Representative Sampling: Important in Nut Butter Packaging

Nut Butter Packaging

Many co-packaging companies provide distributors with multiple types of nut butter products from one processing plant, including everything from smooth and chunky peanut butters to almond butters and organic products. Simultaneously, food health and safety are co-packers top priorities to avoid recalls due to salmonella, e-coli and other contaminants.

Faced with these pressures, co-packers are looking for adaptable automatic sampling solutions. These solutions help them ensure that samples represent the entire lot or batch, keep up with continuous improvement projects, and maintain their Safe Quality Food (SQF) status.

Contamination Risks in Packaging Nut Butters

It's the co-packer's responsibility to ensure that each of their customers' recipes meets specific requirements. What's more, co-packers must ensure they're producing a consistent, high-quality product. However, this can be difficult, as process equipment is often prone to contamination:

  • From new process equipment
  • Ingress from environmental sources or foreign material introduced to the equipment during maintenance
  • Internal contamination from moving parts within equipment
  • Cross-contamination when one product comes into contact with another product during processing

Cross-contamination is particularly challenging because co-packers must ensure that flavors and product consistencies don't mix.

Additionally, they need to ensure that organic products don't come into contact with non-organic ingredients. That's why co-packers usually produce organic products before non-organic products to reduce the risk of cross-contamination.

Current Sampling Protocols Are InSufficient

Most nut butter producers use a "grab-style" procedure. This is where an operator takes a jar off the production line or collects finished, unpackaged product in a container as it's being packaged into bulk containers before sending it for sampling analysis.

However, grabbing a single jar from a pallet of 1,000 (or more) jars isn't an exact representation of that entire lot. Collecting a sample in a container is also risky. The operator takes a single snapshot of a large amount of product, which could fail to identify contamination in the lot or a deviation from the required recipe.

Automatic Sampling Delivers Quality and Consistency

Today's co-packers need a reliable method to produce representative and composite samples effectively by consistently collecting small amounts from a product stream on a timed basis. This approach contains a sample from every jar or package, ensuring a consistent, accurate and representative sampling program.

Some nut butter co-packers have adopted the N-60 sampling method, considered the gold standard for obtaining a lot or batch representative sample. Some samplers help co-packers replicate this sampling method and produce 60 samples per lot or batch.

Automatic samplers also help co-packers:

  • Meet sanitary standards
  • Prevent introducing operator bias to the process
  • Adapt to current methods based on size and connection style
  • Prevent internally generated contamination with FDA-approved O-rings and sterile collection bags/jars
  • Prevent microbial growth within the equipment
  • Regularly clean and maintain equipment with an easy-to-disassemble and reassemble design
  • Automate sampling to reduce interruption and free up personnel for other tasks
  • Meet a variety of centipoise (cP) measurements to work with the natural variance of viscosity in nut butters

Sentry Equipment offers the automatic samplers and expertise co-packagers need to sample at every stage of the production process, ensuring your product and bottom line remain safe. We offer samplers that can handle higher viscosity than any other competition – up to 300,000 cP.
