Inactivation of Alicyclobacillus acidoterrestris spores by high pressure CO2 in apple cream

Alicyclobacillus acidoterrestris (A. acidoterrestris) is a bacillus-type spore former that causes significant alterations in fruit products. It is highly resistant to typical pasteurization regimes; thus, this work explored the use of high-pressure CO₂ (HPCD) for its deactivation in apple cream. The assays were conducted in a high-pressure apparatus where the cream was placed in an agitated vessel and the CO₂ passed over under different operating conditions for distinct periods of time. The HPCD was able to deactivate the A. acidoterrestris spores in the apple cream by four orders of magnitude at 30 °C and 10 MPa. On the other hand, the lethal effect of HPCD was independent of the thermal effect since the application of dry heat without CO₂ at the same temperature did not cause any A. acidoterrestris deactivation. The important variables in terms of improving the method were the flow regime and the way to put in contact the HPCD and the cream. Finally, the HPCD treatment did not affect the most important sensorial and rheological properties of the cream; although there was a slight reduction in the vitamin C content due to thermal degradation.

Cernuda, poeta de un sur imposible

This article examines the poetics that Luis Cernuda developed throughout his life in connection with its sublime illusion of a genuine Spanish south through the romantic recreation he made of his native Seville, in several texts written from exile: they are various poems of The Reality and Desire and the essays Digressions on Romantic Andalusia and History of a Book, and, above all, the autobiographical prints from Ocnos, in which Albanios sensitive experiences reflect both the meditative elegance of Cernudas childhood and adolescence and the utopian promise of a true relationship with the world beyond the social hypocrisy of bourgeois capitalism and the coercion of Francos dictatorship. My intention in this article is to weave innovatively, in a consistent and documented way, the biographical events with the artistic intentions of the poet, to reveal original interpretive links between desolate reality and the desire for transcendence in his strange lyrics.This article examines the poetics that Luis Cernuda developed throughout his life in connection with its sublime illusion of a genuine Spanish south through the romantic recreation he made of his native Seville, in several texts written from exile: they are various poems of The Reality and Desire and the essays Digressions on Romantic Andalusia and History of a Book, and, above all, the autobiographical prints from Ocnos, in which Albanios sensitive experiences reflect both the meditative elegance of Cernudas childhood and adolescence and the utopian promise of a true relationship with the world beyond the social hypocrisy of bourgeois capitalism and the coercion of Francos dictatorship.

El mar, absoluto literario. La influencia del Romanticismo alemán en la Renaixença catalana = The sea, literary absolute. The German Romanticism influence in the Catalan Renaixença

Literary theory of the Renaixenca on the vitalism of the creative faculty comes from the poetic of the imagination of German Romanticism which investigated in literary absolute through the contemplation of the sea as the artist infinite mirror. Case in point is the work of Maragall.
