The cider sector has undergone considerable changes over the last few years. With technological advances, the traditional, at times conservative, methods have experienced great changes. New systems have been introduced into the tolares (the cider-making plants), incorporating the continuous washing of the apples, new types of pressing and polyester-coated stainless steel recipients, refrigeration, etc. Also the idea that certain cultural concepts based on concrete observations often need scientific confirmation has also evolved, enabling the adaptation and diversification of traditional procedures while maintaining the quality of the cider at all times.
The criteria for evaluating a product have to be defined and assessed taking the nature of the product into account. In the case of cider, the intrinsic value of the raw material – apples – is the foremost element of this quality. A second group of factors include a number of different, generally spontaneous reactions, favourable or otherwise, that are produced after the picking of the apples, influenced by the ripeness of the fruit and hygiene conditions when handling. Finally, the changes that may be produced in the cider, as a function of the conditions and duration of storage, have to be understood and taken into account.
The aim of the work taken up in this Report is to contribute to the enhancement of knowledge about the factors that affect the quality of cider produced in the Basque Country. The analytical techniques used are the usual ones in this foodstuffs field: enzymatic and liquid-liquid and gas-liquid chromatography. New analytical applications of a more recent technique have also been developed: high-resolution nuclear magnetic resonance (NMR) spectroscopy.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
