Biosensor system ensures quality and efficiency in the fruit juice industry

26.05.2008
Lactic acid-producing bacteria (LAB) are essential constituents of foodstuffs such as juice, vegetables and cereals.

They are traditionally used for the production of fermented foodstuffs and probably contribute to fouling and spoilage. The occurrence of LABs is often not detected for several days, but then their number increases dramatically.

QUALI-JUICE is an EU-funded collective research project which is able to detect quality deterioration by using a biosensor system. Countermeasures can be immediately initiated und thus economic loss prevented. The 17 international partners from science and industry recently presented the pre-liminary results from the project, which was launched in 2005, in Padua/Italy.

Many factors influence the price consumers have to pay for juice. In addition to raw materials, the efficiency of the production process and output are also critical. The objectives of QUALI-JUICE are to reduce production costs by 3 percent and to improve the productivity of the fruit juice industry by around 80 percent by decreasing lost output. The project is running under the EU's Sixth Framework Research Programme and has a total budget of 1.6 billion Euro, of which 1 billion Euro is funded by the European Commission. The achievements realised in 30 months of project work were presented during the last meeting. Results from tests with three offline sensors under real conditions were compared, in order to find the best available component for the process.

Since construction features lead to significant differences in performance, power consumption and price, the choice of a suitable sensor system is a core challenge. The cost for a sensor system varies from 500 to 7000 Euro, for example. Online sensor systems were tested too, however juice manu-facturers clearly prefer the offline system because installation is easier. "Three efficient offline systems are currently being examined in long-run test series at the facilities of those manufacturers who are participating in the project. Depending on requirements and investment cost, all three sys-tems offer certain advantages", sums up Dr. Hauke Hilz from ttz Bremerhaven. The research service provider is co-ordinator of the QUALI-JUICE project.

Deterioration in the quality of the fruit as a result of storage, climatic condi-tions or construction defects in production is mostly the cause for subse-quent bacterial contamination. With the help of a biosensor system, con-tamination can be detected within minutes. By comparison: Conventional analysis methods are much more complex and need at least 12 hours to deliver a result. By then, the juice can already be spoilt.

If he is aware of contamination at an early stage, the manufacturer can pasteurise the juice and use it as usual. Since this measure consumes en-ergy and thus raises production costs, it should only be introduced when there is an acute risk of spoilage. In this way, quality assurance is guaranteed and can be offered at a fair price to the customer, since efficient production with minimum waste means a process for the manufacturer where costs are optimised.

A two-level programme is foreseen which will disseminate this knowledge to industry: Firstly, European associations are trained in order to pass on the know-how to their members in the next step. The considerable demand experienced at workshops already held in Poland, Austria, Slovenia, Romania and Spain are evidence of associations' major interest in learning more about the user-friendly QUALI-JUICE technology. By the end of the project in October, various systems will be ready for market and becoming well known in the fruit juice industry.

ttz Bremerhaven is a market-oriented and independent provider of research services. At four locations in Bremerhaven, ttz staff conduct applied research and development work in the following fields: Food technology and bio process engineering, analytics, health technologies, organisation and software, as well as water, energy and land use management.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
