NEW IC BUFFALO KIT: Detection of cow’s milk in buffalo’s milk.

Escrito por admin el . Posteado en Uncategorized

The unknown mixture of milk from different species is a common fraud in the cheese sector. The different prices of milk species tends to adulterate the expensive with those of lower cost. This adulteration is especially important for cheese makers, not only for economical reasons, but also because unknown milk mixtures produce changes in the final sensory properties and reduce the product quality. Besides, cheese producers need to assure that pure cheese does not contain milk from other species for labelling purposes.

The fraudulent addition of cow´s milk during the manufacturing of water buffalo Mozzarella cheese has increased in recent years, due to the growing market demands in EU (European Union). Mozzarella cheese is registered with Protected Designation of Origin (PDO) that demands it only can be made from water buffalo´s milk. Finally, the European Regulations concerning cheeses from different species milk, buffalo included, demand to verify by appropriate controls that no cow´s milk has been incorporated.

The NEW IC BUFFALO is a qualitative test to detect the presence of cow’s milk in buffalo´s milk. The kit is an immunochromatography test based on the detection of bovine immunoglobulins (IgG) in milk samples. This test can be used with fresh, pasteurised, whole or skim milk. The IC BUFFALO kit does not require any technical skills or lab equipment and can allow cheese producers to make fast decisions, which can save them money and ensure the quality of the final product.

ZEU-INMUNOTEC offers other rapid screening test kits to identify the presence of cow’s milk in sheep and goat milk (IC-Bovino), or alternatively to detect goat’s milk in cow’s (IC-Caprino). ELISA tests (RC-Bovino and RC-Caprino) are also available for quantification of the milk mixture.

Chinese, German and north American researchers has been able to produce what varieties compatible for celiac patients. Gluten is a complex mixture of several proteins known as gliadins. In a single bread wheat variety is comprised of up to 45 different gliadins. Some of these proteins induce an autoimmune reaction in celiac patients. The only effective therapy is strict dietary abstinence from food with gluten, but is quite difficult to comply with. Besides, following a gluten-free diet has adverse influence on gut microbiota causing digestive problems. In this work, researches have been avoiding the expression of the enzyme that controls the synthesis of some gliadins. These wheat varieties showed a 76.4% reduction in celiac response gliadins. It is has claim that these modified wheat would be able to bake food suitable for celiac patients. In addition patients would allow consume non immunogenic gluten avoiding adverse effects of a gluten free diet. Original source: Wen, S. et al.

More than 100 participants gathered at the first conference organized by the Società Italiana Ricerca Applicata Molluschicoltura  (SIRAM) at the University of Teramo in Italy. Different relevant subjects such as the shellfish situation in Europe and the role of DG Mare, or the national shellfish production were discussed.  With regards to the shellfish safety, the director of the National Reference laboratory for marine toxins presented the validation of LC-MS method for lipophilic toxins monitoring. ZEU INMUNOTEC together with its local partner DIESSECHEM presented the kit OkaTest for determination of OA-toxins in shellfish OkaTest is a functional assay able to detect the toxicity due to these type of toxins in shellfish samples. The kit is rapid and easy-to-use and it can be used as complementary to the reference method for lipiophilic toxins monitoring. OkaTest has been inter-laboratory validated by 16 labs and complies with the European Reference lab for marine toxins requirements and current regulations EC No.15/2011

Once again the shellfish growers gather together at the ASSG annual conference in Oban, Scotland. During the meeting many interesting topics were covered. Innovation in ormer farming and mussels, pearl farming around the world and the opportunities and challenges for the aquaculture industry. The seafood in schools programme was also presented. This is an innovative project to teach new generations how to enjoy eating shellfish. The conference also had the contribution of top scientists who updated the audience on four research projects on mussel live transportation or management of algae toxins. ZEU-INMUNOTEC presented a functional assay for determination of OA-toxins in shellfish –OkaTest. Marine toxins management is an important issue for shellfish growers and regulatory bodies. OkaTest is a very easy assay for detection of all okadaic acid diarrheic toxins commonly found in Scottish coastal areas. The test can be used complementary to the reference method for official testing or by shellfish producers running their own checks.

The First Distributor’s Meeting organized by ZEU INMUNOTEC took place in Barcelona last October.  Distributors from Asia, America and Europe attended the event. During the meeting, ZEU INMUNOTEC presented the last updates in detection of antibiotic residues tests. Discussions focused on Eclipse 3G, which is the official test in France for inhibitors residues in milk. Eclipse 3G is therefore used by all interprofessional labs, big dairy players and farmers. Technical aspects of the test as well as current actual market share and opportunities were looked into. The new Explorer 2.0 for detection of inhibitor residues in meat and other food matrices was introduced to all attendees during the meeting. Explorer 2.0 an easy-to-use test for screening of antibiotics residues is the perfect tool to ensure that meat products comply with antibiotics residues regulations. Explorer detects most used antibiotics groups at the European MRLs. Analytical trends in food allergens detection, latest developments in dairy adulterations or algae toxins analysis were also discussed. The meeting was characterized by its extensive audience participation, networking and communication. During the second day all distributors had the opportunity to  ​​make comments and suggestions in a roundtable discussion. Moreover, French and Greek distributors spoke about real cases of success referring to the peculiarities of their markets and commercial cooperation with ZEU INMUNOTEC. After the meeting, Barcelona Highlights were visited and all participants finished the day with a pleasant dinner in the Olympic port tasting some of the most typical dishes from the Mediterranean. ZEU- INMUNOTEC extends its appreciation to all attendees who travelled to Barcelona to be at the meeting and encourage them to continue working and collaborating with new ideas to offer new products and services.
