Passion fruit peel is an agro-industrial waste that with added value can be used in the food industry. The purpose of this work was the physicochemical, functional and rheological characterization of passion fruit shell flour (HCMr). Physicochemical, functional and rheological analyzes were carried out. The humidity value of HCMr was 11.25%, this is within the requirements of Peruvian standards. Protein values (5.14%) are low compared to cerelae flours. The total dietary fiber value was 63.88%. The total values of polyphenols and antioxidant activity were 504.75 mg G.A.E./100g and 1520.49 µmol ET / 100g respectively. The water retention capacity value was 12.93 ml retained water / g. The rheological values were: 702 consistency farinographic units with 14.02% humidity. With these characteristics obtained, HCMr can be used as an ingredient or food substitute and thus obtain products with...

In this research work has been synthesized and characterized by chemical route monometallic and bimetallic nanoparticles Core / Shell (Au / Ag), using two-step method involving the preparation of a solution of nuclei formed by gold nanospheres and its union with the armor formed by silver nanospheres; to this, the final size of the nanostructure, intimately dependent kernel size for that matter studied and experimentally examined the influence of parameter variation in the synthesis process._x000D_ It basically studied the influence of synthesis parameters on the gold nucleus, then it choose the best conditions and make the coating and produce silver bimetallic nanostructures. Variations were such as: Method of synthesis of the nanosphere, temperature stabilizing cetyltrimethylammonium bromide (CTAB) 65, 75, 85 and 95 °C, precursor Origin of chloroauric acid (HAuCl4) Stabilizer Type hom...

Bioremediation is one of the methods to eliminate metallic pollutants from leach mining. Its use provide technical and economical adventages compared to ionic exchange or membranes. In bioacumulation, a type of bioremediation, metal ions are incorporated into microorganism cells, its inconvenient is necessity to prepare cultures media and special conditions to mantain biomass. On the other hand, biosorption uses natural polymers, called biopolymers; functional features of these macromolecules give them metallic adsorption capacity in predetermined conditions; some of them are algae derivatives like alginates, poliamides from hair, colagen from bond tissues or chitin and chitosan extracted from crustaceous shells. Specially chitosan could be obtained from chitin, second most abundant biopolymer in nature next to cellulose, its main source is food industry of prown, shrimp, crab and simila...
