity levels of GOT, GDH, GS and GOGAT all increased significantly with applied P, with the exception of GDH to applied K. a KG was increased to highly significant levels with K treatment. Cytosol composition was increased sígnificantly for each plant nutrient element contained in the treatment combinations. Highly signíficant inverse retroversion existed for K and Na. Na was negatively correlated with every parameter determined in these studies for both cultivars. Practical application of these data include the requirement for adequate available soil K and P for increased symbiotic N fixation and NH4'incorporation into amino acid components of the host legume symbionÊ |
