PHILADELPHIA, PA –– Xylem’s Bellingham + Stanley and SI Analytics brands team up with key European fruit juice manufacturers, applying the latest automation techniques to common quality control measurements in an effort to reduce production losses and to minimize the labor burden associated with the latest regulatory requirements.

Xylem’s Bellingham + Stanley and SI Analytics brands will be exhibiting in booth # 1449 at Pittcon 2013, March 18-21 in Philadelphia, Pennsylvania.

For many years, beverage manufacturers have utilized digital refractometers as their primary instrument for measuring the final dilution ratio (°Brix) of re-constituted fruit juice. This is to not only assure product quality but also to reduce losses by tightly controlling concentrate yields. Alongside these refractometers, automated titrators are also used to ensure that the citric acid

is maintained to the required specification.

For most fruit types the measurement of °Brix has been a successful analysis for dilution ratio. But for one of the most commonly produced juices, the high accuracy measurement achieved by the latest digital refractometer technology has unmasked an erratic behavior in orange juice that prevents tighter dilution control. This in turn negates any opportunity of cost reduction by way of lowering target values without the risk of compromising minimum specifications defined by regulation.

Over the past two years leading refractometer manufacturer – Xylem’s Bellingham + Stanley brand – has partnered with a major fruit juice producer to develop the Pro-Juice Refractometer, which can achieve the same high accuracy results for orange juice as it can for other fruit based juices. By focusing on the practical handling of the sample prior to high accuracy measurement, Bellingham + Stanley has designed the Pro-Juice Refractometer based on the world leading technology used in the RFM340+ Refractometer. As a result, a measurement accuracy of 0.01 °Brix for sucrose solutions and more importantly a reproducibility of 0.02 °Brix between orange juice samples is achieved, regardless of temperature deviation or operator skill level.

By adopting the use of the Pro-Juice Refractometer, manufacturers of orange juice can operate closer to the lower threshold of their specification without running the risk of compromising the final product. In so doing, there is an opportunity for cost savings and higher profits from increased concentrate yield.

Transparent audit trails within the food and beverage industry is of paramount importance, not just for food safety concerns but also as evidence of product authenticity. Fruit juice manufacturers the world over are faced with an ever increasing need to minimize costs, so manufacturers look towards automation of repetitive everyday tasks in order to keep production overhead to a minimum.

One task that can be automated is the measurement of citric acid within the re-constitution phase of orange juice production. This is a task that Xylem’s SI Analytics brand has successfully accomplished, and they’ve done so by applying automation to their successful Titroline instrument at an Austrian fruit juice producer. The key requirement to measure citric acid content in orange juice by titration is dispensing precision, and the burette is central to this process. SI Analytics’ titrators, the TitroLine 6000/7000 feature the piston burette TITRONIC 500 that not only achieves precision but it can also measure other acids in fruit juices as well.

The final step for automation is to load an autosampler with pre-weighted samples, program the Titroline titrator via simple PC software to perform the citric acid analysis, and key personnel are then freed up from time-consuming manual titrations.

Xylem will showcase its analytics solutions and applications in booth # 1449 at Pittcon 2013, March 18-21 in Philadelphia, Pennsylvania.
