PEACHES and Peers

How to distribute resource locators is a fundamental problem in PKI. Our PKI Resource Query Protocol (PRQP), recently presented at IETF, provides a standard method to query for PKI resources locators. However the distribution of locators across PKIs is still an unsolved problem. In this paper, we propose an extension to PRQP in order to distribute PRQP messages over a Peer-to-Peer (P2P) network...

Control of Enzymatic Browning in Frozen Peaches

Separation and characterization of endopolygalacturonase and exopolygalacturonase from peaches.

Two polygalacturonases (PG I and PG II) have been separated from extracts of ripe peaches (Prunus persica) by chromatography on Sephadex G-100. PG I hydrolyzes polygalacturonic acid from the nonreducing ends of the molecules, releasing galacturonic acid as the product. It functions optimally at pH 5.5, requires Ca(2+) for activity, and hydrolyzes low molecular weight substrates most rapidly. In...

Mealiness assessment in apples and peaches using MRI techniques.

Mealiness (woolliness in peaches) is a negative attribute of sensory texture that combines the sensation of a desegregated tissue with the sensation of lack of juiciness. In this study, 24 apples cv. Top Red and 8 peaches cv. Maycrest, submitted to 3 and 2 different storage conditions respectively have been tested by mechanical and MRI techniques to assess mealiness. With this study, the result...
