process. When they went to review the incoming ingredient inspections they found that records were not completed on every load. The persons responsible for inspecting the loads and completing the records had not received training on food safety and only knew that they needed to unload so many loads of ingredients every shift. The operations team felt the inspections and record keeping slowed them down and nobody looked at it anyway. The team could not determine if the metal came from an incoming


ingredient or from their process. Their prerequisite programmes were not being followed and not reviewed by a management team. The control point caught the food safety hazard but at a large extra cost to the company. The weak training and ingredient PRPs allowed for a food safety hazard to contaminate the final product. The pet food safety hazard


could have been prevented if the facility had completed food safety training and verified and followed their incoming ingredient prerequisite Programme was being followed. The facility went back and completed pet food safety and PRP


training for all their employees. The facility was then able to quickly determine that a supplier had metal contamination in their product. The facility was able to reject the shipments and work with the supplier to identify and correct the hazard. The PRPs were able to prevent the hazard from entering the process in the first place.

Premier Pet Nutrition launches 3 innovative pet food calibrations to enable pet food manufacturers to

maximise their NIR machine’s capabilities. Premier Pet Nutrition (PPN) is the nutrition partner for pet food manufacturers, providing technical nutritional support, custom pet food premixes and NIR calibrations as part of their package to the pet food industry. PPN has developed with its sister company Aunir, 3 innovative


petfood-specific calibration factors for its nutrition partners to enable them to maximise the performance of their existing NIR machine (Bruker, Buchi, Foss, Unity, Thermofisher etc) The 3 new pet food calibrations are:


1. Cook Value. The Cook Value calibration measures how well a dry pet food has been cooked, stating the level of starch gelatinisation (%). The cook level of a pet food affects its palatability and digestibility and the new calibration informs the pet food manufacturer instantly how well a pet food has been cooked. It also provides instant feedback to the extruder operator if they are putting too much or too little energy into the pet food - offering significant energy cost savings at the extruder. Previously, measuring cook value has meant lengthy and costly wet chemistry analysis, with results often arriving days after the pet food has been packed. With this


2. Peroxide Value (PV) PV is a measure of the level of oxidation in fats in a pet food which has a massive influence on the palatability and shelf-life of a dry pet food. By measuring the PV using NIR it is now possible to assess quickly how oxidised the fats are and if the palatability or shelf-life are going to become issues for that batch of pet food. Using NIR to measure PV now saves both time and money compared with conventional PV analysis methods.


3. Water Activity (aw ).


Water activity is one of the most critical factors determining the quality and safety of a dry pet food. If it is too high, the dry pet food will mould and spoil due to microbial growth. The new aw


calibration gives instant


feedback on how likely a pet food is to spoil once packed. Ben Helm, PPN’s Commercial Manager commented on the


availability of the 3 new calibration factors: “The vast majority of pet food manufacturers have invested heavily in an NIR machine and want to optimise that investment. Pet food legislation and customers are setting progressively tighter quality controls and the NIR machine is quickly becoming the best route for measuring pet food quickly and accurately. These 3 new calibrations enable pet food manufacturers to use their NIR machine to test for parameters previously unachievable by an NIR machine. The calibrations can easily be uploaded to an existing NIR machine, enabling pet food manufacturers to get the most from their current machine - testing new parameters quicker and more cost effectively than before. This saves them time, money and reduces risk while producing a better quality pet food.” In addition to the new calibrations, PPN also offers a full suite of


robust and world-class calibrations for incoming raw materials and dry pet food, backed up by a decision-making and data logging system that can bolt on to an existing NIR machine. These are already widely used by pet food manufacturers. www.premierpetnutrition.co.uk info@premiernutrition.co.uk


PPN also uses NIR to verify and validate all of their incoming micro- ingredients (vitamins, minerals etc) prior to being used in a pet premix.
