Food manufacturers need to ensure that the cleanliness of their production lines is maintained to the highest standard to avoid contamination of product. Aseptic drives are carefully designed for applications where regular washdowns are required to maintain a clean environment. The motor is designed so that a fan and cooling ribs are not required, thereby allowing for a completely smooth outer casing with a non-drive end which is sealed. This eliminates any dirt traps on the motor casing and also prevents re-infection of the local environment caused by air movement from a cooling fan. The design also includes a very high level of ingress protection, up to IP69K, which is a special designation for washdown applications involving high pressure, high temperature water. In addition, the aseptic drive is painted using an acid and alkali resistant formula, which can withstand chemicals with a pH range of 2 – 12. As a result the new drive system can withstand the cleansing solutions and disinfectants that are commonly used within the food industry without affecting its performance. A combination of aseptic motor/gearbox packages has been developed with variable frequency drives (VFDs) to enable a very efficient package to be installed. The majority of the drives use 0.75kW motors, with some smaller 0.55kW units and most of these, nearly 80%, are coupled to the BK20 hollow shaft bevel gearboxes. When installing a large number of motors onto a production line, it is important to maintain high energy efficiency so that the return on investment can be minimized. All of the aseptic motors from Bauer are rated IE3 energy efficiency class and when combined with the VFD they can deliver optimum energy consumption and running costs. By designing a system with a large number of common components, the engineers were also able to minimize the spare parts inventory while still ensuring the most energy efficient and reliable design. In addition to this, the motor itself is equipped with thermistors and class F insulation, which makes it suitable for control by VFD and the thermistor connections are combined with the motor connections in a stainless steel, round connector which allows quick and simple motor connection while still maintaining the hygienic aspect of the design.

Four-ply aseptic bags
The new four-ply aseptic bag solves the issue of flex cracking, a very frequent problem causing de-lamination, de-metallisation and eventually breaking the bag. This happens frequently and can jeopardise product preservation, caused by the continuous movement of the bag content during handling and transport, which leads to erosion of the bag structure. The use of superior resin recipes and the addition of a fourth inner ply, has created an aseptic bag with an extremely flexible structure, which maintains the usual barrier and mechanical properties, but performs exceptionally well against flex cracking. The new 22OI bag is available in the standard and extra-high barrier (with aluminium foil) versions and it is particularly suitable for low-viscosity products such as citrus fruit concentrates, juices, apple juice, purees and diced tomato.

NutraT line
Extracting natural ingredients from the Mediterranean diet is the expertise of Nutrafur S.A. now a member of the Frutarom group. Nutrafur S.A., Alcantarilla, Murcia, Spain, developed NutraT, a line of ready-to-use soluble powder formulas that dissolve easily in water, soft drinks and dairy products. Once the powders dissolve, the beverage stays clear, without turbidity, and deliverS fresh fl avour. The NutraT line offers water and soft drink manufacturers the ability to fortify their products with exceptional natural extracts that typically are not watersoluble. This opens new opportunities to develop products with new flavours that include ingredients delivering the essence of a healthy Mediterranean diet. OliveT contains all the beneficial compounds from the olive, and provides more than 25% olive polyphenol content. Just 5 g/250 ml liquid provides 43-45 mg of olive polyphenols. Recent studies demonstrated that these olive extracts can help regulate blood pressure and support blood circulation. CynaxT is an exotic formulation that brings the health benefits of artichokes, with a 5% polyphenol content. Recent studies demonstrated that artichokes can help regulate serum cholesterol levels, thanks to the plant’s choleretic and diuretic properties. A single 5 g/250 ml liquid shot of CynaxT mixed with water or another beverage provides 25 mg of polyphenols and supports renal water elimination and healthy blood circulation. RosT has a high-phenolic compound content with a significant antioxidant capacity and preserves its pleasant taste. Products fortified with RosT allow beverage producers to position their product as a “beauty from within” drink or as a “better sleep” aid. RosT’s 5 g/250 ml provide 50 mg polyphenols. CitroT is a soluble extract with a high bioflavonoid content. Citrus bioflavonoids are known to provide a protective effect on the cardiovascular system. A concentration of 5 g/250 ml liquid provides 340 mg of citrus bioflavonoids. All four mixes are produced using sustainable sources, are heat stable at up to 70°C, and both Kosher and Halal certified. NutraT can be incorporated into a food or beverage matrix, such as water, fruit juice, yoghurt, kefir or milk, or as a final product in powder sticks, sachets or inside of a powder-dispensing bottle cap for preparing enhanced beverages immediately before use.

Delvotest T
DSM Food Specialties’ Delvotest T was chosen by QLIP, Dutch partner in quality assurance in the agrofood chain, as the national reference test to detect antibiotic residues in milk. The broad spectrum test was selected because of its high sensitivity and reliability. The test is fully compliant with Dutch dairy regulations, promoting a high quality milk supply throughout the whole dairy chain, from farmer to dairy to consumer. QLIP is commissioned by Dutch dairy companies to determine the composition and quality of farm milk samples. The analyses they perform meet the specific requirements of the official Dutch dairy regulations and detect the most relevant residues at or below the European Maximum Residue Levels (MRLs). Delvotest T is a broad spectrum test which identifies a variety of antibiotics at or below EU MRLs with higher sensitivity for tetracyclines than any other microbiological screening test. QLIP selected Delvotest T because the test is closest to the aimed detection level and because of its robust performance and consistent results. In the Netherlands, there is a successful programme in place to reduce the usage of antibiotics in general. A test like Delvotest T is an important tool to safeguard the suitability of milk that forms the basis for the broad range of Dutch dairy products.
