Quality is Going to the Dogs.

Don’t worry, it’s a good thing.

This week, BUCHI Product and Application Specialists mingled with pet food suppliers and manufacturers at the Petfood Forum 2019 in Kansas City, MO. Some key topics on deck for event speakers include nutrition, labeling, product development, safety and manufacturing.

BUCHI Laboratory Solutions can help keep the fur kids happy and healthy.

Did you know BUCHI has its paws in the formulation, quality control and labeling aspects of the pet food industry?

Formulation

Our spray dryer and freeze dryer equipment can be used to develop innovative, nutritious and shelf-stable products for happy, healthy pets. These technologies have been used to optimize stability and bioavailability for pet food ingredients, including: natural products, amino acids, proteins, vitamins and oils.

Quality Control

WATT Global Media conducted a survey and identified raw material ingredient quality as the top concern among surveyed Petfood Forum registrants. BUCHI provides expertise and laboratory and process equipment which helps to address quality standards at various stages along the pet food value chain, from raw material intake, to in-process quality control, to finished product testing to validate label claims.

The multi-axis plot shown below is a type of decision tree to determine which is the most appropriate method to select for protein determination, comparing Kjeldahl (red line), Dumas (yellow dashed line) and NIR (blue dashed line). For example, if your current need is for a high-speed analysis with a small environmental footprint, suitable for moderate sample type variation, then NIR is a good choice. If labeling compliance is of chief concern, with potential to adapt methods to broad variation in sample types, then Kjeldahl is a better selection.

Raw material inspection is an important component of a quality control program. Understanding the actual quality and parameters of incoming materials can help avoid process or nutritional deviations that occur because of out-of-spec ingredients. There is also an economical component: formulate closer to target and minimize issues like “protein give-away,” or avoid product recalls due to mislabeled or contaminated ingredients.

Near-infrared spectroscopy is one tool in the analytical toolbox that has been useful for establishing quality in raw ingredients, from grains to raw meats. The speed of analysis is well-suited for a quick quality check against Certificates of Analysis upon receipt of supplied goods.

Typical parameters measured by NIR in meat products include: protein, fat and moisture. For meat applications, color, pH, salt, starch and collagen content may also be implemented. These and other calibrations may be further refined with the addition of samples representative of the ingredient suppliers used within any production scheme.

Properties of raw meat ingredients can be monitored at the time of their production, with installation points over a conveyor belt, directly in product pipes or processing equipment including deboners, grinders or mixers. An example of online measurements of protein, moisture and fat content of minced meat at a mixer has been described in a BUCHI short note . These same calibrations can be applied in-line or off-line for the pet food manufacturer who sources meat from a supplier. Large premium meat producers such as Mircana have successfully implemented this equipment to make real-time corrections to processing deviations at the mixer.

Be a Food Analysis Champion!

Save time with efficient incoming goods inspection

New BUCHI campaign delivers 3 e-booklets to create Food Analysis Champions!

beattheclock

Every day, food producers undergo myriad processes and procedures designed to achieve a quality product and (hopefully) a profitable business.

The loading docks and warehouse serve as initial points of contact for ingredients and foodstuffs that will become integrated into delicious (and sometimes nutritious) food products. It is the obligation of the producer to ensure that they are obtaining the highest quality and correctly priced goods prior to feeding those ingredients into the production process.

Our first booklet provides insight into challenges and opportunities related to incoming goods inspection, including:

  • Typical slow-downs in incoming goods receiving
  • Tips to meeting incoming goods inspection requirements efficiently
  • Benefits of using fast, non-destructive NIR analysis for testing incoming goods
  • Improving time-to-result for classical reference methods (i.e. extraction and Kjeldahl)
  • Sample NIR and classical testing applications to help you save time!

Download this complimentary resource, and stay tuned for future additions to the series, including: production and finished goods control!

For some nice (and enlightening) lunch break entertainment, watch our Food Analysis Champion, Max, save the day when production is halted due to QC backlog in the BUCHI animated video short series for “Beat the Clock.”

 

Feed Manufacturing: Profit with In-line NIR Process Control

The BUCHI Crew is hitting the road this week for the 2017 International Production & Processing Expo (IPPE) in Atlanta, Georgia. Sounds peachy! Find us in Hall C, Booth 205.

IPPE is hailed as the largest annual trade show for the poultry, meat and feed industries. The show focuses on innovation, education, global reach and networking. So, what does BUCHI have to offer these industries? Let’s talk about real-time process monitoring and how it plays into profitability. 

Is moisture content in feed synonymous with profit margin? Talk to a feed producer and you’re likely to see a head nodding in agreement.

How valuable would it be to have a continuous read-out of the moisture content of your feed at points along the process where you can still adjust your process to reach a moisture target? Sounds like money in the bank, and BUCHI near-infrared (NIR) spectroscopy is a proven tool for the job. It’s also possible to monitor other critical feed parameters, like protein and fat, simultaneously.

Check out this short note showing how a BUCHI NIR-Online® process analyzer was used to monitor fat, protein, moisture and crude fiber after the mixing step in a feed operation. Or, read below for a case study at the German RKW mill that produces 75,000K tons of mixed feed annually and uses BUCHI IR-Online® to improve profitability.

The production process

At the RKW Kehl production facility the process begins with a check of raw materials for upcoming orders. The feed is predominately composed of soy and maize cereals, with minerals, vitamins and amino-acid supplementation. Feed composition is obtained by the required moisture, fat, protein, crude fiber and starch of each recipe. Due to the inherent variability of these nutrients in the incoming raw materials, the ratio of raw components needed to fulfill the nutrient profile of each recipe must be recalculated daily.

Mixtures under scrutiny

Raw materials are selected, scaled and mixed according to ordered batch recipes using the process control system. The quality control group determines whether a feed mixture falls below a required protein or fat content, or if moisture needs adjusted to meet specifications. Prior to the installation of the NIR-Online® process analyzers, the answers to these questions came from traditional laboratory analysis with long wait times. Now, the answers are streaming in real-time using the NIR-Online® device at the end of the mixing unit.

Near-infrared (NIR) light emitted from the sensors illuminates product through an installed window resulting in absorption by the sample, which is characteristic of its composition.  These readings are visualized in process charts by personnel in the switch room. If preset parameters are over- or under-run, corrective adjustments can be made immediately. Integration of the NIR-Online® products with the existing process control system provides the opportunity for automatically generated, highly detailed process documentation.

In-line control

“[Because the process can be stopped or adjusted early in production if specifications are not met] the utilization of NIR-Online® has minimized expensive rejects and complaints,” said Mr. Lühr, as he described the financial advantages of the NIR-Online® solution. “This benefit is further increased with the possibility of adjusting moisture content in real time.”

The NIR-Online® process software calculates the difference between the in-line property measurement and the batch set point without stopping production, ensuring moisture addition is precisely controlled for each batch.

“If we are able to converge within 0.5% of the moisture set point of a batch, we can sell more than 375 tons of additional mixed feed per year – a substantial benefit. “The investment in NIR-Online® technology will be paid for in a few months”, Mr. Lühr stated.
