AZTI has drawn up some 40 tables for freshness specific for the most important commercial species in southern Europe, including fish and shellfish. The sensorial method, known as QIM (Quality Index Method) and introduced into Europe some years ago, is being applied to a greater number of species, including some in the frozen state. Concretely, for species of interest in our waters, AZTI has specific schemes for each species of commercial importance that the inspectors use.
Evaluating the freshness of fish is a common and essential practice for the industry: Freshness is an attribute that is considered objective as defined by a combination of sensorial, physical, biochemical and microbiological parameters. The human senses play a fundamental role in this assessment, which we call sensorial evaluation.
The most important sensorial characteristics for raw fish are its aspect, including its colour, smell, and its texture. Besides, other characteristics related to the species, the origin, handling and intrinsic defects or produced during processing may be evaluated by sensorial means.
The Quality Index Method (QIM) used by AZTI, is based on the objective evaluation of certain attributes of fresh fish (skin, eyes, gills, etc.) using a points system (from 0 to 3). No sample can be rejected based on just one criterion, given that several attributes are taken into account simultaneously. The total QIM points score is not influenced by small differences in the points for any one attribute. The lower the points score, the fresher the fish.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
