Restructuring Passiflora Cincinnata Fruit Pulp: Influence Of Hydrocolloids [estruturação De Polpa De Passiflora Cincinnata: Influência De Hidrocoloides]

This study evaluated the effect of mixtures of alginate, low methoxy pectin and gelatin on characteristics of P. cincinnata fruit gels, containing pulp with high soluble solids content (50 °Brix). The results of a central composite design showed that the models obtained, except for water activity and pH, were predictive. Gelatin was an important factor affecting firmness and colour parameters since higher concentrations of this hydrocolloid, combined with alginate concentrations greater than 1.3% and pectin quantity up to 1.26%, could be used to obtain clear yellow products with firmness greater that 1.2 kg.311160166(2000) Official methods of analysis of the Association of Official Analytical Chemists International, , ASSOCIATION OF OFFICIAL ANALYTICAL CHEMISTS-AOAC, 17th ed.

3-D printed band-pass combline filter

This article describes a fourth-order 3-D printed combline filter with a Chebyshev response, operating at central frequency 3 GHz and having a 3% fractional bandwidth. The filter is designed using the coupling matrix theory, fabricated, and experimental results are presented. Comparison between simulations and measurements shows good agreement
